Quoted from Chitownpinball:
Im working like mad for the next few weeks, I may have a moment to mess with machines in the future, but nothing planned.
Any one want to throw around the idea that i blew something when i put the cpu rom in the wrong spot? I cant think of any other reason why it would just stop working at that moment.
Did you get this figured out yet? I had a guy come out to look at my raptor pit and it turned out the wire to the coil had come off. Why did I not see this (the most OBVIOUS solution known to man)? Because there was a clear plastic sleeve holding the wire right at the point of connection to the coil, making it look as if the wire was still connected! I pulled the sleeve off and boom, there is the disconnected wire. So frustrating, but glad I got my raptor pit firing again!
Hope this helps.
