    Is there any way that you can have the out put checked with the alternator on the car to see what it actually is putting out while on the car?
    Underdrive pulleys?
    Screwed gauge?

    Get a multi-meter and check what your battery is "getting" while the car is running ...

    Check this site:

    or

    Stock alternator or a 3G? The stockers have the external voltage regulator so that could be an issue. If not the site Mustang_68_Coup gave seems to have it covered (thanks for the link as well!)
