1999 towlite hilo, 24' 30 amp
 

Is there a circuit breaker in side? I can not find one and the ac and water pump does not work. I turned the ac on and it ran about 5 min. and stopped.

There is usually a fuse panel located either behind a cushion located by the couch or underneath the sink area inside a cabinet are the two most common areas.

For running the AC though you need to make sure you have a dedicated 30 amp circuit if you are plugging into your house. If you are using less than that it will trip the breaker on your house circuit panel. That is what it sounds like happened in your instance, if you ran the AC 5 mins and now its not working. So check your panel that is providing power to the trailer.

Also, check the outlet where the AC is plugged in. In later Hi-Lo trailers this outlet is a Ground Fault Interrupter (GFI). If it tripped, you need to reset it. If that's the issue and it trips again you may have a bad GFI outlet, or a current leak in the AC, in other outlets wired to the GFI outlet, or in something else plugged to the GFI outlet or downstream outlets.

The GFI outlet used is a standard household unit available at any hardware store.

If it is the GFI outlet, the a/c GFI is a 20 amp outlet, not a 15 amp outlet. The prong holes are different in the two outlets. The a/c cord will not plug into a 15 amp GFI outlet.
