Any help would be great. I just picked up a 2015 cxu613 daycab a few weeks ago. No issues drove truck form Ia to La. Due to a lil rust had frame painted. Picked it up and parked outside shop a week ago. Went in to crank up this morning nothing. No power absolutely nothing. Checked all the fuses good. Checked the batteries n found connector to the battery post for the mega fuse wire was broken. Replaced still nothing. Check the batteries they were all good. Check fuse panel on top of dash no power. Check power at firewall going into even ecdm fire in but not into the panel. I’m completely lost any help would be helpful
