What should an eber fuse look like? Basically I had to change a fuse for the cig lighter yesterday and remembered from a recent conversation on here that the fuse for the eber being on the door post on the drivers side (in a Westy anyway). As we've never used it, i not been bothered by it not working, but always thought it may be the fuse. So i opened the box and "wiggled" it, hey presto we now have a working eber - at least the fan, time/timer work but not really tried the heating. Now I know that essentially a fuse is a piece of wire but I was expecting to see a more "professional" fuse such as

in place, ours is a thick piece of wire is a red plastic housing (very DIY appearance, which may be ok) but it certainly doesn't sit right and looks a bit corroded, what should it look like?
Sorry i can't post a picture at the moment but will later.
