I’m trying to figure out what I’m doing wrong. Have a 1 line, 3 credit, 3 reel Triple Double 3x 2x. Problem began when the 801 door I/O board fried. I replaced it and had to replace the button panel wire harness because it melted in areas. I have now replaced the wire harness twice because of the same issue power to the cash out and bet one credit buttons only. I think the issue is with the door I/O board. I have tried 3 different 801 boards (all from working machines). One has no button lights working one has 2 button lights working. It’s not the bulbs. I am in key chip setup and spin reels doesn’t work. Also swapped around button micro chips, no difference. Both wire harness I tried have no part numbers on them. Is it possible I need to use a 14940201w board instead. I have a similar machine with the board in it. I’m stumped? Please help
