Voltmeter (depending on modification) (Chevrolet Tahoe 2)

1. The voltmeter shows the voltage of the on-board network. When the engine is running, the voltmeter should show a voltage in the range of 12-16 V.

2. If the voltmeter shows a voltage of less than 11 V or more than 16 V for a long time, there may be a fault in the charging system or battery.

Note: A voltage drop to less than 11 V when starting the engine is not a malfunction.
