Re: If I have a wiring error, I simply can’t find it…

You are an EE and you are asking us? Sorry, I couldn’t help myself. All in fun, no disrespect intended.

The kill switch, when turned "off", connects the two black wires that lead to the points together. When those two black wires are connected together it will lose spark on both cylinders. You could strip out all the other wires and that would still be so. If it is wired correctly and wires are all intact it will work.

They made many thousands of them that way. So I don’t know what else to say.
