Blower Fuse Bypass

I have a 86' 560 SEL and the blower is not working. I have traced it to my blower fuse , and it has melted the bottom seat down into the bottom of the fuse box. Needless to say the fuse can not connect to the bottom terminal. It is my understanding that this is a frequent problem on 80's MB's. Does anyone know the best way to bypass this fuse outside of the fuse box? Also I have a small black box outside the fuse box that has a thin copper plate that is burned in half. DOes this go to the blower also. I would appreciate anyones help with text or diagrams. Thanks.
