Yep your voltage regulator is probably wired wrong or it blue more than likely the one terminal melted possibly due to a ground fault sometimes it's actually something shaking loose considering it's a newer bike I would think something shook loose so double-check all your grounds on the lights also the voltage regulator do you have a battery is it electric start?
These will figure into it, if you go and look check the wiring that goes through the fender and into the frame that is a short spot the wiring can go all wonky in there if the set voltage regulator has a melted terminal or blue out chances are there's a short somewhere
