Update in the morning light....Have an interesting problem with a 2013 DK45HST. Halfway through spraying last night I had to stop and reload the sprayer, eat, get sidetracked on something else and then came back to the tractor to complete the spray job. Fire up the tractor and find there is no working AC and several other electrical accessories are not working but some are. There is a fuse panel next to the seat. One side of the panel has power but the other side does not. Each side appears to be supplied by different wires. One side supplies power to the Wipers, radio, and cab dome light which all have power. The other side (no power) of the panel supplies power to the AC, 12v lighter, work lights and I cant remember what else.
Here is a pic of the wiring under the fuse panel. Looking at the lower half I am guessing the heavy red wire is the inbound supply to that side of the panel, the reddish orange heavy line is the AC supply and then the others feed the 12v outlet, lights and etc.
Not sure where that heavy red wire goes as I believe that is the main feed of power. When I crawl under the tractor there are 4 wiring harnesses and all are enclosed in shielding and most definitely a sob to reach. I am wondering if there a fuse inline somewhere else between this point and the alternator/battery.
I should add the tractor still starts and there is power to the headlights, signal lights, dashboard so I don't think its the slo-blow fuse but thats just a guess.
Any suggestions?

Is it possible there is a maxifuse or relay protecting each of the two sides of the fuse panel? Odd that one whole side of panel is dead. What is the small gauge wire under the panel? How is your sprayer wired into the tractor...on the dead side of the panel?

That's about as useful as a picture of the grass in your yard.
Get a wiring diagram and find out how the fuses are fed. I bet there's a relay, master fuse or fusible link somewhere. Could be a critter had lunch on your wiring while you were away.

The little red wire is to my rear cam and its tied into the power for the wiper blades and also the switches for the solenoid valves on the spray. The actual sprayer is driven by the PTO. So thankfully since that side of the fuse panel is still energized i was able to complete the job, but I need AC and power for the respirator when insecticide season arrives.

Not much grass as we have been in a drought the last 6 weeks without a drop of rain. The OM has nothing so not even sure where to find a electrical schematic. I'll have to contact a dealer and see if they can figure it out but of course the closest one has since gone out of business...That's about as useful as a picture of the grass in your yard.

For those following along here is what we finally found:
Spent 3 hours starting from the battery and working to the back of the tractor checking every plug assembly, fuse, switch and relay. We tested each section for continuity, voltage and ground. Everythign checked out fine until we got past what we thought was the last connection before disappearing up into the wheel well to the fuse panel in question. We just could not get continuity in that last section….hmmm what could it be? So we climbed all around the back of the cab and noticed behind the rear window washer fluid tank was yet another wiring harness. When we went to pull it apart it to check it, it nearly came apart in our hands. The plug was loose and had melted a bit and was cracked. Really could it be that easy…well we tested the conductivity of the wire to the fuse panel and finally bingo, we had the wire that leads to the fuse bus! So cleaned up the connector and secured it with electrical tape. Turned on the key and vrooom the AC fired up full blast. So the last wiring harness connector is all the way in the back of the tractor and then comes back 180 degrees forward to the fuse panel. I’d like to meet the electrical system designer and frustrate his/her life for 4-5 days!

Im sure its that way so they could lift off the cab. Disconnect the harness and lift.
