What type winch do you own? If it's a Warn go to Northern Tool and they have everything there you would need.

When I had the Kodiak my solenoid crapped out also, only because when the Yamaha dealer mounted it they mounted it outside on the rear frame and that's a big NO-NO. The solenoid gets all crapped out with water and mud and it's junk after a few months. When I replaced it I mounted it inside under the seat compartment and I never had a problem after that. Even with the Grizzly and the new type "contactor" I mounted it inside where it's somewhat protected from the elements. I hope this helps.
