Hey all — I'm having an issue with my Monaco (Segasa, but apparently similar to a Williams Space Mission) that I'm having a bit of trouble diagnosing.

Long story short, after starting up a game it appears that things work as expected until the ball drains and the outhole switch is triggered. At that point, the score reels will run for a while and the bonus relay will activate repeatedly, but the ball never kicks to the shooter lane or advances to ball 2.

At this point, If I turn the game off and on again the start button won't trigger the reset sequence, but manually hitting the reset or coin relays will reset the game. I can also manually advance and reset all the steppers smoothly, so I think the problem isn't originating there.

Any of this sound familiar to anyone?

I've got a short (~3 min) video that demonstrates the issue here: https://streamable.com/s2c2v

Cheers!

Hey all — the mystery is solved! The startup woes were fixed with a switch adjustment on the score motor, and fredsmythson and bflagg were on the money with the outhole kicker issue originating with the bonus unit.

The bonus unit was stepping up and down nicely, but the little arm that closes the switch was juuuuust loose and wobbly enough that it wasn't causing a reliable contact.

Some quick switch tweaks and we're back in business!

Thanks all!
