Ignition Coil: Testing and Inspection

INSPECT IGNITION COIL




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) for the ignition coil, and between terminals 2 and 4 (the coils at the No.2 and No.5 cylinder sides), and between terminals 2 and 3 (the coils at the No.1 and No.4 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% (k Ohm)

CAUTION: When measuring the resistance of the secondary coil, be sure to disconnect the connector of the ignition coil
