I put the ATV away, it was running fine. Yamaha Kodiak 450. It was about 12 Â° when I plowed with the Grandkids & then put it away. I store it in an unheated garage. 1/2 tank of fuel & pretty fresh as I use it often to plow snow. Kill switch is in "run" , fuel valve is in on (not reserve) Tried several time then the batt started sounding weak. Pushed it to the heated side, added some "Heat" (alcohol gasoline additive for water in fuel) charging the battery. Ideas?
