7.10. System of charging

Electric circuit of system of charging

Arrangement of elements of system of charging on the car

The system of charging turns on the generator, tension regulator, the loading indicator, the accumulator, safety locks and electric wires.

If the control lamp of accumulator charging does not burn at inclusion of ignition, check connection of wires to the generator and integrity of a control lamp. If the lamp still does not burn, check an electric chain from the generator to a lamp. If all electric chains are serviceable, so the generator is faulty and it should be replaced or repaired.

If the control lamp of accumulator charging burns during the operation of the engine, stop the engine and check a state and a tension of a driving belt of the generator, and also connection of wires to the generator.

Check of the regulator of tension can be made as follows:


1. Connect the voltmeter to poles of the accumulator and start the engine.

2. Increase engine turns before stabilization of indications of the voltmeter which has to show from 12 to 13 V, but no more than 14 Century.
3. Include the maximum number of electric consumers (headlights, a heater of back glass, the heater fan). At the same time tension developed by the generator with tension regulator has to be ranging from 13 up to 14 Century.
4. If tension does not correspond to the required sizes, worn-out brushes of the generator, a weak spring of brushes, the faulty regulator of tension, the faulty diode, break of a winding of the stator or defective contact rings of a rotor can be a cause of defect.
5. If resistance differs from the required values, replace the ignition distributor.
