Probably not your breaker box but the converter charger. Time to update. Try "bestconverter.com" for a replacement

In that vintage of RV the odds are you have one of the old Magnetek 6300 boxes (or similar) that combines 120vac and 12vdc components in one package. Stuff gets old and insulation breaks down, and the 12v converter/charger portion of that box is antique technology. A replacement would be a GOOD THING. If its the 6300, you can buy an upgrade to the 7300 technology, which is substantially better and an easy replacement. With a bit more effort and wiring skill, you can tie in a PD9200 converter/charger and leave the old 120v section (it is probably fine). See bestconverter.com for replacement choices and info.

Does your breaker box also contain 12 volt fuses or breakers? IF so then the converter is most likely mounted behind the thing (part of the same assembly)

Since converters are notrorious for not knowing the lyrics they tend to "Humm" and the only tune they know is "Johnny one note" and that note is either 60 or 120 hz.

Ok, so the last paragraph is a joke. It is also true.

Any chance you can put up a picture of the suspect components?
that would make it easier to figure out.

This forum has a really good iphone/android app that makes it very easy to post pictures.

Wiring diagrams are VIN specific in many cases.. And in many cases may have changed since date of manufacturer if any electrical work has been done on the RV.

Recommendation.. Plug a light into each and every outlet, Turn on TV's radio etc.

Now one at a time.. Turn off a breaker (Other than main) and note what does not work (Air conditioners on FAN mode) .. Use a Brother P-Touch (or equivalent) to make a label and label it.. Now move to the next breaker, and so on.
