if you have a schematic that should help you. if not ,normally in 120v black is hot or + and white is neutral or -. hope this helps.

There is no positive or negative in alternateing current ( ac). This is because the polarity reverses 60 times a second in 60 hertz systems and 50 times in 50 hertz systems. Black is usually the 120 volt input lead and the white is usually the common or neutral lead.
