The following is my response to a post on the
Casita Forum re: a blown fuse:
Just for the info (doesn't seem to apply in this case), in Scamp's wiring there are two additional glass fuses, each 30 Amp. One is located in the
battery box and the other is located in the storage compartment under door side of the front lower bunk (up in upper left hand corner). These fuses protect the main 12VDC wiring from the
battery and the tow vehicle.
The one in the
battery box is subject to corrosion and should be one of the first places to look when something seems to be wrong with the battery, as it affects both charging the battery and feeding the 12VDC system when the umbilical cord is disconnected and the converter is not plugged into 120VAC shore power.
I expect that
Casita will have a similar arrangement.

PS It just occurred to me that IF the circuit in question is being fed from the 'filtered' part of the converter panel, then the battery IS involved and the other circuits may look fine if the converter is plugged in to 120VAC.
If you unplug the converter from 120VAC and NOTHING works, look for a blown battery fuse (altho I would expect the 15Amp converter fuse to have blown before the 30Amp battery fuse).
