According to my Bentley manual wiring diagram, on an '04 325i, the alternator ties to the heavy lead on the starter, so if you have battery-to-starter connection to crank the starter, you should have alternator-to-battery connection.
Is the heavy lug on the back of the alternator 'hot' (12 V)? If not, then there is a bad connection between there and the starter. Many vehicles have a fusible link beween the alternator and the rest of the system, but I don't see one on this diagram, just the big main fusible link next to the battery. |

I have had batteries drive me crazy on my 93. I have had to replace them way before I should have to. Then I have had some last 5 or 6 years.
Did you have them do a load test on the battery? They do it for free.
