2003 yamaha kodiak 400 2x4 blows 30 amo fuse when key turned on

[STEP MONSTER]

as soon as key is turned on 30 amp fuse blows. replaced battery & starter relay. no luck.

There is obviously a dead short.  Was anything new wired into the bike ? Or maybe an old plow wire that was left there ? Accessories that were incorrectly installed or left on the bike that’s causing it ? 

I would start unplugging the plugs on the starter relay and any other plugs you have. Put a new fuse in and look for when the fuse pops as you re connect each plug.  Start there and see if you can trace it back.  

Also look for anything that stands out like a bundle of tape on the harness that may have been touched or any damage that may have been caused by maybe someone that put a ratchet strap on the fram over a part of the wiring harness and crushed it.  

Process of elimination. 

Get a few extra fuses!!!!

@Frank Angerano makes a good point, check over your wiring get some extra fuses! Something is shorting out.
