Ignition Coil Resistance

1994 Plymouth Laser RS Turbo, AWD, AutomaticSECTION Ignition Coil Resistance
  1. Disconnect ignition coil connector. Measure primary coil resistance between ignition coil terminals No. 1 and 3, and between terminals No. 2 and 3. See Fig 1 . Primary resistance should be .70-.86 ohm.
    CAUTION: Ensure ignition coil connector is disconnected before measuring secondary coil resistance.
  2. Measure secondary coil resistance between high voltage tower terminals for cylinders No. 1 and 4, and between high voltage tower terminals for cylinders No. 2 and 3. See Fig 1 . Secondary resistance should be 11,300-15,300 ohms. Replace ignition coil if it does not test as described.
