hey thankyou!
it was clunking in both fwd and rev directions...
its no longer the case...
ive messed with the potentiometer again and contactors again also...
after cleaning and degreasing the microswitches for the fore/aft joystick horizontal movement. after the dirt removed, one swith is not activating...that will need adjusting...
the motor brake switch and both platform switches are good.
battery voltage is ordinary...24.7
drops really low quick, like to 16...
