Ignition Cable: Testing and Inspection





- Remove high-tension cord at ignition coil while gripping its cap.
- Remove distributor cap installed with high-tension cords.
- Remove high-tension cord clamp from cylinder head cover.
- Pull out high-tension cords from spark plugs while gripping each cap.

CAUTION:
- Removal of high-tension cords together with clamps will be recommended so as not to damage their inside wire (resistive conductor).
- For the same reason, pull out each connection by gripping cap portion.





- Measure resistance of high-tension cord by using ohmmeter.

High-tension cord resistance: 10 - 22 k ohms/m (3.0 - 6.7 k ohms/ft)

- If resistance exceeds specification, inspect distributor terminal and replace high-tension cord(s) and/or distributor cap as required.

CAUTION:
- Never attempt to use metal conductor high-tension cords as replacing parts.
- Insert each cap portion fully when installing high-tension cords.
