I sometimes lose power in my 1999 Eagle Pop-up.
Turns out there is a small fuse inside the power convertor that blows ranndomly. what could be the suspect there.
some times it is fine, others it is not......a real pain to change too.
It would be my guess that one of the internal components is failing such as a diode or capacitor. Sometimes when they fail it allows too much current to flow, thus it blows the fuse. More than likely I think you are looking at doing a replacement soon.
