Carrying out an EICR.
Turned all lights on and went to the DB to isolate before checking R2 using R1+R2, linked at the DB and testing at all pionts.
First point; 200+MOhms, second; the same. Randomly test another five points, all +200MOhms.
Marked down the fault, no CPC continuity on lighting circuit before noticing the light switch was off?
Checked all the others and they're all off, the old geezer had followed me round turning the lights off.
