I'm troubleshooting a new (to me) Solar City. I got the bonus stepper de-gummed and am now dealing with (what seems to be) a stuck 10 points switch somewhere. The game resets properly (as far as I can tell) but as soon as ball one kicks to the outlane the 10 chime sounds and you can no longer score 10 points anywhere. The 10 points relay is humming and on as well. (It activates properly during score reel reset but then engages and stays on when the game begins).

So... my dilemma... since they're all on the same circuit I can't check with a multimeter (since they all read closed when one is closed). Any tips on finding the offending switch or do I just need to do a really good visual on each one?

Also... it looks like the slingshots and the switches behind the drop targets all should score 10, any others? Everything else on the playfield appears to score more than that.

Thanks!
Steve

Yes, I have the schematic... and yes I believe I have them all accounted for. My issue is that they all *appear* (visually) open and I don't see anything funny with the solder points touching etc. Yet somehow they read closed, and obviously if one is "closed" electrically they all read closed at their individual locations so I'm not sure how to figure out which one is the culprit!

Got it! Thanks, all. It was an oddly bent leaf partway down on one of the switches behind the uppermost drop target bank.
