My GF hall light (on a 2-way switch system)stopped working so I investigated the circuit. There are only 2 supply wires in the ceiling roses downstairs so I was confidently expecting to find junction boxes under the 1st floor somewhere. All the underfloor wiring is old-style single wires in black metal conduit jointed together with tees and elbows - and having had most of the floorboards up and followed the conduit, there is not a junction box in sight anywhere! Surely the connections weren\\\'t made as the conduit was fitted, and they are now inside? Has anybody any experience of seeing this before? House was built in the early 20\\\'s, and I fear I\\\'m looking at a rewire here... Any clues to this most appreciated.
