Ignition Coil Resistance

  1. Remove distributor cap. Remove 2 Phillips screws retaining primary ignition leads to ignition coil. Remove primary leads from ignition coil. Using an ohmmeter, check resistance between primary terminals "A" and "B" on ignition coil. See Fig 1 . Resistance should be .3-.5 ohms at room temperature.
  2. Check secondary resistance between terminal "A" and secondary output terminal (coil tower). Resistance should be 9440-14,160 ohms at room temperature. Replace coil if readings were not within specification.
