The USB ports and AC plugs not working on the curbside

[Trailblazers]

My USB ports and AC plugs are not working on the curbside of the trailer (2018 Elite II).  I'm assuming it's a fuse, but I can't find it.  Any guidance would be appreciated.

 

Thanks, Dan

Is the DC plug working - the one over the kitchen area?

[Trailblazers]

No, DC plug is not working either.

Sounds like a 12v fuse but that doesn't explain the 120v outlets...

The USB ports are 12 volts DC (input), the AC outlet is 120 volts AC, they are in no way connected (electrically). You need a basic volt ohm meter so you can do some testing. The AC outlets are all wired together, with a single circuit breaker. You are lucky in that you have real wiring diagrams, they quit supplying them after your year I think.

While you are checking fuses in that panel (at the converter) check all the little brass “ears” that grip the fuse contacts. These DO loosen and can cause intermittent or complete failure. Remove each fuse one at a time, and carefully squeeze the ears together using needle nosed pliers. You should disconnect the batteries first unless you like taking risks…. When reinstalling fuses, push them straight in, do not cock them or you will just loosen those ears again.

That may fix the USB issue, but it has nothing t do with the AC outlet.That may be faulty, it is easy to replace.

Thanks for all the help & feedback.  Would this be the 12V fuse under the dinette?  I've checked that one, but I'm assuming there is another fuse somewhere that controls only the curbside area?  

Correction - my ac on that side does work.  We park the trailer about 30 mins away and I couldn't remember if it was all outlets or just the USB and DC plugs.  My wife (her side of the trailer) thought it was all.  Sorry for the confusion.

I have an 2018 Elite II, hull 354.

This is the directory for the fuses in the attic

Do you have a fuse sub-panel in your attic?

This is the  directory for the fuses under the dinette:

Looks to me like #3 in the attic.

Problem solved, thank you dewdev!  It was the #3 fuse in the attic.  I've owned the trailer for two years and never would have looked in the attic for another fuse panel.  Looked almost everywhere else.  Thanks to everyone!
