Hi Dan, I almost got it all today. I cleaned all the contacts on the Player Unit in the head, and then it went through a complete Start cycle. The game plays as it should ...EXCEPT ... when it lights up 2X bonus, it actually pays out 4X bonus. .... I guess the 4X contacts are 'closed' ?? when they should be 'open'.?? ...but where would this be??? I'll keep looking. ...also had to give the 0-9 unit a revive. I also noticed that the 'First Ball' relay would be on until 'Game Over'. Do you know if that's normal? Thanks for getting back.
