The infamous alternator whine is that heard all the time or when you turn off the car? When Turn off my Car I hear a whine fade out, it doesnt sounds like a vacuum leak, but now recently I hear it a bit when my RPMs drop pretty low (400).


I want to think it might be clutch/tranny related, because I'm going to order a 5th gen tranny and clutch next week, is this possibly a tranny problem? or alternator problem?


also that alternator test thing is take off the neg connection while the car is running? if it does alternator is bad?



Thanks

 

bump . . .

 

i'm not sure if i have the same problem but my car makes whining sounds when im accelerating and occasionally when my engine is idle. also, my engine has been idling at 900rpm ever since i got my o2 sensors changed at a mechanic. before that, it was idling a bit below 500rpm. anyone have any suggestions on what may be wrong?

 

You should go get the amps and volts read.

 

I had the whining noise recently and it turned out to be dead alternator.

 

if u have a sound system and amp with no capacitor that might be the problem
