No battery power.

[Pursell]

Getting ready to head home this afternoon, brought in the slides, locked up and went to raise the jacks and nothing worked. Slides still worked, nothing else, no water pump no power anywhere. Yet the battery's are fully charged. Had to plug into the the truck to get the jacks up. Get home and used shore power to get thing working, battery switch is on and working. We where using the inverter to watch a movie, right before we left, but that should on effect anything has it was being used as shore power. Is there a main fuse or breaker I am not aware of? If so where would it be located? The unit is a Forest River super light, it is one year old.

Generally, your electric tongue jack has an inline fuse and is wired separately by it's own wire directly to one of your batteries. Follow the wire from the jack back to the battery and you may find your problem.
Let us know what you find.

You don't say what Model?? Check the two high current 30-40A fuses in the converter. If they blow, you will not have power from Battery to fuse panel.
