91 Suburban, under dash lights stay on but the dome lights do not come on.

[ballencd]

Have not moved my Burb in the drive for about 10 days and when I went back to start it the battery was dead....like totally dead. 0VDC with a meter. I pulled it and put on a charger for a few minutes and the charger stopped and displayed "BAD BAT". Next step was replace the battery......for $180! Wow have they gone up. The car starts now and puts out 14.4 VDC while charging but under dash light stays on with all the door shut and the headlight switch turned off....(under dash part of the switch). The dome lights don't come on at all now but did work before this happened. IF I open a door the intensity of the under dash lights brighten some. The dome lights never come on now.
Have looked in the forums and can't find anything related. Anyone know where I should start looking. I would suspect a shorted wire somewhere but why are the dome lights out??? I guess I should start making sure that they are not burned out first making it two issues. Any other ideas?
