If the leds on the panel blinked occasionally that’s 100% not normal. Other RVs DO NOT DO THIS that are properly working. The led only comes on if the fuse is blown or disconnected ( removed) So this means that you ignored a warning of a loose connection ( fuse, wire, PCB solder joint) and almost burned the unit down. The good news is swapping out that whole converter / distribution panel is an easy job that takes about an hour. You can reuse the 120v breakers in the new panel or go get new ones @ HD or Lowe’s. They are standard CH BR home breakers. I would also grab some 10 port wagos as there is a large bundle of ground wires behind the panel probably stuffed into an overflowing ( usually blue ) wire nut. Remove all these and put into a wago or two with a jumper between wagos. A few 3 and 5 port wagos could be useful to replace any wire nutted wires as needed also. Any charred copper must be cut back to shiny and if the wire ends up too short then single wago butt connectors can be used to extend a new wire to fit. 221-420 | WAGO Lever-Nuts® Splicing Connector | for Solid and Stranded Conductors | 10-Conductor with Operating levers | 24-12 AWG | Transparent housing | [Box of 15 Pieces] https://a.co/d/06LdZEU8 All in all you’re lucky. It’s a relatively cheap and easy labor fix. The panel should have a 55 amp converter which will be Auto Detect for Lithium battery upgrade if you don’t already have Li. Turn off and completely remove the shore power cord and Remove the wires at the battery and tape up the ends before before doing any work. Check for any wires that are chafed or burnt and replace as needed. Since we can’t tell if your unit is 30 or 50 amp. Here is both solutions.
