I did a fair amount of research & didn't see this covered. Can I use a 4 post regulator with my generator, or do I have to use a stock style 3 post? My set up is a 12V positive ground 8ba that I'm wiring up now.

Thanks...

I always use a 56 Ford regulator and wire it as a negative ground system. (never saw a 12V positive ground system) Don't over complicate it. Forget about positive ground and just wire it like a negative ground 56 Ford using parts intended for a 56 Ford. Not parts for Imperials or Impalas....56 Fords.

Don't get intimidated just think 56 Ford. It will work and charge like a bitch if you make believe that you are working on a 56 Ford when you look it up in a book. It will need to be polarized like a 56 Ford which is different from how you polarize a GM car. Look it up.

Wow... that was a major brain fart. I meant Negative Ground, not positive ground.

So I guess '56 Ford was the first year of 12V then? And, it sounds like you recommend going with the typical 3 post VR and stay away from the later 4 post?

Yes VRs and their wiring need to match the generator that it was built for. 56-64 Ford will work just fine with Ford generators no matter what they are bolted to.

This is my crude wiring diagram that works for me.

Ha! Tommy... Thanks for the diagram... I saw some of your previous posting activity & one of your posts had the exact same vintage pic that I was looking at in a '67 auto book on generator diagrams! It sounds like I just need to get a different VR & I'll be on my way!
