If the exposure time changes when you spin the thumb wheel you have "Easy Exposure Compensation" set to "On". Leave the command and sub-command dials alone and change the aperture on the lens itself, as you said, "like it was originally intended" .
It may be just too dark to get a proper exposure with any lens depending on the aperture you're choosing. How long were the exposure times (shutter speed) when you were doing this?
