I posted a thread last week looking for help with a button issue I was having. Button 4 on the 2 player side in my cab wasn't working. I traced it all the way to the Jamma harness and it works to that point. The two wires are on the underside of the Jamma harness. "b" = black wire & "Y" = purple with white stripe. I used a multimeter and verified that these wires worked from the control panel past 2 sections of AMP connectors down to the harness.
That leaves me with the knockoff Capcom I/O and it has some wires soldered to what I think is the 4 player connector? I would like to try and fix this without having to by a new I/O. If anyone can take a look at my pics and offer some advice, that would be great. Basically Im pretty sure the wires that are soldered to the 4th connection from the right is what is stopping button 4 on the 2 player side from working.
