Ignition Coil: Testing and Inspection

Inspect Ignition Coil
1. Measure the primary coil resistance between terminals 1-2 and 1-3.




Measure the primary coil resistance between terminals 1-4, 2-4 and 3-4.





Standard value :
0.58Ohms ± 10% (2.0)
0.96Ohms ± 10% (2.7)


2. Measure the secondary coil 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 :
8.8kOhms ± 15% (2.0)
12.5kOhms ± 15% (2.7)


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




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