Ignition Coil: Description and Operation

1. Measurement of the primary coil resistance
Measure the resistance between connector terminals 1 and 2 (the coils at the No. 3 and No. 6 cylinder sides) of the ignition coil, and between terminals 1 and 3 (the coils at the No. 1 and No. 4 cylinder sides), and between terminals 1 and 4 (the coils at the No. 2 and No. 5 cylinder sides)

Standard value: 0.74 ± 10% (Ohms)




2. Measurement of the secondary coil resistance
Measure the resistance between the high-voltage terminal for the No. 3 and No. 6 cylinders, between the high-voltage terminals for the No. 1 and No. 4 cylinders and between the high-voltage terminals for the No. 2 and No. 5 cylinders.

Standard value: 13.3 ± 15% (kOhms)

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