2011 jayco arching

[Rsherman3901]

Looking for help with arching fuse.
The fuse for the bunk house, trunk and optional light will arch when I try to put a fuse in.
I believe I've disconnected all the lights on that circuit and it's still arching.
I would appreciate any ideas how to fix the problem.

Thank you,
Roger

Arcing fuses are trying to tell you something is very very wrong.

The most obvious answer is there is a 12V positive wire touching a 12V ground source.

The difficulty will be in tracking it down. A light fixture may have a loose connection on the inside.

You say "bunk house, trunk, and optional light" What does that mean? what fixtures are on the circuit? Are these all ceiling lights? some wall lights?

It will just take some time opening up fixtures and looking for loose connections, or possibly a fixture is grounding out on some aluminum siding.

Either some type of load is still on or you have a short.

Maybe everything isn't turned off?

If the fuse didn't blow, then something is probably still turned on.

Unplug from your 120V to turn off the converter and try again.

I've disconnected all the fixtures.
Still archs.
There is ceiling lights and lights on the bunk slide out.
The bunk house, trunk and optional lights is the label on tge fuse box that is arching.
Thought throwing that out there may help.
All the lights on that circuit has been replaced with new.

Unplug the camper from the pole?

That slide-out wiring has to flex every time the slide is extended. That may be a prime place to investigate.

Then that suggests the issue is in wiring, not fixtures, unless tight quarters has a positive terminal grounding out somewhere.
Has there been any non-factory screws installed anywhere that might have pierced a wire harness?

Just some suggestions.....Roger
