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.
Standard option
Which generator is better to install on VAZ 2106 and 2107? The question is quite complicated. It needs to be considered starting with the most common option. After all, any manufacturer will say that it is the standard version that should be installed on the car. Let's look at the features of the standard version G221.
In this type of relay generator, the regulator is installed separately from the brush assembly. This makes it easier to troubleshoot some problems to some extent. The advantage is the ease of installation, there is no need to adjust the wiring for connection, everything is done according to the standard scheme. But such a generator is low-power; it produces a charge of a maximum of 42 A, which is not enough for most modern batteries.
From all this, we can conclude that a standard generator is certainly good. But, if you have additional devices, it is not very profitable to use it. It is best to choose a more powerful option.
This generator is intended for use on Niva cars. It is capable of delivering 50 A of current, which is quite enough for full-fledged electrical work. It differs from a standard “six” generator in the presence of a built-in regulator relay. Here it is assembled into one unit with brushes. Therefore, to install it on a VAZ 2106, you just need to make some minor modifications. This electric machine is installed on 2107 without any special interference or modifications.
There are several ways to refine such a generator. The easiest way would be to install brushes from the G221 generator. They fit perfectly in place of the relay assembled with the brush assembly. No modifications are required, this allows you to install such a generator, even for people without special skills. It is possible to install the G222 with a standard regulator, but to do this, you will have to redo the generator connection diagram. Otherwise, nothing will work out.
Main details
To understand where to look, you need to remember the main components that make up the generator. This:
- pulley;
- front bearing;
- rotor impeller;
- stator winding;
- magnetic circuit;
- rotor;
- rear bearing;
- “chocolate” (relay-regulator);
- diode bridge.
Most often, the brushes that are part of the relay-regulator unit wear out. Bearing wear is also common. You should also expect breakdowns of the diode bridge and the generator belt (which drives the pulley). Another part that requires periodic replacement is slip rings. They are located on the rotor and are in contact with the brushes.
To increase service life, you should regularly lubricate the mechanical components of the device (especially bearings), measure the voltage, the battery charge level and its condition, and tighten the fasteners. If you suspect any kind of breakdown, you must immediately begin repairs, otherwise there is a risk of failure of any connected device and component. If the car has an injector and an ECU, then electricity is not something to joke about. And the most ordinary care and prevention will reduce the likelihood of breakdown to almost nothing.
Generator 2108
This device is often installed on both 2106 and 2107. This is due to its greater efficiency; it produces a charging current of 55 A, which is quite enough for most motorists. But, if your car has significantly more equipment, then it is better to choose something more powerful.
These generators are identical in terms of mounting, so there will be no problems with the installation itself. Of course, if you remember to remove the terminal from the battery. The fun starts when you connect. The whole point is that 4 wires are attached to the original device. There are only 3 for the “eight” one. This is due to the built-in voltage relay. To obtain a normal result, you need to insulate the black wire, and connect the rest as usual. When the generator is running, the light indicating the discharge will be on. This is a normal phenomenon with such a connection. Accordingly, it should go out when there is no charging.
Types of breakdowns
What problems occur if the generator is not working properly?
- Extraneous noise appears.
- Complete lack of battery charging while the engine is running.
- Overheating and failure of the same battery.
- Damage to any or all energy consumers, including the injector.
- Increased or decreased voltage in the electrical system. The standard voltage is 13.6-14.5 V.
- Mechanical or electrical damage to the elements of the generator itself.
Obviously, this node requires special attention.
The indicator flashes
If in the previous case there is often not enough charging, here, on the contrary, there is a recharge. The regulator and brush assembly need to be replaced.
The noise may be caused by worn bearings, excessive tension or loosening of the belt. You need to make sure that all fasteners are secure and the gaskets are intact. Less commonly, the cause of this is a malfunction of the rotor or stator. And, again, the same generator brushes can make the most unpleasant sounds. In this case, they are changed or wiped with gasoline.
Generator from PRIOR to CLASSIC [PVS] [FullHD]
A short description or idea for those looking for good pay. Questions about subscribing to the channel.
There are several ways to improve such a generator. The easiest way is to install brushes from the G221 generator. They fit perfectly into the location of the relay and brush assembly. No modifications are required, this allows the installation of such a generator even for people without special skills. It is possible to install the G222 with a standard controller, but you will have to repeat the generator wiring diagram. Otherwise nothing will work.
