Ignition Cable: Testing and Inspection

SPARK PLUG CABLE TEST
1. Disconnect, one at a time, each of the spark plug cables while the engine is idling to check whether the engine's running performance changes or not.

CAUTION: Wear rubber gloves and rubber-soled shoes while working on the ignition system.

2. If the engine performance does not change, check the resistance of the spark plug cable, and check the spark plug itself.




SPARK PLUG CABLE RESISTANCE CHECK
Measure the resistance of the all spark plug leads.
1. Check cap and coating for cracks.
2. Measure resistance.

Limit: max. 22 k ohm
