Ignition Coil Resistance

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