This device is often installed on 2106 and 2107. This is due to its higher efficiency; it produces a charging current of 55 A, which is quite enough for most motorists. But, if your machine has a lot more equipment, it is better to choose something more powerful.
From an installation point of view, these generators are the same, so there are no problems with the installation itself. Of course, if you remember to remove the terminal from the battery. The fun starts when you connect. The fact is that there are 4 wires wound on a wired device. There are only three in the eight. This is due to the built-in voltage relay. To get a normal result, you need to isolate the black wire and connect the rest as usual. When the generator is running, the discharge indicator lights up. This is normal with such a connection. Accordingly, it should happen when there is no charge.
In principle, it's already a good ride, but if you want to do it right, you'll have to make a few more improvements. We take out the old relay and replace it with a regular power relay. Now the light only comes on when the engine starts and at low speeds, which is quite acceptable.
When installing on a VAZ 2107, all you need to do is add a power relay.
Lovers of various accessories need an even stronger “gene”. They may recommend installing a VAZ 2107i device. This unit produces 80 amps, which is sufficient for any electrical systems the owner adds. When purchasing such a generator, keep in mind that there are several varieties. Only model 2107-3701010 is suitable for installation on the VAZ 2106; Any of the generators in this series can be installed on a “seven” carburetor.
It is advisable to modify the device for installation on the “six”. To do this, the relay controller was replaced with a similar one from G222. The connection is very similar to working with an "eight-dimensional" generator.
Conclusion. Initially, weak generators were installed in the sixties and sevens. But as technology developed, their power did not become sufficient to ensure proper power supply to the car. Therefore, the question is which generator is better to install on the VAZ 2106 and 2107 . Luckily, there are plenty to choose from. The next generation devices are ideal for the old Lada after a little modification.
Constantly lit indicator (even when the ignition is turned off)
To eliminate the problem, you will need to replace the diode bridge with a new one. The reason for this was a short circuit on it. You can try to repair it, but this requires knowledge. Replacement cost is low.
Generator 2107-3701010
For lovers of various additional equipment, an even stronger “gene” is required. They can recommend installing a device from a VAZ 2107i. This unit produces 80 amps, which is sufficient to operate any electrical systems added by the owner. When purchasing such a generator, keep in mind that there are several varieties. For installation on a VAZ 2106, only model 2107-3701010 is suitable; any generators of this series can be installed on carburetor “sevens”.
It is advisable to modify the device for installation on the “six”. To do this, the relay regulator is replaced with a similar one from G222. The connection is completely similar to working with a figure-of-eight generator.
Conclusion
. Initially, rather weak generators were installed on the “sixes” and “sevens”. But, in the process of technology development, their power was no longer enough to provide adequate power to the car. So the question arose, which generator is better to install on the VAZ 2106 and 2107. Fortunately, there is plenty to choose from. The next generations of devices are perfect for old Zhiguli cars after a little modification.
So here the problem of low voltage is tormented. The generator is old and scary. Now we eat more and during the day we need to turn on the light. So I thought about replacing it with a more powerful one. Please advise which one is more rational to put in check.

Difference between carburetor and injection systems
Many car owners independently replaced the carburetor with an injector , and some bought a car with an already updated system. One thing is certain – this is a step forward. But this means changing the operation of many nodes. How are things going with the generator, its operation and repairs?
There are differences, albeit minor ones. The injector assumes the presence of an ECU on board the VAZ 21074. And this is another consumer of electricity. Additional wiring is connected to the generator to provide power to the elements of the electronic control system. There are no more changes.
Possible causes of malfunctions
There are several common reasons that require the driver to look under the hood of the “iron horse”:
- partial or complete combustion of the VAZ 2107 winding;
- cases of interturn short circuit;
- physical wear of parts;
- external physical influence;
- mechanical damage.
Inexperienced drivers of the VAZ 2108 or earlier modifications need to remember one nuance. When choosing lighting fixtures, you need to take into account their power. For example, if you decide to install fog lights, the power of which is 40-50 W each, you should look at the technical description of the VAZ 2106 or 07. Their installation is allowed only if the vehicle’s generator produces more than 55 A of current.
