Alternator or VR issue?

So got back to this during the weekend.. ran new wire for field and jumped from VR ign to new VR FLD and get less than 12 at the alt field and nothing more than 12.3 at alt post even with increasing RPM.
Not sure why your quoting my post there. Seems your following post 2.
My suggestions, based on the melted link, were in post 15. Post 16 was where where to look for background info on how it works.
