So this has more than just me stumped.
Symptom: shooting the right ramp does not advance flop, turn, or river in single ball play (perhaps other times, too?).
Both ramp switches are working properly, and the post will stop the ball at the top, then quickly release it onto the upper playfield without ever advancing the poker hand. Both switches work find during the game, and in Switch Test.
Left ramp works fine. Game recognizes whenever the ball is resting breaking the opto at the top.
Sporadic behavior, but far more common than not. Suggestions appreciated.
