polaris xplorer electrical problems.

Hi I was given a 2000 polaris xplorer from my grandfather thats been sitting around for a good year. I couldnt get any electrical components to work. so i replaced the battery in it with no luck. then i replaced the starter solenoid. well with the solenoid replaced i don't get lights until i use the electric start. it doesn't turn over but it seems to connect all electric components. Would anyone know what could be wrong or a place i could start looking. any info will help, thanks
