Pete, I don't have a voltage meter and not sure I'd know how to use it if I had one, but I'm going to try to pick one up at Home Depot today. There's a digital meter just inside the RV door that says Xanttec (or something like that). It shows a battery input voltage if 14.2. I don't know what it the reading is while trying to retract because the buttons are non responsive.
