I have a Fushin 90cc ATV. A full battery will drain down to nothing in about 20 minutes. No lights on, no accessories on etc. I cant seem to figure it out. Any suggestions? Thanks

 

the battery drains when while running? or just sitting or what?

 

As soon as the battery is connected it immediately starts draining, ignition off. I spoke with a mechanic and he suggested checking the recitfier. Sure enough, that was the problem, it was shorted out. After replacing it, no more problems. Thanks!
