Re: Rubbing/Whining from motor
Did they forget to charge it? A stalled armature(not enough power to move the cat, but the operator keeps their foot in it anyway) will make some serious heat, or low voltage could cause the motor to overheat due to increased amp draw.
Did they pull it back with it in Run mode? In run mode the controller will use regen braking to prevent the cart from rolling away, and will cook the motor.
