I was working on my whip light, when it went out. I also notice my winch was not working. Looked in the manual and online. I couldn't find any listing for a winch fuse. I had checked the fuses earlier, and I thought they were all good, my mistake. This time I pulled each fuse and meter it. I found the backup fuse(15 amp) was blown. Replaced and all is good. I had an old instructor who said always double check fuses . You can't trust them.
