This has been frustrating me beyond belief. I have a 2018 sportsman 570 and 450 sportsman. I am trying to put a 12 inch 75 watt light bar onto the quad. I have a fuse and a relay in the wiring harness. When I hook the light bar up to the atv battery, the led switch turns on but the light bar won’t turn on. Then I hook it up to a different battery, led switch light on and light bar on. I though it was a ground issue on the atv so I hooked the ground up to a different battery while the hot wire was in the atv battery and still nothing. Can anyone please help me???
Thank you
Thank you
