I'm no electrician, so, if there's no easy answer to this, I'm calling
a pro. I'm trying to fix an electrical outlet in my house. Seems like
a wiring problem, though I initially suspected the outlet.

Measured voltages:
Black (hot) vs. ground = 120VAC
White (neutral) vs. ground = 0VAC
(so far, so good, eh?)
Black vs. white = 0VAC
(should be 120VAC, right?)

Any idea what would cause this other than wiring problem? All other
devices on this circuit work.

Thanks.
