Am having problems with an 07 34N hurricane

[Norman Sachnik]

My entire Coach DC power cut off. I have contacted Thor tech service and have found that they do not know the location of a overload relay or fuse to restore
the power.

I have given up looking at every known location and still have only power produced by the AC to DC converter.

I do know that the power is lost from the battery compartment onward

HELP
