    Has it been raining in your area, cause thats what the problem sounds like, cap board is wet, or has a loose connection

    They would have replaced the power board, however, I don't think thats the problem, I believe its with the connection plug between the the engine and generator system. Firewall left side. I believe its corroded. If you unplug it and replug it, that should reseat the pins. Dielectric grease works wonders at this point. I'd be doing this real soon, before the power board gets nuked
