93 Terry 26ft lease trailer. Got to camp today to find my trailers inside and outside lights, water pump and stove exhaust fan not working. The outlets inside and out all work as do the inside wall lights, microwave and refr. Tried killing the breaker at the pole, no go,then inside breakers, no go. Also replaced the 3 fuses marked "lights and the "accessories", still no go. I'm stumped. Any ideas? BTW I'm back home now so any testing will have to come later. Thanks in advance.

Inverter gone bad? Does it have a reset switch?

Couldn't get the YouTube video that I think I needed to load on my phone at camp, figured WTH, I was tired and the refrigerator was still working so I came home. Just viewed the video and it says there is a 'Manuel breaker" on the frame after the battery that can be reset, that may be my problem. Maybe I can get back out there next weekend.

Sounds like a bad inverter or a dead battery. I think all of the items you described are battery/DC operated.

No batteries, just shore power. Maybe the converter?

First disconnect the battery, they try resetting the inverted. If the battery has gone dead-short, it will make the inverted trip.

If that does not work, try plugging the trailer brake connector back in and leave the engine in the vehicle running. If your lights and stuff start working, it verifies what the other folks have said...your battery is toast and your inverter is not running.

Thanks, but this thing hasn't had a battery hooked up the 5--6 years I've owned it. :Plugged into the pole only .

The converter changes 120v to 12v. Sounds like all your 120v is working, but 12v is out. Check the converter. Sometimes they'll have fuses you can replace, or the converter simply has gone bad. Simple enough to check converter output with a good volt meter.

What he said. Been there, done that.

I know this may start a debate, but I have always kept a 12-volt battery working in my trailer for a couple of reasons. First, even though it isn't an absolute must, I want my inverter to work as a battery charger rather than a 12-volt power supply. Just like the 12-volt system in a vehicle, the battery provides the vast majority of the power while the alternator just keeps a small amount of current to keep it charged up. With no battery, the entire current load of whatever 12-volt lights and other equipment you run is put on the inverter. While some might claim the load isn't excessive, I know my lights are much brighter when I have a good battery than when they are powered only from the inverter. I also like the convenience of having lights during power outages, or when I don't have my trailer plugged into my power pole. I always unplug it before leaving for safety reasons. I also installed a solar panel to keep the battery charged since the trailer is used mostly on weekends.

What Texas Dan said.
My experience mirrors his exactly.

I totally agree and do the same

One other thing on the inverter. The inverter on my old Fleetwood was plugged into an A/C outlet and it was located on the floor under the fridge next to the main breaker panel. The first time I moved my trailer, the plug came loose and eventually everything died when my battery ran dead. Since you are on shore power only, maybe your inverter came unplugged or the A/C power line to the inverter died somewhere. That or the inverter finally bit the dust. If you need to get a new one, here's a link to the one I bought when mine finally died. It took all of 20 minutes to swap out the old one with the new one.

That's the same one I bought. Easy access to mine so took about 5 min to swap out, runs like a champ. No more issues.

Never kept a good battery in any of our TT's. Like others would suspect the inverter or its circuit breaker/fuse

Team, we need to get our terminology correct. In this case, words matter A LOT, and honestly I'd be pretty ticked if I bought a fairly expensive inverter when I needed a converter, or vice versa.

As mentioned earlier, the CONverter changes 120v to 12v and is what charges your battery and provides juice to your 12v systems. The INverter changes 12v to120v and normally will have a switch you activate to begin inverting, like when you want to watch TV or brew a cup of coffee when you're boondocking and not connected to 120v AC shore power. I expect there are only a few outlets connected to the inverter in your RV and should be marked. These are two very different things and I'm sure not every RV has an INverter. Your RV has two different electrical systems (12v and120v). Some appliances can run off of both like the fridge...12v/propane or 120v when connected to shore power. When connected to shore power, and assuming your CONverter is properly sized (say, 55-60 amps for a 50 amp service RV), whether a battery is connected at all is irrelevant. If you overload your CONverter, of course you can smoke it pretty easily. I just pulled my RV (50 am service) out of storage after three years. We did return to the states several times during those three years and camped in the trailer without ever reinstalling the batteries. We used both ACs, all lights and appliances (many all at the same time) and never once had any issues supplying either 12v or 120v.

Again, a good volt meter will tell you whether each DIFFERENT device is CONverting or INverting correctly.

Rant off.

Just back from the lease. Bad converter was the culprit. Bought a new one off the interweb, hooked it up, and what ya know...power is back on. Nice thing is this one is silent, the old one's fan ran constantly. Thanks everyone.

Just glad rats didn’t get into the wiring...

Very well stated Sir

The fan on mine only runs when the battery is low and the converter is having to charge it and power all the 12-volt lights. After it gets the battery charged back up, it turns off.

Since adding a new battery and a solar charger to keep it charged during those long periods when I'm not there, I never hear the fan.
