I've been working through the various issues of machine over the last week and it has come down to these last 2 issues(so I hope.) The 3 "SPIN" saucers when activated will spin bonus wheel and eject the ball only if one of the advance bonus switches(standup or rollover) have been hit. If the ball ends up in the saucer(s) before hitting one of the Adv Bonus switches it will spin wheel and never eject the ball. Lastly, the center bonus wheel doesn't hit the initial rpm to free the lil bonus ball for a new random award on the wheel. Point to note: This bonus wheel and motor came off an ugly working PF that spun it just fine, in fact lower control board is the same being used for this PF swap. Also a full 27+vac does power motor which is the motors rated voltage.
