Now look at the wires under good lighting. This will often produce an arc from the wire to the screwdriver.
Then, run the tip of the screwdriver along the length of each wire and all around at the coil and plug boots. Of course, running the engine at idle doesn't exercise the ignition system very hard, so you can add something to the test by spraying the plug wire ends with clean water from a household spray bottle.Īnother test: With a jumper wire, ground the metal shank of a screwdriver that has a well-insulated handle. If you see little electrical arcs, or hear a snap-crack, there is high-voltage electrical leakage. Run the engine in near darkness, and then look and listen. The jackets may be damaged from the outside by abrasion caused by engine vibration (particularly at the plug-end boots), a hot engine compartment, spilled fluids or battery acid, multiple disconnections and reconnections for other service, or even a family of nesting rodents. Engine misfire often is caused by leaking spark plug wires, so visual inspection could reveal what's wrong. However, not everything calls for high-tech diagnostics and the latest scan tester. You've touched every sensor connection to see if it's on tight, you've even checked for trouble codes.
