Diminished Electrical Output.

[GallivanGM]

I have a 2015 30 ft Flying Cloud with what seems to have diminishing electrical power to all the systems. It is plugged into a 50 amp connection so the unit is getting power, but lights are dim, frig does not want to stay on and I am not sure what to look at first.

Even though you're connected to shore power, does everything turn off when you switch your "use/store" switch to the "store" position? If so, then it sounds like your converter is not working and you happen to be running on your batteries. Perhaps the fuse to the converter is blown or the converter itself isn't working.

What does your battery voltage readout?

is your electrical source working properly.? Where are you plugged in and to what?

I had this but not the entire rig and it was a loose fuse.

Hi

Lights, fridge, and various other items in the trailer run on 12VDC. That comes off your batter. It normally gets recharged by your converter (from shore power) or your solar setup (if you have one).

The microwave, AC units, and entertainment system normally run off of the 120V shore power. Some 120V stuff *can* run off of the inverter. That's not a good idea if you have shore power.

First thing to check is to see if you actually have shore power. A simple/cheap outlet tester lives in the socket by the stove on my trailer. That makes it really easy to tell if shore power is there or not.

Assuming shore power is present, next thing to check is the converter. A good check is to put a multimeter on the battery and see if it is up > 13.5V with shore power connected. If it's not, either the battery is in big trouble or the converter is not workin properly. The converter can indeed blow out. It also can shut down if a breaker trips.

In any case, you should have some way to monitor battery voltage. If you have solar, the control panel is a good way to do this. If you have no solar, the other panel is ok. A multimeter is best if you suspect a problem. If you get below 12V, that's not good.

Lots of possibilities
