If you were an AOMCI member, then these guys would tear you up even more. Ask me how I know this.

I was thinking about it last night and had come to a conclusion in my mind that, if not a weird switch, then the vacuum switch must have been connected with the mag wire on the center, insulated terminal and the wire coming from the kill switch, grounded at the vacuum switch, not connected to the other mag wire. That would make it so that, when you hit the switch, one set of points would be grounded but the other would be isolated. (Maybe you still want to scrutinize the ring terminal on the end of the mag wire, for a solid, reliable electrical connection.) But whatever. Water under the bridge. I’m glad it works; and thanks, actually, for the brain exercise. The most fun on this site in months!
