Volt Meter Gauge: Testing and Inspection

The voltmeter is a gauge which measures the electrical flow from the battery to indicate whether the battery output is within tolerances. The voltmeter reading can range from 13.5---14.0 volts under normal operating conditions. If an undercharge or overcharge condition is indicated for an extended period, the battery and charging system should be checked.

TROUBLESHOOTING
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.
