I like followups on here. This is mine.
A while ago I posted that my yard light suddenly quit. Not the usual
dying bulb syndrome, where the light gets dimmer until one day it just
wont light. Mine quit and that was it, A new bulb and new sensor did
not fix it. I finally convinced myself to go up the pole (I hate
heights). Several months of stumbling around in the dark was getting
tiring. I bought a complete new fixture and replaced it. I now have
light again, and it's brighter than the old one (same wattage bulb).
Anyhow, I found the problem with the old one. One of the wires inside
the fixture that goes to the socket for the sensor had come loose.
How in the heck that happened is beyond me. That fixture has been up
there for 8 years, the wind might shake the whole fixture, but not the
individual wires inside. Although there was a huge blob of dead bugs
inside, so maybe the weight of all that crud did it. I have not yet
figured out if that wire is molded to the socket or if there are
screws. I'm waiting until I get my air compressor back (from a
friend) so I can blow out all the crud and see what's in there.
I never would have suspected this !!!!
