The rectifier/regulator is responsible for 3 phases (system ground, 12 VDC to the ignition and fuse box, & 12 VDC to the starter solenoid/mainfuse)

The alternator supplies power (AC) to the coil side of the headlight relay, the rectifier supplies power (DC) to the switch inside the relay via a fuse.
In between the alternator and headlight relay is Diode B. If the diode is bad it can also prevent the headlight relay from turning on the lights.

Just something else to check before getting ass deep into the stator.
