Ignition Coil Resistance

  1. When ignition coil is suspected of causing ignition problems, carefully inspect coil for signs of secondary circuit arcing to primary or ground circuits. This would be indicated by the presence of burned spots.
  2. Disconnect ignition coil primary 2-wire connector. Using ohmmeter, check resistance between primary connector terminals. Check secondary resistance between secondary tower and positive terminal of coil primary connector. To identify positive terminal of coil primary connector, see IGNITION COIL POWER SOURCE TERMINAL IDENTIFICATION table.
  3. If primary or secondary resistance is not within specification, replace ignition coil. See IGNITION COIL RESISTANCE table for resistance specifications.
