My car has started displaying the following symptoms:
1) A high-pitched whine coming from the area of the dashboard (which is really fricking annoying)
2) Last night, while running a fairly high load on the electrical system (headlights, interior lights, heater, and tape player), I noticed the whole thing flickering. The lights would dim a little, the engine sounded like it dipped a little, and the whine lessened for a second. This happened several times.
I have a warranty on it, and I'm going to take it to the dealership. My regular mechanic says it sounds like something's going on with the alternator. That makes sense, right? Could a problem with the alternator be causing that really annoying whine? (The one coming from the car, not the one from me.)
Does the pitch of the whine vary with the engine speed?
What kind of car is it?
It's an '02 Accord, V6. I haven't noticed the whine really varying with the engine speed, and actually, the engine doesn't even have to be on for the whine to happen. It starts as soon as I turn the key the first notch, before the engine starts.
Happy birthday, shrift!
What great news for Kat and Lori! Congratulations on the twins! Two babies, no waiting! All kinds of feeling-good vibes for you, Kat.

It's not coming over the radio speakers, is it?
eta:
It's not related to the heater fan, is it?
Does the radio turn off when you honk the horn?
Just my dad then, huh?
It's not coming over the radio speakers, is it?
Nope.
It's not related to the heater fan, is it?
I don't think so. It persists when everything is turned off -- audio system, heater, etc.

...no.

Congratulations, Kat and lori! More Buffista sprog to spoil. Wheee!

Does it happen when you turn the key to the Accessory position?

Yes.
Googling (and you) seems to suggest that alternator whine should increase when the engine's running at higher speed. I may need to sit in my garage and test it a little.
The other thing googling suggests is that alternator whine can bleed into the sound system, but since the whine isn't actually coming from the speakers, I'm hoping I can eliminate that.
