Spark Plug Wires

Print

Inspection & Testing



Using an ohmmeter, measure the resistance of the spark plug wire. Resistance should be a minimum of 250 ohms per inch (3000 ohms per foot) or a maximum of 1000 ohms per inch (12,000 ohms per foot). Replace any wires outside of specification.

Inspect the wires for cuts, cracks and abrasion. Replace as necessary.
