Hi All, Im a new owner of a WW. Looking at a test report it says ball trough #5 and #4 are stuck open. Game seems to play fine until a ball is physically locked: when I put a ball in the elevator. When I do this, 2 balls are released into the plunger lane. Any idea how to fix this? I have re-seated the wires to the optical board of the ball trough, but that didnt do it. Thanks! PS, first JJP too, so feeling like a newbie...
