EOD, lol, you're confusing me now.

I meant the little relay he remove has a bad coil, not the ign coil. I think the reason the ign coil reads short to gnd is because it shares the same power feed. Like, if you took the (+) wire off the car battery abd pressed it to chasis....every item in the car would read as shorted too. His relay coil (guessing) is shorted and it's also making the ign coil appear that it gies the gnd.

The reason I don't think it's the contacts in the relay is because they're normally open with no other "normally closed" contacts. Even if they welded together they'd only "turn on" a particular circuit prematurely.

Am I doing this wrong?
If they fall apart inside it could cause a short between any two or more pins, I have seen this happen a few times.
