    I am often called upon to help people with, for example, a vacuum cleaner which no longer works. First thing I do, I check continuity of the live and neutral wires between the plug and the machine. Most of the problems are just of a continuity nature along the 10-20 foot cable, but where? , Not always at the ends. Just cutting in the middle, and checking both ends for continuity, is pretty destructive. Until now, I use a pin to pierce the wire covering and measure for continuity, and test the continuity until I find its location, therefore not having to cut the cable unnecessarily. Works fine, but I don't like the fact that there are now a number of tiny holes in the wire covering. Is there any better method? I tried using a compass to see if there is only a swing in the live portion of the wire, butdoesn' seem to work.

    Thanks, sounds great. If the continuity is broken in the neutral, I'll just swop live/neutral, and test with the' gadget you mention.
