VAZ voltage regulator in the modern market is represented by several models. The industry produces several brands: RN-1, 12.3702, RN-6, RN-5, RN-4 and RN-2. The first two models are the simplest, respectively, and cheaper. However, they differ greatly in their characteristics, depending on the circumstances. If the VAZ voltage regulator is discharged, the characteristics also decrease. At the same time, if the terminals are oxidized or the terminals are loosened, the resistance in the circle will increase. In this case, you may need to check the voltage regulator.
Sometimes, in order to adjust it, you will need to thoroughly soak the contact, having previously twisted the terminals on the terminals and loosened the clamps. After a certain time, it will not be superfluous to cover the voltage regulator with a thin layer of technical petroleum jelly. This will help prevent oxidation. However, if the battery is not used for a long time, it is best to store it at sub-zero temperatures. In this case, its discharge will be minimal. In the event that during storage the electrolyte density is greatly reduced, the car voltage regulator needs to be recharged.
During operation of such a battery, special attention should be paid to the cleanliness of the external surface and the integrity of the mastic layer. If at least one wiring has come off the brush that the generator is equipped with, then in order to connect it, you must make a special hole in the end, the diameter of which will exceed the diameter of the wire by at least 0.3 millimeters. After that, it is worth pouring a notch with glue, for example, BF-2, which is mixed with graphite crumb. Hardened, the glue can firmly fasten the wire and brush.
But the voltage regulator RN-6 is equipped with a special device designed to disconnect the winding of this device in the event that the engine stops working. That is why it is best to choose batteries of brands RN-6, RN-5 and RN-4. For example, it is always possible to replace a VAZ-2108 or 2109 voltage regulator with spare parts having charging warning lamps. On those VAZ vehicles that are equipped with a G221 generator, regulators of the RN-6, RN-5 and RN-4 brands are mounted instead of models such as the PP380, using its own fastening pins.
In any case, even for novice motorists, the connection diagram of the regulator should not cause difficulties. First of all, it is worth considering that for the load it is best to use the rotor winding of a regular generator. In extreme cases, you can choose a conventional incandescent bulb, but in this case, you can cross off the ammeter from the circuit.
The technique by which the VAZ voltage regulator-voltage regulator is configured is not so complicated, but often you still have to go to the auto repair shop. In the event that a “floating” defect was noticed during the operation of the generator, experts recommend soldering the problem areas. But at the same time, it is forbidden to use acid fluxes, since they conduct electric current well. An excellent connection is obtained using a completely ordinary rosin.
