No DC Power! Please help!

We have a 1999 prowler travel trailer. When we walked across the floor the lights started flickering and then everything that runs off dc power quit. We have changed the convertor but that has not helped! We tried replacing the breaker. The one that my husband got was too big, even though the lights came on but the ac did not, so he replaced it with the correct size and now there is still no dc power.any help will be greatly appreciated as it is over 100 degrees in Tx right now and we live in our travel trailer. Thank you.

    Make sure the basics are working before you start to diagnosis the problem.


    I would add to check your terminals in your breaker panel as well make sure their all tight and check your fuses and turn on and off each breaker switch.

    AC = Air conditioning
    or
    AC = alternating current?
    Are you plugged into power or running off battery?

    To start with the obvious, have you checked fuses? (The "breaker" is in the 120v AC circuit.) I can't say where to look, but the 12v line out of your converter is one place to look for a fuse.
