I searched for this and apparently it hasn't been discussed in the last 365 days. Please remind me what two contacts I touch in the voltage regulator to go from 6v positive ground to 6v negative ground. I replaced my starter solenoid and now I have no power for lights or anything else. All the wires have been checked, connections good, no breaks in the battery wires,etc. Since I've lost power to the switch, the car won't start and none of the lights work. Very frustrating.

46 coupe you might have the wires on the solenoid on the wrong side, it has to be on the same side that the battery cable is connected to, you might have it hooked to the cable that goes to the starter, and only have electric when the starter is engaged any photo's was wondering why you want to change the polarity ? voltage regulator are what you need to change, the generator works either way, goumdiing the field wire for a split second, usually works, should have a slight spark you should invest it a repair manual, to save you time and parts, hope this helps 37Ragtopman, Maine

Thanks for responding. I'll try to get pics later today. I connected the new solenoid the same way the old one was. Thinking the new one might be faulty, I reinstalled the old one. I get the same results with both. I have a negative ground set up. So the positive battery cable goes to the closest terminal on the solenoid. The starter cable goes to the opposite large terminal and the small wire go to the small center terminal. I have power at the end of the postive cable but when connected to the solenoid terminal I get no reading on my meter. I have readings on my other large terminal and the small terminal. This has happened on both solenoids . Everything worked on the car prior to this. Your help is appreciated. I'll wait for your response before proceeding.

There are solenoids that use different wiring. They are not all the same internally.

Here are a couple of pics showing what's hooked up. I would think that the repro solenoid would be the same inside as the original for the car in question. As it is the original one isn't working now either and I don't know what changed. That's why I asked about polarity

Your solenoid is not wired correctly. The connectors from the loom should be connected to the side that the battery cable is connected to. With a Ford type solenoid, the battery cable connects to the driver's side of the solenoid along with the wires from the loom. The starter cable goes on the passenger side of the solenoid. The starter button connects to the center terminal. The solenoid coil gets the hot side connection from the left side of the solenoid and the grounded side of the coil from the center tap. When the solenoid is connected correctly, the center terminal should have 6 volts until the starter button is depressed. Tom

Hi Tom I'll change the connections. I don't understand why everything worked with the old solenoid hooked up as shown. I don't know if there is enough wire in the loom to reach the opposite side.. You did see that the car is now on negative , not positive ground. If on positive ground all the wires fit as you stated. If the wires don't reach I'll try turning the solenoid upside down. I'll wait for your further input. Thanks Brad

46 coupe What I see in the photo, that the main electric wiring is on the wrong it should be connected to the same side as the battery terminal on the solinoid so it supplys elect to the rest of the car, why would you change the polarity, it is not needed and cause many problems.,??? All gauges will most likley not work correctly or not at all and might burn out,??? might read opposite coil will need not work 100% not unless you reverse the wiring on it,, you should invest in a repair manual for you investment, this would be a great help my 2 cents 37Ragtopman

Hello, I have the shop manual the club sells plus a shop manual for the 1939-48 Ford and Mercury. I did not refer to them because the car had been working with this wire setup since I bought it in 2015. Did you read my post to Tom ? I just hope you or he can answer my question. I will reverse the set up as you all have said. I'm just curiouos as to why it worked before. Thanks to you all I should have it running tomorrow as I can't get to it today.

short answer: swap the battery and starter cables, I don't know how it could have worked wired this way. You need to read my complete post until you understand it. Reversing polarity may require a new coil as well as polarizing the generator. Tom This message was edited by TomO on 6-21-22 @ 6:06 PM

I was wondering if the battery is new, or if it is old and was dead and charged, it might have been charged in reverise, so the car would have worked before, it would have to be completely drained and recharge backwards, just a thought, my 2 cents 37Ragtopman

The battery is four years old showing a charge of 6.3 volts. I finally got time to switch the wires as suggested and I got lights. Tried the starter and heard a pop like a short makes. I’ll check the starter when I can get the car lifted. I might have to switch the wires there as well? I haven’t touched the regulator to do the polarity yet.

There is only 1 cable going to the starter. It comes from the passenger side of the solenoid. Check it for bare spots and at least 1/2" clearance to any metal parts. Can you post another photo of the wiring of the solenoid and the cable going to the starter? Tom

I've attached pics of the solenoid connections and the starter connection. I was thinking of the other connection on top of the starter. I don't see any bare wire or that any of them are too close where an arc would occur

Do you have a cable connected to the top brass bolt on the starter? I cannot tell from the photo. Where is the other end of the cable connected to the mounting bolt connected? Normally the starter just has one cable coming from the solenoid to the brass bolt on top of the starter. The Grounding of the starter motor is accomplished through the mounting face of the starter.

As of now the negative battery cable is attached to the starter face as shown in the picture. The cable attached to the top of the starter is attached to the driver’s side of the solenoid. That sure doesn’t sound right. FYI. When I got the car and purchased the restoration guide book, I noticed that the starter was painted green which means that it was for a 6 cylinder engine. Could that have anything to do with the problems I’m having? I’ll hold off moving the negative cable to the top of the starter until I hear from you or another member.

The cable going from the NEG battery terminal to the case of the starter is providing the ground for the system. Moving it to the top of the starter would cause a short circuit. I would not change any wiring unless you want to go back to POS ground. I suggest that you find a reliable mechanic and have him diagnose and repair your problem. It will be repaired faster that trying to get help over the internet. Tom

Leaving the wiring as is, the starter should work. Possibly the starter is the problem. It had made a weird noise and then just clicked afterward. It was after that I checked and replaced the solenoid. Thanks to you and everyone else who has offered help on this project.
