i bought a 97 300 fourtrax the other day that needed a cdi box. i put one in it and it fired right up. well next i noticed that none of my lights wouldnt work including headlights and neutral reverse and oil temp light. i checked the battery and it didnt have a drop of charge. when i went to drive the atv it would die when you got it past a idle. I put a battery in it and it would drive but not like it should seemed very week and still none of my lights would work. can anyone help?
