    I think that I know what you did, and what you are asking, but I'm not totally sure.
    Would you mind adding some punctuation so your post is easier to read?
    I don't want to try giving you answers until I'm totally sure what the situation is.

    you replaced battery
    replaced voltage regulator
    replaced ignitor
    replaced stator
    replaced alt brushes

    did you replace stator?? or just the brushes?

    you need to clean the 2 copper rings that the brushes ride on . did you replace brushes as an assembly? springs may be week.

    read this thread first few paragraphs ELECTRICAL SYSTEM OVERVIEW: then skip down to this heading DOUBLE BONUS ROUND!! Charging System Electrical Specifications:

    The Ultimate Relay, Switch, Sensor, and Diodes Guide

    ohm out your charging system as discribed in the link posted above
    also a new battery can still be a bad battery
