which voltage regulator?

Postby cabinetman » Fri Apr 15, 2022 1:48 pm

Hi all. I appreciate the info on the carbs provided by five fellas. I'm going to try to rebuild this one. I've got a lot of experience with old carbs so am not expecting any issues.

Now I'm faced with rewiring my 1940 A. It has a generator but no belt. I've also found an old Chrysler 6 volt regulator, without a cover, screwed to the body and it's not usable. IT's also not original to be sure. I have installed a new battery in a new battery box (very spiffy!) and rewired it correctly (red to ground) and can easily start the tractor as long as the carb cooperates.

I also have installed a set of lights on it and am going to install the rotary light switch below the ammeter.

The question I have is WHICH regulator am I supposed to use? The original one looks like it had two or three contacts. The one I threw away had four. Steiner's has one for $20 or $125. I also own the repro manuals and service books for this tractor but I'm at a loss to figure out which one is correct. Can any of you all out there point me in the right direction? One regulator screws onto the generator. Is this what I need?

Very much appreciated.

Please all, have a safe and enjoyable Easter hopefully with family and friends.

You need a regulator that matches your generator. Since the regulator had been swapped out, maybe the generator has too. If you have the original generator, it is a 3-brush unit with an adjustable third brush. If it still has the Delco ID tag, what number is on it? The original was probably 1101355. It would have had a cut-out mounted on top of the generator. You should still be able to find the 2 screw holes for mounting it, although they may be full of paint or trash. The top-mounted cut-out often gets replaced with a regulator that has a special base for mounting in the original cut-out location.

If you don't have 1101355, you need it ID what you do have. Pictures would help.

The voltage regulator was toast so I'm starting from the beginning although it, too said "Chrysler" but it could not have been original but cobbled together. I'm still learning to use google photos and importing them into posts. sorry!

Just figured it out. Expand the picture in photos, select share, select "create link" and copy the link like above. Not too bad.

Let's try a short video. Easter!

That generator matches the regulator. It was original to a lot of early 1950s Chrysler products. Here is a new regulaotr that matches:

I would probably look for an original type Delco generator or consider changing to 12-volts with a newer style alternator.

Why bother with some image host, when you can just post them here?

Opinion. 12 volt single wire alternator. Cheaper than a voltage regulator and generator repairs.
I have an excuse. CRS.

First I'm going to check out that voltage regulator because I've got a brand new 6 volt batter and box installed. If that doesn't pan out then I'm going to consider going to an alternator if for no other reason than simplicity. I used the "url" method because the photos came off my google photos account on my phone. I'm making some changes there, however, and will just post 'em up in the future.

Don't spend any more money until you have the voltage regulator and the generator tested. Some shops can test them.
