Welcome to the Forum -
Sounds as if you have multiple electrical issues.
First off, I would find out what is causing the main circuit breaker to open ("click and the power goes away") - the circuit breaker is just like one in your house - it takes the place of a fuse, except it sets itself to "on" again after it sufficiently cools. Sounds as if the circuit is overloaded. The overload may will be part of the compressor problem, possibly even the compressor itself.
You may want to start disconnecting circuits one by one (compressor, fridge, charging (both house and chassis batteries)) to determine which circuit is causing the overload. The batteries themselves may be at fault - if they are older you may want to have a shop load test them - anything over two or three years of age plan on replacing - especially if they have been fully discharged once or twice.
Do not check the compressor by simply connecting to a battery. Although the compressor will "run" if connected in this way, there are other circuits (at least on mine) controlling the "on" relay and the "preload dump" valve. Do a search on specific words - especially on the compressor problem. Air bag compressors have been much discussed in the past.
We would all appreciate some pics of your MoHo. Do you have any idea of it's history?
