As an introduction a small educational program on automotive generators. The voltage of the electricity generated by the specified device at different speeds, is regulated through the excitation winding and is maintained constantly in the range of 13.8 to 14.2 volts.
The task of providing consumers with the vehicle's current specified nominal value is assigned to the voltage regulator (PH). The connection of the generators is done according to different schemes, depending on the brand and model, technical vehicle. So the model number VAZ, AZLK-2141 and "Tavria" are equipped with devices Г222 or 37.3701, "the tenth family" Volga car is equipped with generatorsand 94.701 or AAK-5102, all of them have a built-in voltage regulator (commonly called "chocolate" or "tablet").
Removing the voltage from the generators is carried out with the large terminal, which is connected to the positive battery terminal and marked as: "30", "+", "In", "I+" or "BAT". The negative terminal of the windings and a diode bridge are designated: "31", "–", "D", "DF", "B", "M", "E" or "GRD". Terminal voltage regulator for supplying power thereto from the vehicle when the ignition switch marked: "15", "B" or "S". And the connector: "61", "D", "D+", "L", "WL" or "IND" is designed to supply power to the control charge lamp.
When to stop charging the battery, as a rule, is evidence of the failure of the voltage regulator, despair in this case should not be. Just apply current to the excitation winding and drive to the auto shop or service station without the battery deep discharge.
Will cover this question in more detail. So, if an error occurs in the PH, it is dismantled, and to excite the generator Г222 and force him to continue working, connecting insights "In" both devices, and "W" (voltage regulator) – it is necessary to cut.
Then during Assembly the withdrawal "W" connects cut any wire to ground of brushes. From terminal "30" of the generator is disconnected and insulated wire, and a chain output "15" sequentially the light, of a power not exceeding 15 watts.
For excitation of alternators 94.3701 37.3701, and after disconnecting the PH of the same light bulb is connected to the output.
