Hi, I am trying to turn off the system failure light and battery light, My alternator die I bought new one and replace it, it work perfectly fine, but the warning light stay on, I try to disconnect battery didn't help. Any help?

 

Get an OBD-II scanner and erase the code. Do you have access to a scanner? Looks like this:
Obd-II - Harbor Freight Tools

Are you in the US? Parts stores here like Autozone will have them available for you to borrow to check the codes and erase them for free.

 

But this is not check engine light, I have obdII, this is warning light!!! and battery light.

 

Oh, misunderstood you. Are you sure it's fixed then? You might try disconnecting the battery for 10 or 15 minutes to see if that resets anything. Just a guess.

 

I did try with the battery, didnt work out, the alternetor is working normal, I am driving car for a weeks.

 

I feel for you. I'm having interior lighting issues and can't seem to find what's common to the system.

Here's a bump ttt.
