I need some help identifying a whining noise coming from the front. This started a few months ago. I did a search, but couldn't find any answers.

The noise only happens when it is drawing electrical power like turning on the AC or headlights. If I turn those off, the noise goes away. The whine gets louder as the RPMs increase. I have disconnected all stereo equipment. Radio is off when i hear this noise. Anyone know what might be the problem?

Oh I have a '01 if it helps.

Pop your hood and look above your intake mani for a supercharger, if thats not it, its your alternator or the belt

I see a large sliver football thingie there. Is that a bad thing?



J/K that was pretty funny

So that that mean my alternator is going bad if it is not a loose belt? Do alternators crap out at only 60K?

That was classic!

Is there a way I can check to see if the alternator has crapped out or on the way to crapping out?

test it, and if you dont know how, go to autozone have them test it.

I finally got around to testing my alternator. The results came that that I was pulling around 80 Amps. Is the stock 5th gen 90-100A ish? Also voltage was around 12.5v @ 2000rpms. Normal is 14V?

Seems like it's on the way out? Also i am running the battery in the trunk would this have any effect making the alternator running harder than normal?

I agree firmly with this statement.

You voltage output should be around 14.5 volts, as far as amperage I am not sure. Sounds to me like your alternator needs some butter because that **** is toast.
