Ignition Coil: Description and Operation

GENERAL INFORMATION




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% (ohm)




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% (kohm)

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