The Ford Barn - View Single Post - Generator not charging

The generator will produce whatever voltage is required by the battery.
The cutout shown is original. Stampings are ~1930, I believe; mounting pads aren't slotted.
Generator must exceed battery voltage in order to operate the cutout.
Two types of diode cutouts - positive or negative ground, not voltage dependent.

Ordinarily you could adjust the third brush to increase the output, but your generator has been modified internally, or may not be for model A. You'll have to open it up to see what you have.
