yup, definitely the brushes, and given the ease of replacement, do it yourself. Takes 15 minutes on a 9000, half that on a 900 to replace the regulator and brushes unit. While you're in there, give the grounding pins a cleaning - I've had similar problems resulting from a poor connection inside the alternator. A scuffing with sandpaper helps. Remove the v-reg and look inside: you'll see what I mean. -chris Grunff wrote: > > Simo Melenius wrote: > > > I'm a car novice but my first guess would be the brushes.
