I am switching my 47 from 6 volt positive ground to a 12 volt negative ground. I put on a solenoid for a 56 Ford and the original starter button is a single wire connection and it grounds to the dash when depressed. I can’t figure this out and can’t get it to work. Should I get a two wire starter button from a 52 Ford truck? Obviously I’m weak on auto electrics so any help would be appreciated. Thanks.

So, this a common question when folks ask about switching from 6 volts to 12 volts. Why are you doing it? John

It's possible that you have the solenoid wired incorrectly. The solenoid should be mounted with the button or the end closest to the cables at the bottom. If the starter and battery cables are reversed at the solenoid, it won't work. The cable from the battery should be attached to the solenoid on the terminal closest to the engine or to the right side. The cable to the starter should be attached to the terminal closest to the fender or to the left side. The starter button wire attaches to the small terminal in the middle of the solenoid. If the solenoid is wired correctly, and still doesn't work, attach a wire to the middle terminal and ground it. If the solenoid works then the starter button is bad. Ken

Your best solution is probably to buy this solenoid: https://www.vintageautogarage.com/1937-56-Ford-Mercury-Lincoln-Start-Solenoid-12V-p/7-1013.htm?gclid=CjwKCAjwjLD4BRAiEiwAg5NBFnvgxu2FWTk2qYJeuOZVn3wSI_4ahP-XbsEUeeM_GgJJHtDU8TuesRoCFlIQAvD_BwE Or you could just use you original solenoid. It should work fine for a long time, unless you crank the engine for long times, causing it to overheat.

If you have two small terminals on the solenoid, you have a "universal" replacement. The terminals connect to the ends of the coil that pull the armature. Ground one and apply battery to the other. If it clicks, it is OK. The stock circuit for your '47 has a dash button that furnishes ground, unless the car has been rewired, and one of the terminals goes to that button, and the other to the battery side of the solenoid.
