Maybe time for new brushes / regulator.....

Beware of non BOSCH or HELLA branded regulators ! .

You can solder in new brushes for $5 or so if you care.....

Get a spare regulator / brush holder from any of myriad German / Swedish junkers and carry a spare in the trunk ~ takes a few minutes to change with the passenger side wheels up on a curbstone...
