My Patrol GU 3.0 diesel alternator packed in and I took it to the auto electrician for checking. I was informed that the alternator was to be replaced. Costed me $450. When I picked it up, there was no nameplate on the alternator so I asked the supplier what brand it was. It was a name I never heard of, but it has a 12 month warranty.
It is very noisy at low rpm's, but goes quieter at higher revs. Maybe it is just the pitch of the noise that change. It concerns me.
Does anyone have any experience with these ebay-type alternators?
