Dummy me, deleted a photo I'd taken prior to un- wiring coil box switch to clean and polish up. Think I know, but is there such a thing as a wiring diagram?
Or, a photo? Most interested in centre wire?
See this thread from 2013: http://www.mtfca.com/discus/messages/331880/397207.html?1382935574
The center wire should go to the bottom strip in the coil box to supply the coils with voltage from either an accessory battery or the Ford magneto connected to each side contact.
Thanks Roger, I was able to do that ok with having a sample to check. My main interest is where that wire goes in the switch. I suspect to the lower plate that is under the plate moved by the key. Correct?
This is a picture from my 1914 coil box switch. It may have been original based on the disintegrating cloth wrapped wires. On mine, the center wire attaches to the bottom right terminal. The two bottom terminals are connected electrically, so it doesn't matter functionally. The other end is connected to the bottom strip in the box as Roger said above. Sorry about the dark picture, I never planned on it being on the Internet.
Thank you jay, that is what I thought, but needed to be sure and comfortable.
