Truck won't start

Hey any and all help is much appreciated.
Yesterday I was unhooking from trailer when another driver started a conversation. Lasted 10 minutes then I made a rookie mistake and had set landing gear and pulled lock but left airlines/pigtail and, u guessed it, ripped it off. The pigtail at the trailer end ripped apart and all the wires were exposed to one another and this caused my truck to die instantly. The dash gauges froze, no power to exterior lights/sleeper/dash. Only a few things work (door light, 4 ways, fridge, cig lighters, and side box lights when open). Roadsquad came out replaced one battery and charged the rest so Its not that. No circuit breakers were triggered except trailer and ecu. When I turn my key there's no crank no click, and no power to radio or dash. I've checked all the fuses and the fuses are fine. There might be some under the dash that I haven't come across yet but idk what else this could be. I have a mechanic helping me he's going to check for replacement ignition relays to see if that's it. If you have any ideas I'm all ears. Also there's no starter circuit in the fuse panel.. but that shouldn't have anything to do with why the lights aren't working just found it weird it wasn't there.

Sorry for the novel

If they are right 5 and 30 amp fuses that are close to the battery bank those are good

 

I have he came earlier, left to get his computer, I'm just waiting for him to get back. Thanks for the help man, I appreciate it

 

U were right, it was the mega fuse. Thanks for the info.

Unfortunately I didn't know what to look for which costed me $1300...


When I read "mega fuses" I was unclear on what the fuses should look like, now I know. Thanks for the info
