I was driving the mule and it just quit. After checking for the problem I found that the 30 amp main fuse was blown. I replaced the fuse and as soon as I turned the key, it blew again. I have found that one side of the fuse terminal is grounded. I have traced the ground back through the switch and I have hit a road block. I can find anything that would be causing a ground on the acc side of the switch. I think I have moved every wire and unplugged everything I can find in the front and it's still grounded. Acts like its the brown wire that is grounded.

 

Hi,
Q. , Is This a Diesel ??
If it Is,, First try Removing the wire off the glow plug , Replace the fuse ,
(try it , But Do Not Start ! ) If The Fuse Does NOT "blow " , Then one or more of the " Glow Plugs " Are ,,, Burned / Shorted Out .
If the Mule is still Blowing the fuse, Remove the Positive (+) wire off the Alternator , Try again , If the Fuse holds ( No Blow - OK ) The Alternator is Shorted Out . Last ,,, Check The "" Power Outlet Socket "" On the Dashboard ..

Hope This Helps,
Later,

9 years later I have the same problem and find this thread.
perfect diagnosis- bypassed the bad glow plug and back in business. Will order the replacement and get all three back in working order but this time of year we are good to go until it arrives.
thank You!!
