alternator belt burning up
This is puzzling. The battery is good,the alternator checked okay,belt tension okay but when I make a turn or turn on the headlights the alternator belt starts screeching. The volts also drop
down to 12V when the headlights are on. Overload?

I've been having on-going problems with my dual alternator belt. Kept having to replace them cause they were screeching. This time with them going out, the screeching is really bad at night when I have lights and the heater running.
Turns out that my water pump is going out. I found out because I was consistently loosing a little bit a coolant at a time through the weep hole. I have a new water pump waiting to go on.

Well if its not the alternator I would check to see if its the belt. Is the belt worn? Is there any grease or oil on the contact end?
Also are you sure that the turning and the screeching isn't another problem? Do you have power steering? Have you checked that belt if you do?

is there a Spacer on the Long bolt that you Install the alternator On?
where did you PLACE it?..if it is on the FRONT you are Wrong.It needs to go to the Back of the alternator,inbetween the alternator and the bracket.
the front bracket of the Engine must Touch on the Ear of the Front of the alternator..
I am saying this,because I think you have the belts misaligned due to the Spacer not being installed incorrectly.That would cause a Squeal,snapping belts,etc.

the car has all new OEM belts, all properly alligned and clean. S5's have no spacer. It will only screech when there is a load such as headlights on. Even making turns will give off a screech.

The deflection is about 3/4" . There is no problem if all accesories are off,drives fine. With the car parked,at idle ,headlights on it's okay until you rev it past 900 rpm then it starts screeching.
I swapped in my friends alternator and it did the same thing.

just a guess though.
good luck with your mystery.
