What 12V. Generator will work on my "C" ? I am staying with a generator system and want to stay as original looking as possible. Can't think of one that has the regulator mounted on it that was used in auto application. And there is not a tractor yard nearby to scrounge around in. I would like to order one but not sure what to ask for one off of. What have any of you guys used?

Try Classic Generator for 12V generator conversions. CLASSICGEN@aol.com They are in Texas, and the owner's name is Kenneth.

Thanks guys! I like the idea of hiding the reg. in the toolbox and reusing the cutout as a dummy! I need to do some rewiring anyway so that is a good approach. Just couldn't see having that big reg hanging off the generator. I will have to compare the cost of a rewind to a replacement. Wonder what the output of a rewound generator would be?

A "small" 12 volt generator was normally about 20 amps. By the time they started going to 12 volts (tractors and trucks) the vehicles were being equipped wiht lights and radios and 20 amps was about standard. Some had 25 amps. In comparison, your 6 volt is probably 8-10 amps.

My "B" had the generator rewound to 12 volt negative ground before i bought it. I bought a voltage regulator at Auto Zone for a '59 chevy pickup for $20. You might compare the cost of the Delco generator off the '59 chevy to cost of rewind. They look about the same. If you go to 12 volts, i would definitly try to get a negative ground system also.

CJ- a little more info-- The original regulator on the generator is actually a voltage cutout that connects to the "A" terminal. The "F" terminal goes to the headlight switch and is grounded directly to get 10 amp charge, or goes thru a resistor to drop the charge to 3 amps. The newer generators are 20 or 25 amps and therefor usually have a "voltage regulator" with 3 terminals on them. Quite a bit bigger than the small cutout relay on your generator. If you try to use the cutout with the big generator you would be getting max current (25 amps)with the lights on and lower amps (maybe 10) with the lights off. This is by using the resistor head light switch. It would look original, but as you can see you would probably be overcharging and cook you battery in a few months time. That is why they went to the newer voltage regulators that have the "A", "F", and a "B" battery terminal on them. The "F" coil in the regulator takes the place of the head light resistor and does a much better job of regulating the current than the fixed head light resistor.--hope this helps you decide. I did as Dewey said and mounted a real regulator under the gas tank where it is hidded. You could always leave the cutout on the generator for looks, but no wires.

CJ,
If you stay with the generator system, the regulator can be mounted in the tool box under the fuel tank to keep a more origional look. The C had a cutout relay mounted on a 6 volt three brush generator that used a resister on the light switch to regulate charging rate. If you change to a 12 volt two brush generator, then you need a regulator. The regulator takes the place of the cut out relay and light switch resister. Duey

Take your generator to a good electrical shop. They can rewind it for 12v and you'll be in business. I'm not sure if you'll have to replace the regulator or not; some people say you do, some say you don't.

Oh - one other thing. If you have lights on your C, you'll have to replace the bulbs with 12v bulbs, and if you have a distributor-type ignition, you'll need to put a ballast resistor in-line before the coil to reduce the voltage to 6v. Otherwise, you'll destroy the coil and fry the points like nobody's business.

i've got a 12v gen off of an e gleaner. i'm at work right now so i can't too specific, but maybe that'll get you started.
