Cluster Power & Ground Test
WARNING: This page is about a different car, the 1997 Buick LeSabre. However, it is still accessible from the selected car via links, so may be relevant.
- Turn ignition off. Disconnect instrument cluster connector. Turn ignition on. Measure voltage between instrument cluster connector terminal B1 (Pink wire) and ground. If battery voltage is not present, check Pink wire for an open circuit.
- If battery voltage is present, measure voltage between instrument cluster connector terminal B9 (Pink wire) and ground. If battery voltage is not present, check Pink wire for an open circuit.
- If battery voltage is present, measure voltage between instrument cluster connector terminal B3 (Pink wire) and ground. If battery voltage is not present, check Pink wire for an open circuit.
- If battery voltage is present, measure voltage between instrument cluster connector terminal B1 (Pink wire) to terminal B6 (Black/White wire), then terminal B7 (Black/White wire). If battery voltage is not present in both cases, check Black/White wires for an open circuit. If battery voltage is present, check instrument cluster connector for good contact at terminals B9, B3, B1, B6, and B7. If all circuits are okay, replace instrument cluster.
