OK, there is a "leak" in the system.
You need to disconnect the negative battery cable and install an ammeter in series between the cable and the battery post. Close all doors and see what the ammeter reads. It must be below 100 milliamps (preferably less than 60 milliamps). It probably will be higher than this amount. Start pulling fuses, one at a time, until the meter drops down.
If it never drops down, even with all fuses removed (a definite possibility), then remove all the wiring from the back of the alternator. If the meter now drops down to zero, the problem is a current leak internal to the alternator.
