Please help with electrical problem

dont forget not to use tap water - it has to be distilled water also

We were taught to make sure the liquid in the cells cover the plates - charge - then top off fluids.

Rick,
That is what I meant by "top off": bring the electrolyte level up to cover the plates, which is what the US Navy calls "topping off" (or used to anyhow); it means to bring the level up to the top of the plates (not the top of the battery itself).

The original poster's battery may have gone totally dry in storage and that is why it is not recharging; just one possibility out of many of course...

with the power cord disconnected, check the monitor and see the condition of ur battery.
when u shut off the main breaker, u are checking to see if the fault exist between what u are plugging into and the trailer. all a/c circuits, including the converter, are disconnected from the a/c when the main breaker (in the trailer breaker box) is off.
if u don't throw the ground fault at that point, then u can turn all the other breakers off, restore the main, then start turning them one one at a time. the battery isn't going to play a part until u throw the breaker with the converter on it. that is also when all the dc in the trailer comes into play. if that happens, i would suspect battery or converter but not the other dc circuits. wouldn't rule them out but would check after bat and converter.
this should make it a little easier to isolate.
it just doesn't sound right that the converter would be trying to push over 100 amps into the battery without a fuse on the converter blowing.

batteries can do some strange things. ur bat monitor should be able to tell the condition on ur battery. good starting point before proceeding.
it depends on what is taking u breaker out: ground fault or breaker. they function differently. ground fault senses an imbalance between the hot and neutral...an extremely small imbalance. it assumes another path (short) if that imbalance exist and trips. the other part of the breaker senses high amps. u can try plugging into a non ground fault and see what happens. if it doesn't throw, u either have a bad ground fault breaker or u have a fault somewhere. when u plug in at a campground, u are not on a ground fault.

Thats good, I just wanted to clarify that if he had filled them right up to the top discharged it would overflow when charging (which is how I should have worded it in the first place) Hope I didn't offend

While I also agree that a low battery could make the required current supply increase when plugged in after a camping trip, it shouldn't increase that much, and besides, as stated, even with all of the camper's breakers off, it still trips the GFI. I've seen a few other posts on here over the years with the same or similar issue, resulting in the GFI tripping off. I am under the gut feeling, and mind you I'm NOT an electrician, that the GFI, as named IS a Ground Fault Interruptor. Therefore, it occurs to me (my opinion), that the camper sitting on RUBBER wheels is not EARTH grounded, as I do believe is what a GFI needs to properly complete it's circuit. I also have noted that others have had to change the source of their AC power to a non-GFI house plug, or their own dedicated power box to solve the problem. This is exactly why MOST campgrounds do not have GFI circuits on their power boxes. They don't want to have these issues to deal with. I have a mobile home, and I can't plug my Flagstaff in to the outside GFI plug on my home, but I can and do plug it in to my garage power source, that is not GFI protected. SOLELY my opinion......Randy

• AC current passes between the hot and neutral wires. If it is flowing properly, the difference between the current in the hot wire and in the neutral wire will be near zero. If there is an improper ground situation, such as a hair dryer falling into a bathtub, the current is siphoned off through the new ground situation and the difference between the hot and neutral increases.
  
  

• A GFCI circuit breaker continuously measures the differential current in the circuit branch. Any time there is an improper ground, or ground fault, and the differential reaches a preset threshold, the breaker trips, cutting off all current to that circuit branch. Sometimes, a pulse in the current can create a differential large enough to trip the breaker. There is a lag of several milliseconds between the time the fault occurs and the time it is detected and trips the device. Since a circuit breaker is located farther away than a receptacle, the delay will be increased by the time it take the current to reach the breaker
  
  

Either you have some shorted wires in your plug/cord or you have an excessive power surge when you first plug in your trailer.

Ahhh I totally forgot about that ! GFI'S DO NOT LIKE TO BE FED IN SERIES - IN OTHER WORDS YOU CAN'T PLUG A GFI INTO A GFI ! Arrg never even thought when I read the initial post.

Randy is totally right in that respect.

Thanks for all the help. Took to the dealer, who had winterized it for me, and when they drained all the water out, they forgot to shut off the water heater. So, when I plugged in, the heater coiled burned up, exposing a wire, which kept shorting out the gfi. They also forgot to close the plug underneath, so when they tried adding water, it flowed like a river. They fixed the problem at no cost.

Glad you got it figured out
