At the moment, EVERYTHING is dead, and I have the house batteries disconnected and on a charger trying to get them back. It really seems like my power converter/charger is not working at all, but I can't find the darn thing. I THINK that it is located under the bed, WAAAY behind the power panel, but I can't get to the area because the bedroom slide is in, and, well, there is no power to move it.

Does anyone know for positive that the thing is located back there, or am I missing something?

There are LOTS of little things that I am still in the process of working through on this coach, but this is a biggie for me. It is also especially frustrating, because it is an electrical issue, and I have been an electrician for almost 50 years. My neighbors are really starting to look at me funny.

Does anyone have any ideas for me? There are no electrical drawings that I can find to help me troubleshoot, and no real information in the Owners Manual about the manufacturer, model number, rating, or even WHERE the power supply/charger was installed in the coach.


Sooo.... I finally got the batteries charged enough to extend the slide and dismantle the ridiculously inane cover over the area under the bed, and whadayaknow(?); I found the converter/charger. As expected, it was still virtually inaccessible without removing its mounting screws. Has two 35 Amp fuses on its D.C. Power side, but they were not blown. Also, the unit wasn't running when it ought to have been (all sources of battery charging disconnected, and coach connected to shore power). It simply does nothing but mock me for my efforts at finding it. It certainly doesn't look sufficient for the task at hand, although it's label claims to produce 55 Amps.

Needless to say, Mr. RV Dealership and I have a meeting scheduled for Monday morning.

While I'm on the subject of things hidden which should be accessible, have you ever heard the warnings about asking what's in the sausage you're eating? Well let me tell you, that after seeing all of the wiring and hoses and ducts stuffed under that bed, and about 10lbs of superfluous construction detritus left by the fine folks at Thor, I'm a little afraid to sleep in that bed! Never in 45 years of electrical construction have I seen such shoddy wiring craftsmanship, or generally inferior structural workmanship! Don't those people have any QA/QC? For the price I paid to own this thing, I thought it would have been made with a tad more pride.

Anyway, thanks to all of you who offered me your insights and suggestions. The RV might suck just a little, but the folks on this forum are Top Shelf! You have made this task more of a quest or adventure than merely a sweat-soaked frustration.
