I forgot to add something about the outback light. The motion sensor has a
blinking red light (to indicate when it has the sensitity enough to pick
something out, or the range; to help aim it / set it up). Its blinking when
I move around now, and I'm pretty sure it doesn't have a battery, or any
need for a seperate power for just that, on just it. So I dunno. What to
think about it, or its connection, if any to the receptacle.

If the motion sensor has a LED that lights, it is getting power. If the
LED flashes in response to people moving in front of it, the motion
detector part of it is working. If the lights don't come on at night,
then

1) the bulbs are burned out, or
2) the bulbs have poor contact in the socket, or
3) the photocell that disables the lights during the day is broken, or
4) the triac or relay that switches power to the lamps is broken.

To eliminate (1), remove the lamps and try them in another socket. If
they work, look in the socket and clean if necessary (after turning off
power to that circuit!). To check (3), switch the motion sensor to
"test" mode so it will light the lamps during the day. If they come on,
it's the photocell circuitry that's dead. If test mode doesn't bring on
the lamps, you have problem (4).

I just replaced a motion detector a few weeks ago due to a dead
photocell. That one worked when it was dry, but not when it was rainy
and humid for a few days.
