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 distributor cap.

Maximum resistance: 25 k ohms per cord

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