Gauge Cluster (LeSabre)
- Turn ignition off. Disconnect instrument cluster connector. Turn ignition on. Measure voltage between instrument cluster connector terminal A9 (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 B10 (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 B2 (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 A9 (Pink wire) to terminal A11 (Black/White wire), then terminal B3 (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 B10, A9, B2, A11, and B3. If all circuits are okay, replace instrument cluster.
