Ford Fiesta - High frequency noise remanufactured alternator - JB0702
Hi,

I have purchased a remanufactured alternator for my fiesta. I just got the alternator and I realised that when I turn the pully, it’s making really high pitch noise. The noise is not loud but I can tell it is definitely there. I asked my dad and he said he can’t hear but my siblings saying that they can hear it.
Is it normal to hear a whiny high pitch noise? It is coming from both directions although anti clock wise is not as loud as clock wise. All parts in the alternator looks intact and good.
I have recorded the noise and here is a link.

I can't open those links. Something fishy about them?

I'd suggest it's new brushes bedding in, but how much did you pay for the alternator, cheapo?

Difficult to tell off the car . I would fit it to the engine and see what its like under load. Its probably makes a different noise in each direction ,as the cooling fan is rotating the opposite way.

Okay I will put it in a car and see how it plays. It makes the same noise when I turn it with my hand but I guess it might be different with actual engine load. Thank you :)

The link opens my YouTube app. Maybe it only works with mobile? I paid about £75 for it, I will install it in a car and see how it goes.
