More than likly that is the cure, the connections at the fuse box. You must remember that, If I remember correctly, your Brick falls into the catagory of faulty wiring. A lot of the 240 in the early 80's had bad wiring insulation that seemed to just crumble and left the wires exposed. Check some of the threads on this board concerning the faulty wires in certain models. Sorry best I can do..I am sure others on the board will come up with some more exact ideas..:)
