a1286 820-2850 Charging problem.

[reassor]

Battery is ok - can charge it on diffirent mobo (not same model - BUT simillar stuff around battery port.

So to the wierdness now.

Battery in it works fine - shows how much is charged etc.
When i plug magsafe it sits at green then jumps to red for few secs and back to green (mac on or off) wierd part is when it switches to red my psu shows over 7amp draw but stays at 18.5V and watts do not go up O_o.

On diffirent mobo (this one is not starting - dead gpu) it never goes over 3 amps.

Any obvious susspects?

I might be a morron so dont be rude

Burned part of isl - curent sensing 10 ohm ressistors + 1 mossfet.

Still no charging - battery has around 70% - no boot from battery
No boot from charger (unless i hold power and put charger in then release power after like 5-10 sec
