A1534 820-00045 no power

Hi,
I didn't read CC1/2 voltages, but I get 0V at F4700, and have tried 2 different chargers and cable connectors.

E85_CC1= 0V
E85_CC2 = 0.166V

Do you think that can be something shorted on a J4700 line? Do you have the resistance to ground of those pins on J4700?

Revert cable connection and check again.
CC1/2 lines change their function.

Hi,
With reverse conection, I get reverse values:

CC1 = 0.186V
CC2 = 0V

You need to compare readings with known good board...
