Our house was added on to by the owners over time, so the wiring looks like it was done by a crazy person. If you look at the map of it things make almost no sense. Basically every electrical thing, including the phone line, looks like a game of chutes & ladders. Repairing anything is a herculean task even for experts. On top of that the attic is so tiny that none of us can fit in it & a lot of wires are in the attic. Because people used to be smaller 100 years ago when the base of the house was built.
