Repair of VAZ 2110 starter retractor relay

It is known that a car cannot drive without a starter. It seems like a simple electric motor, but you can’t do without it. You can start a piston unit with a failed “starting” unit only from a pusher, but only for a trip to a car service specialist.

The reasons for the breakdown of such a critical mechanism are quite obvious. Most diseases can be cured if you repair the starter yourself. We list below the main sources of malfunctions:

natural wear and tear of electric motor elements;
water ingress while washing the car engine;
improper operation of the unit, for example, long periods of operation of the electric motor after starting the engine;
short circuits.

Do-it-yourself partial repair of the starter usually saves you from all this. That is, it is not at all necessary to buy a new unit entirely. Next, we will look at which specific elements fail, and how to repair the starter with your own hands.

Let us first note that according to the symptoms when turning the ignition key, it is necessary to distinguish between the types of malfunctions of the starting electric motor. If, for example, after turning the key you hear a clicking or crackling noise, then the problem is in the retractor cylinder. The latter can be completely replaced.

How to deal with the VAZ unit

First, let's look at how to repair the starter with your own hands on VAZ cars. First, let's take the very first of the cars in this line.

To repair a VAZ 2101 with your own hands, we will use the tools listed below:

set of wrenches;
flathead and Phillips screwdrivers;
sandpaper;
heads.

So, let's start work by opening the hood.

Disconnect the terminals from the battery.
We dismantle the air filter housing with the filter element.
Unscrew the three nuts securing the electric motor to the motor.
We disconnect the wires after taking photographs of the connections.
We remove the defective device.
Perhaps the so-called “pants” - the exhaust pipe - will interfere with this, then you will have to unscrew the four bolts and “lower the pants”.
We separate the retractor cylinder from the dismantled element by disconnecting the wire and unscrewing three screws. We inspect it and, if necessary, replace it completely.
After unscrewing the bolts, remove the motor casing.
After unscrewing the two bolts, remove the cover.
Separate the windings from the brush holder plates and remove the insulating tube.
Separate the cover from the collector side.
Use a screwdriver to remove the motor brushes. We measure them and replace them if necessary.
We disassemble the drive of the defective assembly unit. To do this, undo the cotter pin, then remove the drive lever, disengage the drive from the clutch, and then remove it.
We inspect the windings of the electric motor.
If necessary, we press it out, and then replace the bushings of the assembly.
We clean elements with soot or plaque. We replace failed parts with new spare parts.
We carry out assembly and installation in the opposite direction.

Note that do-it-yourself starter repair for a VAZ 2106 is carried out according to similar instructions.

Also find out where the fuel filter is located on the Hyundai Solaris and the structure of the fuel pump.

If we discuss the problem that interests us regarding front-wheel drive VAZs, then it is enough to simply consider what differences there are from the given instructions. The tools used here are the same.

However, for example, when repairing a VAZ 2109 starter yourself, you do not need to disconnect the exhaust pipe during removal from the car. Further manipulations are carried out exactly as described above.

Naturally, repairing a similar VAZ 2108 starter with your own hands is done according to a similar scenario. When repairing a VAZ 2110 starter with your own hands, it is easier to immediately remove the solenoid relay while dismantling the unit from the car by unscrewing the corresponding nuts.

However, in case of repairing the starter of a VAZ 2115 with your own hands, the electric motor can be dismantled immediately along with the retractor cylinder.

By the way, it is not necessary to replace this completely assembled cylinder if it breaks. You can also repair the starter retractor relay yourself. To do this, you need to disassemble it, inspect the retractor winding, return spring, and replace failed parts. As for domestic cars, UAZ repairs can be performed according to the given instructions from VAZ.

How are things going with other popular cars?

Now let’s touch on two more truly popular cars. Let's talk about sorting through the starting element on Oka, as well as Nexia.

To repair the starter at Oka with our own hands, we will need:

set of wrenches;
screwdrivers.

We start by dismantling the unit; it is located under the thermostat of the cooling system.

