    This photo shows the proper connection of the motor leads as they connect to the board. It is critical that the red positive lead connects to the positive lead on the board. It will be the black prong coming off the board towards the back of the handle. It will also be necessary to bend the two prongs slightly toward the valve body so all will fit when the top half of the handle is replaced. Place the other half of the handle onto the unit and screw the bottom screw and the front screw in place. Once complete, reconnect the battery. Use caution when replacing the battery. Do not touch the contacts backwards. Once installed, close the battery door and screw the door in place.
