(As per the Fail-safe section in the FSM)

Have you measured the voltage of the battery with the car at idle? Typical voltage is high 13 to 14 volts
If it is overcharging, it can only be the alternator.

Yes, i did. So with the big 3 without the original negative cable terminal it was giving me 14.3v (0g pos alternator to battery, 0g chassis to engine, 0g battery terminal to chassis). Then i removed the 0g grounds and replaced them with the ground braided strap and the original battery terminal with the sensor putting out 13.2 to 13.5v.
