Yeah enblethen. The ground wire is factory, so I don't know. I'm going to need to go to an RV dealer for another molex connector and have them bench test my board, so I'll ask the RV service techs about this. Weird though how the wire is only affected about 8" forward (towards panel) of the connector and about 2" back (towards furnace) of the connector. And of course the connector itself. I'm wondering if the connector went bad, and/or a bad factory crimp that has finally manifested itself(?). Anyway I'll see what the techs say and let yas know.