In this car, the starting device is attached to only two points; to remove it, you need to unscrew the bolt on one side and the nut on the other. But first we disconnect the wires, both from the battery, from the retractor cylinder and from the connecting block.
We unscrew the two nuts, and then remove the traction relay.
Unscrew and remove the cover casing from the collector side.
We dismantle the brush springs, locking, and adjusting washers.
Separate the cover from the body where the collector is.
We remove the brushes, then measure them; when they are worn out, they need to be replaced.
Having unfastened the cotter pin, we dismantle the lever axis.
Remove the cover from the drive side.
We remove the drive lever, then take out the anchor.
We inspect the windings of the electric motor.
We dismantle the drive coupling and inspect its condition. This clutch is also called bendix. In case of any defects in the clutch, it is easy to repair the Bendix of any starter with your own hands. You just need to replace the broken elements.
We take out the bendix spring and replace it if necessary.

These are some simple manipulations.

It must be said that in such a small car, such as the Tavria, the mounting of our treasured electric motor is also made at two points, and its design is similar. Therefore, Tavria does its own repairs in the same way.

Well, with Oka and Tavria it’s somehow easier, but if the starting unit of another people’s car breaks down, will it be more difficult? Let's see. To repair the starter of a Daewoo Nexia with your own hands, you need to prepare:

set of wrenches;
screwdrivers.

To dismantle the unit from the car - here, like all rather large cars, there are three fastenings - unscrew the nuts and disconnect the wires. You need to know that a “ground” wire is attached to the upper bolt that secures the electric motor to the piston unit.
We immediately check the drive gear; it should only rotate unidirectionally.
We disassemble and sort out the assembly in the same way as in previous cases.
We also disconnect the solenoid relay.
We remove the cover from the collector side, as well as from the drive side.
We dismantle and then, if necessary, replace the brushes.
We take out the anchor and study the windings.
If necessary, we press it out, and then replace the bushings of the assembly.
We do the assembly in reverse order.

Apparently, there are few difficulties here.
The same can be said about repairing a starter, for example, an Audi 80 with your own hands. There you need to act, practically repeating the above points.

Price and necessity of the procedure

However, not everyone decides to repair the starter with their own hands. For some, turning to a car service center may seem like a much more convenient option. For such car enthusiasts, we have compiled a table with prices for the described operation.

Lada 2110 “AGRESSOR” › Logbook › Repair of solenoid relay contacts VAZ 2110

Hi all! I haven’t written anything in the logbook for a long time. And there were no breakdowns. But a week ago I drove up to the store and turned off the car. And after 10 minutes, when turning the ignition key, the car showed no signs of life. A minute of confusion, and I try again, again zero. I went through all the possible breakdowns in my head. I opened the hood, closed the two retractor bolts with a screwdriver, the result was zero. I immediately realized that the starter had come to an end. I had to push it to start it. I drove it into the garage. I removed the starter. I started to unscrew the nut from the 2nd retractor bolt, from which the + goes to the starter. And either the thread is Chinese or I’m a handyman :). As a result, the nut came off with a piece of the stud.

Then I removed the retractor and began disassembling it. I unscrewed 2 bolts. And he began to unsolder the ends from the coil. (When you unsolder, do not pull too hard)

This is the view, without the contact group.

But the contact group itself has become in poor condition over time.

I found contacts from other retractors and chose those marked with a rectangle.

I would like to note right away that if you don’t find the contacts from the retractor, you can buy copper bolts for 6 or 8 at any auto store. I decided to put the bolt at 8 instead of 6. I clamped the body of the contact group and drilled a hole at 8. (Drill with drills incrementally, and not immediately

The next step was to make the shape of the contact, and grind it down a little on top since it was thicker.

He clamped it in a cleat and began to grind it down. I decided to also replace the second contact, since it was also in poor condition.

The finished look of the contacts sits in their places like a glove, I immediately secured them at the back with nuts.

I also decided to clean the contact plate.

I started putting it back together.

I decided to drill through the tin with a small drill so that the wires from the coil could simply be inserted into the holes and then soldered with tin.

Don't forget to put on the rubber seal.

Then I tightened the bolts of the contact group and soldered the coil contacts.

As you can see, everything can be done with minimal repair costs, rather than buying a new solenoid relay for 1000 rubles.

