1. Connect щупы the digital voltmeter to plugs of the storage battery. |
2. Be convinced that the parking brake is completely tightened. On cars with an automatic transmission establish the selector lever in PARK position. On cars with a mechanical transmission establish the gear shifting lever in neutral situation. |
3. Be convinced that all consumers of electric energy are switched off. |
4. Include ignition and a starter and watch voltmeter indications. |
5. If tension is lower 9,6 In, remove a starter and carry out bench tests. If bench tests yielded negative result, replace a starter. |
6. If tension is higher 9,6 In, and the consumed current is lower than demanded value, inspect on power failure. |
7. If the tension shown by the voltmeter 12,5 B or more, and a starter does not work, check operability of the traction relay. |
8. If the tension shown by the voltmeter 12,5 B or more and a starter turns a cranked shaft of the engine very slowly, inspect on power failure. |
