Remove positive battery terminal and car dies?
Yes it does. The alternator will only produce voltage if it has a battery supply. The battery power is used to create a magnetic field in the alternator. Spinning the magnetic field induces an electric field in the stator windings. Then the alternator can produce power to recharge the battery and maintain the electrical supply to the engine and ancilliary circuits.Take away the battery, no electrics, engine dies. Plus, it can also cause an electrical spike that could damage the computer.
