why would an electrical socket have low power?
we have a double socket that is branched off another (working) double socket and it doesn't work. I put a volt finder tester on it today and it lit up so there must be some power. then I got a lamp and plugged it in but it didn't come on despite the tester saying there was power in the cable. the lamp works elsewhere.
we got the electrics updated about 6 years ago but I'm not sure these sockets have ever worked. they're not in a very convenient location so I've ignored it but now I've realised that it's probably the only place that the kids wouldn't hear a turbo trainer from their bedroom.
is it likely to be something as dumb as loose connections in one of the sockets?
