Wiring for my Push Button Starter switch

Truck: 1955 F100
Starter Solenoid: 3 post
Ignition System: MSD Digital 6al

I have the 1 wire chrome push button starter switch from Midfifties. I just had the whole cab painted so for this button to work do i have to sand away the paint around the hole opening? I'm 99%sure i do but i want to double check here before i sand this area to metal.

You should have a 2-terminal starter button. If so, no, you don't need to sand. The switch closes the two contacts internally.

6 volt or 12 volt system? The one-wire switch simply provides a path to ground from the solenoid coil, which is normally hot on the 6 volt systems.

It is a 12v system wired negative ground. When i bought it the discription stated it will work with both a negative and positive ground. I might just go back to the stock 2 terminal button but i liked this burton because it was chrome.

You just have to ground the housing/mounting of the pushbutton...it's really not that big a deal, the button flange will cover the bare area.

When I converted my 50 F-3 to 12 volt neg. a few years ago, I bought a 12V starter solenoid for a 56 truck which is 12 volt neg ground like my 50 is now. Well, my one wire starter button failed to energize the solenoid. So, I put back in the 6 volt original starter solenoid and it has been starting ever since. By the way I think the starter button gets its ground from the clip or whatever holds it into the dash from behind.

Maybe that helps. Patrick
