I took a coindoor off of an old cabinet to use with my mame machine, but I'm having trouble wiring it. It has a counter on it too, which makes it a little more complicated. Theres 4 wires: white, brown, red, and black. So far, I've connected red and black to +5 volts and ground respectively, and I wired brown to "5" on the keyboard encoder (I didn't connect white to anything, and it didn't seem to make a difference). Well, it worked for a while, counter and everything, so I turned off the machine and then back on and now nothing is working, and I think I blew a pin on my encoder because "5" will no longer register at all (all other buttons still work), regardless of what is hooked up to it. I obiviously wired something incorrectly, so if anyone knows how to wire these properly or has any suggestions, please help me out. Thanks
