Gottlieb Royal Flush (Gottlieb, 1976) Help!!

[Bobsterx]

Game starts properly pressing only one player. The game plays player one fine, then skips second player to third player. fourth player plays fine. Should be playing only one player but but plays 1,3 and 4. Where should I start.
Thank You

there is a wheel usually bakalite with contacts on the bottom of the cabinet when you turn the machine on it goes around and resets the scores take apiece of light grade sandpaper and clean those contacts on the wheel. my old 77 bronco did the same thing it cleaned that problem right up. hope this works for you.

I always used an emery booard of nail file for contacts. Easier to use and fit in tight places.
