Default CDI Alternator stops charging on above 1800 RPM

Hi,
My Mercedes W210 CDI (oil cooled) Alternator stops charging on above 1800 RPM.
All internal and external lights become dimmed.

While Idling, there is no extra sound but on increasing RPM strange swirling sound comes on.
Belt already checked.

No Battery light appears on Dash (when not charging) but multimeter shows 10.11 to 11.8 volts
What could be the possibilities?
