Picked up a Mars Trek a few months ago, and finally have space to set it up. First issue is that anything worth 1,000 points will not score, no chime, no score advance. When I manually activate the 1,000 point relay in the back box, the reel will advance, chime will sound. Also when the 100 point reel rolls over from 9 to 0 it will activate the 1,000 point relay as intended. Top hole (worth 5,000 points) will activate score motor and kick out the ball, but no scoring. Nothing on the playfield worth 1,000 scores.
Second issue is that the ball count unit doesn't always advance. Pretty sure I just need to clean and rebuild that stepper unit. Other issue that I believe is related is that I set it to 3 Ball play, but it always plays a 5 ball game. The ball count unit disc seems to have a lot of some type of lube on it, and the traces seem pretty worn from the wipers, is it salvageable? Picture attached. Thanks for any help!
