I believe I have a bad PCI card. My dart wasn't reading anything coming from the top of the dart board(LED & dart matrix). But while I was reseating the PCI card I also created a new problem. I knocked a plug out. This plug goes to the reset switch on the back of the machine. These machines don't like to come up if this plug is in the wrong place. There is a ten header pins with one cut off on the left side towards the back of the machine. The plug itself has a red and white wire. Anyone know where this goes?
