Time Soldiers player 1 controller

[Romulet]

Hello everyone, I'm new to the site. I have posted in the monitor section and now I'm posting in this section. I have bought myself a time soldier arcade cabinet in really good shape. The problem I have is the player 1 controller. When I play player 1 the character turns left 1 notch and stays there, I can't turn him around or anything but the joystick works I can move the guy but I can't turn him 360 degrees. I took player 2 and hooked it up to player 1 side and it does the same thing. I hooked up player 1 to the player 2 side and it works. It spins around and walks around so I know it's not the joystick.  This has worked over the person house that I bought it and since I driven  it back 70 miles it doesn't work now. I have narrowed it down to a black box from the player 1 joystick and it is going to the JAMMA board. I think that is my problem. Maybe a loose wire or something. Does anyone have that part or should I just re solder the JAMMA board connector?

Thank you for your time.
