OK finally got around to looking at the aisle light connections for the old grab bars. They did not complete a circuit. All four positive and and four negatives paralleled off the main wires feeding the stair rope lights. I have removed them all. The circuit continues into the stair rope lights as before. The aisle lights still do not work. The panel lights for the aisle light control remain green all the time regardless of the position they are in or where they are pressed (front passenger panel or bedroom panel). Any thoughts here? Maybe a fuse? Does anybody with a CC electric diagram know which card controls the aisle lights?
