My 2007 TRX420TE/FE Fourtrax Rancher 420 ES/4X4 manual shift died while riding and will not start. We had a family gathering where several adults were taking turns ridding the ATV. Late in the day I see one of the guys pushing the Rancher back up to the barn. He said he was riding along and it just died, tried several times to restart and nothing. There was fresh fuel in the tank, the battery had a charge and we could only hear a faint click from under the seat. Thinking it may be the battery I charged it overnight, cleaned the connections and tried starting it again with no luck. Any thoughts on how to troubleshoot would be appreciated.
