Ok, fresh thought after lots of reading. Workign one problem at a time.
Alternator first, since it failed first. Found a reference to the Battery light situation that Ray provided someone.

The light going out after starting should indicate some form of current increase from the Alt.(makes sense) I had checked for voltage at the Alt. side of the Mega-Fuse but I used my test light. So, I have no idea if it may actually be charging. I plan to test the actual voltage on both sides tonight if the weather holds.

The car, with battery down, now has airbag light flashing - Tach on 0 while running, Speedo freaking out. So, maybe the computer also cannot handle the voltage drops or got damaged while running with no charge.

Still cannot pull any codes.
