INSPECTION & TESTING




WARNING
On 1980 and later models, DO NOT pull the wires from the distributor cap. They must be released from inside the cap.

Visually inspect the spark plug cables for burns, cuts, or breaks in the insulation. Check the spark plug boots and the nipples on the distributor cap and coil. Replace any damaged wiring. If no physical damage is obvious, the wires can be checked with an ohmmeter for excessive resistance.

REMOVAL & INSTALLATION




WARNING
Replace the cables one at a time to avoid confusion.

  1. Unplug the wire from the spark plug.
  2.  
  3. On 1978-79 models, unplug the wire from the distributor cap. On later models, remove the distributor cap and disengage the retaining tabs securing the wire to the cap.
  4.  

To install:

  1. Install the boot firmly over the spark plug and distributor cap terminal. Route the wire exactly the same as the original.
  2.  
  3. Repeat the process for each cable.
