Hi, new here . so this is my problem. I have 2 switched lights and a switched plug, 1- live plug and a direct ceiling fan on 1 circuit all has been working well since I bought the house 3 yrs. ago. then for no apparent reason they just stopped ! no breaker pop or sparks or anything , I check switches with volt meter and found something strange. no power from white or black BUT if I connect to copper ground I have power running to black and white? I disconnected the fan which ran from power supply at switch's ( thinking that may be the problem since it's the only thing that vibrates and maybe something came loose? nope. still the same ,asked a few people and they said ether junction box or switches ,nope check out ok ! so does anyone have any ideas ? tnx p.s, house is 50 yrs. old but wiring has been upgraded 10 yrs. ago.
