I recently had Harley Davidson replace my speedometer and when they returned it to me I immediately had power issues and the bike kept shutting down on me. I returned it to Harley and they said it was the voltage regulator and so I had them replace it. Since then I have continued to have power issues. The lights fluctuate and my speed drops randomly. Sometimes it gets real bad and if I shut it off and back on it seems to improve. Any help would be great as I am tired of paying Harley to not fix my bike.
