Weekend Warrior Generator vs Battery power

That must be something that was moved in the 2007 models. My 2006 FB2200 had the DC fuse panel, cutoff, and converter in the cord storage area.

AC:
The Weekend Warrior did not use a transfer switch to route power. In the cord compartment you will find a 50A outlet that is the generator output - Plugging in the AC cord will power the trailer by generator.

DC:
In the cord compartment is the master cutoff switch (like Lincster posted). This will disable the battery supply on the trailer except for generator and tongue jack. If you are still plugged into your tow vehicle, you may continue to get power from it even with the master off.

In my 2007 WW, the 12v dc cutoff is under the refrigerator compartment, next to the converter.
I searched for that switch for weeks... lol.

I only have the shore power cord and genny receptacle in the outside compartment being talked about...

Plugging the the trailer connector to the tow vehicle and fast idling the engine can bring the batteries back up in the trailer enough to start the generator. You can also use jumper cables between the tow vehicle battery and trailer to charge the batteries or start the generator.

First you will need to identify which switches you moved, so we can help troubleshoot your lack of DC.

In the same compartment that you have your main plug, the one you use to plug into shore power, there is a silver "switch" that you can push/pull. That is your main power disconnect, pull it out to get power to everything.

Sounds like your battery master disconnect is shut off. When you start the genset, it powers your converter which provides 12V and runs your trailer. Normally when your genset is shut down and your converter looses 120V your rig will run on battery. However if the batter disconnect is shut off, it's lights out. So, if your only getting 12V with the generator running, that means it's coming from the converter and not the batteries. Look for this and see if it's turned on:



Or this:

Sounds like a weird problem.

Look for a tripped 40 amp circuit breaker between the battery and the fuse panel. I am not to far away from you - I could take a look at it for you if you like, free of charge. I am near Fairview exit of I84. Near Camping World. I would be willing to drive over and take a look at your WW.
