So, those of you have have found a voltage regulator beginning to fail, around what mileage was that?

Thanks.
The voltage regulator last forever if not abused (i.e. shorted, reverse polarity), however, the brushes that is soldered to the regulator wears with use. Worn brushes can be replaced and the regulator should be good as new.
