Just purchased 2006 Leisure Travel Van Free Spirit 210B Sofa, 2007 conversion on Freightliner. VIN# WDYPD744965903854. Came with wrong and smaller chassis battery. There were two wires, near the battery, that were not hooked to the battery. I have installed the correct size battery. Where do I attach the two extra wires? Have 2 new Coach Batteries. Coach Batteries charge on shore power but do not charge from the engine when I drive. There may be other things that do not work but I have not found yet. I am so happy I found this site. Hope to drive from Key West, FL to Vermont next week.
