I think your first order of business is to get the batteries charged or replaced.
As I understand it, some converters will not power the lights etc. with dead batteries.
And it may not charge them up from the shore power.
Try a regular battery charger to see if they will come up. If not replace them before more trouble shooting.
At least get your slides and lights working. Some other items will require battery power also like air conditinoer, heater control board, reefer.
