The last time I had this problem was in a non-computerized car. I fried two voltage regulators before I realized there was a shorted diode in the alternator. I knew my voltage regulator was gone when the brightness of the dash lights would change with engine rpms! I don't know if you would get any warning signs in a modern car. Even our built-in voltmeter in the Camaro is a computer display.
From what I have read, computer modules are less tolerant of AC. Low voltage AC can result in "noise" which just confuses things. Higher voltage can damage modules.
