Hello every one… I have kind a s stupid question but here goes. I have a 2003 polaris trailboss 330 that is all original. The battery doesn't charge any more what the proper diagnosis step for such a concern? Any help or advice would be greatly appreciated. Thanks again dneuhof

 

Check that you are charging around 14 volts back to the battery while idling. Plus it just could be that's it's time for a new battery if it won't hold a charge. You can have the battery load tested at any auto store. OPT