P/S. Please do not write that it is easier to buy a new retractor, etc. It’s more interesting for me to repair it myself than to immediately go and buy a new part!

Replacing the solenoid relay on the VAZ 2110 starter yourself

Starter and retractor relay VAZ 2110

If the car suddenly stops starting, there are no characteristic sounds before starting the engine, or a strange “humming” noise appears, then the starter solenoid relay may be damaged. Naturally, the device can sometimes work normally without showing signs of breakdown, but at the most inopportune moments the car has to be started from the pusher. In this situation, only replacing the retractor on the VAZ 2110 starter will change everything for the better. Symptoms of the malfunction are different, for example, the appearance of clicks at the relay, lack of cranking of the starter, lack of signs of life when turning the ignition key, etc. It is worth noting that replacing the VAZ 2110 retractor starter can be done with your own hands.

Typical breakdowns

Now let’s figure out how to check the starter solenoid relay on a VAZ 2110. It must be carefully inspected after dismantling.

This unit is characterized by certain breakdowns, which we will talk about.

The fastening is loose or the nuts responsible for fastening the wire end are completely loose. Everything is simple here, as you understand. You just need to tighten the fasteners.
Oxidation has formed on the windings, connections or wiring. If everything is not too serious, you can simply clean the contacts. In case of serious oxidation, it is better to replace them with new ones.
The power supply circuit has breaks. Again, you don’t need to come up with anything fancy, just replace the chain.
The armature exhibits idle operation or slow operation. Just replace the armature and that's it, problem solved.
Check the short circuit of the turns of the two windings using an ohmmeter.

Solenoid relay

The VAZ 2110 starter solenoid relay is designed to remotely turn on the electric starter motor. They ensure the clutch of the bendix (see Replacing the bendix on the VAZ 2110 starter on your own) with the flywheel crown. This element structurally consists of: a returning, contact and magnetic system, including two coils - a holding coil, connected to the control terminal and going to the housing, and a retracting coil, connected by the control element.

This is interesting: Repair scheme for Kedr Auto 10A

VAZ 2110 starter solenoid relay

The pipe where the armature is located is a core, inside of which there is a copper winding (the end and beginning of the winding are attached with terminals, one side is connected to the electric motor and the control contact, the other is connected to the control terminal and goes to the housing).

VAZ 2110 retractor clicks and the starter does not turn

The movement of the armature in the core is carried out due to the electromagnetic field, and when the voltage disappears, the armature in the core goes to its initial state. When powered, a magnetic field appears, causing the armature to retract the return springs. When the car engine starts, the voltage begins to disappear, the spring presses on the armature and it returns to its initial position, the contacts open, the Bendix disengages. If the solenoid relay breaks down and before replacing it, you should first make sure that the problem lies in the starter.

Note. It is necessary to exclude the following malfunctions in the car: the presence of scale, battery discharge, traces of oxidation on the terminals, damage to the wiring, loose contacts. The car may not start for these reasons.

Types of solenoid relays and their manufacturers

Let's briefly touch on the solenoid relays used on VAZ cars. They are divided into four types:

for non-geared starters of VAZ 2101-2107 (“Classic” models);
for non-geared starters of VAZ 2108-21099 models;
for VAZ gear starters of all models;
for AZD starter gearboxes (used in VAZ 2108-21099, 2113-2115 models).

In addition, as mentioned above, they are divided into collapsible and non-collapsible. Older models are collapsible. New and old are interchangeable .

For VAZ cars, solenoid relays are produced by the following companies:

Plant named after A.O. Tarasov (ZiT), Samara, Russian Federation. Relays and starters are produced under the KATEK and KZATE trademarks.
BATE. Borisov Automotive and Tractor Electrical Equipment Plant (Borisov, Belarus).
Kedr Company (Chelyabinsk, Russian Federation);
Dynamo AD, Bulgaria;
“Iskra” A Belarusian-Slovenian enterprise whose production facilities are located in the city of Grodno (Belarus).

When choosing a particular manufacturer, it is necessary to take into account that the highest quality and most common brands are “KATEK” and “KZATE”. Also remember that if an AZD starter is installed on your car, then “native” relays manufactured at the same enterprise are suitable for them. That is, they are not compatible .

