Video “How to repair a Priora generator with your own hands?”

Detailed information and recommendations regarding the repair of the generator unit from the Lada Priora car are given in the video below (the author of the video is the Do-It-Yourself channel).

If the generator is seriously damaged, it does not have to be repaired, but completely replaced. Parts necessary for repair may be missing, or the breakdown may not be repairable at all. Meanwhile, the on-board voltage and the quality of battery charging depend on the good operation of the power unit. It's a shame when, despite a good motor, electrical equipment does not work properly.

And if we are talking about VAZ cars, then sometimes a replacement is in demand due to the lack of power of standard devices. Modern automakers offer many additional devices that increase the level of comfort when traveling, but they also consume a large amount of electricity, and old devices cannot cope, so they have to be replaced with more powerful ones.

Many people are interested: which generator to buy if they have a VAZ? Here you need to consider them separately by model, so before you go shopping, read the recommendations of specialists and compare them with your wishes and capabilities.

Basic problems

There are several main problems specific to a generator. If you study them, it will be quite possible to carry out repairs even on your own.

We will list them and also tell you about the necessary additional actions to eliminate them.

Your actions

To fix this problem, simply replace the old fuse with a new one. But be sure to determine the reason why the problem arose

The circuit supplying the devices has broken

In this situation, be sure to make sure that the neutral wire is connected securely to the other contacts

Having problems with the ignition switch

Check if the ignition switch board is working

The control lamp has failed

Just change the device to a new one if the lamp just burns out

You will have to change the brushes themselves, as well as their holders. Check the contacts for oxidation. They can be treated with WD40 or cleaned with gasoline

Voltage regulator does not work

This unit must be replaced. It is impossible to repair it

The alternator belt is damaged or faulty

You can try to adjust the belt tension if this is the problem. If the unit is damaged, it must be completely replaced.

Only its complete replacement will help here.

Such breakdowns occur quite often, so they cannot be ignored at the first sign. Having understood the structure of the generator, solving problems with its malfunction becomes much easier.

Where is he located

Before removing the generator, you need to at least figure out where this device is located.

This is exactly where the desired element is located.

Functionality check

If the generator does not work correctly, the consequences can be unpredictable. If the charge coming from the device is low, the battery will quickly run out and your VAZ 2114 will simply stall. High voltage is even more dangerous because it damages the entire electrical circuit of the car.

The power indicators of the generator can be measured using a tester.

Turn the ignition on and make sure all the lights on the dashboard come on. After this, start the power unit.
If the battery icon lights up on the panel or blinks dimly, there is damage to the alternator circuit.
Warm up the engine to approximately 90 degrees, then turn on all volatile devices.
Connect the tester directly to the battery. The second person at this moment will press the gas pedal and keep the speed in the region of 3.2-2.5 thousand revolutions.
When the tester reads 13V, the generator is working properly.
Now turn off all power consumers and take measurements again. The revolutions are kept the same. If the generator is working properly, the tester readings will be 14.7V.
At the same time, we recommend paying attention to the sounds that come from the generator. If there is a hum, there is a high probability of bearing wear, which should be replaced.

Stories from our readers

“Fucking basin. "

Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.

HUCO-130512
Febi-17202
Bosch-1197311028
Hella-5DR 004 242-061
Beru-0 190 005 004

The modification process begins with the removal of the relay regulator. Required:

Standard voltage regulator (160r.)
Voltage regulator from a foreign car for 14.5V.

The box contains the catalog code for the spare part. Price 420 rubles, a cheaper brand will cost 220 rubles. In general, any company will do, the main thing is that the shape is identical to ours.

We separate the tablet from the standard voltage regulator; this is done simply and does not require demonstrations. As a result, we just get a bare body with brushes. We separate the 14.5V tablet from the LV of the foreign car. Be careful not to damage the tablet. Now we are trying to combine the tablet of a foreign car and our body with brushes.

The photo shows a dismantled tablet with a foreign car's pH and a body with brushes.
Because it is a little larger, it is not that easy to install. This is what a combined foreign-made 14.5V tablet looks like with our PH housing.
And a standard pH and a 14.5V tablet assembled and ready for use.

Next, we solder the leads of the foreign tablet to our RN body. The terminals will have to be slightly bent to fit the outputs of the LV housing. We place the tablet on the standard PH body and screw the tablet to the body with bolts.

Next, solder the terminals of the tablet. We clamp the lead at the very base to dissipate heat and place the solder so that the lead of the tablet is completely covered with tin. We cover the nuts to prevent self-loosening due to vibration. We get a standard pH and a tablet from a foreign car at 14.5V. Now all that remains is to install a reinforced generator on the car.

