    So I went to play my Ultra II through the nanomag and got no signal.
    I opened it up and this wire was free. I can't find any broken solder points so I need help finding where it goes. Can anyone help me out? Thanks!

    Do those guitars have two input jacks?

    When I look at a wiring diagrams it does seems to be a ground.
    And yes it has two output jacks.

    Actually I checked that already. It was my first guess but the nanomag jack has all the proper connections, as far as I can tell from the circuit diagrams anyway, and there's no broken solder points.

    It may be a ground to another pot.

    I'll give it a try. Sadly the wire reaches just about everywhere.

    Nothing but a few nasty crackles, unfortunately, even when I try hooking the wire to the ground on the second jack.

    NO,

    they're 'output' jacks :D

    one for the humbuckers or both pup-systems
    one for the NanoMag

    Maybe this thread at the corporate forum can help...

    and a link to a wiring diagram, too

    Well I guess that ground wire didn't need to be connected, as far as I can tell from the picture anyway, perhaps I just screwed up some of the electronics at some point then. I'll contact epiphone tomorrow to see what they think. But for now, thank you.

    And at least the other two pickups still work.
