So I just broke out my CPS3 yesterday for some 3rd Strike and noticed that my 2p button 4 was stuck pressed. When I unplug the controller (tested multiple good controllers) button 4 comes unpressed, then when I connect it and press the button once it stays stuck.

I'm guessing the resistor pack near the CPS2 kick harness must be responsible, right? It would be RA2 in this picture:

If so, does anyone know a suitable replacement part, or how I can determine the correct values for a replacement using my multimeter?

you need to trace back button 4, the RA might just be there to hold the inputs high and all the signals are controlled by the chips or diodes.

Thanks XX. It actually ended up being a strange problem with my supergun, it works fine in the cab. :-J
