    What is the voltage to ground (not diode mode) of PPBUS_G3H @ fuse F7000? Check both sides.

    What is the voltage and current draw of the power adapter of the logic board? Check each USB C connector. Check both sides of the USB C connector.

      It's charging the battery just fine. It doesn't want to power up or complete a revive in apple configurator
