I have searched the forum over and couldn't find anything about this issue. I picked this game up with some minor issues (needed a flipper coil, trough switches, completely cleaned and everything needed adjusted) and am just about to have it completed but I am struggling with the following issues and was hoping one of you could let me in on what's wrong.
When the ball is fired from the shooter coil into the playfield it automatically triggers the tunnel switch (that would give awards bonus or start the video mode). The switch for the tunnel is new but it also did it with the old one. What in the world would cause that?
