Ignition Coil Power Source

  1. Turn ignition off. Disconnect ignition coil relay harness connector. Turn ignition on. Connect negative voltmeter lead to ground. Connect positive lead to one harness Yellow/Black wire and then to the other Yellow/Black wire. Battery voltage should be present on both terminals.
  2. If battery voltage is not present, check harness continuity between ECCS relay and EFI harness connector (Yellow/Black wire) and 7.5-amp fuse in fuse box.
