The starter might be weak, but will not drain the battery. Somewhere you have a short or something that is drawing amperage. Even though the alternator is fine, there could be a problem elsewhere in the starting system. I believe the voltage regulator is in the alternator in that car, so it would come up in a test. However, if it is seperate, it could be an issue.
Check for bad wires or grounds and perform the following test with a multi-meter;
Disconnect the bettery and put the tester on the amperage test setting
see if there is a draw with the car and all accessories off, if there is then there might be an issue.
