My 01 Rancher ES is immediately blowing the 10 amp fuse when I turn on the ignition key.  When I unplug the rear control unit, it does not blow the fuse.  I have unplugged the lights, engine kill switch and carb heater it still blows the fuse.  I put a lead from my meter on the space where the ignition wire comes into control unit plug and touch the other lead to the frame and it reads "0".  I have looked at the wiring harness and cannot find a short.  Any suggestions?  While the control unit is uplugged everything else works fine....what gives?  Thanks..Solohunter
