As others have noted, you seem to have an "open" on the wire path from converter to battery. You say the battery fuse is ok. So there has to be another open in that path. You say it is not the disconnect switch. So what does that leave? Perhaps a loose connection at the battery wire lugs on the fuse panel?
The jacks and slide have direct connection to the battery so they will work even if the battery juice can't get to the fuse panel and be charged from the converter (also on the fuse panel.)
You could try to run the jacks from the converter (shore power needed) with no battery to see if there is indeed an open in the path. You take the battery wires off and clamp the two red wires together that were on the battery pos post so there is still a path from converter to jacks.
You need to find the open with a voltmeter at each end of every item in the path till you no longer get 12.x battery voltage. That's your culprit.
