What screw is on the back of the generator to adjust the third brush. I am confused by the directions and not familiar with this type of generator. Do you move the brush in to the motor to increase amperage or away from the motor? Thanks Paul

One other thought, as you’ve changed the battery , has the new battery been installed correctly, all Chevrolets are negative ground, and has you have a history with early fords, may have overlooked this fact. ( model A fords are positive ground, even though model T fords were negative ground!!)

Once you have checked battery polarity is correct, the generator can be polarised by a short length of wire , momentarily touching both sides of the cutout mounted on the top of the generator.
