Battery DEAD.......converter in overload mode (shut down due to high amp draw for dead batteries)
That is one possibility.
Knowing MY would help. Over the years converters/chargers come with several different technologies.
Older would run RV on 12 VAC and only small circuit with DC power would go to radio and battery charging. At the time refrigerators would work with no electric power.
Later converters have one circuit for RV and other for battery charging and floating switch will send the power where it is needed.
Than you will find converters who are actually chargers paralleled to the battery.
So when battery shortening older converters would not affect lights in RV, the dead battery can overload newer converters.
Always disconnect dead battery before turning the power on.
Usually chargers can take such overload, but this it testing your luck.
My camper will operate with no battery on 40 amp converter, but trying using the jacks, it will power 1 only.
Once I try to move all 4 jacks at the same time - converter will go to overload.
