I am trying to get an old arcade game powered up using a standard atx power supply spliced into a proprietarily wired 214 pin molex. I have attached the pin-out schematic of the board side of the proprietary harness. I have also attached a verbal description of said pinout. The atx power supply was known good before I cut. With pins 1 and 13 jumped the supply powers on. Pin 15 and 14 test fine but 20-22 test of OF. The way I have it wired now is one 5 volt lead per pin but does this schematic suggest that my problem is that I should only be attaching one 5 volt lead in to all three.?
