Very high-pitched whine coming from the engine bay. It increases/decreases with RPM and seems to be quieter when the car is warmed up. The sound is louder when the audio head unit is on, which makes me suspect the alternator is the problem. It confuses me that this can be heard with the radio off and outside the car. I looked for examples of noisy alternators and the whine always seems to be much lower.

Curious if anybody has experienced something like this?

Video attempt at catching the sound. I can hear it loud and clear with my headphones but barely audible on my speakers.

Thanks everybody. Definitely the alternator.

The Spyder just started doing the same thing...not sure if I've gone crazy or unlucky.
