delco Remy generator on an F-20

[SDE]

The tag has a number 948R32 874 on it. The wires are loose and in bad shape. Being that it is a 1939 model, will it be a six volt generator? A couple of years ago, my BIL gave me a generator from an Allis Chambers WD 45 that I think is a six volt and it may be in better condition. If both are six volts, can I use the better one without any problems?
Thank you

Go for it.

If you can get that old generator to a starter/generator shop they can make it new again. They are rather simple to build needing only a few parts to make a complete rebuild. I would not use the Alis generator since pulley and mounting bracket locations will not match up.

All depends on if you want to keep it original fixing the old one mite need the Armature rewound or the field coils could be shot. Most of the time cleaning the comutator new brushes and maybe bearing and or bushing could be like new again.
