Voltage Regulator??
 

Anyone use a voltage regulator in their Model A?? If so what regulator and why? I am replacing the wiring harness and the awful wiring job on my 30 Coupe. It has a lot of stuff wired to a voltage regulator n the firewall and I’m wondering if that needs to be there.

What generator are you running, two brush or three?
How about a picture.

It sounds like you're using a later style 2 brush generator. If so, then a regulator needs to be mounted somewhere.

If you want to install an original type 3 brush generator then you don't need a regulator, just a cutout.

I use the Fun Projects voltage regulator that takes the place of the cut out . The original cut out doesn't give voltage regulation .

Three brush delco remy uses a 2 point regulator which functions like a cut out and the 2 brush uses the 3 point regulator. Tractors used the same set up and there are documents and videos on line that show how it connects.

How do you determine whether your generator is a two brush or three brush generator??

Re: Voltage Regulator??
 

Pull the band off the back end and you should be able to see.

I use Tom Wesenberg voltage reg, his is fool proof ,if the generator should go open circuit the voltage will remain low, not going into a self destruct high voltage runaway.

One post (ARM) on top - three brush. Two posts, (GEN,FIELD) - two brush.
