plug wire+ boot+ gap  distance

May I ask you to clarify? I’m guessing you want me to evaluate where the path of least resistance is in my system? If so:

Wire = 0.00

Boot = 0.00 (rubber, non-conductive)

Gap distance (nominal. Trying to get to 3/8 to 5/16)

Solder joint to laminate is much greater than that. So, in theory, the gap checker should fire long before the coil grounds out to the laminate. That still leaves the question of the other coil grounding to the mag plate.

Do I remember correctly that a motor should not be rotated without a plug installed to avoid damaging (don’t remember what)?

I was doing that when testing. Test #1, #2 wire was left without a plug in the wire. Vice-versa.

Thanks for the help!
