Hi,
I have an A1466 that stoped charging the battery, and now only powers on without battery. Already replaced the battery without success.
All voltages on U5110 are ok. All voltages on U7100 seams to be OK. Shel I replace SMC ?
Can you help?

PPBUS_G3H voltage w/ and w/o battery connected?
Is the battery at least recognized?
Check voltage and diode to ground at SCL/SDA lines.

Hi,
The diode readings on SCL/SDA on the battery conector are OK (0,530V).
When i first replaced the battery, it was recognized, but after one day, when the battery run out of charge the mac didn't power on again. After iI disconected the battery it sarted working, but only without the battery conected.
I'll measure PPBUS_G3H because I forgoted

J6950:
Diode:
SDA= 0.531V
SCL= 0.351V
Voltage:
SDA= fluctuates between 0 and 3.4V
SCL= Fluctuates between 0, to 3.4
Withou battery they are 3.4V

PPBUS_G3H
WITH Battery = 8.5V
W/O Battery = 8.5V
