The wiring itself was still OK, but the old "pipe" conduit had a lot of poor ground connections, so I got rid of it.
Sheesh, some of the piping was as heavy as water pipe.
Put it all out in the alley and within a few minutes a metal scavenger came and got it.
Started in with the Sawzall about 7 am and later my wife asked me what I was doing. She says she gets scared when she hears me running power tools and does not see what I'm doing.
Told her she'd be a lot more scared if she /did/ see what I was doing.
