Long story short I tried hooking up the new battery in my 07 recon 250 in a hurry in the dark and hooked it up backwards. I fried the piece that goes in the battery cable with the 2 wire plug that comes out the bottom and each end of the possitive cable hook on a seperate post on the top. I need to know what it's called and where to buy it. Thanks!

 

Good news, we have your answer on the ATV Connection homepage and there's a good chance the fix may only cost you some pocket change:
