36 Ford 3 brush generator

[CWells]

Is the third brush on a three brush generator for a 36 Ford adjustable? 6 volt, positive ground with original style cutout.

Yes, it is adjustable. The third brush moves up and down. There is a procedure for the adjustment. See this thread > https://www.fordbarn.com/forum/showthread.php?t=193623&highlight=adjusting+brush

Up is up and down is down on voltage. G.M.

Moving the 3rd brush down INCREASES the output. Adjust by referencing the ammeter.

Sorry GM but that is not correct. On an early Ford V8 moving the third brush down (clockwise as in engine rotation looking from front of car ) increases the generator amps output. Pushing the third brush upwards or anti clockwise against engine rotation decreases the generator output in amps. Regards, Kevin.
