I need help in identifying the cause of the draining of my battery. I just purchased a new battery about two weeks ago from WALMART EVERSTART #49 and the battery kept draining on me. One morning it was completely dead and I have to jump start it with my other vehicle in the garage. I noticed though that the shifter light was still on even after I completely turned off everything in the car. I had being jump starting the X for about 3 times now for the period of 3 weeks. Please advise.

Many thanks,
