That’s the replay stepper unit or counter. Should step down when credit button is pressed (new game started) or step up when replay is awarded (at set high score). If it’s always going up at a score of 100,000, then the replay score must be set at that value. If you’re consistently getting scores of that, you’re either very good or there’s something wrong with the scoring. Does it go down when you press the credit button to start a new game?

This isn’t right. It sounds like a spring issue and looking at your picture of the replay unit, one of the springs looks stretched a bit. Replacing this spring might solve this problem. Sometimes good hardware stores have springs in stock, although you’ll need to be lucky to get exactly the right size. If they don’t have the exact same size, get one with the same tension (you should be able to find one with similar gauge and diameter) and then cut it to length (of the unstretched spring) and bend the cut end so that it can be attached to the unit.

You can check to see if this spring is the problem by watching this unit as a new game is started. If it were me, i’d simulate the effect of a stronger spring (with a strong rubber band or by connecting the current spring at one of the spots where it’s stretched out or by putting pressure on the moving part of the unit) before running out for a replacement.

Otherwise it sounds like replays are awarded at 100,000. Are you scoring above this often? I’m impressed if so as it only occasionally happened when I played this machine.

Mopar is correct that it isn’t the spring. The step up coil firing is the problem (the second coil that fires in your video) and so you’ll need to trace what is causing it to fire. Below is the part of the schematics that has the coil in question in it. There presumably is a switch making contact where it shouldn’t that is causing that coil to fire (e.g., second coin chute relay switch).

Mopar or HowardR likely has much more experience than I do and may be better at walking you through the schematics and indicate possible switches to check if you want to attempt to get this to work as it should. Good luck!

And your video reminded me how wonderful the spinner chime of Aladdin’s Castle is! Enjoy!
