This sounds like the alternator has failed internally and needs to be replaced.
Most likely the pop was the 175 amp fuse for the alternator. Check the fuse.
1. Disconnect the battery negative terminal first, then the positive terminal.
2. Disconnect the alternator connector, and remove the cable from alternator "B" terminal.
3. Remove the drive belt.
4. Pull out the through bolt and then remove the alternator (A).
