[Solved] PINOUT FOR DELL Y9N00
CAN,T FIND IT ON THE DEVICE PART NUMBER LIST
+1, C3, D4, SP6, -9
thanks i got the reading,
please i need your help from the reading i showed you before about my DELL Y9N00 ,i believed you can tell that the battery is down as in (not good)
i tried unlocking the battery but the cells are inbalanced and overdischarged so open the battery
in other to charge the cells and balance them, to unlock the battery
i charge them through the outlet that the arrows are pointing at in the picture above so that i dont have to reconnect them after , but when i done with charge and balancing the cells i went back to reading but i couldn,t get a reading
i said ok let me check the fuse maybe the fuse is blown , i checked and the fuse is blown so fixed it up but up till now i haven't gotten any reading
please i need support
If you have accidentally reversed polarity during charging you might have fried components on the PCB or the chip.
Try to disconnect all cells wait 30min connect them again and try to read data again.
If there are no readings again probably the PCB is dead.
Reverse polarity is wiring - to + and + to -
If the PCB is dead as you said, is there any hoping of reviving it
There is always a way but it's not worth the time and effort to do it.
Also you need excellent knowledge about electronic curcuits which i assume you don't have since you asked me what is reversed polarity.
Just forget about it, and next time disconnect cells before precharging them or proceed with caution.