Results

The starter retractor relay is a simple device. However, its failure is critical , as it will not allow the engine to start. Even an inexperienced car owner with basic plumbing skills can check and repair the relay. The main thing is to have the appropriate tools at hand. If the relay is not removable, we still advise you to replace it, since, according to statistics, after repairs are completed, its service life will be short. Therefore, if the solenoid relay does not work in your car, buy a similar device and replace it.

Examination

VAZ 2110 retractor starter

To check the functionality of the starter, you will need a battery and two wires:

First the starter is removed;
Using the first wire, the output of the solenoid relay is connected to the positive terminal of the battery;
The second cable is connected to the negative terminal with the starter ground;

Note: if there is a click, this indicates that the Bendix mechanism is working. It is important that the click is sharp and fast. If the sound seems sluggish and drawn out, then something is wrong inside the mechanism, for example, the pin contacts have burned out.

VAZ 2110 does not turn the starter, the retractor clicks

If, after the inspection, there is a suspicion that the starter requires repair, you should immediately go to purchase a new spare part. If the starter is not removable, then the entire solenoid relay must be replaced. If it is collapsible, then:

To repair the solenoid relay, unscrew the screws on the relay housing cover.

Note. In some cases, it is necessary to unsolder the ends of the winding; they can be an obstacle to removing the cover.

After removing the cover, the power contacts are checked; in many cases they cause damage to the device.

Note. If possible, replace old contacts with new ones. If the contact is not badly damaged, the burnt surface is removed using fine-grained sandpaper.

After this, the structure is assembled in the reverse order.

The retractor relay is installed under the hood and is located on the starter. When buying a new one, you need to take the non-working item with you and ask the store for a similar one - in this case, mistakes are excluded. All manufacturers make their own markings on the solenoid relay. The device is secured with three screws.

VAZ 2110 remove starter retractor

Checking with the starter removed using a multimeter

This test of the solenoid relay allows you to very accurately perform internal diagnostics and determine the condition of the windings and contacts. Dismantling the starter, depending on the make of the car, is carried out in various ways. For VAZ 2110, this procedure is carried out from below from the pit. Before unscrewing the fasteners, remove the wires (it is better to mark the terminals so as not to confuse them during assembly); you may need to remove the crankcase protection.

To begin with, voltage is applied from the battery to the body and terminals of the relay; operation is accompanied by a characteristic click and visible movement of the rod. Further checks are carried out using a multimeter, which is switched to resistance measurement mode and the range of 200 Ohms is selected.

First, check the serviceability of the retractor and retention coils. To do this, one of the probes is connected to ground, the second touches the contacts in succession. The device readings are 2 ohms. Deviation of the device readings from the specified value is a sign of a break or short circuit.

To check the power contacts, remove the core from the relay body and remove the return spring, after which the core is inserted back. The core rod is pressed against the table with a certain force and the resistance between the contacts is replaced. The resistance is approximately 1.5 ohms.

Replacement

VAZ 2110 starter retractor

To replace the solenoid relay on a VAZ 2110, you will need the appropriate tools. Before starting work, it is imperative to disconnect the battery mass, which is marked with a minus sign, from the battery. To do this you will need a 10mm wrench. After removing the contact, you need to find the starter. It is located at the bottom of the engine compartment, between the engine block and the cooling system. Only after this can you begin to dismantle the device.

VAZ 2110 starter retractor

Two wires are connected to the solenoid relay; it is necessary to disconnect the red wire that runs from the relay to the male contact.
Unscrew two nuts on the back of the relay; this is done using a “13” wrench.
Using a flathead screwdriver, disconnect the cord from the front of the relay retainer.
After releasing the relay, it must be carefully removed.

Note. When performing this procedure, you need to make sure that the core is inside and the spring located in the relay does not fall out. This is a very complex procedure in the process of replacing the solenoid relay.

To install a new retractor, repeat the steps in reverse order. Due to the fact that we left the old core, the new relay is mounted without it, only with a new spring. So:

Armed with a flat-head screwdriver, you need to screw the wires in front of the relay.
Connect to the wires and tighten the nuts using a “13” wrench.

