My kid was trail riding (more like mudding) and the sportsman died. It would not re fire. A friend of his reached under the cowel and "wiggled" some wires. Kid was able to restart. Again he was riding and it died – of course at the bottom of a mosquito infested ravine. Charged the battery, reinstalled, sportsman simply clicked. No start. 2 more attempts and the battery was dead again. Thoughts on where to start investigating, please.
