Did you put a meter on your battery
? Do you have any power?
Do you have a florescent light
in your kitchen that runs only on shore power only - does it work?
Do you have a converter? You may find some fuses inside the converter box that may be blown assuming you have already checked the two inline fuses - one at the battery
and one just inside the trailer where the wiring comes into the trailer on the passenger side. Often inside the hatch behind the wall covering.
