Game Plan Solenoid Control Board SDU-1 Circuit Boards This new one is muchAs far as I can tell in researching, the SDU 1 board was used in every single one of Game Plan's games.. this one board will replace an original SDU 1 in them all. There is a TVS diode on the board to protect against a bad diode on a coil.. if you do not have a diode or it became defective, the board will soldier on as if nothing happened. Quick drop in replacement, no instructions needed on this one.
