Would love some help on this. My game has a jumper from the start button to allow autoplay (previous owner). Any game, I get to the last ball (5) and once drained, the game stays on ball 5. I adjusted the switches on the Game Over relay but it didn't seem to help.

When on the last ball:

If I manually pop the relay, this is what I get:

So first, what does the number 9 in the back glass mean? There are 0-9 on there and I don't get what they have to do with this relay. Second, does this just seem to you guys to be a bad coil? Or should I start somewhere else?

This overlaps a question I posted in the General EM sub-forum. Moderators please feel free to delete that post.

Revisiting this for more help. I have 2 problems that baffle me.

1) 3 Ball game works perfectly fine, but 5 ball game will get to "Last Ball" and never go to game over when the ball is drained.
2) In 5 ball, reset the game, close the trough switch, the ball counter goes to 1 as it should, and Sequence #10 immediately trips. If I try to reset that relay, it buzzes.

And help or direction would be great.

Yep I got a loose one. Gonna pull out the main cabinet board today and do a cleanup and switch check on everything.
