Still trouble shooting battery saver mode problem ( when battery has full charge )

On the alternator there is a 2 wire plug. As I understand it , one wire senses voltage and one wire tell alternator to charge or not charge.

With the plug unhooked, and a voltmeter hooked to the disconnected plug contacts, what should I see when:

1. Car is off
2. car on but not started
3. car is on and engine running

Trying to determine if pcm voltage regulator is bad or is plug is bad
