Hi all, looking for some advice for a rookie please. This concerns a 2-way lighting circuit, that's to have some LED downlights to replace old halogens. It was just to be a replacement of lights so a ran a quick Zs test beforehand and MFT sounded "voltage/ polarity" alarm. From the supply side I'm getting L-N 240v but L-E and N-E at 12.3v. So Earth/ cpc has a very high potential. No voltage on it itself with the voltage tester.
There's some very poor wiring in the property so I'm looking for some advice please on where to look and test to find the issue.
Many thanks
