I'm old enough to remember when they weren't made from chrome-plated Mazak, and were actually good screwdrivers OK you mains tester "Hater's".
I purchased one of those sockets testers at Maplins Picture at

It confirmed what i had said in previous posts that all the sockets in the house according to the socket tester are OK except the one in the kitchen and two other sockets in the upstairs bedroom. The socket tester stated "NO EARTH" on the affected sockets. However, the affected sockets do have an earth wire connected to the socket from the main wiring. In fact the affected sockets have also been earthed to the metal back boxes. So my 99p jobby was actually correct in showing a problem. I also forgot to mention that I haved a digital mains tester(a little back screwdriver with a digital display) and that showed voltage on the affected sockets. Therefore, it appears I have wasted £4.49 on a "tool" which only confirmed that I have problem. therefore, I go back to my orginal question of how to I trace the problem in wiring to discover where the fault could be.

Who has total faith in my 99p mains tester.

To know what your problem is exactly, you need to invest a whole lot more than £5.48...

If all the sockets are on the same MCB circuit (or fuse):
Then you have to trace where these rogue ones are connected to the circuit.
If it is a ring then you have TWO breaks in the CPC
If they are on a spur or a radial then you may only have one missing or damaged connection.
You can see if they are on a ring by seeing if there is continuity between the two reds and the two black cores connected to each socket.
Use your skill and judgement to estimate which are the most probable of the existing sockets that they get their supply from. Then examine the terminals for good connections. If you find no probs look for damage to the cables where e.g. a nail has been put through the floor or a hole drilled in the wall. If theer are hidden junction boxes then there may be bad connections that you can't see (this is why you are not supposed to have hidden JBs)
i think the consensus is that people should buy such a tool to find problems rather than sticking screwdrivers and fingers in live circuits -not realy a waste when you weigh up the dangers!interceptor said:

-there even worse (i do have one
) the voltage displayed is so far out its untrue, wrong infomation is worse than no infomation in my book!DIYnot Local
