We have a home built in 1947 and would like to replace the old chandelier. Problem...when we removed the old fixture there were 5 wires exposed from the box. One of the white wires and one of the black wires appear to come from the same source, and the remaining three (red, black, and white) appear to come from another source. The new six light chandelier only has three wires total; two black and one copper (ground). None of the instructions included with the new fixture show anything like we have uncovered. Any help would be appreciated. I have taken pictures of the exposed wires and would be happy to email to anyone who would be willing to help. MANY THANKS!
