A2289 820-02020-A water demage

[macfix_hh_25]

Hello everybody,
I have a MacBook Pro A2289 in the shop. It came in with light water demage, no power 5.209V - 5.213V / 0.014A. Corrotion was found around C7055 (PPBAT_G3H_CHRG_REG).
Disconnceting the battery solves the problem. MacBook starts normally and boots to login.

We cleanded the area and replaced C7055 and C7054, as they were badly corroded.
With connceted battery, its still the same. No power and voltage by 5.213V / 0.014A

C7051 = 12.62V (Pin1)
F7000= 12.62V (Pin 1+2)

Does that mean the battery is the problem or do we miss on something here?

Thank you for your feedback.
Tim

What is the exact 820-xxxx code of your board?
02020 is A2338 M1, not Intel A2289.

If you have 01987 board, check resistance (ohm scale) over C7020.
