I am trouble shooting my NASCAR yet. I am dealing with two opto boards (1 and 2) needed to run 3 switches (37, 35, 34). No matter what I swap, J1 and J2 do NOT work on both boards. I have swapped the boards. On board 2 (only one channel needed) that is supposed to be in J1 and J2, the switch registers closed at all times. When I switch it to J3 and J4 it works. I have checked wire continuity to the I/O board and switch column and row. I can NEVER get one of the switches (37) to register in switch test or game play. The switch 37 receiver and transmitter work for that switch because when I switched 35 into those two receiver-transmitters, it registered correctly as switch 35. I can NEVER get switch 37 to work! Any suggestions?
