Generator adjustment

Looking for advice for adjusting thee 3rd brush on my generator 309cid 6 cyl Chrysler imperial marine engine 1928 specifically the lock screw and what direction to move. The 3rd brush to reduce the voltage output of the generator

Hi Tom, if your generator is working properly to reduce the output, you’ll move the third brush away from the output, brush where the wire comes out of the generator to the cut out. Typically viewed from the back of the generator, which is known as the Commutator end You would move the third brush clockwise. If you have a problem, please feel free to call. I’d be happy to walk you through the adjustment. Our number is 201-445-8685.


Once I get the boat out of storage and starting working on it, I may be giving you a call but thank you for your offer. Appreciate your help.
