i have had this prob since i bought the tractor. it would run for a while and than would not start. i thought it was the battery, but today i took it off the charger and started it, than i took the cable off the battery and it died. so it's not the battery it's something else. i took the alt in and they said it was ok. all the wires are hooked up, at least i think they are. it has a 12 volts system so i don't know what to do about this prob.
