Help please, I have 5 or 6 system 3's in my collection. Just added SF2 this week , here is the odd thing. Left flipper works fine in game play, but it will not work in modes where you select something, like multiball or 10 million, right flipper works fine. I cant get in to check the switch matrix or testing because I cant use the left flipper to select test set ups?? Anyone had this happen or have any idea.. thanks-
