    This little rusty electronic device is wired between my battery and my camper. Anyone know what it is and what it's purpose is? See pix.

    It’s like a fuse that will reset. Usually 20 amp. An auto parts store should have it.

    The OP's 2003 Sun Valley is spec'd for a 15 amp circuit breaker.

    Slightly off topic, but shouldn't the two positive posts be connected? Testing myself - not you [:)C]
    Edit: as the others have said, it IS a circuit breaker.

    Those are two 6 volt batteries hooked in series.
