This is a tool I made years ago but haven't used in a while. I used it a few days ago to test the ignition wire on my son's ATV. Just plug the ignition wire on to the end of the spark plug an clamp the tool to the engine to ground it. Crank the engine and if the plug "sparks" the wire is good. His did so it was on to checking all of the kill switches.
This is a common homemade tool that I'm sure many of you have made. I have a spare spark plug for various cars so there is usually no need to remove one from the engine I am testing.

I can't even count how many times I've tried to test for spark by holding the plug by hand to some part of the engine head. This is so common sense I'm kicking myself. And I have all the parts in the garage to make this. A new tool is about to enter my tool box. Thanks for posting.
