Are your black wires in the sub panel going to the neutral bus bar with the grounds and the white wires on the breakers?
I haven't looked that far into yet. It's got to be either backwards upstairs at the subpanel, or in the basement where they tapped off of the main panel. The first thing that I want to do is to install a switched light in that area so I don't need a flashlight. Later today I'm going to look and see how it's wired in the basement. I'll update this thread as I learn more
