some capacitors make a high pitched whine when they are energizing. a capacitor would also explain why the whine persisted after the car had been turned off. would also explain why the ability to hear it in a certain range of reving the engine as the alternator was spinning up and increasing output. just a theory. mabey somebody can take it somewhere...

i really dont know anything about the car, but i have a little electrical knowledge.
