Instrument Panel - Analog: Testing: Voltmeter

Turn ignition on. Turn headlights on. Set heater blower fan to HIGH position. Voltmeter pointer should move toward lower voltage scale.
If pointer does not move, ensure fuses are good. Check wiring between battery and circuit breaker and from circuit breaker to instrument cluster. If connections are secure, remove instrument cluster. See INSTRUMENT CLUSTER R & I . Ensure cluster connector has battery voltage. If voltage exists, replace gauge.
