It looks like it feeds most of the outlets in the LR, DR, and probibly the ceiling lights, and the upstairs BRs.
I figure I can fish new wire up through the basement for the outlets on the first floor, and I can feed down through the walls from the walk-up attic for the second floor. My PROBLEM is the three ceiling fixtures (on wall switches) on the first floor.
How does one replace the wiring in these? I was thinking about tying a string to the old wire when I pull it out, and using that string to fish new wires. HOWEVER, I do not know if they used the "tubes and knobs" in the walls and in the ceilings...the ceramic tubes would make this very difficult. Will I have clearance to pull the new wire through?
