My car's battery life has been draining really quickly. I had the alternator checked out, and Advanced Auto said it was "like new". The only thing I can think of is maybe the wires or a fuse somewhere or even a ground, but I'm not sure where to look first. Any thoughts would be appreciated!

Oh yeah, it is an EG.

 

Have the battery load tested and if good, then test for parasitic draw. Plenty of info on that in the forums here on HT.

 

Definitely the first thing I would check is for parasitic draw, a basic parasitic draw test can be done with a 12V test light...
