Ignition Coil Resistance (A/T)

  1. Remove primary and secondary leads from ignition coil. Using ohmmeter, check primary resistance between positive and negative terminals of coil. See Figure -4. Resistance should be as specified in IGNITION COIL RESISTANCE  table. If resistance is not as specified, replace ignition coil.
  2. Check secondary resistance between coil towers of each coil. See Figure . See IGNITION COIL RESISTANCE  table. If resistance is not within specification, replace coil.
  3. Check insulation resistance of case. Using a 500-volt megger, measure insulation resistance between positive terminal and coil case. If resistance is not more than 10 megohms, replace ignition coil.
