Hi ford folks, can anyone help me to workout how to wire up the starter push button on my 1952 ford f1. The truck must of had the ignition switch replaced at some time, as the switch that is fitted has four posts and the original switch only had three posts. I can wire the switch so that the truck will start with the ignition key , but I cannot find out how to make it start with the ignition switch turned on and pushing the starter button. The starter button has two wires coming of it, where do these connect to make it work ?.
Many thanks.

one wire is from the ignition switch "on" and the other wire go's to the start soleniod on the firewall.

 

Thanks for the reply, the wire from the button to the ignition switch is it connected to the acc post?

Should be the one for run only not Acc, otherwise the starter could be engaged when in accessory

 

Okay thanks for your help.

The original Ford wiring has the starter button Hot all the time. "May" be a safety concern. It can be fed right off the 15 amp circuit breaker right next to the button.

 

Thanks for the info on the circuit breaker. Can either of the two wires be used for the power and the solinoid ?

Yes.

If you have kids, Kurt's warning is worth thinking about. Kids love to push buttons!

 

Thanks for the reply. Will have a look at it over the weekend. Will post update.

the key switch on start mode is hot all the time also. So even if the engine is running and you turn the switch from run to start, the starter will engage. Same thing if you push the button while it is running.

 

In simplest of terms, you want to cut the "ST" (starter) wire from the existing 4-position switch and connect it to one side of the new start pushbutton. The other side of the start pushbutton gets connected to "battery". Since I don't know whether you have 6v/12v or +/- ground system, I have left the markings on this generic diagram as is.

 

The above diagram will work in the simplest form. Alternatively, this setup requires the key to be on in order for the Push Button to work.
