Yikes. The voltage regulator in my alternator went bad but in that case it was undercharging not going turbo. Hopefully these incidents haven't damaged anything in the cars electrics.

At first i was going to suggest using an oscilloscope to monitor the control signal from the ECM to the voltage regulator in the alternator and see if you could catch it acting up but i guess you solved it with finding the broken wire.
