Technical characteristics of generators VAZ 2108, 2109, 21099

The generator of VAZ 2108, 21081, 21083, 2109, 21091, 21093, 21099 cars is a synchronous, three-phase electric machine, alternating current with electromagnetic excitation.
It has a built-in rectifier (diode bridge) based on silicon diodes and an electronic voltage regulator. In addition, there is a rotor - the rotating part of the generator and a stator - the stationary part. The rotor is driven by a belt from a pulley on the engine crankshaft. On VAZ engines 2108, 21081, 21083 there is a V-belt, on 2111 there is a poly-V belt. A number of cars were equipped with generators made in Bulgaria, Slovenia, and Germany. Their characteristics are similar to domestic generators, but they may differ slightly in design.

A 37.3701 generator is installed on VAZ carburetor engines , and a 9402.3701 generator is . Both generators are similar in design and characteristics, the only differences are in the amount of current supplied (9402.3701 is more powerful).

Technical characteristics of generator 37.3701

— The amount of current supplied (at 6000 rpm -1 and voltage 13 V) – 55 A

— Voltage value – 13.6 – 14.6 V

— The direction of rotation of the rotor is right

— Maximum rotor speed – 13000 rpm -1

— Gear ratio engine/generator 1/2.04

Technical characteristics of the generator 9402.3701

— The amount of current supplied (at 6000 rpm -1 and voltage 13 V) – 80 A

— Voltage value – 13.2 – 14.7 V

— The direction of rotation of the rotor is right

Notes and additions

A normally working, serviceable generator of VAZ 2108, 2109, 21099 cars and their modifications produces a voltage in the range of 13.6 V - 14.6 V. This can be visually tracked using a voltmeter on the instrument panel, or it is better to measure the voltage with a voltmeter (multimeter, autotester...). Based on this, generator malfunctions come down to just two problems:

- the generator does not provide charging current at all , or provides it in a small volume (the voltage is low - the voltmeter needle is in the red zone or close to it);

— the generator produces too much charging current (the voltage is higher than normal, the voltmeter needle points too far to the right).

In the first case, the battery is undercharged and, after some time, starting the engine will be problematic. In the second case, the battery is overcharged and, as a result, its electrolyte boils away (the battery “boils”), the plates fall off, and then the final failure occurs.

It is advisable to have at least the simplest tester in order to diagnose generator malfunctions with a high degree of probability. In addition, based on the instrument readings, you can also draw certain conclusions about the performance of the generator set.

Several articles on our website provide the most common malfunctions of VAZ 2108, 2109, 21099 car generators, recommendations for diagnosing and eliminating them.

In addition, articles on the design and technical data of generators for VAZ 2108, 2109, 21099 cars, their electrical circuits and connection diagrams have been added. We hope that all this will help many car enthusiasts in independently solving problems that arise when operating their cars.

car generator VAZ 2108, VAZ 2109, VAZ 21099 - design features of the generator

On carburetor engines and an engine with a fuel injection system, model VAZ 21083-20, a generator of type 37.3701 is installed, and on engines of the VAZ 2111 model, which are equipped with some VAZ 2108, VAZ 2109, VAZ 21099 cars, a generator of type 94.3701 is installed. Both generators are alternating current, three-phase, with a built-in rectifier unit and with an electronic voltage regulator, right-hand rotation (on the drive side). The rotor of generator 37.3701 is driven by a V-belt, and generator 94.3701 by a poly-V-belt from the engine crankshaft pulley (on some VAZ 2111 engines - from a damper). On some VAZ 2108, VAZ 2109, VAZ 21099 cars, an AAK-5102 generator made in Slovenia can be installed. In terms of its characteristics and installation dimensions, this generator is interchangeable with the 94.3701 generator, but has some differences in the design of components and parts.

Technical characteristics of generators

Stator 23 (12) (Fig. 9.6 and 9.7) and covers 1 (10) and 15 (11) are tightened with four bolts. The generator rotor shaft 6 (19) of the rotor rotates in bearings 4 (20) and 20 (25), which are installed in the covers. Power is supplied to the rotor winding (excitation winding) through brushes and slip rings 3 (27). The position numbers in the figure are indicated in parentheses. 9.7. NOTE The slip rings of the generator 94.3701 have a reduced diameter (compared to the generator 37.3701) to reduce the peripheral speed and reduce brush wear.

