Radio Issue

[RetiredVOMA]

2009 Fleetwood Bounder 35H (2008 Chassis). I am replacing a radio and have run into, likely a self induced, problem. I was testing the radio prior to actually seating it in the RV. I believe I shorted it out while moving it around. The radio was functioning just fine until it didn't. I have two connectors from the RV harness. In the photo you can see a large one and a small one. The issue is that the red wire in the small (2 wire) connector has lost power. This is the power that retains the radio memory. There is no power at the red wire and now the radio does not work at all. I contacted REV and they gave me some info on fuses in the BCC but they also stated that my bus is pre bankruptcy and after the reorganization a lot of info was never transferred over to them. I have checked all the fuses that I can find. There are the ones under the cover on the dash itself, the ones in the BCC and the ones in the engine compartment. Logically I would say that there is an inline fuse somewhere but 6 inches after the connector the wiring goes into a bundle and then that joins a larger bundle. Feeling and looking for a fuse has led nowhere. The writing on the red wire says AUX PWR. Does anyone have any known correct information where the AUX PWR begins or a diagram of the actual wiring. REV tried but they just do not have it so I'm hoping that someone in cyberspace has the answer.

Thanks in advance for anything you can offer.

EDIT .... Sorry, apparently I am unable to post a picture of the connectors.

All of my diagrams are for a diesel chassis. The BCC is usually where radio power comes from. I show it as a 10A fuse labeled F16. Good luck.
Edit to add: I will note that my radio died once...and it was the fuse in the harness of the radio itself. It was a glass cartridge fuse that was difficult to obtain.

Adding this document. There is a fuse panel in my MBR that has these fuses. Maybe helpful. Circuit #650 may be of interest.

I am a gasser and your suggestion is a good one .... but not the correct one. There are a couple possibilities in the BCC and at least one in the inside fuse buss but I have ohmed out every fuse and have searched for power at the fuses. Anything remotely connected to the radio checks out good. I'm desperately seeking where the red AUX PWR wire begins. No power at the end of the connector. I have tried to see if there is an inline fuse but the cables are all bundled under the dash and then they go into a larger bundle. Lost, lost, lost !!!


EDIT ... radio fuse is fine

650 does mention DVD which seems to be close but these busses are different from mine. My best hope at this point is to find where the AUX PWR wire begins and so far no one has that answer.
