Question About Problem With 00ls

[MCTIM_00LS]

I Have A 00 V6 Manual Ls. Friday Night I Left A Light On And Drained My Battery Down And The Car Went Dead On Me On Saterday(drove It All Day And Did Not Charge). I Took The Battery Out And Charge It Saterday Night And Sunday. I Got The Battery Checked Out Sunday And It Is Good. When I Put The Battery Back In I Had 14v Reading Like The Alternator Was Charging But When I Got Home The Voltage Dropped To 12v Which Looks Like The Altenator Is Not Charging. Also When The Car Is Off I Have A Small Constant Drainage Through The P-j/b(#25) Fuse In The Trunk. I Am Wuondering If This Problem Is The Alternator Or Something Dealing With This Constant Drainage Through Fuse P-j/b. Any Help Is Very Appriciated With This Problem.

Not to be rude but... not every word needs to be capitalized.

I know AutoZone and the like will test alternators, but do that have to be removed from the vehicle?
