You aren't the first one to do this, but it will take some digging to find the previous post with the full data dump on what the fix was. I think it ended up being the fusible link in the underhood fuse box. When you remove the cover you will see a clear plastic window with some thick bars in it. On the left is an exposed nut. IIRC, one of the fuses in there, pretty large - like 175 amps, is for the alternator. That might have been blown, along with others. Exactly how you get in there to check and change it, I don't remember.
