Hey folks, I recently bought a pop up trailer and am opening it up to go through. I tried to plug in the electrical line to my garage to use the lights, fans etc while at the house. After plugging in, it isn't turning on the trailer fans, lights etc????? Is there a switch that I need to know about for using a land line? I hooked up the battery cables on the front of the trailer to a battery thinking I needed that hooked up to complete the system (battery is dead), but the electrical still isn't working. What am I doing wrong????? Would the trailer battery have to charge some before the system works (plugged into the 110)? Thoughts

We have a Starcraft pup and our safety switch is on the dinette under a flip up seat back.

Do you have a flip over, or fold over galley? And do you have it set in place? Pups have a safety switch that is pushed down by the galley. It is to prevent the lights from being left on while the pup is down, and burning a hole in the canvas. The lights will not work with the galley in the travel position.
Other than that, Check your fuses, and breakers

BTW Galley = stove, and sink. Look for a push button under it.
