The exterior differences to date between the new compact alternators compared to the previous ones are the following:
t  Modified voltage regulator
t  Oval shaped housing with a round joint for the double connector, compared to the polygon shaped double connector which was used until now
t  Modified designation of the connection terminals → Current flow diagrams, Electrical fault finding and Fitting locations
