I am working on a DERR and the ball trough is not being recognized in switch test at all. All switches are good. I checked them all as far as continuity.
In switch test it does not even react to closing any of the trough switches. The game also says "6 balls missing" in normal mode. I see no hacks that make me suspicious ... what gives?
Seems like the entire row of roller micros are not even being seen???
