When checking system of charging act as follows:
If the control lamp of battery charging does not burn at inclusion of ignition, check reliability of connection of wires to the generator, serviceability of a control lamp and integrity of its chain.
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 battery 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 the regulator of tension as follows:
Connect the voltmeter to the rechargeable battery and launch the engine.
Increase the frequency of rotation of the engine before stabilization of indications of the voltmeter which has to show 12–13 V, but no more than 14 Century.
Include the maximum number of consumers of the electric power (headlights, a heater of back glass, the heater fan).
At the same time tension developed by the generator with tension regulator has to make 13–14 Century.
If tension does not correspond to these values, can be a cause of defect: worn-out brushes of the generator, weak springs of brushes, faulty regulator of tension or diode, break of a winding of the stator or defective contact rings of a rotor.
