I don't have quick access to the diagrams right now but have you checked your fuses. Common thing to pop a fuse when removing that nut if you didn't disconnect the battery first. Then another fuse for the input to the alternator.

The saturn needs one wire to run. To test- take jumer wire from battery pos post to alternator f terminal. If starts charging you got pigtail wiring/fuse to pigtail problems. To check if the big fuse is blown- check alt output directly at the alternator. One probe to alt case (ground), other probe to alt b (output fat cable) terminal. If charging there, then big fuse blown.

Or, *in rare and extremely odd cases*, check to make sure you have securely fastened the alt to engine block. AND tension the belt so it can actually spin the alt at idle. Then make sure the battery neg post has a (4 gauge or better) cable attached that actually goes to somewhere useful, like the transmission bell housing to starter bolt, for instance.
