820-02016 no power

[Kyle93]

Arrived with a burnt CD3217 and usbc amp meter going on and off every few seconds. Second port stays on at 5v

Replaced bad CD3217 from a donar M1 board but same issue. What should be checked next?

Replaced with one from donor 02016, same position?

 

[Kyle93]

different m1 board. cd3217 needs to come from only 02016 then?

You may have damaged diodes, or capacitors on the USB-C connectors lines.
Compare readings with good board.
