19 Street Glide Special, notice the radio is clearer when I hit the kill switch than when the bike is running, I did change out the headlight bulbs to LED with the fans on them, did that when I picked the bike up so do not know if the radio was that way before the bulbs or not, but why when only the engine running? The lights are still on when you hit the kill switch. Appreciate any clues, bought the bulbs at the Harley dealer.
