| 1. Connect щупы the digital voltmeter to plugs of the storage battery. |
| 2. Be convinced that the lay brake is completely tightened. On cars with an automatic transmission establish the selector lever in position PARK. On cars with a mechanical transmission establish the gear change lever in neutral position. |
| 3. Be convinced that all consumers of electric energy are switched off. |
| 4. Include ignition and a starter and observe of voltmeter indications. |
| 5. If pressure more low 9,6 In, remove a starter and conduct bench tests. If bench tests have yielded negative result, replace a starter. |
| 6. If pressure above 9,6 In, and a consumed current below demanded value, inspect on a power failure. |
| 7. If the pressure shown by the voltmeter 12,5 In or more, and a starter does not work, check up working capacity of the traction relay. |
| 8. If the pressure shown by the voltmeter 12,5 In or more and a starter turns a cranked shaft of the engine very slowly, inspect on a power failure. |