After installing the relay, you need to tightly tighten the nuts that connect the power wire and are attached to the “male”. That's all, the machine is ready to go. To replace this element yourself, you will need only three tools, a video review and a photo instruction. To perform this procedure with your own hands, you will have to spend about 16 minutes of time and save about 500 rubles in your wallet, which you would have to pay for repairs in car workshops, where the price of these services is constantly rising.

Selecting a part for a VAZ-2110

Often the entire starter assembly is replaced, but we recommend not doing this. The pull-out relay is much cheaper than the entire kit.

The choice of a new relay should be approached with the utmost seriousness, since the quality of the part will determine how long it will serve the owner.

Most VAZ-2110 are equipped with a solenoid relay manufactured by Bosch, with catalog number 2339303293 . The cost of the part is about 2000 rubles.

Analogs

In addition to the proposed version of the original part, there are quite a lot of analogues that can be installed on a car. So, many car enthusiasts do just that. Let's look at what the automotive spare parts market offers the owner of a 2110:

Cargo 131143

How does the VAZ-2110 starter relay work?

When the current stops flowing through the coil, the armature is free in the core. The solenoid relay consists of a magnet with two windings, an armature, contacts and a return spring. The magnet consists of two coils: one retracting, the other holding. The first is connected to the control terminal and the electric motor, the second is connected to the control terminal and goes to the housing.

When the control contact is energized, magnetic induction is induced in the coil, creating a magnetic field that causes the armature to compress the return spring. At the same time, it rotates the bendix, which connects the battery to the starter. The retracting winding is energized “+” when the contacts are closed, the current stops flowing through the coil, but the armature remains inside under the influence of the field of the holding coil.

When the engine starts and the power is turned off, the return spring moves the armature to its original place - the contacts are open, the bendix is disengaged.

How it works

The design of the “ten” starter is such that inside it there is a retractor relay, which is responsible for the rotation of the drive gears. When the gears engage the teeth of the crankshaft flywheel, starting occurs. Therefore, if the retractor does not work, then you will not be able to start the engine.

Plus, when the contacts on the traction winding are closed, the starter motor is supplied with power from the battery. The contacts are washed out, the blocking is activated, due to which the retractor winding is “cut out”.

The retractor is controlled directly from the ignition switch. Plus it plays the role of starter protection. The fact that the relay will require an impressive amount of current leads to gradual wear of the contacts in the contact group.

This can be noticed by the unclear start of the power unit; periodically the starter may not operate or may rotate the engine slowly. You can solve this problem on your own.

How to install the VAZ-2110 starter solenoid relay?

We remove the terminals from the battery, put the gearbox in neutral, otherwise when the starter is turned on, the car may start moving.
We purchase a four-contact relay with open contacts, three wires with “mothers” with which we will connect the relay to the retractor starter and plus to ground, of which: two 25 cm each - on one “mother” at both ends, one with a terminal at one end and a ring for an M8 bolt on the other, also 5 cm with a terminal and a ring for M6.

We connect the relay with the retractor as follows:

Using one nut to ground, we tighten the wires, with the second we secure the relay, plus it will come from the power stud:

Connection diagram

The starter is connected to the on-board network of the VAZ-2110 car according to the standard scheme. It is working and tested, does not require any intervention. The ignition switch has two contacts that close when the key is turned to the extreme position. Now there is no need to talk about the fact that power is supplied to the ECU, fuel pump and other elements of the car. We are talking exclusively about the starter, so only its operation needs to be considered.

So, the contacts closed when the key was turned to the extreme position, and power was supplied to the electromagnetic relay. It is installed under the dashboard. Its switching terminals are supplied with the positive terminal from the battery through a fuse. The voltage is removed from it and supplied to the winding of the traction relay of the VAZ-2110 starter. The result of this is that the armature retracts, moves the bendix and closes the power contacts. The latter are connected as follows: one directly to the battery positive, and the second to the starter power wire.

Replacing the starter relay

Clicking noises when turning the ignition key, but without cranking the starter itself
no reaction at all when trying to start the engine

Of course, there are times when the relay can be repaired, for example, when nickels burn. In this case, you can simply clean them and everything will work again. But in most cases you have to change the retractor completely. Fortunately, the price of this part is not so high, so you won’t have to spend much.

