Default Battery draining

If I don't drive the TT for more than 3-4 days the battery dies. Checking battery voltage when the car is running leads me to believe the alternator is working. I just bought a new battery so it is not a battery problem.

Anybody got any ideas on how to troubleshoot this problem?

Default An Ammeter in-line with the various power taps can help to isolate the drain....

It may have been just a bad battery, a cell gone bad.
That was my problem.
Alternator was Ok, but dealer had the car overnite, and it went bad.
Dealer said it was a bad cell, even though the battery seemd OK.
