Scott,
Thank you so much for posting a picture of your spark tester. I made one yesterday and it works great!!!
This is the coolest thing!
We have been able to troubleshoot a bad coil; separated it from the power pack and leads!
Success!!!!
Thank you, so much!

Do you happen to recall what size bolts those are?

Save me from experimenting and probably screwing up a wire spring. LOL

Thanks.

I used 1/4-20 carriage bolts, 5 1/2 inches long with the heads sanded down.
You can cut the heads totally off but I wanted to try to get a snug fit in the plug wires.
