Hi,

My machine was working great up until the other day when I turned it on and the score motor just kept spinning. I noticed that the S relay continually clicks as well. I am hoping that it is a simple adjustment as my daughter is having friends over today and I wanted to have the old gal up and running. Any advice would be appreciated.

Thanks,
Patrick

Is everything resetting?

Yes

Are the S relay contacts clean and gapped correctly? Check the AX as well.

I am not sure on the gapping question. I do not have a well enough understanding of relay sand contacts to check

The score motor typically continues to spin because one of the switch contacts that feeds it power is remaining closed when it should have opened. Your game's schematic will show all of the circuits (and switches) that feed power to it. This very often occurs with a score reel contact that should be open after the reset is complete, but doesn't due to misadjustment. I'd suggest checking these first.

You can place a piece of paper in the switch to block the contact. Keep moving the paper from switch to switch until you block the contact that was keeping the motor running. Then you know which one needs attention

Will work on tonight. Thanks for all the advice.
