Power to box, none inside

We bought a 1978 dodge sportsman. We plugged it in but none of the outlets inside have power. Tester shows juice to box but not inside. My husband is in the process of taking down ceiling and has all light fixtures down, is that why there is no power? Or is there some trick we don't know about? Lol.
No manuals.

    The trailers are built to operate from both 120VAC and 12VDC batteries.

    The concept is to use the 120VAC coming from shore power or a connected 120VAC Generator for the high wattage appliances and use the 12VDC for the very basic items such as ceiling lights, detectors, small wattage items, etc...

    When you plug the trailer into 120VAC then the on-board converter gets 120VAC power to keep your battery charged as well as run the 12VDC power distribution panel.

    This is neat electrical block diagram for a typical 30AM Trailer setup...


    Do some reading up on line how the RV TRAILERS are suppose to work before tearing into everything. You will soon as a big mess on hands tearing it all apart...

    Just install a good battery and your ceiling and other lights should work off of the battery.

    Lights are 12V DC
    Outlets are 120VAC

    Check AC circuit breakers.........Main ON and individual CBs ON??

    Does it have a generator?
