l have a 325 trail boss and when l went to start it it was getting no power to the starter so l installed a new battery. l still had nothing you cann start it using the pull cord and it will run but none of the lights will work? l assume it is the fuse but l have still not located them can someone please help and tell me where they are located. thanks!

l would assume your huess is correct.
and l would assume its main fuse.
i havent found a pdf, but l can tell you that most are under the seat
not far from the battery. the main battery cable if followed will take you right there! a link for a manual is http://themotorbookstore.com/polaris-atv-manual.html
