Alternators - MARELLI: Description

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. The 60 amp. alternator models also have three energizing diodes pressed into a support assembly.
