I have internal lights when hooked to a battery, but if I try to use a wall socket POOF!! It either blows the breaker or the source of power's fuse. Any Ideas?? PS: What is the most efficient combination of propane generator/battery power,(opinions of course) I use propane for the frig and have no A/C, I have propane aux heater at the door. The computer and stereo are the only electrical "heavies". Thanks for your opinions in advance.
OK, clarification... Are you talking about plugging your trailer into the ac in your house or are you talking about plugging an appliance into the ac outlets in your trailer?
Sorry I'm not following it - I'm just dense tonite...

Something is throwing the breaker if I try to plug it straight into the house. (If I use a wall socket in the trailer) Something is blowing the fuses out of the vehicle if I try to get my power source from that battery. (as soon as I trip the breaker to "on" in the trailer) Follow me yet??? lol
What's plugged into where when all these breakers are tripping? For instance, are you plugging your trailer's shore line into your house? If so, what trips - a breaker? A fuse? In your house? In the trailer?
Are you plugging a 110V appliance into a trailer convenience outlet? What blows? Is the trailer plugged into shore power when you're using the convenience outlet?
Sorry I'm so dense, but a clearer picture will help to figure out what's going on with your power problems...
If I'm reading this right the 12V is working ( overhead lights work off 12V).
The AC (110) pops the braker when pluged into outside power and you try to plug anything into a wall socket.
I am assuming the braker in the A/S is poping not the outside power source breaker.
I would first verify "nothing" is pluged into any 110 outlet and the Air Conditioner is off. Flip all breakers to to "off" position, plug in the AC outside source of power. Flip the breakers back on one at a time.
What happens will lead to the next step !
Exactly!!! But there are only those 2 breakers back by the toilet?! The A/C? any way to disconnect it? I tried turning it off at the wall, no luck. I have NO idea if it even works to be honest. Where does the power come into the A/C? Maybe I can disconnect it.
Received your PM and replied.
Yes flip one, if trips leave off and flip the other on.
If one stays on leave it on and flip the next one.
The object is to find out which breaker is feeding what.
If one breaker trips and the other is OK plug a lamp into a 110 outlet. This will let you know if the problem is in the ac or wall outlets.
I am assuming at this point you don't know if the polarity light is working.
One other thing. On the breaker with the wall sockets is the plug for the fridg and the univolt. One of these could be poping the breaker and you may have to unplug these one at a time to isolate the problem.
...your trailer breaker pops when you plug into external 110, or after you've plugged into external 110, and then try to plug something into one of the 110 outlets in the trailer? If the latter is true, does it pop when you plug the device into the outlet, or after it's plugged into the outlet, but when you attempt to turn it on?
The breaker pops as soon as it gets external power. Gen., House, whatever. There is nothing plugged into the wall except maybe a draw from the A/C coming from some wall goblin...
Sounds like you've got a short somewhere in the 110V system. I would check that your AC is wired correctly with no chafing of the sheathing, and that the connections between the two are well insulated.
I would also check the connections on your univolt. Early ones were direct wired from 110 into the inverter. Later models simply plugged into an outlet.
I had a similar problem, and it was an exposed wire grounding against the metal case of the univolt. It wasn't immediately apparent.
