I left the head lights on for an hour ,after switching them off ,I started the car ,it starts.Later in evening I saw the cabin light was On too ,when I try to start ,can't ,seems battery drain .So I stop a taxi and tried to Jump ,but no success .took the cables off from my car battery and again try to jump but no result .Only few sounds under the dashboard like relay and sometimes something rotating .

This happened once before also few months back .
That time I did the same for 2 days ,but can't run .than the third day when we tried to jump it with another battery (not another car) it starts from the first try .I never understood what happened .Maybe I left the cables off the battery ,previous day and that helped to reset something like a computer .

Everything else runs great ,never no problem with anything like starter ,generater etc.

Check your connections and grounds, mainly the negative battery cable, make sure they are clean and tight.

Thanks Badpenny ,I got it working ,the problem was Jumping cable .One of the wire (Negative)was not good enough to take load .
