Firstly you should never unhook a car battery when running, when re attached this can induce a voltage spike that can destroy delicate electronic equipment such as the main ECU (computer) with that said i feel that the alternator is faulty, get the battery fully charged and start the car and get the alt output voltage tested, start here.
