Coil Testing

1. Measurement of the primary coil resistance.




2. Measure the resistance between connector terminals 3 and 2 (the coils at the No.1 and No.4 cylinder sides) of the ignition coil, and between terminals 3 and 1 (the coils at the No.2 and No.3 cylinder sides).
Standard value : 0.77 - 0.95 Ohms
3. Measurement of the secondary coil resistance.




4. Measure the resistance between the high-voltage terminal for the No.1 and No.4 cylinders, and between the high-voltage terminals for the No.2 and No.3 cylinders.
Standard value : 10.3 - 13.9 K Ohms


CAUTION: Be sure, when measuring the resistance of the secondary coil, to disconnect the connector of the ignition coil.