Failure to comply with this rule leads to dire consequences. The increased load of the VAZ generator leads to its rapid wear. The power of the unit gradually decreases, which is mistakenly perceived as a minor breakdown. That is why the total power of all voltage consumers should not exceed the maximum current level of VAZ 2107, 08 or 06.
Purpose
The generator was installed for a reason. Without it, the car cannot operate. It contains the following functions:
- generating electricity;
- converting current from alternating to direct;
- battery charging;
- power supply of devices, sensors, any components requiring electricity;
- power supply for auxiliary devices (radio tape recorder, fan, etc.).
Voltage drops
This is best seen at night. If the headlights burn unevenly and constantly change light intensity, then the voltage regulator needs to be replaced.

Devices and sensors do not work
To do this, you will need to check all wiring and contacts. Often the cause of such an incident is the fuse box. It is necessary to check the voltage in all areas to determine the location of the fault. If the cause is the generator, then you need to check the belt tension and the stability of the pulley. Next, the “chocolate”, brushes, and diode bridge must be checked.
Options for replacing a broken unit
The main thing to remember is that to replace a broken generator, it is forbidden to take the first one you come across. Failure to comply with this rule will lead to lengthy and expensive repairs of the VAZ 2107 or other modifications. The most common modification is G-221. To carry out a technically correct replacement, it is necessary to study the following manufacturer’s recommendations:
- Replacing a VAZ generator is possible using a unit from modification 2105. The maximum current level is 55 A, which is suitable for cars with a small number of consumers. Replacement does not imply modifications or modifications.
After the car owner decides on the power, it is necessary to install the device correctly. Car mechanics recommend exercising extreme caution. Poor installation of the generator leads to many problems during subsequent operation.
Types of breakdowns
What problems occur if the generator is not working properly?
- Extraneous noise appears.
- Complete lack of battery charging while the engine is running.
- Overheating and failure of the same battery.
- Damage to any or all energy consumers, including the injector .
- Increased or decreased voltage in the electrical system. The standard voltage is 13.6-14.5 V.
- Mechanical or electrical damage to the elements of the generator itself.
Obviously, this node requires special attention.

Generating Device Replacement Procedure
Before starting work, check the serviceability of the regulator relay. It is advisable to choose a model with the highest possible temperature compensation. This characteristic allows models 2106-2107 to operate at high speeds without failure. This indicator should be studied especially carefully if the VAZ 2106 or later modifications are used in areas with a hot climate.
Removing a broken device and installing a new one does not cause problems, thanks to the clear mounting method.
Difficulties arise at the stage when you need to connect a new VAZ generator. To begin with, the wires coming from the relay regulator are disconnected and subsequently insulated. Further connection of the VAZ 2108 generator is carried out as follows.
The wires, formed in the form of a ring terminal, are connected to the old place in the VAZ 2108. It is imperative to insulate the gray wire, which is not connected anywhere. Completes the installation procedure by connecting the yellow wire to the terminal. If the car owner was unable to find a device with the required power, then a model from a VAZ 2108 to a VAZ 2106 can be installed, provided that the total power of consumers is taken into account.
Careful attitude and regular preventive inspections will ensure long-term reliable operation of the machine. Even with a slight drop in speed or problems when starting the engine, there is a reason to look under the hood. The faster this is done, the less likely it is that the problem will spread further.
On-board network elements
The generator is an important part of the electrical system. This is the vehicle's main source of voltage. The generator converts the mechanical energy of the engine into electrical potential.
The stability of the on-board network voltage guarantees trouble-free operation of all consumers. The normal voltage level depends on the following elements:
- Generator.
- Battery.
- Relay-voltage regulator.
The electrical circuit is one whole. Failure of wiring or a short circuit can lead to failure of the entire system. The generator does not work - the battery charging current disappears. The battery is dead - you can't start the car.
The serviceability test can be carried out independently and at home. Typically, such a procedure does not involve dismantling devices on a Zhiguli-2105, 2107 car. It is necessary to have a tester that measures voltage, winding resistance, and the serviceability of diodes.
There are mechanical and electrical components of the unit. It doesn’t matter whether there is a carburetor or an injection system, the generator is checked in two directions. The following mechanical parts are subject to assessment:
- body elements;
- V-belt;
- pulley;
- bearing units;
- brush block;
- mounting bolts.
