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.
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.

Modern vehicles have many basic and additional equipment that require electric current to operate. The source of such current in the car is the battery, and to recharge it while the engine is running, a generator set is installed.
Generator
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.

One day the car stopped starting from a dead battery, I charged the battery and drove it for 3 days after which it was discharged again. At that time I was still just a novice motorist, so I immediately thought that the battery was faulty, I bought a new one in the store, brought it and installed it, literally 5 days later the car would not start again because the battery was dead. I went to the store and demanded a replacement, after much persuasion from the manager, they finally agreed to replace the battery. Well, history repeated itself, then I realized that I had to go to a car service center; they didn’t tell me about the generator malfunction. This is how I unknowingly killed a lot of nerves and time.

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.
Recharging the battery
Sometimes a generator malfunction is associated with overcharging the battery. It can be identified by its characteristic signs: the headlights shine brighter than usual, the battery charge indicator is constantly on. If the voltage exceeds the norm, this may cause the battery to boil over. Overcharging is most often caused by a broken voltage regulator. In a VAZ 2115 car, this part can be easily replaced by yourself.
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.
- 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.
- 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.
BEARINGS
The generator on a VAZ 2114 car consists of the following main parts:
- A housing consisting of two aluminum covers (front and back);
- Stator (winding located inside the housing);
- A rotor rotating inside the stator;
- Diode bridge;
- Voltage regulator.
The armature (rotor) rotates in two bearings, which are installed: one in the front cover and one pressed onto the rotor. Both bearings are press-fit and therefore are not that easy to replace.
There are usually two main problems with a generator:
- Charging disappears;
- Noise occurs: whistling, grinding or humming.
If there is a whistling noise under the hood, a worn alternator bearing is often to blame. Due to such a malfunction, charging is not lost, but you still shouldn’t drive with noise, since as a result the generator will jam because the rotor will stop rotating.
Before changing or starting repairs, you need to buy the necessary spare parts. And before purchasing, you need to find out what bearings are on the VAZ 2114 generator. A bearing of brand 180202 (a foreign analogue of 6202-2RS) is installed on the rear of the rotor, and 180302 (an analogue of 6302-2RS) is installed on the front cover. The cost of Russian parts is low - in the range of 50-80 rubles per piece, imported spare parts are noticeably more expensive - from 200-250 rubles. Bearings are often sold as a set, that is, in pairs. Imported analogues are of much higher quality, so when choosing parts it is better to buy brand 6202-2RS and 6302-2RS.
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

Operating principle of the electrical energy source
There are 8 coils installed in the GU housing. The material is copper, the connection method is “star”. The rotor is a steel shaft, on the back surface of which magnetic circuits are pressed, between which a winding is installed.
Excitation winding wires and copper-graphite brushes are soldered to the shaft rings. After the ignition is activated, the current from the battery passes through the brushes and winding, forming a magnetic field.
Thus, the rotor is driven, and the alternating current is converted into direct current through the coils.
On the back side of the GU there are two terminals marked “+” and “–”. Accordingly, the terminals with the indicated polarity are connected to the battery.
To rotate the PG you need a battery. When the actual voltage during operation of the unit is higher than the battery voltage, the generator will begin to supply power to the battery consumers. Thanks to this, the on-board network current is maintained within a specified range.
