What normally you have to look for is that your belt is running properly because your car might be running a lot more off the battery and not so much of f the alternator, but normally if the alternators bad it will drain the battery even if the cars not running.. Yes your first thing you would want to do is check the wiring and al that just because thats cheap and easy but most likley you wanna get the altenator tested...you can get that done at advance auto.. please rate me if you get a chance and if you have any other questions just let me know ill check up on your problem..

If you disconnect the negative battery cable and connect a 12V test light between the battery negative post and the negative battery cable terminal the light will burn if there's a draw. Make sure all electrical consumers are off and all doors closed when doing this draw test. If the light is on start pulling 1 fuse at a time until the light goes out, when it goes out that's the circuit that has the draw. Trace it from there.

something draining the battery .check blower motor sometimes keeps running even when indicating it is off .remove battery terminal and tap against the terminal to see if there any large sparks.if they are . remove fuses one by one as u test till the spark is not there .find out what links are used on that link and disconect one by one when the fuse is on and test if the large spark is still there
