Quoted from TheMaze:*sigh* I hate people.
First I found the 6VAC (pin 1 and 9) for the coin door light seem to be hacked to the same light terminal. Disconnected one side of that - no change. My best guess is someone tried to wire the coin door lights in series for +12V bulbs, but shorted it together.
That didn't fix it, so I did a bit more digging and realized what happened. Someone had hooked the wires on both coin slots to the wrong side (NC side). Moved them to the NO side and the tournament switch works as expected.
I just had the SAME issue SAME game. Pulled the coin door connector and it came up in Tournament Mode. Swapped the pins on the coil slot switches and boom. You saved me a ton of time. I was starting to pull my hair out here going WTF??? Already knew all switches were good so I was like "this makes no sense" My coin doow was not hacked at all. Just someone swapped the leads on the coin slot switches. Nice catch man...and TY!
