Title: Control Panel help.
Post by: Oni2382 on October 19, 2009, 01:42:49 pm

I have a Tekken 4 machine in a Blue capcom Dynamo cab with the following issue. When ever I push up on the joystick, whether it's the 1p or 2p side BOTH characters move up. This issue only happens when pressing up, all other functions work properly. I swapped out PCBs and its the same issue. I inspected both micro switches and they are NOT connected to each other in any way. The edge connector for the Jamma harness looks fine as well....Any ideas?

Occam's Razor - there's got to be a bridge somewhere.  Double check the wiring again.

OK I will double check....Could there be a possible bridge in the ground wires??

That would be fine. Grounds are all connected anyway.  No, it's got to be something else.

Check your harness carefully.
