Please Help with Outdoor Lamp/ Sensor
Your help on this would be greatly appreciated !
I have just re-wired/ re-socketed a 3-bulb exterior carriage light next to my driveway, since after 5 years' use, the sockets were corroded and therefore were shorting-out bulbs.
But, when re-connecting the light to its (5-foot-high) metal post, that has a light-sensor built-in (a 1/2" diameter, side-mounted photoelectric, brand unknown), I get this result:
> The House Power to the Lamp is fine/ the Lamp is lit when the House Power/ panel switch is on ...
> Unfortunately, the Lamp is lit ALL the time/ regardless of day or night, and will not shut-off on its own when exposed to any dim, or bright, daylight ...
> The only way to turn-off the light is at the house panel. The lamp will go off 100% of the times I manually switch it 'off' at the panel, and will come on 100% of the times I manually switch it 'on' at the panel, no problem there.
I'm guessing either I have the wiring wrong; or, the sensor is broken?
Prior to the re-wiring/ socketing of the rusted-sockets lamp, the on-off light sensor on the post WAS working fine every day and night. Maybe I've somehow damaged it during the re-wiring ...?
Here's the connection scheme I'm currently using to connect the house power to the switch/ lamp.
The House Power source has 3 wires total (Black, White, Ground/ Copper).
The Light-Sensor Switch has 3 wires total (Black, White, Red).
The Lamp has 2 wires total (Black, White).
1. House Power (3 wires total)
- Black Wire ... to Light-Sensor Switch Black Wire
- White Wire ... to Sensor Switch White Wire.
- Ground/ Copper Wire... to Lamp Base/ Housing.
2. Light-Sensor Switch(3 wires total)
- Red Wire ... to Lamp Black Wire
NOTE: There is no "second" Switch White Wire coming from this particular brand of light sensor, as some DIY help-desks have suggested there may be, just the one White Wire coming out.
- White Wire ... to Lamp White Wire (note: it is already paired with the House White Wire attached to this Switch White Wire, per above. That is: all-three White Wires are now connected together, as one.)
- Black Wire (per above, it is connected to the House power's Black Wire).
That's the whole deal.
Right now, there's back-and-forth trips to the basement every night/ day for my "automatic" light sensor lamp to instead be manually set on/ off.
ANY help/ approaches are Hugely welcome ... Thanks!!