The connection diagram of the generator 37.3701 is shown in Fig. 9.8. The voltage to excite the generator when the ignition is turned on is supplied to terminal “B” through the control lamp 5 and resistors 9 connected in parallel. After the engine is started, the excitation winding is powered by three additional diodes installed on the rectifier unit. In this case, no current passes through the control lamp and it does not light up. The control voltage is supplied to terminal “B” of the voltage regulator directly from terminal “30” of the generator. The “Ш” pin of the regulator is not marked. Brush 13 is connected to it (see Fig. 9.6). The connection diagram of the generator 94.3701 is shown in Fig. 9.9. 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 5 located on the instrument panel. When you turn on the ignition on a VAZ 2108, VAZ 2109, VAZ 21099 car, the lamp should be on, and after starting the engine, it should go out if the generator is working. A brightly burning lamp or glowing at full intensity indicates a malfunction. After starting the engine, the excitation winding is powered by three additional diodes installed on the generator rectifier block. Since 1996, the generator 37.3701 has had a new design for the voltage regulator and brush holder. Now the voltage regulator is placed in a metal case and riveted to the brush holder (see Fig. 9.6, a), i.e. forms an inseparable knot with it. The new voltage regulator does not have terminal “B”, and voltage is supplied only to terminal “B”. In terms of their characteristics, the old and new voltage regulators are the same and, when assembled with a brush holder, are interchangeable. On small lots of VAZ 2108, VAZ 2109, VAZ 21099 cars, generators made in Bulgaria, Slovenia or Germany can be installed. These generators are interchangeable with the 37.3701 generator in terms of characteristics and installation dimensions, but differ slightly in design. This section of the site describes only the domestic generator 37.3701 as the main one for cars of the VAZ 2108, VAZ 2109, VAZ 21099 family.

Rice. 9.9. Connection diagram for the generator system 94.3701 on a VAZ 2108, VAZ 2109, VAZ 21099:

1 - battery;
2 - generator; 3 — mounting block; 4 — ignition switch; 5 - battery charge indicator lamp, located on the instrument panel WARNING The negative of the battery must always be connected to ground, and the positive must be connected to terminal 30 of the generator.
Failure to turn the battery back on will immediately cause increased current through the alternator diodes and damage them. It is not allowed to operate the generator with the battery disconnected. This will cause short-term overvoltages to occur at terminal “30” of the generator, which can damage the generator voltage regulator and electronic devices in the on-board network of the VAZ 2108, VAZ 2109, VAZ 21099. It is prohibited to check the functionality of the generator “for spark” even by briefly connecting terminal “30” of the generator with "mass". In this case, significant current flows through the diodes and the diodes are damaged. The generator can only be checked using an ammeter and voltmeter. The diodes of the generator rectifier unit must not be checked with a voltage of more than 12 V or with a megger, since such a device has a voltage that is too high for the diodes and the diodes will be broken during testing (a short circuit will occur). It is prohibited to check the vehicle's electrical wiring with a megger or a lamp powered by a voltage of more than 12 V. If such a check is necessary, you must first disconnect the wires from the generator. The insulation resistance of the stator winding with increased voltage should only be checked on a bench and always with the terminals of the phase windings disconnected from the diodes. When electrically welding components and parts of the car body, you should disconnect the wires from all terminals of the generator and battery. USEFUL TIPS If the alternator belt breaks along the way, and you forgot the spare one at home, you can temporarily replace the alternator belt with a 20 mm wide ring cut from an old car inner tube. To reduce current consumption when driving a VAZ 2108, VAZ 2109, VAZ 21099 with a faulty generator, if possible, turn off the radio, unnecessary lighting devices, heater fan, heated glass, etc.

removal and installation of generator 94.3701 on VAZ 2108, VAZ 2109, VAZ 21099 cars

car starter VAZ 2108, VAZ 2109, VAZ 21099 starter design features

Generator VAZ 21099, VAZ 2109, VAZ 2108

Cars of the VAZ “8, 9, 99” family equipped with a carburetor, fuel injection system (injector) are equipped with generators of type 37.3701, 94.3701.

