It's possible, I suppose, for a voltage spike to take out things like coils and relays (which have small coils in them).

The VR is used to limit the voltage put out by the alternator. So generally, if the voltage goes too high, the VR is the primary suspect and not the alternator. The whine could possibly be the bearings. Or it could even be something that isn't a problem.

I suggest cleaning up the ground point underneath the relay board, and cleaning the alternator and VR connections on the board as well. That might help... Might not, though.
