Here is my problem.. I bought a DongFang DF250chb about 3 months ago and everything was running good and then the other day my battery went dead and would not hold a charge so I bought a new one thinking that the battery was the problem. I did everything i was told to do before putting the new battery in my bike. After charging the battery for like 4 and a half hours and letting the battery sit for an hour afterwards. I put it in my bike and rode around for an hour and the battery went dead again and will not hold a charge. Now my question is, whats causing the problem the stator or rectifier? Or could something else be causing the problem?
