Welcome to the forum Buzz19, look under the entry steps(both) for fuses. After that check under a panel under the bed, more fuses are located there. When I say under the bed, raise the bed and then there is a panel usually held in with phillip head screws. All of the interoir lights are fused there. There is also a 30amp 12volt fuse in the battery compartment that controls the "battery switch" button, if this fuse is blown nothing 12v inside of coach will work.