As a result, our high-power generator showed:

On a warm car, the voltage at the terminals is 14.4V
With an average network load, the voltage was 14.2-14.3V
When all devices were turned on, the generator voltage dropped to 14-14.1V and remained the same when the internal combustion engine warmed up to 90C o.

Another way to increase the car's network voltage is to install a diode in the generator or other voltage regulator. If after such modifications the generator still cannot cope, then think about how to put the electrical equipment in the car in order.

The generator is responsible for the functioning of the complex of accounting programs for the electricity of the VAZ 2114 car. This system of dispersing electricity has its shortcomings, both purely personal and more widespread.

The fuse has blown. To fix this problem, you just need to change the fuse. But first you need to find out the reason.
The circuit supplying the devices is broken. Be sure to check the connection of the neutral wire with other contacts.
Damage to the ignition switch. Make sure the ignition switch circuit board is in good condition.
Indicator lamp malfunction.
Brush malfunction. To eliminate the malfunction, you need to change the brush holder and the brushes themselves, just clean the oxidized contact rings in the presence of gasoline, or treat them with WD-40.
Malfunction in the voltage regulator.
Damage, as it is also called, is a malfunction of the alternator belt.
The bearing is faulty or broken.

The described malfunctions often occur, if you ignore them and do not make the necessary repairs in time, the generator will be completely destroyed, and then it will have to be completely replaced. Which in monetary terms is even more costly than repairing small problems.

Replacement

Now let’s talk directly about how we can remove our ill-fated generator. We recommend that you study the relevant videos in order to better understand the nuances of dismantling.

If you follow the instructions, there should be no problems with removal and replacement.

Find a place where there is a lift or pit. That is, an ordinary garage may be quite suitable.
Remove the protection from the power unit.
Loosen the drive belt tension roller slightly.
The upper bolt responsible for fastening the generator should be unscrewed.
By analogy, we work with the lower fastening element.
Next, be sure to disconnect the air conditioning compressor fasteners.
Then remove the drive belt.
Now you can remove the generator from its seat and move it slightly to the right in relation to the battery.
Remove the bolt on top of the air conditioning compressor. Remove the compressor and hang it up. Don’t worry, the tubes used are quite reliable, so they can easily handle the weight.
Remove all bolts from your generator holder.
When you disconnect the terminal, calmly pull down the generator along with the holders.
Reinstallation of the new device is carried out in strictly reverse order. In this case, adjusting the drive belt is a must.

It is not difficult to remove and replace such a unit yourself. But you will definitely need certain skills and preliminary study of the instructions. Use only high quality and efficient replacement parts to ensure that your generator does not cause problems in the future.

A generator in a car is a device that ensures stable operation of the vehicle’s on-board electrical network, in particular the VAZ-2114. This system of generating and supplying electricity has its advantages and disadvantages. In this article we will look at the main malfunctions of this unit, as well as the process of replacing the part with a new one.

Where is the best place to buy?

If the owner of a VAZ 2114 car needs a working generator, then he has a lot of options for places where he can purchase the unit. The choice depends on your financial situation and availability of free time.

If the budget is limited, non-original or used devices are also suitable. You can buy them at the car market or through an advertisement from VAZ 2114 owners. But here no one issues a warranty card, and it is impossible to check the serviceability of the unit. It is not recommended to go to disassembly points: they usually sell faulty devices.

Basic device malfunctions

On a VAZ-2114, the generator may fail for the following reasons:

The fuse has blown. To solve the problem, it is enough to install a new element, having first determined why it failed.
A break in the circuits that go to the devices. Be sure to make sure that the neutral conductor is connected to other contacts.
Malfunction of the ignition switch.
The control lamp has burned out.
Problems with generator brushes. To fix the damage, you need to install a new brush holder and brushes. Additionally, clean the slip rings, which are probably already oxidized, using WD-40.
Damage to the voltage regulator.
Problems with the belt.
The bearing has failed.

The above breakdowns are quite common and if the problem is not solved in time, the generator may fail and will have to be completely replaced. In terms of costs, the car owner will lose much more money compared to repairing minor faults.

If you need to replace a part, you shouldn't do it yourself unless you have the proper experience in car repairs. In this case, it is better to seek help from a service station.

What is this?

A self-generator is understood as a unit that converts mechanical energy into electrical energy. The device is designed to power electrical equipment. For example, thanks to the generator, the wipers, battery, headlights, and dimensions work. If such a unit comes out of a standstill, the motorist notices immediately.

Signs of a faulty generator:

Dimming of headlights.
Complete and sudden battery discharge.
Spontaneous battery recharging.
Deterioration in headlight performance as the speed increases.
Problems with the wipers.

Location of the generator on the VAZ-2114

The device we need is located under the hood of the car to the left of the internal combustion engine.
If you look closely, you can see it in the area next to the front right headlight of the car relative to the interior. First of all, you need to check the condition of the generator, and then only make a decision about the need to replace it.

