Volt Meter Gauge: Testing and Inspection

Voltmeter Pins:

1. Remove the voltmeter assembly from the cluster.
2. Connect a volt/ohmmeter between the B+ pin and the Ground pin. Turn the ignition switch to the ON position and check voltmeter reading.
^ The dot on the vehicle's voltmeter corresponds to 13 volts measured between the ignition pin and ground pin.
3. If the voltage varies, estimate proper gauge needle position by the actual voltage measured.

Multiple Gauge Malfunction

If the Voltmeter, Speedometer, Tachometer, and other gauges appear to be malfunctioning, proceed as follows:
1. Remove the cluster.
2. Check for ignition voltage at cavity 9 of the red cluster connector and ground.
^ If voltage is not present, repair open circuit.
3. Check for ground continuity between cavity 14 of the red cluster connector and ground.
^ If a good ground is not present, repair open circuit.
4. If circuits are OK and pins or connectors are not distorted, replace the printed circuit board.
