    I want to fabricate an electrical drive for the leadscrew on my metal lathe. I purchased an automobile sunroof drive motor from the surplus section at Princess Auto. I purchased a 14.4v/4 amp wall-wart from the local goodwill store. I also purchased a motor control assembly from www.ElectronicKits.com. The mechanical portion of the fabrication is complete and I am in the process of completing the electrical portion and have a hookup question. I want to put a DPDT switch in the circuit to control the motor rotation direction. Should I put the switch between the wall-wart and the motor controller, or between the motor controller and the motor?? Heres the URL for the Motor controller, which shows the schematic: http://electronickits.com/kit/complete/motor/CKMX033DATA.pdf

    I'm not electrically illiterate, just severely challenged.

    You must have the correct polarity from the 14.4V wall supply to the speed controller for it to work.

    Put the reversing switch between the controller and the motor, that should work fine.

    Voltage Reversings are done for the motor, not for its controller. So 2nd option.
