How do you adjust the voltage regulator?

I am still having regulator problems, where do I find the info on adjusting it?

You don't adjust it, you replace it.

I have tried 3 different regulators and still don't have one that works.

Pat:

The BIG questions are.........do you have the correct V/R....???

Is the V/R properly installed and wired...???

Voltage regulators are adjustable, but it's not for the novice.
Back in the day (50's) I adjusted many to suit my driving conditions or that of others.

We didn't have $$ to spend on new, unless absolutely necessary.
But I'm thinking you have a different problem, possibly a ground that isn't good or a misplaced wire, as you have installed 3 regulators and it still isn't working for you.
Have you checked that the wiring is correct leading to and from the regulator?
--on a generator, if the field terminal is grounded, it will produce full output and be
Unaffected by a voltage regulator
Possibly you have a bare wire causing this?

I tried one of those 4 wire VR's first: F,G,B,L terms. All it did was full charge.

I have another 4 wire with the G term on the bottom, It is the same as the 4 wire.

I now have a 3 wire F,B,G with a ground. The wiring is new, and is wired correctly. The SG was used as just a starter for some time, don't know how long.

When I hooked up the 3 wire VR, at first it would charge, and tehn go to full discharge. It acts like the points are sticking. I took the top off, and if you push the cutout down it will start to charge and then go to discharge. When I shut the motor off the SG is turning. I have to unplug the B term from the VR. With it running the Voltage/Current reply is moving up and down slowly. When I push the Cutout down the VC relay goes down and stays there, and into full discharge.

Is it possible that the SG is shorted? I tested it by spinning it with the key and grounding the F term, it did slow down like it is working, and it does charge, but the VR isn't controlling it.

The wiring is new and it is correctly wired. What I'm thinking is there is a short in the Generator Field winding, since it was used as just a starter. I have no idea how the SG was wired by the PO. I plan to pick up another SG this weekend.

I have been going over how this things works and am convinced since it's the only thing not replaced it has to be the problem.

why not swap the SG off your 149 for the 129 and see if it works before purchacing another SG?

I have it off, but the posts are rusted badly and it wasn't making good contact.

did you do a reverse polarity at the regulator before starting it? Its a forgoten part on some older thactors that need it done in order to charge right.
