I have learned why they have waterproof winches now. I actually needed my winch on the trail for the first time last weekend and it was dead. When I got out of my predicament and back to a part of the trail to take a look at it I found out the issue. The control box had taken in a lot of water and it couldn't get back out, some time ago apparently. Now take into consideration this winch has never been submerged but my wife does like to drive into mud holes pretty fast, to make a splash, lol. It apparently got up under the lid, poor seal and I didn't realize it.
I'm in the process of ordering new solenoids for it to replaced the severely rusted ones in there. At least they aren't very expensive. I also plan to drill a hole in the bottom of the box, I'll put a rubber plug in it and pull it every time it's anywhere near water just to be sure.
This is just a friendly reminder for those of you with winches to check it before you hit the trail just to be sure it will work and to check your control box periodically for water. That is all. Have fun out there!
