| 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 should show from 12 to 13 volts, but no more than 14 volts. |
| 3. Include the maximum number of electric consumers (a headlight, a heater of back glass, the heater fan). Thus the tension developed by the generator with a regulator of tension, should be in limits from 13 to 14 volts. |
| 4. If tension does not correspond to demanded sizes, worn-out brushes of the generator, weak springs of brushes, a faulty regulator of tension, the faulty diode, break of a winding of a stator or defective contact rings of a rotor can be a cause of defect. |
