Hey everyone,

My Grand Prix started to have this issue intermittently. It will countdown bonus at the end of one player's turn, go through the reset sequences, advance players, but not kick the ball out. then the game thinks the next person drained, it will count down bonus for them, go through the reset sequences, advance players, then kick the ball out. See video below at the 8:20 mark.

thanks in advance for the help!

Thanks. Refresh me how the score motor wheels are numbered? I know some you don’t count. From left to right if I’m facing the backbox and looking down at it, how are they numbered?

Thanks again. Haven’t got to messing with it. Probably get after it Saturday.

Finally think I have this licked. The issue was the switch stack #4 on the score motor. This has 7 switches on it. Three of them I needed to clean really well and gap perfectly to fix the issue. They were:

Top eject
R&L eject
Ball release

So basically if the ball would go into the top saucer or either side saucer, or the outhole, sometimes the ball wouldn’t kick out on the first pass of the score motor. It would take two to three times then it would kick out.

So I cleaned the switches really well and gapped them a few different times and it seems to have fixed it.

Man that was super annoying. I’ll report back if that is not a permanent solution, but for now I’m marking this as resolved. Thanks for all that helped!!

Bringing this back as the issue is still here and I cannot fix it. One last try before I sell the game.

Every time it skips a player, the game counts bonus, moves to next player, barely kicks the ball, scores 1k points validating the playfield, ball falls back into outhole, counts bonus for the player that is now up, then moves onto the next player and kicks the ball out.

The score motor switch stack associated with the saucer kickouts and outhole is adjusted and cleaned ten times over. I’m convinced this is not the issue.

Thanks!

I think the part that needs attention is why is the game scoring 1,000 pts when this issue occurs?

I have gapped all the 1k switches in the game so there is no chance one is too close.
