Quoted from wdennie:Not crazy, if the balls do not get loaded in the correct order, the machine will continue to try and stage 3 balls.
With a diverter not working, it can't position the balls correctly.
To verify, you don't have a optic problem take all balls out of the game, drop a ball down each (3) kickouts.
put the last 3 back in the trough.
Turn on game, It should be set and not cycle.
Correct, this is not crazy and will absolutely happen if your diverter isn't working. Fix the root cause of that and you'll almost certainly fix your staging / ball cycling problem. Personally I'd start with the simple stuff and make sure it's not just a broken wire at the diverter coil
