No, the screw will not come in contact with the other point no matter how it is adjusted. I thought about two fixes; either install a single pole toggle switch near the controls that connects the two points.... or put two nuts, tightened against each other at the end of the screw, that would then come in contact with the lug you worked on. Of course, I would have to use a dremel with a wire brush to expose some of the metal from that point you coated with sealant.
I'm fairly resourceful..... what would you suggest?
For what it's worth, I again say huge thanks to you for all your (and Ed's) help. I now have spark and sincerely appreciate a total stranger helping me out the way you have. For all the negative things going on in this world today, I can't tell you how much your kind gesture encourages me. It just might mean more than you understand.
