    Strange things in the post. Possible hoax or con?

    As the title suggests, we've had a number of letters to an individual addressed to our home, but who doesn't live here... and has never lived here. We've owned the house since it was built. Normally we send the letters back into the post with "not known at this address" written on it... but...

    Electric knife: strange wiring: request advice

    The knife is Russell-Hobbs, ECO1255, model 13892. I work for a charity which receives (among other things) electrical goods which must be tested before we can give them to recipients. The PAT meter gave weird results: normally when the device being tested is switched off the meter says "lo...

    Strange problem with PIR/motion sensor switch

    Hi, I have an odd problem with a motion sensor switch in a bathroom. The sensor detects motion and switches the light on, but then doesn't switch the light off. However, when I switch the fuse off and then on again at the fusebox, it resets the motion sensor, which works fine, but only once -...

    Strange wire colours

    i want to attach a new light to the ceiling but the wires are old. There is a red wire, a brown wire and what seems like a black one. I dared not get them mixed up as I don't want to blow anything up. Can anyone advise on how to proceed and figure out which wire is which? Thanks

    air bag light comes on at strange times

    My niece has a 2004 Mazda Tribute with a strange air bag light problem. She can make a 40 mile round trip without the light coming on if there are no high load devices on, but if she turns on the heater or lights the air bag light comes on a few seconds later. To me this means the problem is due...

    I have an odd situation in that I get random earth leakage trips which happen occasionally when I turn off an outside light. I have a standard split board, half earth leakage protected, half not. Trips happen maybe once every 50 times that outside light is switched off, never when it is...

    Strange voltage readings - broken earth

    Was fixing a broken twin florescent fitting today and came across something I couldn't work out. First thing I did was measure the incoming voltage. At the fitting I measured L-E =190, N-E = 90v. Scratched my head for a minute until I realized the Earth's coming in from the numerous (4) twin...
