I'm new to this site so please give me a chance if I'm in the wrong area, Hi everybody I got a GNR pin on the weekend I have waited since I was a kid to get one and am wrapped to own one now, it ran for about 10min and then started not letting you fire the ball instead it just keeps going through the "pick your feature" and the gun sound going off it has no flipper power or plunger any ideas. the guy that I bought it off said he took out the battery back up so the batteries don't leak I don't know what that means if that should not be done please any help.
