"Can only agree that its the alternator."

It could be a slipping belt, when an electrical load switches on. Is it likely to happen when turning on the headlights?

My experience with worn alternator bearings is that you will notice shaft wobble with the belt removed, even if you don't hear bearing noise when spinning it. BEWARE of misinterpreting commutator brush noise or squeaking as coming from the bearing.
