HOW CAN I TEST SPARK PLUG WIRES?
i need to no if my spark plug wires are sending a spark how can i test them to see if they are working
the car is not running and it has new spark plugs and the spark plug wires are pretty new to but i need to no how to find out if they are working
The only thing that can really go wrong with a plug wire is a break in the insulation. The insulation (the rubber on the outside of the wire) keeps the electricity where it needs to be so it sparks on the inside of your engine, not someplace else before
