I have a 2011 Pro RMK 800. I keep burning out my high beams. I checked all the heat grips, they are fine. What I am seeing is when I shut off my heat grips, that is when my high beams burn out. When my heat grips are on my high beams will work. I checked grounds, totally disconnected all my heat grips, checked my relay and checked my voltage regulator. What else can I look for?
