Anyone know what brand, or where to get a ford starter solenoid with the button on the bottom for bumping the eng over?

Thanks,

jim

Leon, I think the ST 58 is for Negative ground only. ST 53 is the one for Positive ground. I found this out the hard way when NAPA thru the wrong one in the bag when I needed one (ST53) for positive ground on '49 PU. Of course I couldn't return it. The ST58 was made for some small Nash/AMC cars that were 6 Volt. 58 was made in Asia and 53 was made in Mexico with no ST number stamped on them only 6V, back in June 2020.

Make sure you take it out of gear before you push the button. Scare the crap out of you if you don't!
 
I think some make their connection when the small wire is negative, and the others when the small wire is positive. I'm no electrician, just my observation when testing them.
 
One of the handiest tools around my garage is the remote starter button, which clips to the terminals of the starter solenoid. Like to chank the engine while checking for a spark from coil or plug wire. Or running a compression test. Or testing for fuel pump output. Better than the solenoid with a button, because you can activate it from any place around the front end.
 
Doesn't the pull-in coil need the electrons flowing in the correct direction to make the magnetic action pull the correct way? If polarity reversed, wouldn't the coil try to pull the other way?

EDIT:
Just thought of something: My wash machine uses solenoid water valves, and its running on alternating current, electrons flowing both ways. So I guess a solenoid coil does not care about positive/negative.

6 or 12V? If 6V, I have a brand new Standard in the box that I can get the part number off of if you're interested. It has the starting button
 
I use an original ford unit, now on 12v neg ground, works fine. I did learn though, they need to be mounted so that gravity can not help hold the circuit closed or they will stick on occasionally.

Yeah, he "mechanic's button" goes on the bottom.
 
The starter solenoids we use in our old cars will certainly work for both negative ground or positive ground. Some types however have differing internal connections for different wiring hook ups. The two types shown in posts #2 & #3 are the early Ford type with the button which are normally mounted with the button underneath, but would work in any position. Pity some incorrect information has already been posted on here, Regards, Kevin.
 
Well, this is quite timely for me. About 5 minutes ago I had made up the battery cables and put a 12v battery (and negative grounded)in my newly fabricated battery tray. I had the solenoid with a button (looks like a repro style of original) mounted to the firewall. The small terminal on the solenoid is labled 'battery'. I jumpered a hot wire from the battery positive terminal to that small post and nothing. I then jumped a wire from the grounded chassis and off she spun. I know very little of electrons and such so it is all trial and error with me. I guess I will keep it this way.
 
GB, Yes all the early Ford V8 solenoids require the small terminal to be grounded through the starter button to the metal on the dash panel. Yours is correct for a Ford V8. There are many other types of wiring hook up solenoid types with different terminals. Regards, Kevin.
