[DML] Alternator Sound

["valleyrat12" <valleyrat12@xxxxxxxxx>]

Gee I'm posting here a lot...

OK, I noticed while my car is idling right after it is started that 
my battery voltage is low, below the 14 or so volts it should read 
when running. If I rev the engine the meter will suddenly bounce up 
to where it should be and continue even when the engine runs back 
down to idle, indicating that the alternator is working. Also, a 
whirring sound can be heard from the alternator AFTER the gauge 
indicates that it is working. I have cleaned all of the contacts and 
the condition persists. 

I have noticed this on other cars and assume that the sound is 
normal, but I assume that my alternator is dieing. What would cause 
the alternator to work only after the engine is revved up to 3000 
rpm? Also, there are some wires (2) that are hanging down by the 
alternator that are not hooked up, Black/Green I think.
