Hi all, I'm new to the Unisystem as of today, so I'm climbing the learning curve. The cabinet I acquired (Super Mario Bros in a dk cab) will coin up via the service switch, but neither player one or two start will start the game.
I checked the grounds. All of the grounds on the player one side, along with the p1 and p2 start have continuity. Here is where I made an interesting discovery..there is a secondary harness for the player 2 side and it is connected to the other side of the pcb board.
The grounds on p2 did not have continuity. It seemed some of the cherry switches (maybe) were connected backwards, so I was able to change a few of them and get continuity on that side/harness, which then broke continuity back on harness one….i changed it back to the way it was .
I'm thoroughly confused. Research seems to indicate this harness was probably originally intended for a dual monitor cab, but can work on a uni cab if wired correctly, but based on the above, I'm pretty confused what that should look like. I can't seem to find the pinouts for the harnesses either. Any assistance would be appreciated.
