Unidentified blown fuse

[drillagent]

We recently took our 2012 3750FL in to have the roof fabric replaced. First thing they did was turn off the battery disconnect. I haven’t touched that in probably seven years. When we got it back to the campground, there was a blown fuse. Everything in the rig works. Every AC, fan, outlet, light, etc. I can turn off the battery disconnect and replace the fuse. But as soon as I turn it back on, out it goes. I also don’t understand the abbreviations on the fuse box. Attached is a photo of the fuse list. The blown fuse is the far left, top row. Can anybody tell me what that is? Can anybody tell what each one is? Thanks

Dollar to donuts that is a 12V fuse for the AC. Which fits as the roof was replaced and that requires removing the AC to do so

Guessing "ODS" Opposite Door Side?
Left side Flood light?
Maybe they drove a staple through the wire when putting the new roof on?
Remove your control panel and pull the wires to your left side Flood light. Turn the battery disconnect switch on and see if the fuse blows.
If it does, reconnect the wires.
Disconnect the next set of lighting wires, replace the fuse etc.....
