Ignition Cable: Testing and Inspection

INSPECTION OF HIGH-TENSION CORDS





1. CAREFULLY REMOVE HIGH-TENSION CORDS BY THEIR RUBBER BOOTS FROM SPARK PLUGS

CAUTION: Pulling on or bending the cords may damage the conductor inside.

2. INSPECT HIGH-TENSION CORD RESISTANCE





Using an ohmmeter, measure the resistance without disconnecting the cap.

Maximum resistance: 25 kOhms per cord

If resistance is more than maximum, check the terminals. Replace the high-tension cord and/or distributor cap if necessary.
