Macbook A1466 820-00165-A - wont turn on

[Okrutnik]

Hi,

I'm having issue with this macbook. No liquid or corrosion found on the board. I'm not quite sure what to measure so would appreciate some advices.

Weird thing I noticed is that charging voltage on the battery pin is droping from 8.5v to 0v and than jump back to 3.3v after a while resets again and jumps to 8.5v. I think there may be something wrong with a charging circut.

Unfortunately I've got a non original charger so I'm not able to check what LED shows. However that laptop is working fine as i tested it with different laptops.

I've checked voltage on all the coils and I'm getting voltage only on 2 of them. 3.3V and 8.5V, rest is 0v

Please help guys

Suggest to source an original and recommended charger and test again.

If you remove the battery, any difference with the logic board?
