So I have no green light on the MagSafe charger.
I followed the rails till I arrived to D6905 which has 3.42v in pin 1 but 2.7v on pin 2 on Logic board # 820-2530.
Should I look for new D6905? (looks difficult)
Can I run a jumper from somewhere and skip this diode?
Already replaced all resistors and capacitors looking bad.
Thanks in advance.

Did this system have a liquid spill?
The MagSafe LED is driven by SMC, I’m not sure I follow why you are focused on 3.425V G3Hot.
I would go back to PPVBAT_G3H_CHGR_OUT Q7050 si7137dp as I’m suspecting that’s your issue.
这个答案有帮助吗？
Stopped turning on 2 years after water spill.
I had 0v everywhere, i replaced r6905, c6990 and c6999 now i have 3.6v and 17.2v on both sides of r6905 and then i found that on d6905 thats why i thought problem was there. Q7050 and that area looks alright.
Q7050
All pins have 1v less pin 4 which has 0.22v.
Thats it?
I would start there.
So that comes from CHGR_BGATE in U7000.
U7000:
DCIN 0v
ACIN 4v
VDD 0v
PP3V42 G3H 1,7v
Btw thanks for your help man
