Greetings from Cape Cod on a beautiful Labor Day. I have a 1979
Sovereign Twin (?) with a rear bath. This land yacht will travel again. It now provides shelter on a very nice pond front property. The Airstream has been neglected mechnially for a while. I've replaced the Univolt and the fuse box. I have an INTELI-POWER converter. The fuse board, I don't recall the brand, is smaller, less capacity, than the original. As it no longer will travel I've eliminated both battery and exterior travel lights. Now I can't get the 12-Volt to fire up. I have 110 volts at the converter and 13 and change volts at the fuse board. I have attached photos of the installation. I'm a rookie at Airstream electrical, much better with residential systems. HELP.
