Have a Super mario bros; I'm a rookie, but I feel like this will be an easy fix for you pros. All of a sudden, without me doing anything the lower right flipper just went into the up position- and stayed there. It only does this when a ball is shot out into the shooter lane and then stays up until the ball goes back into the holder with the other balls- basically the entire time a ball is in play. Once the machine is off or there isn't a ball in play it goes back to normal postion- but pressing the button on the side of the cabinet doesn't make it go back up. First thing I checked was the fuse, its good, so I'm stuck. I also checked that the trigger at the button wasn't stuck in the connected postion- but its not. What I did find was that the part of the flipper mechanism that is wrapped in orange paper is really hot when the game is on- I assume from working so hard to keep the flipper up. Also noticed that there is some sort of battery pack with only one of its 2 wires connected to the flipper (not sure if thats significant, just thought i'd mention it incase). So that's where I'm at, any help would be greatly appreciated. thanks everyone.
