I know everyone says "Dont pull a plug wire without grounding it somehow"
but I have never had a problem or caused anything else to fail doing it this way.
EVER, and it makes it really easy to find the cylinder that's not firing.

that's always fun , ive been shocked more times than I can count lol, but it works

make sure to use insulated needle nose or whatever
