I'm working on a pat hand and have two problems I can't figure out. The first is with the bonus unit, it was jammed up and giving to many points because it would not step down right. I fixed that and got it work smoothly in both directions but now it won't score any points. The second problem is the special relay will not trip when it is supposed to. After completing the ace, king, queen, jack, 10 the first time it lights the top rollovers. the second time the double bonus but the third time it won't trip the special relay. Any help anyone. Thanks Bill
