Gentlemen:
Both alternators failed on my 83 240 D and 85 300D.and replacing the Voltage Regulator/Brush pack did not solve the problem. I tried and I am still getting a limp 12.1 volts at the battery vice 14,5 expected,

So I am assuming the stator or commutator went bad.
Arent the stator and commutator relatively infinite life components? Does this mean i shoul djust replace th entire alternator? What failed? Both cars are 300K mileage vehicles.

I thought only VoltageReg/Brushes could fail on Alternator? (83 240D/85 300D)
