No power to head lights and starter Gator HPX

Troubleshooting. New battery. Still no headlights and only hear a soft relay click near starter when I attempt to start. There is good 12v battery to starter. Seems to me the clue should be both the headlights and starter not energizing have something in common..Any know what the three relays do underneath the dash on a 2006 Gartor HPX? How can you test relay? Got good 12v to starter. As I remember, headlights go on as long as the key is on and the switch for the lights is on. I got no power there so it has to be something other that starter. Not sure where to test now. have both meter and probe test light. Help please.... Steve

OK pulled the ignition switch and put my test light across the top two post and it fires up the starter. Not sure why I still have no headlights...