Both power supplies are AC, three-phase, with pre-installed rectifier and voltage regulator. The rotation side is right.

The first type of power source (hereinafter - IP) is driven by a V-belt, and the second - by a poly V-belt from the crankshaft pulley. Some production models of the “eight” and “nine” are equipped with IP made in Slovenia, marked AAK-5102.

If AAK-5102 fails, it can be completely or partially replaced by 94.3701. The process of self-prevention is not at all complicated, but it requires knowledge and initial experience in vehicle maintenance. Carrying out diagnostics in a non-professional manner does not guarantee the functionality of the equipment.

What generator is installed on the VAZ 21099, VAZ 2109, VAZ 2108

Note to the driver. If the IP drive belt breaks along the way, and you don’t have a spare one at hand, cut a 25 mm wide ring from the car inner tube.

To significantly reduce current consumption when the power unit is running, it is necessary to turn off the maximum number of current consumers: radio, radio, lighting, cooler, stove heater.

Technical characteristics of the VAZ 2108 generator

The following generator models are installed on VAZ 2108 cars:

1. 3701
2. 3701

Technical characteristics of the first:

• The value of the delivered current (at 6000 rpm-1 and a voltage of 13 V) – 55 A — The voltage value – 13.6 – 14.6 V
• Rotor rotation direction – right – Maximum rotor speed – 13000 rpm-1
• Engine/generator gear ratio 1/2.04

Technical characteristics of the second:

• The value of the delivered current (at 6000 rpm-1 and a voltage of 13 V) – 80 A — The voltage value – 13.2 – 14.7 V
• Rotor rotation direction: right

A normally working, serviceable generator of VAZ 2108, 2109, 21099 cars and their modifications produces a voltage in the range of 13.6 V - 14.6 V. This can be visually tracked by a voltmeter on the instrument panel, but it is better to measure the voltage with a voltmeter (multimeter, autotester

Generator set price for VAZ 21099, VAZ 2109, VAZ 2108

The principle of operation of the power supply VAZ 21099, VAZ 2109, VAZ 2108

There are 6 coils mounted inside the generator set, the material is copper, the connection is star-shaped. The stator is a stationary structure, and the rotor rotates inside the stator. Magnetic brushes are pressed into the back of the rotor axis, and the excitation winding is wound and sealed.

After the key is turned in the ignition switch, the current from the battery creates a magnetic field, passing through the graphite brushes and copper winding. Alternating current is converted to direct current.

On the front side of the IP there are two power outputs with polarity “+” and “-”. Terminals with the appropriate polarity are connected to the battery.

To turn the generator set you will need a battery. After the battery has accumulated the spent amount of energy, the generator distributes the excess to other power sources. Thus, the size of the on-board network is maintained within an acceptable range.

Replacement and repair of generator on VAZ 21099, VAZ 2109, VAZ 2108

Power supply location: engine compartment, to the right in the direction of travel of the vehicle.

Required materials and tools:

• open-end, spanner wrenches;
• knob, heads;
• torque wrench for precise clamping force;
• new drive belt as needed;
• plastic spatula for removing the belt;
• screwdrivers with a set of bits to change the brushes.

Step-by-step replacement instructions:

• We turn off the car engine.
• Open the hood.
• Loosen the terminals and remove them from the battery.
• Loosen the bolt that secures the bracket.
• We bring the generator set down.
• Remove the drive belt.
• We remove the IP from the engine compartment for further prevention.
• Upon completion of the diagnostic work, install the parts in reverse order.

After dismantling the IP, the master cleans it, performs an initial inspection, and determines possible breakdowns. The components are replaced with new ones, the terminals on the rotor are cleaned.

The part cannot be installed if cracks are found in the housing. Subsequent operation of the technical device is unsafe.

We check the integrity of the rotor winding with a multimeter. The diode bridge is also subject to prevention. Do not forget to check the integrity of the fuse, replace it with a new one as necessary, and observe the amperage.

Subject to the recommendations of specialists, subsequent maintenance of the power source after 30 - 40 thousand km.

To extend the life of electrical equipment, follow the technical inspection schedule. Purchase parts with original catalog numbers; a complete list of serial numbers is indicated in the table data.

Contact service station specialists for help if you encounter any difficulties with repairs or maintenance of electrical installations.