Completion
The most typical and common breakdowns were presented. For correct diagnosis in serious cases, special stands are needed, which are present in many workshops. It should be noted that sometimes the cost of such repairs can be equal to or even exceed the price of a new generator. Therefore, repair is not always the answer.
From the text it becomes clear that there are no significant differences between the injection VAZ 2107 and the earlier carburetor version. The same applies to the modification of the VAZ 21074 and all others.
Generator manufacturers claim that the generator is designed for 200-250 thousand kilometers. After passing the barrier of 100-150 thousand, it is necessary to conduct a thorough inspection and lubricate all mechanical connections.

How to change the regulator relay
If necessary, the generator relay 2107 is replaced with a new one if the diode bridge is working properly and the voltage is significantly higher than required or lower than normal.
You can replace the relay-regulator either by removing the generator or carry out repairs without removing it. To do this, of course, you need to know how to attach the relay, since you will have to work almost by touch. The only tool you need is a short screwdriver. The repair is carried out from above, under the hood.

Replacing the brushes of the VAZ 2107 generator is not carried out separately. The brushes are changed together with the voltage regulator, although everything can be done if desired.
How to properly tension the belt on the generator
When installing a generator on a VAZ 2107 yourself, the most difficult moment is considered to be proper belt tension. After all, it is through the belt that the generator mechanism will be launched, therefore, any errors and miscalculations when tensioning the rubber product will affect the performance of the car.
The belt tension is performed as follows:
- Place the new generator
- Tighten the fixing nuts only halfway, without over-tightening.
- Use a pry bar to install into the gap formed between the generator wall and the pump. Secure the mount in this position.
- Place the new belt on the alternator pulley.
- Hold the pry bar and begin tensioning the belt.
- Tighten the fixing nut in the upper part of the mounting of the generator unit housing.
- Afterwards, carry out a preliminary diagnosis of the degree of tension - the rubber product should not sag downward much.
- Tighten the lower stud nut until it ends without overtightening.
Next, the quality of the belt tension is checked. Using two fingers, press firmly on the free part of the belt and measure the existing deflection. Normal sagging should not be more than 1.5 centimeters.
The service life of a typical belt for a VAZ 2107 generator is usually 80 thousand kilometers. However, it is recommended to change the belt drive earlier if the generator set is being replaced.
Thus, the generator on the “seven” can be replaced with your own hands, but you must adhere to strict rules and observe safety precautions. If you have problems with the operation of the motor after replacing the device yourself, it is better to contact a professional.
A car generator is a device that provides the on-board network with a constant electric current of up to 80 Amperes . In terms of its design features, the unit has much in common with an electric motor. Inside the housing there are two windings, as well as covers on the sides, equipped with bearings.
Technologies do not stand still. Over the years, the generator circuit has been improved, its design has been optimized, and its output characteristics have improved. Modern models are capable of delivering up to 80 Amperes or more, which indicates an increase in the power of the device.
Connection diagram
The connection diagram for the VAZ 2107 generator is shown in
On the generator connection diagram 37.3701: 1 – battery, 2,3,5 – rectifier diodes, 4 – generator assembly, 6 – stator winding, 7 – charge relay, 8 – rotor winding, 9 – capacitor, 10 – fuses, 11 - indicator lamp, 12 - voltage meter, 13 - relay, 14 - lock.
If the output parameters are monitored and they do not correspond to normal values, a decision is made to dismantle and repair the generator
How does the injection system work on the "seven"?
How much fuel is supplied through the injectors to the cylinders is controlled using an electrical impulse from the ECU. The block calculates the amount of fuel the engine needs and also determines how long the pulse will be.
When the crankshaft begins to rotate, the very first impulse from the idle speed sensor causes the ECU to turn on all the injectors. The very first injection takes place every time you start. How long the pulse lasts depends on the temperature.
When the driver turns on the ignition, the fuel pump relay is activated and creates pressure in the fuel line. Next, the computer checks the temperature and calculates how much air and fuel is needed to create the mixture, and then delivers it to the engine. VAZ 2107 injector , by the way, is more economical than its carburetor counterparts. This is achieved through more accurate dosage of fuel.
