generator value ie 12vt===6 vt?

RalphWD45 · Jan 11, 2014

Sitting here watching the boob tube, and made up my mind to finally get the charging system working on my 52 B, so I can install some headlights on it. I have been charging a 12 vt battery every 1 to 2 months, since 1998 when I bought it, and overhauled the engine. It uses a magneto, and only the starter uses juice. It has a delco generator on it, wearing a large 3 wire regulator that I have been using for a belt tightner. My question is, will either the genny or reg, have 6 volt, or 12 volt stamped on it, so I can know what the previous owner used? I want to go over to the farm tomarrow, and take the generator off to inspect.

If the data plate is not there, since you are going to take it off, take it to your local parts store that tests generators, they can tell you. You might want to have it tested anyway.

start the tractor, ground the "F" terminal. THen take a volt meter and put across the "A" and "F" terminals and see if it has any output. Since there is no battery or regulator, a 6 volt generator will put out about 12 volts and a 12 volt unit will put out 24 volts (approx). This will be running wide open, no regulation at all. If the generator works, then you can get a regulator to control it.

A regulator will generally be marked.
The original generator on them was 6V, three brush. The third brush being adjustable, to adjust output, since the only other control was the hi-lo charge/light switch.
AC never, to my knowledge installed a regulator on a three brush generator, but MF did. Unfortunately the three brush gen. was available in 12V also, and looked identical to the 6V. All that to say if you have a two brush gen., it's more likely you already have a 12V.
Concerned about the closeness of the steering arm on my C, I put a two brush gen. from a D series tractor, along with a VR on there, and it works great.

Thanks guys! I found it today, and it had 12 vt , stamped in the regulator base metal. That small writing is very hard for me to see, even with my new glasses. I would like to blame it on excess paint, but really don't believe, that it's the problem. They just don't make glasses like they used to.
