push button start ques.

[updated:LAST EDITED ON 13-Nov-02 AT 03:12 PM (EST)]it isn't really all that hard, i had it done on my 76 i used to drive.
you need a pushbutton (of course) and some wire,although on a standard you will have to hold the clutch in... ask me how i know this.

Take the wire off the S terminal on your solenoid, and attach a wire to this terminal securely, and run the wire back into the cab to one side of the push button.

Take another wire and attach it to the hot side of the battery and run it back into the cab to the other side of said button.

Turn the ignition switch to the run position and push the button, it should start up.

Thats how i had it done on my old ride, but my memory is a little fuzzy...

hope it helps!

I tried that method and it does not work on an 85-250

But, It will fire-up if I short across the starter solenoid.

It should have worked.

you need a wire to go from the battery to the cab and attached to one terminal of the push button.
The other terminal of the push button goes to the S terminal of the of the Starter solenoid.

You are essentially by-passing the neutral safety switch so make sure you are in neutral or park with the key in the ON position.

WHEN YOU REFER TO THE S TERMINAL what terminal are you referring to ?
I have 1 ----1/2" lugs on each side of the solenoid and 1 that has a I THAT IS APPX 1/4 "nothing that says S.

Look on the solenoid for the letter S right above a small terminal.

In this photo the connector has been removed.

That's weird.If there is only One small terminal, it should be an S not an I.
In some years they got rid of the I.

Here is a copy of the wiring diagram.

sO IS WHAT THIS MEANS, someone has changed the starter solenoid without me knowing about it. Because it has only 1 small terminal post and it is marked with the letter I . But there is only 1 wire there and it is red.

The starter relays changed in the 80's, I do not remember what year, to only 1 terminal and the wiring changed a little to accomodate this 1 terminal. The voltage that goes to I terminal also feeds the ignition module with the "starting" signal.
So if you disconnect the wire and put in a push button circuit the igniton module isnt getting "starting" voltage.
You can try leaving the old wire on the terminal as well as adding a push button, or tap into the circuit at the neutral safety switch. If you do the latter then you can retain the neutral safety starting function.
The older trucks had two terminals 1 to close the relay (S) and another that fed the ignition (I).
