Hi everyone. I have a doubt. If I have to test a ground pin of a 5V connector (suspect bad ground), to do a continuity test is it necessary to touch with the multimeter probe any point of exposed metal of the chassis? Or do I have to touch exactly and directly the negative pole of the battery...
Just started PAT testing and trying to understand why stuff fails. Recently had a large fridge fail. The cable was scuffed with a slice of the flex missing so the yellow wire was visible but not the copper. The readings on the tester were 0.6 plus in various places. Could it just mean the cpc is...

I'm doing testing ahead of a board change. It's a cramped Wylex rewirable installed by Spiderman himself. (I still haven't worked out why there seem to be 4 lives and 5 neutrals for lighting circuits, but that mystery will have to wait until the point of no return)
I eventually got the RFC lives...
