[SOLVED]820-3435-A doesn't see battery

[elcapitan]

hello i got macbook air 820-3435 that doesn't see the battery. Everytime I unplugged the magsafe it shuts off. It looks like my SMC is fried. My diode mode reading on chgr_cso_n - 0.134 & chgr_cso_p - 0.135. I already try replacing it but im still having the same problem. ISL6259 has already been replaced as well. any suggestions?

the battery wasnt been recognize by the OS. During inspection i found the lines SMBUS_SMC_5_G3_SDA & SDL were shorted to ground. After correcting the bad soldering (pin 10 & 11) on isl6259 the battery was back in action. i cant believe I miss tis. Thanks for the input guys!
