Battery trouble - 7.4 volts to house batteries...

Did some more checking. sorry for my confusing information. I realized earlier that I incorrectly measured my batteries. Since they are in parallel I did it wrong. Having said that, I have confirmed a voltage at the batteries of 11.4 wether I'm plugged into shore power or not. If I start the generator then I do get 14 volts and can open the slide out. So it appears that the converter may not be sending out a charge??? I'll go do some prodding around on that.
