| 1. Check a state and a tension of a belt of the generator. At detection of signs of wear replace a belt. |
| 2. Check an inhaling of bolts of fastening of the generator and an adjusting bolt of a tension of a belt. |
| 3. Check conducting of the generator and regulator of tension, reliability of fastening and a condition of sockets. |
| 4. Check safety locks. |
| 5. Start the engine and check the sound made by the generator (howling or squealing a sound points out wear of bearings or slipping of a belt). |
| 6. Check electrolyte density in the battery. If density low, charge the battery (this point does not belong to unattended batteries). |
| 7. Check battery charge degree (at faulty section of the battery its recharge is possible). |
| 8. Disconnect cables from the battery and check a condition of plugs and poles. |
| 9. Check existence of short circuit, having disconnected a cable from (-) – poles and having included a lamp between a pole and a cable. If the lamp lights up, then in a chain of the car there is a short circuit. |
| 10. Disconnect from the wire generator. If the lamp goes out, then replace the generator. Otherwise establish a chain, consistently deleting safety locks before blackout of a lamp. |
| 11. Check tension on the battery on the idle engine which has to be about 12 Century. |
| 12. Start the engine and again check tension which has to be of 14–15 Century now. |
| 13. Turn on driving beam of headlights. During the normal work of system of a charge tension has to fall and again increase. |
| 14. If tension is higher than the normal tension of a charge, then replace tension regulator (see subsection 3.3.7.4). If tension is lower normal, then the rectifier, the regulator or the generator are faulty. |
| 15. If short circuit is absent, but the battery is discharged all the time, then are the reasons malfunction of the battery, rectifier, regulator, generator (brushes, the rectifier, windings of a rotor or the stator) or a weak tension of a belt of the generator. The generator is not subject to independent repair. |
