I'm in the process of restoring a Gottlieb Amazing Spider-man machine (my first) and after swapping out the evil orange capacitor and installing all new boards, I'm having the same issues as day one. The machine will turn on and light up, that's it. No sound, no attract feature, no digits on the displays, nothing. Prior to installing the new boards, I tested all fuses and bridge rectifiers which all tested & read correctly. The new boards (Flippp) have LED's that are supposed to light up to diagnose any problems but even those do not light up. With that said, I believe the boards aren't getting sufficient power to properly start a game. Could it be something else in the power supply in the cabinet or maybe the wire harness itself?

Any help would be greatly appreciated!
