yes this is good 21,2 ohms But if I put it in diode mode I have continuity between its pins and I have checked with another board and that should not happen

Pins 27/28 are connected through mentioned resistors.
If you disconnect any of R7121/22 shouldn't have conntinuity.

 

[lincev]

remove r7121/22 and solved

If I put in just one, everything is fine, but if I put in two, I have continuity again (resistance in good condition from other logic boards)

 

[2informaticos]

Put back the resistors.
Be sure to get correct ohm values between pins 17/18 and 27/28.

ok now I have :

pins 17/18=04.9 (scale 200)

pins 27/28=20.6 (scale 200)

i have continuity pins 27/28

It turns on, battery connected but when I disconnect MagSafe it turns off. Battery charges and percentage appears

Check battery connector's pins.
Few times I found them broken in the middle.
