belt screech?
#15
My car does the same thing. The aftermarket alternator I went with does not have a clutch pulley, so when you shift rapidly the crank (and thereby belt) speed drop, while the alternator shaft speed remains high. The squealing is the shaft slipping until the friction slows it down. Either find a clutch pulley that will fit your shaft and have it put on, or replace the alternator with one with a clutch. Or leave it as is and deal with it. It isn't gonna hurt anything. My belt's got about 50K on it doing that since the Alternator install. Doesn't so much as squeek otherwise.

I had recurring cold start squeaking issues. Tried everything, new idlers, thumprrr tensionser, etc. The only thing that seemed to work was going to a Gatorback Belt. Has not squeaked in over a year.
(BTW, its an auto, so no alt clutch)

So I have subs in my s197 and they roasted the alternator. I bought a bigger one off am (can't remember the amps) and installed it. Now when I'm wide open and it shifts it sounds like a belt slips or screeches for a split second. Any ideas on what that could be or how to fix it?
like the OEM alternator. Did you go with a www.PAperformance.com
alternator or an off brand from the stereo store?.
The moving mass of the alternator keeps going when the RPMs drop
and your belt is slipping (screeching) because it cannot slow down
the alternator fast enough...
A new serpentine belt will be in your near future.
Better carry a spare belt and the tools needed to replace it when it snaps.
