Voltmeter Reading Is Inaccurate

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 1997 GMC Savana Special, 1997 GMC Savana Camper Special, 1997 GMC Savana, 1997 Chevrolet RV Cutaway, and 1997 Chevrolet Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

Connect voltmeter between battery terminals. If voltmeter reading is same as voltmeter in vehicle, voltmeter is okay. If voltmeter reading is different than that of vehicle voltmeter, replace instrument cluster. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION.
