Old wiring and fuse box?

Hello, by "old wiring" I am uming knob and tube systems, so, if the wire does not look like a modern plastic wrapped wire that is probably what you are dealing with. That being said with power with nothing working says that the ground or common line in the group is burned through. There should be three wires a hot a common and a ground, trace the lines and you will find one open, put in a box, splice together, and they should fire up. Good luck and i hope this helps.
