Ignition Coil Resistance (External Coil)

  1. Turn ignition off. Remove primary and secondary leads from ignition coil. Using an ohmmeter, check primary resistance between ignition coil connector terminals "A" and "B". See Fig 1 . Resistance should be as specified. See IGNITION COIL RESISTANCE  .
  2. Check secondary resistance between ignition coil connector terminal "A" and secondary output terminal (coil tower). See IGNITION COIL RESISTANCE  . Check for continuity between terminals "A" and "C". Continuity should exist. If readings are not within specification, replace coil.
