Ignition Coil Resistance

Remove primary and secondary leads from ignition coil. Using ohmmeter, check primary resistance between positive and negative terminals of coil. See Fig 1 and Fig 2 . Resistance should be as specified in IGNITION COIL RESISTANCE table. If resistance is not as specified, replace ignition coil.
Check secondary resistance between (positive) terminal and coil tower. See Fig 1 and Fig 2 . See IGNITION COIL RESISTANCE table. If resistance is not within specification, replace coil.
