Ignition Coil Resistance

  1. Disconnect wiring from ignition coil so ignition coil is isolated from the system. Using ohmmeter, check primary resistance between ignition coil positive (+) and negative (-) terminals. See Fig 1-20.
  2. Check secondary resistance between ignition coil positive (+) terminal and high tension wire terminal (coil wire tower). See Fig 6-25. Replace ignition coil if resistance is not within specification. See IGNITION COIL RESISTANCE  table.
