I checked the wiring one every set up I tested it on and the B button just doesnt want to register. It did work but I want to say I plugged the JAMMA harness in backwards and a chip near the JAMMA connector started releasing smoke after about a couple seconds of powering it on. I expect that chip need replacing and that chip gets extremely hot when powered on with the JAMMA harness plugged in correctly. I appreciate any help and I put an arrow pointeding to the Goldstar chip that smoked and heats up in the PCB picture that I included.
