Circuit Test

  1. Disconnect instrument cluster harness connector. Check voltage between ground and instrument cluster harness-side connector terminal No. 33 (White wire). See WIRING DIAGRAMS  . Voltmeter should read 5 volts. If voltage is as specified, go to next step. If voltage is not as specified, go to step  4 .
  2. Check continuity between ground and instrument cluster harness-side connector terminal No. 34 (Black wire). Refer to the WIRING DIAGRAMS  . If continuity is present, go to next step. If continuity is not present, go to step  5 .
  3. Check voltage between ground and instrument cluster harness-side connector terminal No. 42 (Black/White wire). Refer to the WIRING DIAGRAMS  . Battery voltage should be present. If battery voltage is present, replace tachometer. If battery voltage is not present, go to step  6 .
  4. Check harness connectors to ECM, instrument cluster or distributor assembly. Repair as necessary. If connectors are okay, check circuit between ECM, instrument cluster and distributor. See WIRING DIAGRAMS  . Repair as necessary.
  5. Check joint connector to instrument cluster. Repair as necessary. If connector is okay, check circuit between instrument cluster and ground. See WIRING DIAGRAMS  . Repair as necessary.
  6. Check harness and joint connectors to power supply junction block. Repair as necessary. If connectors are okay, check circuit between instrument cluster and power supply. See WIRING DIAGRAMS  . Repair as necessary.
