Ignition Coil Power Source & Ground

  1. Disconnect 3-pin ignition coil connector. Turn ignition on. Check voltage between ground and terminal "B" of ignition coil connector. See Figure.
  2. If battery voltage is not present, go to IGNITION COIL/POWER TRANSISTOR RELAY. If battery voltage exists, turn ignition off. Check continuity between ground and ignition coil connector terminal "A".
  3. If continuity does not exist, repair ground circuit between ignition coil connector terminal "A" and ground. Repeat test for remaining coils.
