Question Post light with sensor alternates on and off in daylight

Hi everyone, I'm new to this forum. My husband and I have a strange issue that has us both scratching our heads...

We have a post light out front that wasn't working since the day we bought our house. We replaced the lamp, light bulb, and light sensor. Now in daylight it alternates on and off every 20 seconds or so, and in darkness it stays on. Could the sensor be faulty to cause it to alternate when it should just be off? I just hope we didn't mis-wire it or something!

Any feedback is appreciated!

Did you use an incandescent bulb? If your sensor has no neutral a CFL bulb will blink like that.

I was thinking along those lines at first too. We tried a CFL (60 watt, 900 lumens) and an incandescent (100 watt). It blinks with both bulbs.

Actually I should clarify: Our sensor has a white wire (which I believe is the neutral). Here's a picture of the wiring (sorry it's blurry). I'm starting to believe we switched the red and black wires coming out of the sensor. http://i.imgur.com/aN0g1gO.jpg

Did you use an actual lamp post photo cell....the one that mounts thru the pole ?

Those usually have a neutral connection on them. It sounds like you may have a defective photo cell.

While not written in stone most times black is power in and red is power out.

Indeed the red and black wires were switched. The sad thing is we had wired it exactly the same as the old one was. Maybe that's why it was burnt out... heh...
