What grounded surfaces are there near the screwshell?
If you find the splices, you have probably found the bad connection. The
way I read your post you want to make the K&T circuit a 'proper' 3-way.
circuit could also be rewired with Romex as several have suggested.
Life is a series of trade-offs.
I am really just beating a dead horse now. The suggestion to replace
it is, of course, the best solution.
From what I have read in the last couple of days, you can repair an
existing K&T circuit if it met the code requirements at the time. So
if BETA had a "proper" 3-way switching arrangement and a broken hot
wire, the way I see it, he could just butt splice a new piece of wire
in it's place. You can still use K&T to repair K&T.
I don't think the switching arrangement we are assuming BETA has was
ever code compliant so it would not be legal to repair it.
One other thing BETA should consider is that the neutral wire could
still be in use. And splicing a neutral together that is still in use
can cause dancing. :)
Problems are likely to be at soldered joints. I have seen 2 failed
solder joints (one in K&T) - both were "cold joints" - defective when made.
I have seen the Carter circuit a couple of times and it seems to come up
occasionally on this newsgroup. I suspect it was once compliant, but I
don't know. Wiring practice has changed a lot. No one has ever said
definitively it was or wasn't once compliant. Anyone know any really old
The other question, I suppose, is whether the NEC was adopted in a
jurisdiction when a house was built. It was common for jurisdictions to
have their own codes. I looked up an article in an IEEE newsletter that
said heavy pressure to adopt the NEC (and one of the major building
codes) came in the 1960s.
But the 1920 date for the NEC should be an early landmark. Thanks.
Thanks Terry and everyone else for all of your suggestions and the time and
energy you put into trying to help me get this fixed.
I finally decided to give up. I took up 2 more boards in the attic floor
and got better access to the wiring to the hallway light from above. Then I
used the inductance tester to see if I could find any "hot" wires. Neither
wire going to the hallway light was hot, and I traced both back as far as I
could and got the same thing. Those wires and all 6 wires to the two 3-way
switches all showed no power.
i would get really interested in your wiring, since you dont know what
failed there might be more and the next failure could start a fire.,
in my job i see wiring burn up all the time.
12 and 14 gauge wire burned up carrying 15 amps. they are connected to
might be a good idea to get a electrician to look at
house fires are nasty,,,,,
it would be sad to have a fire, open walls and find the same failure
that caused the fire had caused this outage.,,,,
