2015 high lifter no power at the key

Need help? I have a 2015 high lifter with 6 hours on the machine. Never had a problem. I wired after market light bars to the winch accessory lug so that I would only have power when the key is on. All wiring had relays and fuses in the harnesses. When all 3 LED lights were on at once the lights stut off. I must have tripped something. I have no power at the key or any dash accessories, and I haven’t found any blown fuses. Battery is fully charged. Where do I look to find the problem.