How to remove the generator on a VAZ 2108 yourself step by step instructions

In order to remove the VAZ 2108 generator with your own hands, you must perform the following procedure:

1. In order to easily remove the VAZ 2108 generator, it is necessary to remove the engine protection.

2. During the dismantling process, the VAZ generator must be removed together with the bracket, since its fastening bolt will be impossible to pull out due to the position of the body side member.

3. Now disconnect all electrical terminals from the generator

4. Then you need to loosen the adjusting nut and the generator mounting nut from below.

5. Move the generator forward and remove the loose belt

6. Unscrew the bolt and remove the adjusting bar

7. We find it at the bottom of the engine compartment (shown in the photo) and unscrew the two bolts securing the bracket.
8. Then, carefully pushing down, remove the VAZ 2108 generator

9. After repairing or purchasing a new generator, we install it in the reverse order, taking into account the fact that the long bolt securing the bracket should be closer to the generator drive.
10. After completing the installation of the VAZ 2108 generator, tension the drive belt

The best generators for VAZ

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.

How to check the generator?

To check the functionality of the unit in your car, you need to follow these steps:

1. Using a voltmeter, diagnose the voltage at the battery terminals. When the engine is running and the generator unit is operating normally, this parameter should be around 13.8-14.5 volts.
2. Try placing your palm on the unit body with the engine running, you need to feel the vibration. If there is vibration, you will notice it immediately. Moreover, it may be due to wear of bearing parts.
3. It is also necessary to diagnose the tension of the device strap, while the motor must be turned off. Press the strap with your finger - the deflection should be no more than 1.5 cm (video author - Vyacheslav Lyakhov).

Generators for VAZ 2106 and 2107

The generator on the VAZ 2106-2107 costs the same as on the VAZ 2101 - G221. If you install additional external current consumers that operate constantly, this will lead to undercharging and insufficient current will be supplied from the relay regulator. These additional devices include:

• powerful audio systems;
• fog lights;
• TV;
• preheater;
• additional heater;
• fridge.

Any similar device will lead to greater power consumption and, consequently, to premature battery discharge, even when the engine is running at high speeds. Standard devices for 2106 were developed a long time ago and are not designed for modern energy-consuming add-ons.

In this case, it is recommended to replace the standard generator with a more powerful unit.

What to install?

G 222

If you need to increase the current power, then, when deciding which generator is better to install on the VAZ 2106 or 2107, instead of the standard one, take the G 222, which was installed on the VAZ 2105, Nivakh. It would seem that it itself is no better than the standard one on the “six”, but you can take an upgraded version that will be more powerful. Unlike the 221, this unit is designed with a built-in regulator relay, assembled into one unit with brushes. The G 221 gives an output of 42 A, and the 222nd - 50 A. Increasing the cross-section on the rotor winding increases the power, although the design is completely similar to the G 221. However, to install it on the 2106 you will need minor modifications. The easiest way is to install brushes from G 221. They fit perfectly in place of the relay. This modification is quite feasible even for car enthusiasts who do not have the skill.

It can be installed on a VAZ 2106 G222 with a standard regulator, but then it is necessary to change the connection diagram of the electrical machine.

On 2107 everything is installed without problems.

Check the voltage at medium engine speeds at the battery terminals, if it is 14 V at 2500 rpm, then everything is fine. You can drive with a more powerful unit by connecting additional options.

Generator 2108

This installation has greater efficiency, delivering a current of 55 A. It is installed on both 2106 and 2107.

The mount is identical to the standard ones, there are no problems during installation. Just remember to remove the battery terminal. You'll have to tinker with the connection to 2106. There are 4 wires going to the standard device. On the “eight” - three, since the voltage relay is built-in. To get a good result, insulate the black wire, connect the rest according to the standard system. The light bulb - the discharge indicator will light up when the generator is running, and will go out if there is no charging.

It is useful to make some more minor modifications. Instead of the old relay, install a regular power one. Then the light comes on only when the engine starts and at low speeds.

On 2107 you only need to add a power relay.

2107-3701010

An even more powerful installation is from the VAZ 2107i, producing 80 A, which can also be installed on the VAZ 2106–2107. With such equipment it is possible to install any electrical systems. For VAZ 2106 only 2107-3701010 is suitable; You can use any generator of this series for the carburetor “seven”.

