The 3 wires coming from the fixture I have connected the blk to blk what to what and I thought the oter was a ground so I connected it to the ground coming from the junction box there is also a red wire coming from junction box that was capped off. The light won't turn on. Any help would be appreciated.

Thank you,

Do you have black, red and white or is there a green or bare wire

Most ceiling fans have 4 wires. Black, White, Blue and Green (or bare). What do you have?
