Finally found the perfect RV for me and have been busy with renovations but have encountered a perplexing problem with the electrical system. This rig has an Intellitect Power Center and has a switch located near the entrance with two options; Store and Use. I have shore power hooked up but the coach battery still drains down fairly quickly and the truck battery drains as well at a slower pace. Everything works fine when the batteries are charged but thought the power center should keep the coach battery charged as well. I've been mostly using the 110 plugs for power tools and such but need the DC system to run the furnace (cold down here in NC this week). Any ideas or thoughts. I'm hoping I don't have to replace the power center.
