What do these schematic symbols mean?

    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?

    I agree with your interpretation.

    I assume you are seeing this in the actual switch configurations.

    The defining evidence is which way the switch is moved when the coil is actuated.

    I also agree with your interpretation. You should be able to verify it by looking at the tilt switches. Are they presently open or closed?

    The one to the far left of the one you marked "NO", appears to be a "make/break" switch.

    Marking up a photocopy with a bunch of colored pencils or markers would make this schematic easier to use in the future.

    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.

    This is for Williams but looks to hold true for your Genco schematics too.
