Melted fuse holder.

There was a reason that the fuse panel melted. HEAT. BAD CONNECTION SHORT. You need to find the source of the problem before you do anything. If you have the resources,Changing the fuse panel is NOT a BAD IDEA. The new fuses are easier to come by.

Thanks Mike
The original fuse panel was rusted and corroded pretty bad.I cleaned it all up but would feel better with new set up.

In our trailer, the fuse box itself was the cause for burnt wires.

The fuse clips and connections had lost their temper after corroding quietly in the damp dark under the bathtub for nearly forty years, to the point where the resistance through the fuse panel, at least on two circuits, raised to the point where the heat from resistance caused actual damage to the wire connecting to them was crispy burnt.

The two fuses on these circuits blew regularly from this phenomenon as well.

Here's a couple of photos showing the damaged wiring.

I'm with you Aage, I have the same problem.I figured replacing everything would be best.I just need to figure out the best way to do it.

So I decided to replace my noisy Univolt with a 60amp Boondocker converter from best converter. Working with electrical is not my favorite thing for sure so I researched as much as possible here on the forums.
Getting to the converter was more work than I expected. I had to remove the gaucho which gave me access to the shroud enclosing the Univolt.Once that was removed I discover another shroud,this one is insulated. Finally I can see the noisy culprit but it's a magnatek not Univolt,

Looks like I have some some water damage to the floor by the battery boxes which by the way need to be replaced as well.








The trailer plug receptacle is original and since I have access to it I might as well replace it.The spring loaded cover is about to break anyways.
It's funny how one job turns into many
So I have the converter installed and working properly, proud of myself on that one.It was actually very easy.
