No DC Power

Nothing comes on without shore power except both slides and the landing gear.

2012 Rockwood 8281SS

I never thought about it, but this does not seem right. I should be able to at least operate lights without shore power.

Is there a switch somewhere? Like I said, I can move the slides and landing gear.

Is there a battery disconnect switch for a solenoid? If not there should be a master fuse or circuit breaker up close to the battery on the tongue. The slides and jacks come direct from the battery with separate current limit devices. Usually these are self resetting.

I would start by locating the braker/fuse box. If the main breaker isn't tripped, check each one - plus all fuses.

Rethinking you orig. If the converter will supply all loads in the fuse panel, this would be simiar to dead batteries. Since bigger loads still work direct from the battery, it must be good. Only thing left is the cable feeding the fuse panel and all "hotel" 12volt loads must be open. Believe all battery powered centers begin with a large fuse or man/auto breaker close to the source-battery. Maybe located on the "wall" close to the batteries or on protected structure very close by. Got a meter? Connect the black side to frame or ground and use the red starting at + on battery and check every terminal on the red cable leading to panel.

There may be an in-line fuse off the battery. There are likely multiple wires connected to the battery (or branched off somewhere). The supplies for the slide and landing gear are obviously fine, but there may be another wire supplying the the rest of the 12V system - the inline fuse on this one may be blown.

Thank you for your replies.

I will unplug tomorrow and check the all the connections and incoming terminals, but no fuses are blown on the main feed. It's a fifth wheel, so the battery is inside the front compartment and no bypass switch.

Ok,, soI measure voltage and get nothing at the fuse box. The battery has a great charge. The solenoid shows no loss, but after that...the cable goes up into the trailer and becomes impossible to trace.

Does anyone know where a disconnect or fuse could be in this model?

[VinceU]

Volt check at fuse panel input lug ? Also now can check return side black cable for continuity to frame, even back to battery. Gittin warmer.......

[Derekcan]

Yes, everything around the battery checks good. It's some between the entrance into the trailer walls and the panel that has no juice.

$50 later.....

Dealer found the issue. There is a circuit breaker (thats what they call it) inside the 5th wheel hitch on the solenoid there....impossible to see unless you know what you are looking for. Tiny little black button resets. I looked for hours and never would have found it.

If you ever have this issue, this is a possible solution.

Thank you for all your posts in response.

Picture of this is attached! Picture is rotated to see the button simpler. This would be directly overhead looking at the bottom of the two nubs.

this usually happens when someone reverses the battery wires.
on travel trailers, this breaker is along the A-frame of the tongue.

Just wanted to say Thank You!
I have a 2008 8240SS and it has two 12volt power breakers with the small black button reset. One in the fifth wheel tongue and one in the forward box right next to the batteries. After having my brakes worked on in Oregon I have had no 12volt power. It wasn't reasonable to pull it back to the other coast for repairs and I was so not looking forwards to paying someone to hunt down the problem... or replacing my inverter ... so many expensive options were weighing heavy on my mind and it was two silly teeny tiny buttons!
You rock!
Thank you, thank you, thank you!!!!!
