[Problem Installing Light] Similar problem

Separated from: http://www.doityourself.com/forum/li...oom-works.html

I can't really tell what is going on in the pictures to make sense of my current problem and fix it. I have a mess in my light fixture as well, and when I replaced the old light, the entire rooms outlets stopped working as well. Here are some pictures of the housing and wires, there are 2 sets coming from the side facing the light switch wall, if that matters, and 1 set coming from the opposite wall. I am wiring this to a light fixture with 2 bulbs (2 black wires 2 white wires).
edit- the light switch is also single black/white connection.

In the future please no piggybacking. It just leads to confusion. I have started a thread for you.

In all likelihood one cable is load (power out), one cable is line (power in) one cable is switch loop.

Use the voltage function of your multimeter to determine which cable is line. The one that reads 120 volts is line.

Set your multimeter to ohms and with the breaker off and switch on check each of the remaining cables. The one with continuity is the sitch loop. You can verify by having a helper flip the switch on and off as you watch the meter. It should flucuate in sync to the switch from continuity to infinity.

The remaining cable is load.

At the ceiling:
  • Remark switch loop white black or red on both ends.
  • Connect remarked switch loop white to line black and load black.
  • Load white, light white, and line white together.
  • Light black to switch loop black.

At the switch:
Black and white to the switch.
