Motorcycle Repair Questions? Ask a Mechanic ASAP
the charging system is not working. when the atv is running normal, you should be getting 13-15 volts at the battery while running above idle speeds. your atv most likely is not doing this. the common fix for this is the regulator/rectifier. it is bolted onto the frame toward the rear of the atv. there is also the possibility of the stator going bad, but on this atv it is very rare.
