Ignition Cable: Testing and Inspection

Spark Plug Wire Inspection

Spark plug wire integrity is vital for proper engine operation. A thorough inspection will be necessary to accurately identify conditions that may affect engine operation. Inspect for the following conditions:

1. Correct routing of the spark plug wires-Incorrect routing may cause cross-firing.

2. Any signs of cracks or splits in the wires.

3. Inspect each boot for the following conditions:

^ Tearing

^ Piercing

^ Arcing

^ Carbon tracking

^ Corroded terminal

If corrosion, carbon tracking or arcing are indicated on a spark plug wire boot or on a terminal, replace the wire and the component connected to the wire.
