Okay.
I'll do that tomorrow morning.
In the meantime, thank you very much for your help.

Pin 1, 12.2V unstable.
Pin 2, 12.2V unstable.

F5200 = 0.2ohms

Diode Pin 1 = 0.487
Diode Pin 2 = 0.490

Tests performed. Same error.
Thanks for your reply.

Dear Team

Perhaps you can help me.
Motherboard 820-02016. MacBook M1.
MacBook removed with water damage to the sound card, completely oxidized.
Sound card replaced, the cable too.
Nothing visible on the thermal imaging camera.
CD3217, big point, replaced, both.
When I plug it into its charger, the multimeter shows:
5.190 Volts, amperage from 0.190 to 0.440 continuous.
Can I, with your help and my little knowledge, save this MacBook?
Thank you for reading.
