NOTE: Some models may be equipped with Bosch alternators.

Marelli alternators are conventional three-phase, self-rectifying type alternators. Six silicone rectifier diodes are connected to form a full-wave, three phase rectifying bridge. The three negative rectifier diodes are pressed directly in the end frame. Three positive diodes are located in a heat sink which is insulated from the end frame.
