What Astrobuf said. But it's been a week. Is it still an issue?
If you have replaced the alternator (yourself?) you have a clue. You need a cheap voltmeter that also measures current. Many, many helpful youtube videos out there, but this is pretty simple.
1) You are going to need at least one door open. Make sure your dome lights are turned off. You may have the door lights. These will cause current draw.
2) Pull each fuse one at a time. Note when the current drops off. There's your problem.
