Initially, I just pulled the likely fuses for a visual inspection. When
that came up empty, I used my Horrible Fright ohm meter to confirm
continuity between the two terminals of the fuses. I've swapped in known
good fuses to no avail. I have checked (at least visually) every fuse I can
locate. I am 99% certain there must be another fuse somewhere. If you have
experience working on motorhomes you'll know anything is possible...
