My 2004 polaris scrambler 500 started to backfire ,then i was able ti limp it into the driveway and it died . I tried to start it but when i turned the key there was no power to the rest of the quad . my winch still worked but its wired straight to the battery . I had noticed a sound coming from the sylenoid by the battery during previous times i started the engine but then i would turn off the head light and it would start fine . I replaced that but still no dice with the rest of the system . Anyone else ever had this problem ???
