1586 cab electrical

The weather warmed up here and I was able to move the throttle control and give her a run. Appreciate the help on that simple issue!

Having a cab with AC, wipers, AM/FM radio etc is pretty sweet but once I got her home all of these things stopped working. I thought there must be a blown fuse and would get around to finding and replacing but then they all started working again. It is an all or nothing kind of thing. Everything either works or it doesn't. Currently not working again. SO...wondering if there is some type of self resetting breaker in there someplace or what? If so, is it something that could be going bad or should I be tracing wires looking for a mouse nest or similar? Around here most electrical weirdness can be traced to rodents.
 
It seems like there is a cab relay behind the door in front of your feet, I think the fuses are in there too? When it goes bad the tractor will fire up but the electrics in the cab are gone, they will often come back on a few times and then it's done. I think you can check it with a jumper wire. Had to change two or three over the lifetime (so far) of my 1086.
 
Flick the key switch on and off a few times and sometimes the relay will kick in. You'll hear it click and everything will start working till next time. Better get a new one in there. Jim
