Ignition Coil Resistance (Internal Coil)

Turn ignition off. Remove distributor cap. Remove primary leads from ignition coil. Using an ohmmeter, check primary resistance between ignition coil terminals "A+" and "B-". See Fig 1 . Resistance should be as specified. See IGNITION COIL RESISTANCE .

Check secondary resistance between ignition coil terminal "A" (+) and secondary output terminal (coil tower). See IGNITION COIL RESISTANCE . If readings are not as specified, replace ignition coil.
