Just wondering if anyone can offer a plausible explaination for why i might get the following IR results for a lighting circuot: L-E 6Mohms : L-E 300Mohms : L-N 300Mohms . I cant understand what the relationship between E-N has the effect of reducing the resistance that L doesn,t. Someone mentioned to me that it could be damp conditions but this does not pan out as it does not have this affect when tested with the L. Perflexed !!!!!! Any brain boxes out there got a better explaination ?
