im new to atvs this is my first its a 1986 honda 350 fourtrax .. the battery will not charge it just recently began to do this i had rode it for many days often hours at a time cut it off and would crank right up then after a light day of riding i noticed the dash lights got real dim wouldnt crank kick started fine ive read it may be the stator or the rectifier im just wondering how to trouble shoot and test to figure out which one is the issue .. thanks
