Early connectors were made of a type of nylon, a silly choice as exposed connectors like that on aircraft have switched to phenolic or similar resin connectors decades ago for the same reason. My '95 SP connector to the headlight had this same thing happen. But it was while riding home night across the Arizona desert! Melted the damned thing good.
