The PM guy said the reason for no high speed was that I have the incorrect batteries and using the incorrect charger.
I have a 12v charger. There are 4ea 6v batteries both pairs are wired in series to make 2 12v circuits that run parallel. The only time 24v is reached is supposed to be when the high speed switch is activated and a contactor connects the two 12v circuits in series and applies 24v to the drive motor.
