Thread: GM 1 wire Alt. with a Ford voltage regulator

Tweet

Hello. I have a wiring diagram showing Fords electrical system, and am now considering going with the GM one wire alternator. Using the Ford voltage regulator, can someone tell me how to wire it? The regulator has 4 contacts; I, A, S, F for ignition, alternator, stator, and field. I also do not have the GM alternator in front of me, so could someone suggest the way to hook it up?

Thanks for any help!

You do realize that a GM one wire alternator has an internal regulator, dont you?

Here is Powermaster's Q&A page:

The first question is about hooking up a one wire alternator.

You will not need to use your Ford regulator.

Yeah i was gonna say the same thing, isnt that the reason people use a one wire alternator

Yep, they're right. You can remove the regulator and all that related wiring, and simply run a #10 wire from the batt or + post on the alternator to the positive battery terminal. That's it. No switch or anything needed.

By the way, this is a pretty easy wiring diagram to draw.

Yeah, even I can do this one.

This is truly a "painless wiring" diagram....if you get the "connection"

I've contemplated doing a one wire change then someone sent me this article - anyone care to have some imput to help me decide.

once there read the right up in the tech. area about 1 vs. 3 wire hok up.

You are overthinking your decision. Put a one wire on it and get it done. I ran one wire on my roadster for 7 or 8 years of daily driving, have had one on my Jeep for 3 or 4 years, and am going to install one on both of the projects now in my shop, and probably every one to follow. Already have the one sitting ready to go on the T bucket.

They are simple to install and you don't have to worry about the added component (regulator) and where to mount it. Plus it eliminates a lot of extra wires.

JMO,

I got thru two pages before I got tired of the implicit ego trip of the author.
May be great for the EE techies, but unnecessary in the real world.

Don't turn a 1 wire hook up into a science fair project. The GM single wire alternator, as Robot and others said, just bolts on and hooks up as illustrated...........

Pretty common sense approach to the differences in the two systems and why a 3 wire hook up makes better sense unless of course you are satisfied with a somewhat compromised electrical system. IMHO that equates to putting a 300+ hp engine in front of an early Ford drive train and expecting it to last.

Alright- I figured it was more simple than the three wire hook-up, but I didnt know it was that simple. I didnt realize it would totally eliminate the voltage regulator.

Thanks,
Greg