When installing this equipment on 2106, it is better to modify it: replace the relay regulator with a similar one from G 222.

Replacing the generator on a VAZ 2108, VAZ 2109, VAZ 21099

Welcome! A generator is an integral part of any car, the generator supplies current to the on-board network, which is generated when the generator pulley rotates. Thanks to this, the battery does not have to work constantly and after starting the engine, it stops supplying current to the on-board network of the car, and only one starts supplying it. generator, but there are cases when it fails (Over time, this usually happens because sand and other types of dirt get into the generator, or the generator can simply burn out due to a short circuit) and it becomes impossible to drive a car, since One battery turns on, and when it is completely discharged, the car will stall and simply won’t go anywhere, so the generator needs to be changed when it becomes unusable or repaired (we will still touch on the topic of repairing the generator in this article).

Note! To change the generator, you don’t need a lot of time and tools, it will be enough to stock up on: Several keys, one of which should be “17” and the other about “19” and a pry bar or something like it (A stick, for example)!

Summary:

Where is the generator located? It is located between the TV and between the engine, when you open the hood you will immediately see it, but it will only be attached a little differently, not as shown in the photo, but the location will be exactly the same, for clarity it is indicated in the photo below with a red arrow.

When should the generator be replaced? 1. You can understand whether it provides charging or not at all in two ways, which one you choose is up to you, we usually recommend the first method to all those people who ask us a question about how to check the generator for serviceability, and it is as follows: You can buy a multi-meter at any auto store (It is available almost everywhere), the Chinese ones are quite cheap (About 300 rubles), You do not work at the station and are not an electrician, so this multi-meter will be quite enough (If you want, of course , you can get it for more expensive), in general, you buy this device and turn on the Voltmeter function on it, after which the leads coming from the multi-meter are connected to the battery (see photo below) and pay attention to the device (If the battery is working and charged, then it will have to give out at least 12.5 Volts, if it gives out less than 12, then it needs to be charged), now the next step is to start the car and the wires coming from the multi-meter are connected in exactly the same way as before (the function should still be turned on on the device Voltmeter) and the device is looked at again, the readings of the device will definitely increase, but if they fall, then the generator is not working properly and does not charge the battery (Also look at the charge lamp, see the small photo, if it is on and the readings of the device with the engine running gradually fall, then the generator is 100% faulty).

2. Now let’s talk about the second method, let us immediately warn you that it is free, but it can have a very bad effect on the generator, this is how it is done, start the car and the choke is pulled out (it is generally not recommended to do this on an injector), so after the choke is pulled out ( Halfway somewhere, so that the engine runs at 1500 rpm) and the car works for a while (A minute is enough, even less), the minus terminal is removed from the battery, and after removal the car will definitely have to continue its work (This indicates that the on-board network the car, and the ignition is powered from the generator and not from the battery), but if it stalls immediately, then the generator does not work (The brushes are worn out or the diode bridge is burned out), in general, such a generator will have to be removed and checked for serviceability (By the way, about how repair the generator, read the article: “Repairing the generator on a VAZ”) but there is one big minus, if the generator is not working correctly (This happens because of the brushes) but it still works, then the car will not stall and because of this, it will always the car's battery is discharged and therefore, to find out more accurately whether it provides charging and whether it gives it as it should, you can only find out with a multi-meter and by the way, if you buy this device, you will not regret it, since it will be very useful to you in the future .

Lada Priora - generator replacement

The Priora requires a powerful generator; the car has a lot of electronics and a weak installation cannot cope with it.

A generator labeled 5102.3771 is recommended for the Priora, providing a power of 80 A; on luxury versions with even more electronics, a 115 A device is installed. Then which generator is better to install on the Priora?

Car owners recommend a unit produced by KZATEtm Samara plant under number 9402.3701-14, producing 115 A.

There is no need to modify it during installation, you just need to find the connector, because there are differences from the standard one. You can use a plug from a VAZ-2108 from the limit switch for turning on the reversing lights, which costs only 20 rubles.

Next, you will have to make a little modification when connecting to the “B+” power terminal in order to fit it to the desired size.

