    Ah, wait...

     

    OK here is the Blind-Mate voltages

            Ok here is the Blind-Mate connector updated

     

    Pin one is in the upper lefthand corner with the polarization tab on the top.

     

    PIN               mac off                       mac on

    1                  12v                            17.5v

    2                  -0.14v                        GND

    3                  7.3v                           12v

    4                  -0.14v                        GND

    5                  7.3v                           12v

    6                  -0.14v                        GND

    7                  0v                             12v

    8                  GND                           GND

    9                  13.9v                         4.92v

    10                Chassis GND                Chassis GND

    11                5.0v                           0.72v

    12                Chassis GND                Chassis GND

    13                0v                             0.04v

    14                Chassis GND                Chassis GND

    15                0v                             10.8v

    16                -0.14v                       GND

    17                0v                             10.8v

    18                -0.14v                       GND

    19                11v                           18.13v

    20                -0.14v                       GND

     

    *there seems to be 2 different grounds at work here Common Ground and Chassis Ground.

     

    ** I am beating myself silly for not checking the connector with the mac off while the crt was removed....this may throw off all the off state readings.
