Alternator belt slippage

This has only happened recently. My alternator belt squeals whenever there's extra load put on it like the heater or foglamps, A/C, etc. I notice now that there's a 'chirp' when moving off at low revs coming from the alternator belt as well. Is this common with 3S-GTE's? From what I've felt, the belt is tight... but it flaps around a bit at idle, and I don't know how much is "too much" slack on the belt.  I notice that it happens mostly in the wet as well.
Is there any real fix for this (asides tightening the crap out of the belt)? Can the alternator belt be 'too tight'?
Any advice appreciated.
Cheers.

The belt shouldn't flap around... it should be tight enough to stay straight whilst running.
Silicon spray will often get rid of the squeels and it will preserve the belt.
Worst case scenario change the belt... no "remove intercooler" step required for this repair... just about ten thousand turns of the stupid tensioner bolt!

I usually tighen the belt to the point where you can twist it around 90 degrees, anymore and its too loose, any less and its too tight. Someone showed me that trick and its always worked well for me.

And don't forget, with the tensioner, clockwise loosens it, and anticlockwise tightens it... That gets me every bloody time. 
Also, keep in mind you can't have the belt too tight as u'll be putting excessive load on the bearings in the alternator and aircon pulleys.

Understood. Thanks for that guys.
I'll have a fiddle with it this afternoon and see what becomes of it. Must pick up a bit of silicon spray too, seems like a damn good idea.
