I am trying to change a light fixture that had fried. When I took apart the fixture I noticed red black white and neutral. The fixture has 3 places to connect and no other wires are coming in to connect other lights. If I connect the Black and the white there leaves the red. There aren't 2 white wires coming in so I can't wire the 2 together and then wire the black and the red to the light fixture. When I turn the light on the and hold a power meter to the wires it goes off on the black and white not the red. Help

First off the white is the neutral so what's the wire color of the one you called neutral, is it bare or green. Any chance you have a second switch that controls this light? Your new fixture will have a black/hot, white/neutral and a bare ground. I can take a shot at telling you how to connect your wires but tell me about a second switch first. Is there power coming in on the red wire, ever?
