Component Testing: Voltmeter

1. Disconnect battery negative cable. Remove instrument cluster. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION.
2. Using ohmmeter, measure resistance between IGN and GND terminals. SeeFig 1 . Resistance should be approximately 178 ohms. If resistance reading is not as specified, replace voltmeter.
