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

The screw on the back plate is to loosen the clamp on the third brush. To access the
third brush , the metal cover band has to be removed, and then the third brush is pushed around the commutator by hand, anti clockwise to increase current and voltage and clockwise to reduce current and voltage, ( looking from the back of the generator).
