Can anyone tell about a winding noise from engine at 1st i thought alternator but i don't think it's that hard to describe noise, kinda like when you get that noise from your speakers cause of a bad ground the more you rev the higher the pitching noise. Thanks ahead for you help

Maybe it's a bad ground then. Or possibly a belt tensioner

I have this noise and its the alternator bearing... I have to change it, but I have no time to do it.

It can also be the ac compressor clutch bearing. It is easy to remove the belt to test that theory if the noise returns.
