Can't get electric to come on from battery ?

Help !

I'm a first time Airstream owner that just bought a 2000 Excella 30 ft. last night.

My question is this: I can get my Airstream's electrical devices to work when it's plugged in my home, but when I unplug nothing works (ex: the Superjack)

Is there a switch I have to hit or something to change over to battery power ?

Any help much appreciated !

Yes, there is a battery disconnect switch, and if your floor plan has a couch in the front, it is most likely under the couch when the big drawer is pulled out.

If your tongue jack works only when the trailer is plugged into the tow vehicle, your trailer battery could be totally shot, or disconnected.

Airstream Electrical

Hello windvale. When you are pluged into shore power (120VAC) the plugs in the trailer will be alive and you can plug anything into them that requires 120 VAC (household stuff). When you are not connected to shore power these plugs are dead unless you have an inverter that inverts 12VDC to 120VAC.
The lights and appliance PCBs require 12VDC to operate and operate off the battery.
When you say nothing works except when you are connected to shore power it sounds like you have a dead battery or no battery at all.
The fact that everything operates when connected to shore power is that there is a converter in the trailer that converts 120VAC to 12VDC for any 12VDC needs and also to charge the battery, but when you disconnect shore power that converter supplied 12VDC goes away and the battery now supplies the 12VDC.
First I would check and make sure you have a good charged battery and the battery disconnect switch is on.
Good luck nm1oqrz

If the jack works you batteries are Good.
The switch is a rotary type usually behind the right side back of the coach on a small deck below the front window. That switch should be clearly mark on and off.

If it is not the switch someone has disconnected the batteries either at the batteries or on the bus bar in the 12 volt panel, highly unlikely but an electrical disconnect point so I have to mention it.

In my 30', the disconnect switch is near the floor, on the left side of the couch, as you're looking at the couch.
