    Hi! My first post, so I apologize if I'm asking something that may have been asked elsewhere. I couldn't find anything by searching for the model. A friend gave me a dead Bose AWR1-1W to look at. I gather there are several versions of these clock radios around; this is the one with 3 AA batteries for backup and an F-connector for an external FM antenna.

    Anyway, in removing the cover I broke the connections from the internal ferrite bar antenna to the PCB. The rod was stuck to the top cover. I can guesstimate which lead went to which terminal from the length, but I'd rather know for certain. I found a schematic at but it's not helpful. Anybody have one of these who can help?

    Sorry for not posting a picture of the antenna or board, but all my attempts so far haven't been clear enough. I'll add pix if I can get some.

    Even with a schematic you'll need to guess at what winding is what, However, you will be able to confirm continuity exists where it should.

    Figure out what your best guess is, then trace the connections on the PCB to determine which each matches in the schematic.

    Finally determine if there is continuity between the wires that you expect.

    Now you will have one potentially correct combination of wires. Go ahead and solder them in (watch out for wire that is very hard to solder) and see if the radio works. If it does, great. If not perhaps one of the windings is backward (swap the wires) or perhaps you need to swap windings from one place to another.

    Thanks! I used to be a professional service tech (TV/other electronics, computers, appliances, etc.) but I'm not in that biz any more. The soldering doesn't worry me (solderable insulation on the leads). There are only 4 wires from the rod antenna. I just was hoping someone could tell me which wire went where so I wouldn't need to do it more than once. I've just tacked them back on based on the length. Worst that can happen is the reception will be lousy and I'll switch them around. But as this poor critter is dead I still have more to worry about. SMD parts are trouble for me with crummy eyes, and I see a bunch of that stuff here. So far all I know is that the fuse is good and there's nothing obviously bad (swollen caps, smoked parts, bad solder connections, etc.). It was a "dead after a storm" failure, and those were always my nemesis.

    As Steve said .. even a schematic isn't likely to tell you which goes where

    The only real way would be to have another unit to compare it with