Unstable operation of the device can have various consequences. If there is insufficient charge at the output, you should expect the battery to discharge quickly, and then the car will simply stall.

Replacing brushes

During regular maintenance, few people pay attention to minor generator malfunctions. Subsequently worn brushes are always a surprise. However, you should not rush to replace these parts. Initially, you need to determine why this happened, and only then disassemble the case.

The brush replacement process is as follows:

Disconnect the wires from the generator.
Remove the cap from the wires going to +, unscrew the nut that secures it, and remove it from the block.
Remove the plastic casing by first releasing the clips.
Disconnect the voltage regulator clamp and do not forget to disconnect the wire block.
Replace the brushes and reassemble in reverse order.

Please note that you need to check the wear of the brushes by the degree of wear of the length of the rod, the value of which can be less than 0.5 millimeters. If the length of the brushes is normal, then the reason for the lack of charge is a faulty voltage regulator.

How to check the generator yourself

How to check a VAZ generator using the example of model 2109. Generator type 94.3701 alternating current, three-phase, with a built-in rectifier unit and an electronic voltage regulator, right-hand rotation.

Generator connection diagram . The voltage to excite the generator when the ignition is turned on is supplied to terminal “D+” of the regulator (terminal “D” of the generator) through indicator lamp 4 located in the instrument cluster. After starting the engine, the excitation winding is powered by three additional diodes installed on the generator rectifier block. The operation of the generator is controlled by a warning lamp in the instrument cluster. When the ignition is turned on, the lamp should be on, and after starting the engine, it should go out if the generator is working. If the lamp is brightly lit or glows half-lit, it indicates a malfunction.

The “minus” of the battery should always be connected to ground, and the “plus” should always be connected to the “B+” terminal of the generator. Failure to turn the battery back on will immediately cause increased current through the generator valves and damage them.

It is not allowed to operate the generator with the battery disconnected. This will cause short-term overvoltages to occur at the “B+” terminal of the generator, which can damage the generator voltage regulator and electronic devices in the vehicle’s on-board network.

Which generator to install

Most car enthusiasts strive to install a part with more power than the standard device recommended by the manufacturer. In this case, the most suitable options would be the Priora or Kalina models. The power of such devices is 115A, while the factory equivalent is only 80A.

However, if you install another generator, you will need to install a different pulley. This procedure is simple and does not require large financial expenditures.

Experienced drivers recommend installing an Eldix generator on the VAZ-2114, the power of which is the same 115 A. But such a device has a significant drawback - it is difficult to find spare parts for repairs.

Functions and connection diagram of the generator

The generator, like all other car parts related to movement, plays a certain functional role. And performs the following functions:

charging the battery;
replenishment of the starter at the moment the engine starts.

Proper and early care of the generator will preserve the functionality of not only the generator itself, but also the battery. This is due to the fact that with a constantly reduced charging voltage, the power source is discharged, as a result of which this will lead to degradation of the storage plates and their further premature destruction. And this, in turn, will lead to an urgent replacement of the battery, the cost of which is sometimes more expensive than the generator.

To deal with possible generator malfunctions, you need to have a good understanding of its structure and connection diagram.

Connection diagram for the VAZ 2114 generator

Modern automobile generators have 3 windings, wound in such a way that an alternating voltage source is obtained. The stator windings act as magnets, and they are powered by a constant voltage from the battery. A magnetic field is formed in which a rotor rotates with a leaf-type magnetic core and a winding from which voltage is removed through slip rings and graphite brushes, with a rating of more than 18 V and a current of 60 to 120 A, depending on its power and number of revolutions. But since the battery voltage should not exceed 14.7 V, a rectifier unit and a stabilizer are used. They are installed on the generator itself, because based on the diagram, it is clear that the wires go directly to the battery and to the starter relay.

Sequence of replacing the generator on a VAZ-2114

To replace, follow these steps:

Place the machine on a pit or lift it with a lift.
Remove the engine protection.
Next you need to loosen the tension roller for the drive belt.
Unscrew the top bolt that secures the generator.
Remove the bottom bolt.
Disconnect the air conditioning compressor retaining fasteners.
The drive belt is removed and the generator can be removed from its seats by moving the device closer to the battery.
Next, unscrew the top bolt that secures the air conditioning compressor.
Now you can completely remove the compressor and hang it on its own tubes. The pipes are quite strong, so they can easily support the weight of the block.
In this step, unscrew the generator holder bolts.
Disconnect the terminals and the generator, disconnect the holders that can be pulled down.
Installation of the new part occurs in the reverse order, followed by adjusting the belt.

To summarize the article, we note that we told you about the main malfunctions of the generator on the VAZ-2114, and also examined the process of replacing the device. If you have never encountered this kind of repair work, then the best solution would be to contact a service station.
