820-3435 - MagSafe LED off. No recharge.

Good evening,
I have a MacBook Air 11 "A1465 EMC 2631 where the MagSafe LED is off and does not charge.
The Mac had suffered a liquid damage (coffee), and I already changed the battery because the other was HS
But the MAC refuses to charge more than 8%.
On Mac OS X, the battery icon is lightning-free and indicates 100%, but if I unplug the charger, the Mac turns off.
If I run the diagnostics at startup by pressing D, the Mac asks me to connect the charger while it is done and tells me 8% this time for the battery.
In all cases the charger LED is off.
I tried to change the card of the connector MagSafe, the one that is connected later to the motherboard, by a MacBook Air 13 "because same connector but same problem in the end.
I have a voltage of 8.5V at the battery connector in all cases.
Cordially.

"Check SYS_ONEWIRE line level.
Also check continuity with U6900 from LIO board."
You didn't reply: so no idea if your LIO connector is good...
