Mystery Fuse does What?... to Me. 2019 Oliver Elite II

[BoondockingAirstream]

This fuse is under the street side bed and half way up the right side among other wiring hardware.  What does this Fuse Protect?  What is it called?

I am trying to hunt down an obscure reason why my Trailer Brakes are not recognized, when my 2019 Oliver Elite II to my 2016 F350 Diesel.  I plug in and when press the F350 Brakes... disconnected.  My 2019 Airstream has no issue with the Brake Controller. So it is the Oliver and some wiring issue?

Pull the Trailer Disconnect when spinning wheels on either side... they immediately lock up firmly.  Insert the Pin and power is disconnected and free wheeling with no effort.

Have a Post on Oliver #448 and trying to find the... obscure... problem, but following wiring using a flashlight is the best I can do at the moment.

This is the fuse for the CO2 detector. I needed to find it in the middle of the night at Camp Oliver the day we took delivery of Curiosity! 😵‍💫

Steve Thanks.  Now everyone knows.  This is information that is often found by those with experience!

Learning one 'fuse' at a time.  I will plug it back.

My Electric Brakes seem to have a Fuse issue or Wire inside the Oliver.   Maybe  a simple fuse, reset or something that is between the operating brakes and 7 pin plug.  Or a wire not making contact in a wire bundle under the table or bed access areas.

Wow.  Again that was quick.

How About THIS ONE, under the second seat at Table.  No fuse inside this RED Plastic.

Based upon its location, I would surmise that fuse to be for the portable solar input connector located mid-streetside, typically rated for a maximum of 10 amps.

I have a 2019 and don’t have a fuse for zamp there.  Our zamp fuse holder looks like that but is located in street side rear area by the rear wheel well.  Our zamp connecter is on the side of the trailer just past the battery box.  Maybe your zamp connector is near that fuse. 
 

Do you have a composting toilet?  Did you follow the wires & look where the wires connect?

Followed with a second mystery RED fuse holder... and... sharp Oliver owners were right.  The exterior plug for portable Solar Panel fuse.  No sure why no fuse, but the two Solar Panels on roof... keep us 100% charged.

I am sure more odd items will be discovered while looking for a loose Electric Brake connection.

Do have a composting toilet.  Do not use the composting side as we have a Shovel, when Off the Grid.  Pack out toilet tissue and fertilize the Pine Forest?  Wife finds the composting toilet... wonderful.  I am the Urine Dumper onto the Plains or the Forest.  Sure beats a Black Tank and all of the possible issues with those.  It came with the Oliver and still have unopened coconut and whatever else.  Always spotless and no odor. What works for the wife,  makes me happy.  🙂

So did you find the red one up under the dinette was for the composting toilet and red one in rear wheel well for zamp?

The Red Plug without a fuse under the seat, facing towards the Bathroom Door Mirror... had wires going UP and attached to the interior side wall and out.  Went out and discovered... Yep... the two pin plug for a Solar Panel.  At least I now know, had I attached my two pin plug to my 'mobile' 100w Solar Panel... it would not work as well.  Until I find out what the hell kind of fuse it uses it would not work.

Am I getting too much background radiation from the Volcanics of Nevada?  My ears ring and I cannot find a loose wire buried within our Oliver.  When my Travel Trailer Book is written... I will buy and autograph my own first and only copy printed.

Somehow I must have had a woodpecker pecking my brain at birth... looking for a loose wire connection, somewhere unknown, to discover THE WIRE bundled with the Electric Brakes... and discover all of this other stuff as byproducts.  I would loved to have done some OSHA Inspections... at some assembly plants.  That is how in 1970 we learned about... Safety Inspections and which businesses were a Total Disaster and avoid personally.  

The Owners/Managers were always nice and respectful... when I handed them my State Business Card.  No one in Wyoming called out "Get A Rope".

I looked at the mirror attached to the bathroom door, and saw this handsome Neanderthal looking at me.  Opened the door, and no one was in the Bathroom.  The mirror was faulty and going onto my list, as well.

To be Fair. The lights were dim. Gotta figure that out, as well? 🙂
