Your issue could be with a piece of fusable link that is located behind the battery. Sometimes this can blow causing the same symptoms of a bad altenator. I would check here first before doing to much more troubleshooting.
Have you checked the fuses? If OK, possible bad fusable link. The fusable link is a piece of wire that acts as a fuse in between the battery and fuse box. In other words, make sure you're getting power to all the fuses in your fuse box. Useing a test light, turn key on and see if the etst light "lights up" at every fuse. If you get no power at the fuse box, most likely a bad fusable link. Why would a fusable link burn out: Look for anything added on to the car like, stereo systems, etc. Sometimes these can over draw the wiring and blow a link. Hope that helps.
