    I'm trying to figure out what this component is. It has this label:

    CD
    A10CA

    The "CD" part must be the logo of some company, see the attached drawing please.

    The part is shaped like a through-hole diode (black, cylindrical, leads coming from either end), except that it doesn't have the line to indicate the "negative" side of a diode.

    If someone can find this part, I'll paypal you a couple bucks. :)

    Can you post a photo of it?

    Is it a fuse?

    I don't have a digital camera handy, but it looks like this:

    ...EXCEPT there's no white ring around the left end as a diode would have. It's about the same size as a 1n4001 diode though.

    I measured the resistance across it's terminals in both directions; both times my DMM reads about 1 ohm. It could be some kind of sense resistor.

    If it were a resistor the markings would be much simpler and the casing wouldn't be black and shaped like a diode.

    A real picture of the actual device would provide tons of information.

    Take an inductance meter and see if it has any to speak of, at 1 ohm DCR it probably will.
