Wiring a voltage regulator
Does anyone have an illustration to how to wire a flathead 8ba 6volt voltage regulator? Thank you in advance and if someone can walk me on how to polarize it.

Re: Wiring a voltage regulator
Here is a quick picture, last couple I've bought were like this and have instructions right on it:

Re: Wiring a voltage regulator
good resource. just need to pop the field on the regulator. If wired right.

Re: Wiring a voltage regulator
I have one more question I installed wires to regulator as shown and polarized it. With headlights off vehicle will stay on if I disconnect negative telling me the generator is doing something but if I turn on the headlights the engine wants to die if I disconnect the ground is that normal for 6 volt system doesn’t seem right to me

Re: Wiring a voltage regulator
You are probably not putting out enough amperage at idle to feed the headlights and the ignition. Does the car have an ammeter?

Re: Wiring a voltage regulator
You should see a difference on the ammeter between headlights on and headlights off. Think you are close to maxing out the generator at idle with the lights on. When driving the battery provides some reserve, but if you let it set and idle with the lights on the battery is going to lose the battle.

Re: Wiring a voltage regulator
Ok so I looked and in the back of the 39 ford cluster there is pins or anything to hook up the original ammeter I’m wondering how it works. So I checked everything had the generator rebuilt and now I’m suspecting it’s the voltage regulator what is a good way to test to to make sure I’m not just replacing it for nothing?sooooooo after looking I have a loop style ammeter that’s not hooked up but I’m sure I can run it with out it as long as it’s charging I’m almost sure it’s my voltage regulator just want to make sure before changing it

Re: Wiring a voltage regulator
39 ammeter would just be a loop through wire. Main power dash feed. If you loop it the wrong way the meter runs backwards.
It can be a bit of a wives tale that you can remove the battery out of the system and the car will run on these "modern fords". With a regulator you could run a voltmeter. . Last edited by Tinker; 10-15-2019 at 11:51 PM. |

Re: Wiring a voltage regulator
Run the yellow wire through the ammeter loop. ( you may have to reverse the direction of the yellow wire to have the ammeter show a charge with the engiine running - if I recall the yellow wire runs through the loop from the bottom and then to the circuit breake) You may have to close the eye terminal some to get it through the loop and then reopen the terminal to reconnect to the circuit breaker (or fuse?). If you have a fuse, put a circuit breaker in place of the fuse. Also connect your test voltmeter to the battery and rev the engine to at least 2000 to see if the voltmeter shows about 7.2 volts. The ammeter will tell you what the generator and ammeter are doing. I have a 38 that I installed a circuit breaker - a fuse will blow and then no lights!!!!!! Ford went to circuit breaker about 39 or 40, not sure. But get a circuit breaker installed!!!

Re: Wiring a voltage regulator
I would start by checking the voltage at the B terminal on the voltage regulator and at the (-) battery post. It should be somewhere in the 7.2-7.4 voltage range. BUT, the generator is not going to be capable of that output at idle!
