Masraum,

I havnt read all the threads and dont know if anyone has told you.

Your breaker box is segregated into two 120 volt buss bars with a common off to the right side. Each 120 Volt busses have a series of 120v breakers isolating each circuit. Each circuit should have a black (Hot) 120V with a white common and a green ground. The white and green are ultimately connected together at the ground stake below your breaker box. The buss to the right were all your commons are connected should have no voltage between it and the green ground because they are connected in the circuit. You should only get a 120V reading across the black and white/green. The lower voltage is indicative of galvanic corrosion between dissimular metals. Any voltage reading from your white wire indicates a short probably in the box where your light switch is. The switch should open and close the black circuit only. FYI 220V is two 120 volt breakers integrated as one creating utilizing 2 blacks at 120V and a ground (green).

Poke around in the box and untie the connections. check for corrosion and discolored (Hot) conductors. strip the old off and twist tie then back together. (If you have enough service loop) If you run into any problems PM me. later...I was an electrician in my past...

Thanks
