Jamma wiring issue. Start button for players 1 & 2 don't work
So I was redoing some wiring in my Wrestlefest Jamma cab (converted to Sunset Riders), specifically relocating the start buttons underneath the control panel so I wouldn't have to ruin the CPO. Apparently, I got some wires mixed up as players 3 and 4 start buttons work fine. However, both Players 1 & 2 do not. I traced the wires from the Jamma connector and they are connected correctly.
Solder side 17> Start switch 1 (see start1.jpg)
Solder side U > Start Switch 2 (see start2.jpg)
There is no direct wiring between player 1 & player 2 which is what I suspect is the issue.
I'm going nuts here, but I traced what I could and cannot come to a reasonable conclusion on what I'm missing. I'm a newbie when it comes to wiring, so forgive me for any common sense things I may be missing.
Any thoughts are greatly appreciated.
Thank you.
