Welcome to iRV2 .

I don't know how common the set up on my Freightliner chassis is ; BUT; within 3 feet of the chassis and coach batteries at the battery tray ( rear of the coach ) in the positive cable is a 135 amp fuse , that protects the cable from the rear of the coach to the front, where all the loads attach to a power stud.
These fuses are mounted to the frame behind the battery tray. Would be worth a look to see if your's is similar.
First picture is the frame mounted fuses.
Second is the power stud at the front of the coach, left side with red cable attached. This is the coach battery power , chassis battery is similar on the other side of the fire wall, not visible in this picture.

Is your 1993 HR a gas or a DP? What model?

I have a 1995 HR Endeavor LE gas model, also a 36 foot. It has a tag axle.

I was fortunate enough to receive a full set of manuals with the thing, which I found includes a bunch of wiring diagrams for various models.

If you think it would help you any, I'd be happy to share. I scanned the entire manual so I have the whole thing as electronic files.

Let me know if you think it would help you at all.

If you check around inverter or converter their is probably a main fuse their (that's where the one is on brother's coach )

I'd locate the battery used to start the engine (main) and work my way toward the fuse box with a test light from there. When a whole fuse box is down like that, it's rarely anything too complex.
