I wanted to replace an indoor ceiling light. First, I needed to paint the area underneath the current light, so I removed the light from its brackets and found this wiring. I am not an electrician, but based on the other light I just replaced in another room, this doesn't look correct (for example, the Ground is not attached to anything). Is this correct? How should I wire this instead, if it is not?
I see a three-wire cable that was probably intended to serve a fan as well. The red secondary power wire is capped and unused. That's ok.
I see black and white wires, which are presumably hot and neutral from the switch box, connected to the fixture. That's ok.
I see a bare ground that should be connected to the metal junction box, but not the light since the light doesn't appear to have a ground wire. See Can I connect a wire to a metal box for grounding the device? If there is a ground wire on the light, connect that as well. You can loop the ground wire clockwise under a suitable screw in the box, then nut the two ends.
I see black electrical tape on several wires. This should be removed. It's normally only used as an indicator in modern wiring, but there doesn't seem to be a call for that here. The bit on the red wire's nut may have been intended to secure the nut, but a properly installed nut is already secure. Remove all the tape with this possible exception. If you find damaged wires, that's a topic for another question.
