Component Testing: Voltmeter

1. Remove instrument cluster, leaving wires connected. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION. Using a DVOM, measure voltage at vehicle voltmeter terminals. SeeFig 1 .
2. With ignition switch in ON position, compare readings on both voltmeters. Voltage difference between voltmeters should be less than .5 volt. Replace gauge if reading is not as specified.
