battery....

Those quads need a fully charged battery to run correctly. It needs a New Battery. If you put a battery tender on it through out the year it seems to keep the battery at full. I've heard of people buying brand new batteries and they didn't work because they were defective(didn't hold a full charge). Just like a car battery=If the charge gets to low=the alternator won't be able to recharge it because the machine will require most of the battery power to operate the computer. The battery will allways stay low unless you charge it fully and test it to make sure it holds charge after you ride it. Don't forget to check the fuse by the battery....
