Sounds good. Get some rest. I'm thinking that if your starter button has two leads, one of them should go to ground (it's not the original starter button?). But forget that for now and try the jumper wire tomorrow.

 

No. But there are similarities. A solenoid is an electro-mechanical device consisting of a coil and motor (slug) that produces linear motion from a magnetic field. In this case it would be used to push a Bendix drive to engage the flywheel. They are mounted piggyback on the starter motor. A relay is a switch that utilizes small voltage and current to switch large current (and sometimes voltage). Sometimes a relay is incorporated in the solenoid, but our trucks don't have that feature.

 

When you try the jumper tomorrow make sure your ignition switch is OFF, or just remove the red wire from the relay to be safe.

 

Kind of hard to jump into this because you are there and I am Here lol.......All Ford product are 6vt pos ground up to the end of 1955. Model T' neg ground. The ignition (hot) wire goes to the minus on coil and plus + goes to dist. points. Next I think i read hot wire from ign to push button. Thats wrong. Should be one wire on start
button going to solonoid or some call it relay. This is a ground. wire. So I would take that wire off solonoid and
use a jumper on that terminal to a ground any ground - motor should turn over. If not with same jumper touch it
to plus + on battery - if it turns over you got the wrong solonoid. Going back to if it turns over when grounded
but does not with push button then the push button is not grounded to dash or is no good. This button depends on its two spring clips grounded to the hole in the dash. clean file sand whatever but do make sure the solonoid has a good ground.plus body to engine ground. Trust me you have a simple problem, just try
these new crap boxes that come in here so called modern junk. Never fails for something of age to come in
our shop that got Bozos cutting pliers: Example we have a 1949 F8 always half turn starts the big bad Lincoln, lately no start -whack solonoid it starts whats that tell ya and button wire to solonoid is good: that mean sandpaper on solonoid mount and new screws..... thats how it works does this help?
sam Ya I know gotta fix the F8 when the heat wave goes south

"if it ain't got air brakes, I don't want it"

 

Directly to the solonoid terminal........................

 

 

 

 

 

 

 

The way this is wired there is voltage coming both ways to the start button. I don't think you want the right side (in the drawing) going to the ignition switch. It needs to go to ground.

 

My 51 start button only has 1 terminal and the body is grounded to the dash.
