Well i got the battery to charge to 13.8 VDC.
Had the RV disconnected from AC, but the battery fully charged and connected. I had zero power inside the RV. No lights, no fans, no slider.
Plugged the RV into AC and the lights fans and slider now work.
So my guess is the battery is disconnected from the lighter loads, but somehow a relay kicks in the battery to
drive the slide out motor. Makes sense because with a dead battery, the slider is dead. AC alone wont activate it.
RV dealer is huge, but they seem to be weasels. I will try to fix it myself when I can walk again. I don't want to take it there. At least I got the slider out so we can clean it out for the season. I guess in a pinch I could use jumper cables if the battery dies. I can take a trickle charger on trips. Half a$$ed repair, but I got other stuff for the moment to do.
