Voltmeter System Test

NOTE: This test is only for vehicles equipped with a voltmeter.

1. With ignition switch in the off position, the voltmeter should not move.
2. With ignition switch in the run position with engine running and no electrical accessories on (fully charged battery), needle will move into the white marked area.
3. If the needle remains in the red marked area with no electrical accessories operating, or remains off scale, check for loose connections on the voltmeter or an open circuit wire prior to replacing the gauge.
