HI...I am posting this for a friend who has a 99 FLTRI Road Glide with a ferring. The headlight connectors melt off at the bulb, but the bulb stays good. Three have melted off so far but not all on the same side. He says the voltage checks out when tested. The wiring harness splits off and goes to the lights but the harness never has burnt, just his connectors at the lamps. Any help would be nice.