It is worth noting that to perform this repair you will need the following tool:

Socket head 13
Ratchet handle
Phillips blade screwdriver

Of course, it is most convenient to replace the retractor after removing the starter. After this, you must first unscrew the nut securing the wire terminal, as shown in the photo below:

And disconnect it:

Now turn the starter over and unscrew the two bolts securing the solenoid relay:

Now you can remove the relay by moving it to the side:

If the core remains engaged, then you need to disconnect it with a simple movement of your hand:

Now you can replace the solenoid relay, since everything is ready for this. The price of a new part may be about 500 rubles. Installation is carried out in reverse order.

Signs and causes of relay failure

If the relay is broken, the following signs will tell you about it:

when you try to start the engine with the key, it does not start, or starts only after two or three attempts;
There is a buzzing sound after the engine starts. This means that the starter rotates at higher speeds, although it should no longer be.

If at least one of these signs is observed, then this is a reason to be wary. The relay may soon break. There are several reasons why this happens:

one of the windings, or both, were burned or broken at once;
deformation of the return spring inside the mechanism;
a short circuit has occurred inside the part on one of the windings;
The surface area of the contact plates has decreased, or they have completely burned out.

Understanding the reasons why the relay fails, repairs will take less time, because It’s immediately clear where to look for the problem.

VAZ 2110 - replacing the starter retractor relay

The most common reason why the car starter does not work is a malfunction of the solenoid relay. You can drive your car and not suspect anything, but at one fine moment the car will stop starting, you will need to call friends and start it with a push. To be armed and know the features of the starter, today we will tell you how to replace the solenoid relay on a VAZ 2110 with your own hands.

This is interesting: Video on how to assemble a starter on a trimmer

Symptoms of a malfunction can be different, for example, the relay clicks, but the starter itself does not turn, or it happens that when you turn the ignition key there are no signs of life. To quickly troubleshoot a problem, you need to have the following tools available:

- flat screwdriver; - head 8; - ratchet.

Let us remind you that in the previous article we told you how to replace ball joints on a VAZ 2110 with your own hands. Considering the quality of parts today, replacement is required almost every 5-6 months, so I recommend bookmarking the instructions.

Replacing the starter solenoid relay with your own hands

1. You can unscrew and replace the relay without removing the starter from the car, but it is better to do all this with the device removed from the car. When this is done, you need to unscrew the nut securing the terminal to the stud, as is clearly shown in the photo above.

2. Then carefully remove the terminal and move it and the wire a little to the side.

3. Now on the back side of the starter you need to unscrew two bolts using a regular flat-head screwdriver. All this is clearly demonstrated in the picture.

4. Now you can remove the relay without experiencing any difficulties. gently pulling it back. If it does not come off, then you need to lift it slightly so that it disengages from the anchor.

5. If it was removed separately from the spring, then it can be removed later along with the anchor.

How to replace the starter solenoid relay on a VAZ 2107 One of the main causes of starter failure on a VAZ 2107 is the failure of the solenoid relay. The first symptoms of a malfunction are when you hear clicks when you turn the ignition key, but the starter never starts to turn. Today we will look at

Replacing the solenoid relay on a VAZ 2115 The solenoid relay in the VAZ 2115 starter is the most vulnerable point, so when malfunctions occur in the starter, you should immediately pay attention to this detail. Symptoms of a malfunctioning solenoid relay can vary, ranging from:

How to repair a relay with your own hands

Basically, repair work involves dismantling a number of mechanisms. Here it is important to remember to take precautions - do not rush, do everything very carefully, turn off the power to the machine. It is also worth considering carefully whether there is a need to repair the starter retractor relay yourself. In the absence of the necessary skills, abilities and tools, you should entrust everything to the hands of professionals - otherwise you can not only aggravate the breakdown, but also get injured.

At the same time, if you decide to carry out repair work yourself, disconnect the power from the battery. This is the initial step to disassemble the starter, otherwise all the car's wiring may burn out.

Do not rush to dismantle the device; first, wipe all elements from dirt so that dust does not penetrate inside the system. Only after this we begin to unscrew the brush assembly nut. Next we get the contact. Then we proceed to the coupling screws, the task of which is to connect the assembly to the mass.

