I have 4 lights in the hallway, all controlled by the same light switch. One of the lights has never worked since I moved in.
I removed the light fitting and tested the wires with a volt meter. If the light switch is off I get approx 0 reading.
With the light switch on, if I test the live wire alone I get 22V. If I test live and earth I get 33V and if I test live and neutral I get 46V. Any ideas what this means? A loose wire somewhere?
There are a lot of 12V lights around the house and half a dozen transformers in the loft but if I test the faulty wire with the meter on DC I get 0 ready so I don't think it's connected to one of the transformers.
I've traced all the other light fittings back to a junction box in the loft but cannot find any route to the dodgy cable so I'm not able to disconnect it.
