[SOLVED]820-3115-B no charger light

Hi guys!

I have a motherboard which has apparently been to another repair shop but they couldn't do anything with it.

No charging light is the issue. Works fine on battery though.

CHGR_CSO_P, CHGR_CSI_P and CHGR_CSI_N are only showing 1.2v.
CHGR_VCOMP and CHGR_ICOMP 2.8v (is this right?)
CHGR_BGATE 1.39v
PPDCIN_G3H_INRUSH_FET about 1.3v but drains slowly.

Any help greatly appreciated.
 
Magsafe board(s) confirmed working.

C7005 pin 1 16.3v, pin 2 0v

How do I check if PP3V42 present on AC only? I checked R7012 pin 1 and it gave 3.4v with just charger, just battery and both battery and charger plugged in - is that what you mean?
 
I got this board working. I replaced ISL6259 and also had to make jumpers between C4903 and C4908 but also a really long jumper between C4902 and C6999. Is there a physically shorter jumper I can make than that?
