Volt Meter Gauge: Testing and Inspection
To check voltmeter, turn key and headlights ON with engine OFF. Pointer should move to 12.5 volts. If no needle movement is observed, check
connections from battery to circuit breaker. If connections are tight and meter shows no movement, check wire continuity. If wire continuity is
satisfactory, the meter is inoperative and must be replaced.
