So my bilge pump quit and is scheduled to be replaced.
However, I noticed 2 transom (battery switch area) 30 amp fuses. Both were pretty cruddy. I took each fuse out.
Re seated them and then went to turn power on at Master and flipped on Livewell, Nav/Anch, Freshwater switches. I get this buzzing/hum sound. They do not function now. The rocker switch lights work. Even the dock lights dont work now. The only thing that powers are the Courtesy lights and Stereo.
When I removed and reseated the fuses, did I mess something up? How do I clean the corrosion off the waterproof fuse casing and should I replace the fuse itself?