The cost, of course, of domestic units is higher than that of Chinese or Bulgarian ones, sold for 2200 and 3000, respectively. For Russian ones they ask for about 4000. But if you need repairs with Russian-made components, you can easily find spare parts.

Which generator is better to put on a VAZ 2110

VAZ 2110 factories install KATEK generators with a current of 80 A. The service life is 140,000 km, which is approximately 10 years of vehicle operation. Answering the question of which generator is better to install on the VAZ 2110, experts recommend products from Russian manufacturers.

What to consider when choosing

• Russian manufacturer or foreign? Of course, first of all, Russian manufacturers are preferable. If only because it is easier to find spare parts in the event of a minor breakdown. If you purchase a generator for a VAZ 2010 from a not so popular company, it may be difficult to find spare parts, and they will not cost you so much.

• Current strength. Factory models for VAZ 2010 - 3771 or 94.3701 - are designed for 80 A, this current is enough, even if there are additional devices that consume it. More powerful ones - 120 A - are installed in the presence of powerful acoustics, no harm is done to the battery, and you will provide all energy consumers with uninterrupted current.
• It is better to purchase a generator if there is a warranty on it. There may well be a defective product, and the warranty will provide the opportunity to replace it with a new one.

Generator Manufacturers

It is best for 2010 to purchase a standard generator from KATEK or KZATEtm Samara plant, and about 50% of owners do just that, according to statistics. They are reliable, cope perfectly with their functions, creating the necessary tension.

Among the foreign-made generators, we can recommend Bosch, Delphi and Denso, which are also reliable and popular.

Generators for VAZ 2114

The generator initially built into the 2114 is low-power, and if it also breaks down and you decide to purchase a new one, the question arises: which generator is better to install on the VAZ 2114? It is important here that the unit is more powerful, but there is no need to change the fastenings.

1. The most successful replacement option for a VAZ 2014 is a generator from a Priora or Kalina with air conditioning. This installation has a power of 115 A, which is 35 A more than the characteristics of the units.

Installing these generators for 2014 usually does not cause problems, however, it will be necessary to replace the pulley, but it only costs about a hundred rubles and is not difficult to find.

1. The Eldix brand generator also has a power of 115 A and works well. The disadvantage is that it is almost impossible to find spare parts, and even if there is a minor breakdown, you will have to replace the entire generator instead of repairing it.

Please note that a lack of charging voltage can occur simply due to oxidation of the battery terminals; keep an eye on them by cleaning them regularly.

Installing a generator on a VAZ 2108

Finally bought some goodies for my eight to install a generator)))

not a complete set

What I needed:

1. Generator 115A 2. Lower mounting of the VAZ 21082 generator with mounting bolts! 3. Upper fastener for 8-valve valves 4. Alternator belt (this is a separate topic) 5. Plug for genes or small mother

I didn’t install it myself, so I’ll describe everything from the words of the master.

Everything fit without problems, except the belt. To find the one we needed, we traveled all over the city. As a result, it came from 8-mic valves of the first generation. I can’t write more precisely.

After installation, with a sharp acceleration of the gene, the spar caught (perhaps my muzzle was behaving) I had to distort it, but in the end it worked.

I also read that a 330 Ohm 5 W resistor should be installed on the “L” contact, where the gene excitation wire is connected... But I haven’t found it yet.

Generators for VAZ 2115

VAZ 2115, created on the basis of the “nine”, adopted the main components and assemblies from it. Accordingly, there are also many problems with equipment. If the car has a carburetor engine, it can be equipped with a 55 A generator 37.3701, which differs from the above in the mounting method. However, this voltage is not enough for the constant use of modern audio systems, fog lights and other energy-consuming options. Which generator is better to install on a VAZ 2115 - car owners definitely recommend installing it with a power of at least 80 A. Now on the VAZ 2115, as well as on 2113-2114, three-phase 94.3701 with an output of 80 A are installed.

For more power, you can install a 90 A Priorov generator KZATE 9402.3701 in 2015, which is suitable for the mounting and pulley. A reliable unit will provide you with the necessary energy for any number of energy-consuming devices.

Summarizing the above, it can be noted that when buying a generator at a VAZ to replace a broken one or to increase power, it is better to choose Russian models, since they are most suitable in design and you will not have to carry out expensive modifications. In addition, you will always find the necessary
