I have a 2004 sportsman 700. I cant get the alt. to charge or even try to charge the battery while the engine is running. Tested it at the battery, and all i get is battery voltage which isn't much because of an already weak battery. Also all of a sudden the 4wd indicator on the screen doesn't come on when you turn on the switch, But I haven't confirmed that the 4wd isn't actually working. Any idea or suggestions would be greatly appreciated. Is there a fuse that controls these circuts that could be bad maybe?
