Greetings,

I'd almost believe that perhaps the connector for the neutral safety switch has either water in it or the switch itself has gone bad. Pull the connector off the switch and try again and see if that doesn't get you on the troubleshooting trail. If that works, then pull the small cover off the connector to ensure there are no wires that have disconnected from their terminals. I'd also see if there isn't water or something that could be causing the short at the connector plug.
