    Hey folks,
    Batt light is ON in dash, checked the batt volt(12.7) while off & 14v while running means its receiving charge while running, Wonder why batt light is ON. Any thoughts appreciate.

    Check alternator connections, not toyota specify but generally in my experience that means the alternator internal sensing circuits are bad.
    Replace alternator.

    Check the G2 connector, namely pin 4, and associated wire (gray)
