Ignition Coil Resistance (Millenia 2.5L)

1. Disconnect 3-pin harness connector. Using ohmmeter, measure primary resistance between terminals "A" and "B". See Fig 1 . Resistance should be as specified. See IGNITION COIL RESISTANCE  table. If resistance is not as specified, replace distributor.
2. Using an ohmmeter, measure secondary resistance between terminal "A" and coil tower. See Fig 2 . Resistance should be as specified. See IGNITION COIL RESISTANCE  table. If resistance is not as specified, replace distributor.
