2002 tahoe battery starting problem

Hello all,
For some reason my 2002 tahoe battery is getting drained after about 4 days of non use. Something is draining the battery. I had just replaced the battery thinking the problem could be that. Anyone have any clues to what the problem could be? Thanks

Welcome to the forum,
start by check all interior lights including vanity mirror lights, ensure nothing is plugged in to any aux outlets i.e. phone charger, USB adapters, Ipod...
Check the battery cables for corrosion or loose wire strands....
If need be pull fuses in a methodical way 1 or 2 at a time over night to isolate various systems that could be causing the run down....

In2pro,
Thanks for the reply! I will check out your reccomendations. I was told by someone that it could be the voltage regulator. What do you think?

Welcome to the forum.

Disconnect the connections to the alternator per in2pro's suggestion. Also can lift the battery cable and insert an ammeter in series w/ the cable and the battery and monitor the current as you remove each fuse.
