Attached picture is of the DC fuse panel which is vertically mounted behind the passenger seat (just like the 1978/9 Argosy.)
I have found a 10 amp drain to the house batteries! Circuit 7 is the culprit. I pulled the fuse to stop the drain, but cannot figure out what is the cause. (Airstream Manuals do not identify where the individual DC circuits go. The purple wire does go to the galley overhead lights, but must also power something else, as these lights I don't think could draw 10 amps.
Any insights? Thanks.

Just a guess, but possibly the kitchen exhaust fan is stuck and on. You don't know it is on as it is not running. Another possibility is an overhead vent fan, or furnace fan, any one of which could be frozen, but drawing current. The water pump motor is another possibility.

Leave the fuse out. When you find something that doesn't work, that's it!

Not sure on Argosy MH's...
Bathroom fan seized?

Thanks for your reply idroba! With the fuse out, all the items you mentioned work fine, obviously running on other circuits. I wonder what else it could be?
I suspect the rusted-out non-working furnace. Just need to figure out how to isolate and identify. I would love a schematic!

Thanks drboyd:
That's what I will do. I'll start with the furnace. I smell a rat.

Thanks Keyair, I will check that.
Seems far down the line, but would be capable I guess of drawing 10 amps. I also suspect the old Suburban furnace. Wish I had a schematic!

That's exactly what I had....mice. My issue was in the front passenger side wheel well. A rodent built a nice house there and chewed my wires. The wires also sit on a C-channel and wear at that spot. The wiring harness left the 12v panel, goes OUTSIDE into the wheel well, and then re-enters the wall. The wire are unprotected for that short distance. Maybe they changed it for the Airstream brand! They learned as they went with the Argosy prototypes!

Compartment lights??

Could be.
