Just got a Williams Grand Prix and have already worked out a lot of issues.
But still have a few problems
1. The left player bonus count down stepper unit is sitting between the two contacts instead of being in the center. (Photo Below). Is there an easy way to move the round wheel of contacts that 1/8 of an inch to get it back on center of the tabs. We tried loosening the big nut in the center but could not budge the orientation of the contacts.
2. The center 5000 point saucer at the top of the playfield always scores 5500 points. Both the 1000 chime and the 100 chime coils pulse 5 times together when the ball goes in the saucer. Very strange because no other 1000 point score will cause this. Just the saucer.
3. The game just started always being a 4 player game all the time. It will always, even on a single player game progress to player 2, 3, and 4 and then just get stuck on player 4 forever. The only way to get it back to player 1 is to credit up a new game.
Any ideas welcome with these 3 problems.
