1. Connect the digital voltmeter probes to the battery terminals. |
2. Make sure the parking brake is fully tightened. On vehicles with automatic transmission, set the selector lever to position PARK. On vehicles with a manual transmission, set the gear lever to the neutral position. |
3. Make sure that all consumers of electricity are turned off. |
4. Turn on the ignition and starter and observe a voltmeter. |
5. If the voltage is lower than 9.6, remove the starter and perform bench tests. If a bench test gave a negative result, replace the starter. |
6. If the voltage is higher than 9.6 V and the current consumption is below the required value, carry out checks on the voltage drop. |
7. If the voltage shown by the voltmeter 12.5 V or more, and the starter does not work, check the efficiency of the traction relay. |
8. If the voltage shown by the voltmeter 12.5 V or more, and the starter turns engine crankshaft slowly, inspect voltage drop. |
