MacBook Air A2337 - 820-02016

Hello! The MacBook works from the network but the battery does not work! It does not charge the battery! Replacing the battery did not change the situation. Please tell me what could be wrong

Measure the voltage to ground of each pin on the battery connector on the logic board without the battery. Post each measurement.

PPVBAT_AON_CONN=0,884
I2C_SMC_PWR_3V3_SCL=0,459
I2C_SMC_PWR_3V3_SDA=0,458
SYS_DETECT_L=0,489

the indicators are identical to the working board

If the MacBook works from the mains, then we can exclude the CD3217?

These are diode mode measurements but a good start. Not shorted.

Repeat the same test but in dc volts mode of the meter. Be sure that your battery pack(s) are compatible with this logic board. Post each measurement.
