Had an issue with the machine auto launching balls at the beginning of every game, every new ball, etc, before I could select a mode. Narrowed it down to the left ramp entrance opto being loose and switching everytime the trough upkick cycled. Problem diagnosed, now just have to figure out how to fix it. Problem is that in raising and lowering the playfield I screwed something up and none of the coils in the machine work other than the one that shakes the Vengeance.
This is when playing a game, no ball kicked into the shooter lane, no flippers, etc. Same in coil diag, only the Vengeance works. Switch diag looks ok. Trough diag is no go as well, totally dead. No technician alerts. Fuses are fine. I plan to call Stern tomorrow, but anyone want to help a rookie out?
