Ok, it started yesterday. I pulled up at the school parking lot and my radio cut off, I looked down and my gauge was at the 8. I got parked, and revved it till it was to normal then cut it off. It didnt start when I got back so I had to get it jumpped.

Just now I was in the drive thru, and as sson as I pulled up, I could tell something wasnt right. I had to keep it revved up some to keep the voltometer on the O. I had my lights, radio, and A/C off. I get to the window and have to keep it at like 3000. Then I leave and hear something scraping under my car. I stop and look to see, and there is a huge plastic cup burning on my exhaust. Well when I got out to see what was making the noise, my car died and wouldnt start.

I got it jumpped and couldnt let it idle for long the whole way home, and it sounded like I can hear a whine from under the hood.
That makes me thing alternator.
 
If you remove the serp belt and spin the pulleys, you might hear or feel something.

Otherwise, I'd get a bench test on your alt. It sounds like it took a crap on you.

Good luck Eric.
 
if its screaming, its probably a bad regulator inside the alternator... thats what happened to my first alternator... it was screaming, all the dash lights and headlights would get REALLY REALLY bright, usually at WOT or after a certain RPM on the street...

the last alternator i had, i had to keep it in neutral, leave it revving and then throw it in drive just to make it home..

so yeah, sounds like a bad regulator
 
Got it all done. I went to two testers and they both said it passed. But I mean if you spun it you could feel and hear **** going wrong on it. One of these machines was the same one who told me that three brand new starters were bad, and they were both the same type of machine. So I went somewhere else where they had an older, but better machine. Instead of just telling you PASSED or FAILED, it would actually let you see wtf was going on.

Turns out it was only putting out 10V.


I love not having to constantly worry about charging problems. :)
 
Eric, I've had to do the same BS with alts lately. One place will pass it even though I know the POS is toast. Go elsewhere and get a good machine and old timer doing the test (they prefer to test stuff than look for parts for retards at the counter) and it fails.

Also in situations like this, I've been reading 11 volts and had a dynamic test done. They say it passes. :rolleyes:

Nice work getting it all sorted. out.
