The current created in the generator (GEN) stator winding is AC and must be converted to DC before it can be used in the electrical system of the car. The conversion (rectifying) occurs using a DC bridge consisting of six diodes, two diodes per phase windings.

The stator windings generate three phases and are delta connected An exciter diode is connected to each of the three stator windings. The six rectifier diodes are bridge connected. The diodes are pressed into a diode holder.
