Yeah, you hear more stories of the 6a box that gets passed on to friend to friend.
I think the type of coil I was using and the idea of having it grounded is pooh, obviously give the a coil a choice to chose a path of less resistance is not a good idea.
Example; a Tee on a water faucet with 2 same diameter sized hoses, one 5 ft. long and one 50ft. long. Which hose will get less water at the end?

Three arc slits, it was also firing at the base of the corner. This coil has a 1/8 stud in it and the plug wire clip would go over the stud so you cant get deep into the insulator. Piss poor design unlike the canister coil

The ol school canister type is oil cooled and it "does not need a ground" other then the black wire (-) and orange (+) from the box.
Makes total sense doesn't it? NOT!
