I was checking my maxi fuses regarding my radiator fans in this thread, and when i took them out they looked like this:
What is up with that dark corrosion/burnage? Or is that normal corrosion from being outside of the car in the moisture? I've never seen dark corrosion/burnage on anything in an outside fuse box before. I did, of course, clean all the corrosion off and the terminals are nice and shiny again.
I haven't pulled them out of my 2000, but from experience with other cars, it looks normal. They handle a fair amount of current, which heats them up, and discolors them. The corrosion appears to be in places other than the contact area, so that could be from condensation.
