Low IR readings on lighting circuit - 0.654 Mohms

I have had this similar reading before a few times funnily enough. I am pretty sure it is the RCD coil. Make sure the rcd is not included in any part of the test

I have low readings such like before, it's just tracking down the load. What about pir light connected straight onto the supply (i.e. no switch). Favourite is socket wired into the lighting for loft tv booster, or even a shower pump!

Blimey just noticed the date of the original post, surely the 'faults' been found by now.
