Where is the main fuse

Currently my 400 is stuck in the woods with no power going to the ignition switch.
Background: I was having to turn the key on and off several times before I could get the dash panel to light up and the fuel pump to prime. Figured it was corrosion in the switch. It finally stopped working all together. I was getting power to the switch but not through it. Replaced with an on/off toggle switch and it worked perfectly.
Yesterday it slipped off the trail and wouldn't pull itself out. I tried to activate the four wheel drive and it died just like I had hit the kill switch. Now there is no power going to the switch. The fuses in the fuse box seem to be fine. Solenoid works, battery is charged, but no display on dash and fuel pump doesn't prime. Is there's main fuse? What else could it be?

Did you ever get a response? I am having the same problem with my 400. I found the fuse box under the front hood but is there a main fuse closer to the battery?