If everything is done correctly, we will be able to completely remove the relay from the mechanism. Now we proceed to unscrew the nut at the end, as a result of which the part is divided into two parts. This way we gain access to the core, thanks to which we can replace the faulty element, after which we install the mechanism in its place.

We recommend: Polishing and grinding discs

As a final step, it is worth checking the serviceability of the elements. If everything functions as it should, we mount the relay in the vehicle. After completing the repair work, we once again evaluate the performance of the system.

How does the VAZ-2110 starter relay work?

When the engine starts and the power is turned off, the return spring moves the armature to its original place - the contacts are open, the bendix is disengaged.

How to install the VAZ-2110 starter solenoid relay?

We remove the terminals from the battery, put the gearbox in neutral, otherwise when the starter is turned on, the car may start moving.
We purchase a four-contact relay with open contacts, three wires with “mothers” with which we will connect the relay to the retractor starter and plus to ground, of which: two 25 cm each - on one “mother” at both ends, one with a terminal at one end and a ring for an M8 bolt on the other, also 5 cm with a terminal and a ring for M6.

We connect the relay with the retractor as follows:

DIY VAZ starter repair

It is important to know!

Every motorist should have a universal device for removing scratches on a car of any color. The effect is visible within 10 minutes, and the action of RENUMAX will pleasantly surprise you with its simplicity and effectiveness. Read more >>>

The service manual contains detailed instructions for replacing the starter, and you will also find a diagram and design of the starter in it). But as a rule, any similar process is not without difficulties, so let’s figure out how to repair a starter using a specific example:

Removing the starter retaining ring

To remove it, I had to pry it off with a flat screwdriver. After replacing the starter Bendix, I had difficulty reassembling the rings in the reverse position, but something turned out to be wrong. It turned out that the restrictive ring has a slot for the retaining ring and should be put on on the opposite side of the bendix.

Repair of starter retractor relay

The starter solenoid relay (the little thing to which the wires attach, also called the traction relay). The principle of its operation is as follows: 12v is supplied from the ignition switch to the coils in a metal case. They retract the armature of the retractor relay (a metal sinker with its end hooked to the tail of the bendix). With one end he drives out the bendix, with the other he presses the lever inside the relay, which closes the “+” contact coming from the battery. The plus is transferred to the brushes that make the armature spin. The gears transmit torque to the extended bendix, thus the flywheel rotates.

When removed carefully, you can easily break it by pulling the contacts from the winding. After unscrewing, you need to heat the contacts with a soldering iron and remove the plastic from the metal case. There is no particular point in disassembling it. You can't get into the coils; they seem to be filled with plastic. Therefore, in this case, it is recommended to strip the copper contacts from the lever, and the contacts from the bolts. You can also check with a tester for the presence of contacts.

Checking the starter solenoid relay:

Usually “+” is applied to the flat contact from the ignition switch, and “-” to the housing.
Alternatively, it’s different: “+” is a flat contact and minus is on the bolt to the starter (more precisely, on the brushes installed in a larger housing). There should be a click (don't forget to put the anchor inside).

Thus, by checking it is possible to determine the cause of the starter malfunction. For example, poor contact can be corrected by placing tin on the washer holding the contact bolt.

The price of the starter retractor relay is about 350 rubles.

Disassembling the stator with armature

When it's the starter

If after these steps the starter continues to be silent, it means it is broken. To repair it, you need to disassemble the solenoid relay. But how to do this if the mechanism itself is not intended for disassembly? In an old-style relay, you need to unscrew one or two screws and unsolder the wiring that goes inside the device.

Modern devices are non-separable, and in order to open the back panel, you will have to flare the metal body of the mechanism. Flaring can be done with a large screwdriver or pliers. After this you need to remove the cover. To repair, clean the burnt contact plate and the surfaces of the bolts from soot to a shine. The better you clean it, the longer the relay will last you.

Of course, it would be wiser and safer to go to the nearest service station, but for a number of reasons, drivers sometimes repair the car themselves. Saving money and time requires preliminary preparation and certain knowledge in machine repair.
