Is the voltage regulator part of the alt? How many volts is it putting out?

Could be the computer controlled of the alternator field generation circuit

Offcourse a chip ! I look at the voltage level for both of this alternator wires, blu/whi and gr/whi in a good operating system and it showed.650mv while the alt output was at 14.0v in my car I read 2.4v in the gr/whi and 0.00 out in my whi/blue.
I will check the wiring to the module in the gr and to the instrument cluster charge warning lite for the whi/blue otherwise I will replace the controler board
