A whineing noise has developed from the direction of where the alternator is and some bloke who has built a few engines in his time said it sounded as if the alternoters bushes were wearing out and that eventually when they come off completely i would then see the red light come on the dash!

Does his thery sound right as it is definately not the belt sliping and the noise is starting to iritate even though its not loud, you can hear it as you drive along.
