Hi there. I'm new to the Airstream scene, I'm glad this site exists. I'm dealing with, I believe, a
1966 Sovereign. The electrical system was fine until recently, then it sat for a few months and now none of the 12-volt fixtures or motors work. I'm trying to track down the electrical fault, but my Airstream knowledge is limited.
Plugged into external 110 AC, all the AC outlets work fine. I tested the circuit breaker box and there is current on all four circuits. There is a DC power supply plugged into an AC outlet near the rear service hatch, but it is screwed to the floor in an inconvenient location behind some plumbing and the toilet. Hard to get to. There are 4 DC fuses that look like this:

Left two fuses go to the battery leads, which is disconnected. 3rd fuse is carrying 13 volts and change. Nothing on the 4th one. I assume that since I'm reading DC voltage at the fuse that the power supply is good.
Mice were tearing out insulation and building a nest with it. I'm afraid that they chewed through a wire somewhere. Im just not sure what goes where, and none of it seems too obvious or accessible.
Anyone have any ideas about how to troubleshoot something like this, preferably without tearing out the walls? Thanks in advance.
