Your trailer lights all run on 12v.

It sounds like your battery isn't charging while you're trailer is plugged in. You have either a univolt or some other charger in your Airstream. Check to see if it's working. If it's not, it's either dead or it's not getting power from the main fuse panel. You can check this by simply checking the univolt/charger output to the battery with a voltmeter. It should be reading about 14volts while charging.

Take a 12 volt tail light bulb and solder a wire on the side and on the bottom connection. Then solder alligator clips to the wires. Then hook this between the battery and one battery cable. If everything is off, the light will be off. If the light is on, go around and explore the trailer to find out what is using power. You can use a volt meter for this but you can see the light easier from far away.


Good luck!
