820-2390, not charging the battery

[yobad]

820-2390 was dead no PPBUS_G3H fixed by changing U7000, now it start and load the osx but the battery is not charging
PPBUS_G3H 8.42 on F7040/41

CHGR_ACIN 4V
CHGR_ACOK 2.5V
R5280 is ok 1k
R5281 is ok 1k
SMBUS_BATT_SCL 0.5v diode mode
SMBUS_BATT_SDA 0.5v diode mode

CHGR_AMON 0.048V without battery
CHGR_BMON 0.053v
The resistance between pins 17/18 22.3ohm
The resistance between pins 27/28 22.3ohm

i am not using the original DCIN, i use 820-2565-A

Are you sure about 17/18? If so there?s the issue

"The resistance between pins 17/18 22.3ohm"
Is correct, older boards use 10 ohms series resistors there.

Do you get green light on Magsafe?
If not, SYS_ONEWIRE issue must be solved.

Did you try known good batery?
Also check disconnecting BIL.
Any history available, liquid signs?
OSX recognizes battery?
Post SCL/SDA volatge too.
