Alternator - CHRYSLER: Operation

The alternator brushes relay current between slip rings and field coil. A rectifier bridge, connected to stator windings, contains diodes molded into an assembly. This rectifier bridge changes stator AC voltage into DC voltage, which appears at output terminal.

The blocking action of the diodes prevents battery discharge back through alternator. Because of this blocking action, the need for a cut-out relay is eliminated. Alternator field current is supplied through a diode arrangement that is also connected to the stator windings.
