The solenoid with only one small terminal connects to the wire to the starter button which furnishes a ground when pushed. This ground is achieved thru the clips on the button mounting to the dash. If you have a solenoid with two small terminals, they are connected to each end of the solenoid internal coil which activates the switch. These "universal" solenoids were designed to allow the unit to be used as a replacement to some cars, such as old Fords, and other makes which supplied power to the unit, with the other terminal grounded and power from the button or switch. I recently helped a friend who called our shop with a dilemma. He had replaced the solenoid, but now some parts of the car, such as the gauges were not working. The fix was simple. The solenoid large terminals connect to the battery and the other to the starter motor only. They had connected the wires, other than the one to the button, to the wrong side when they installed the new solenoid, and reconnecting to the battery side solved the problem.

I may have missed something , you have 6volt pos grd and you have one terminal on the starter button: thats simple you bought the wrong solenoid. Correct solenoid works by grounding the single terminal & dash button gives it that ground... Napa has those.

Hey Dustbowl---- Didn't your grade school teacher ever tell you "there is no such thing as a dumb question". You didn't waste anybody's time with your inquiry. All the regular contributors to this Forum have dealt with PLENTY of "dumb questions" with their cars. This Forum is to help members with their questions, whether they have restored 1 car or 50. If you got any more questions about your 36 - feel free to ask. We are all here to help. Stay warm. Tom

I will - 15 minutes later - answer my own question. Answer is my description is not correct. My problem is simply that I bought the wrong solenoid (one for use when ignition key starts car and a separate starter button is not used) instead of one for use with starter button. So you can ignore my whole entry - apologies for wasting your time.

Maybe this 1937 Wiring Schematic will help you > http://vanpeltsales.com/FH_web/FH_images/FH_electrical-pics/Flathead_Electrical_wiring1937.jpg

My 1936 was restored with a starter solenoid rather than old floor button, as I imagine most old Fords now are. My solenoid failed and I am replacing it. The solenoid supplier instruction implies that a two pole starter button is used with one pole connected to the small pole on the solenoid and the other to the "hot" side of the battery (negative in the case of my positive ground set up). But my car has only a one pole starter button with wire connected to small pole on the solenoid. When the button is pushed, the wire is grounded. Wiring this way requires the cables to the two big poles on the solenoid to be reversed compared to the two pole button set up. My question is whether my descriptions above are correct or not (presuming you can understand my text)? And, more importantly, are there any disadvantages to the one pole starter button method?
