Today I learned the location of the fuse for the stairwell light on my Barth.

I did not find it right away. I was about to put on the coveralls and go underneath to trace the wire, but took a flyer and checked the OEM chassis fuse block under the dash.

The stairwell light is a little license plate light that gets its power from a big heavy orange wire that is fused by a 20 amp fuse in the fuse block under the dash. I have no idea what else it powers, but it is not the step motor.

Anybody else know what is on that 20 amp line besides the stairwell light? I find it passing strange to find an RV circuit powered by an OEM chassis fuse.
