Hi,
Can anyone help me locate a lighting cable? It's an end-of-terrace
house, built in 1900. It was rewired in the 1980s. I'm trying to find
the wire that connects the ground floor lighting circuit to the first
floor lighting circuit. Can anyone suggest where it is likely to be?

Here is a plan of the first floor (the floor where the up-wire must be
located, somewhere in one of the walls):

It is probably in the most logical place, but I'd like your opinions
on where that would be. Unfortunately, the loft has been boarded over,
so it's not quite as simple as looking ion the loft for wires coming
up from below.

If it proves hard to locate, would an electronic cable-locator (cheap,
hand-held type) be of any use for locating it? Is the wire likely to
be in a chasing/conduit going downwards from one of the 1st floor
light switches? The dual-gang switch on the landing may possibly have
such a chasing for the wires that link that switch to the
corresponding switch in the hall below.

Thank you very much for any help....
