I picked up this atv for $50 and fixed up engine problems last summer and rode it all summer. Then it stopped running in creek. There is a little box connected to a 4 pin harness right beside the battery. That just kept clicking softly when I jumped it off from my other atv. Is it a cdi box or starter fuse or some kind of regulator? I can't find anything about it because this 2 stroke atv is rare. Need help please!
