theres also a supressor on the back of the altenator both can give you the whine
sterio whines
yesterday evening, my manta begins to make a funny noise, only lasted a few seconds so i blamed it on the transmission, like i always do
.....but later on last night coming home, it came, and did not go away. shut the sterio off to hear it better, and to my surprise, my speakers were whining, with the sterio OFF!!! its a 200W pioneer deck less than a year old, 500 watt jensen amp with 2 10" jensen subs and some nice little jensens in the rear deck. the whine was in tune with RPM of the engine, and i ended up unplugging my sterio from the fuse block to get the noise to stop. the origional AM radio did this in my GT, and heard that sometimes the condensor on the dizzy can do this? i have the pertronix unit so i can pretty much rule that scenario out, but what would make it start this?

cool beans baz, i'll do my best to work up some ambition to check that today, but for now its off to work
A few years ago my Suburban suddenly did that. It started as a little whine whose pitch went up with RPM. It is a diesel engine, so rule out ignition...
Within a week the whine was so annoying you could not use the stereo. I thought the stereo was going T's up. I hotwired the blue wire signalling the amp to come on, left the player off, and the noise was there. So it was the amp, not the player, right? Well guess what. Next week the car didn't want to start, this is the dual battery system, by jumping it off my pickup it started but the volt gauge wouldn't come up to 13 after starting. Batteries would trickle charge overnight and the car would start okay, but the volt gauge would keep dropping as you drove with lights, heater, etc. on. My wife wasn't real happy, this was her "Mom-Mobile" and it has to take kids to and from school every day, etc...
What's this got to do with stereo whine?
The alternator on the Burb happened to be the same as the one on my big work truck, so I swapped 'em. The stereo quit whining and the voltage stayed up, the car was fixed.
The alternator had failed, before going out completely it warned me by making the stereo whine. It only makes sense if you think about it! Ever notice your stereo has a funny buzz when you play it while a battery charger is hooked up to the battery? There is an "unclean" voltage going in, stereos don't like that!
Try disconnecting your alternator wires and see if your stereo quits whining. Then try it with the belt off but the wires on. I'd be interested to hear what you find.
This is my hunch, since it started happening after everything was just fine before and no changes were made.

Hey Smurf- are you sure that the whine isn't part of the music your listening to? They are putting some mighty stange things on some of your generations music these days.. Try putting on some Bethoven or Harry Connic Jr. and see if the whine is still there.
i'm going to check the alternator, i put the sterio in this spring and nothing has changed. i'll unplug the alternator and run it with no belt for future references. i turned they key on, car off and it doesnt whine, only when engine is running.
Tom: i dont listen to my generations music much, i prefer kansas, boston, led zepelin, foreigner. clapton and sieger are pretty good guys too.
i tell ya, i was born in the wrong time, shoulda been born 30 years ago.

I guess you wouldn't want to hear about the concerts I've been to, but I digress, and we are moving way off topic. But needless to say they were good. Jarrell
lol, the trick is to try and get me to act my own age, let alone like i was born 30 years ago!!! i seriousely have the mentality of a 2 year old sometimes, i swear ......but i almost forgot one of my favorites, tom petty!
to keep us on topic:
i had to run to town real fast earlier, and the sterio stopped making the noise before i got to do anything to it, so when it does it again, which i'm positive it will, then i'll go throught he process of elimination and see what truely is causing it.

it did it this morning, the little black box was loose on the alternator so i tightened it, good on the way to and from school today atleast. i think the pressureplate whent kablooey so no more opels for rest of the year
back to the S10, opel is still up for grabs, maybe i'll post a "bump" in the "manta for sale" thread.

Born to soon?
Yes, Jared, but if you were born 30 years sooner, you would be old...like me
