Ignition Coil Resistance

  1. Remove primary and secondary leads from ignition coil. Using an ohmmeter, check resistance between primary terminals "A" and "C" (Accord) 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 "A" and "B" terminals (Odyssey and Prelude) or terminals "A" and "C" (Accord). Continuity should exist. If readings are not within specification, replace coil.
