Voltmeter Test
WARNING: This page is about a different car, the 1994 Buick Skylark. However, it is still accessible from the selected car via links, so may be relevant.
- With ignition switch in RUN position, connect voltmeter between positive and negative terminals of battery. If voltage reading on voltmeter is same as vehicle's voltmeter, vehicle's voltmeter is okay.
- If voltage is not consistent with vehicle's voltmeter, check Pink/Black wire and Black wire of IPC connector for open circuit. If wires are okay, replace IPC. See INSTRUMENT PANEL CLUSTER (IPC) R & I under REMOVAL & INSTALLATION.
