Any advice before I take the truck to someone?

What about _your_ relay? Up fitter 5 is like 5 or 10 amps tops. You’re not running a compressor off up fitter 5 with no relay are you?

I don't know shit about electrical. It was all done before I bought that truck. I wouldn't even know how to check it with all this wiring. Truck has a air comp, chase rack, lights, retractable side boards, winch, amp, stereo, ****** radar detector.....just shit all over.

Also found this. 40amp fuse for what I think it running board lights.

Why does it look like that wire is too small for a 40 amp fuse?

JAYZUS!!!!

40a would need 10ga. multi-strand feed. If you fried that 40a fuse and heat damaged the housing, something is very wrong in that circuit.

Did you buy it for $30k in “like new” condition from a guy named Moe?

Do the retractable side boards really draw that much power ? I’ve never had them so needing to know for what’s next.
This would be a very pricey diagnosis, so I strongly recommend you brush up on auto electric. If things were done to some sort of standard, red should go to positive, black should go to ground; negative. You could see that kind of damage in a circuit that is overtaxed or that’s damaged.

one at a time, trace your wires from home runs(battery) to the accessories. Your air compressor is almost certainly using a relay. I have a Viair rated for 33’s and it’s a solid 20a draw and it’s not even that big.

I spy some 2ga. or larger going into the big fuse block, some 8 gauge, a couple B/D harnesses - probably 15 or 20 amp, and that red fuse holder looks like it could be 10ga.
you should definitely familiarize yourself with where things go.

the blown fuse, do not reconnect that.
1- make sure you have power on the other side- going to the battery. trace the red wire coming out of there to the accessory. Look for a loose connection, bare wire, broken wire, etc. that will also cause an overheat and blow the fuse.

I'd offer to help if you were a bit closer.

Are there any FRF members in the area that could look into this for SCAR?

I may have a buddy who knows a guy who could look all over it. Despite working in this manner for years, I prob need it checked over.

As far as the running boards, I removed them but left the wire as it was tied into the AMP lights. It's actually a connector that runs to the OBD port.
