When connecting an AX550HESE for a unidirectional application, I understand that the power source goes to one side of the motor and the green #8 wires go to the other side. My question is do the red wires have to be connected to anything or is all of the control handled by the black and green wires?
Red, black and green wires need to be connected. White are left floating.
Red -> battery +
Black -> battery - and one side of motor.
Green -> other side of motor.
If motor does not rotate in the desired direction, then reverse wires to the motor or connect white and leave green floating.
