I'm working on a Genco Step Up.

I had the scoring working, but the steppers wouldn't reset. Now I have the stepper resetting, but I have no scoring (ah, Genco).

Mercifully, I do have a schematic for this one, unlike the other Genco (a Blondie) that took me months to figure out... so I'm working on tracing down the problem.

The schematic for this is quite different than any other I've worked with-- it's an actual physical layout of the wiring of the machine. No wire colors are noted, but it makes tracing shorts pretty easy. There's no key on the schematic, so I'm wondering if I'm correct in my interpretation that the "white" switches are normally open, and the "black" switches are normally closed.

Thoughts?

Thanks gents! The tilt switches actually seem to be where my problem lies, and it's left me scratching my head. I'm going to tinker some more this weekend, and should have something to report.

Correct.

That's exactly what I did! It was only $4 to have large prints made at my local Staples, so I had them make a couple of copies that I've been marking up. It's really a cool way to make a schematic, but I can see how it would be untenable for more complicated machines-- this one is pretty simple, and it's still packed enough that it can be hard to follow an individual line.
