Re: motion sensor light stay on
Hi, You don't say what the make or model is, so I will give you the best advice I can. Most motion sensor lights today have a switch or two on them for "on", "test" and then some time like 3 minutes, or 5 minutes. The switch is tiny so it or they are easy to overlook. The "on" position will keep the light on all of the time. The test position does different things on different models but you will want one of the time settings. If this doesn't work for you get back to me with a little more info and we'll keep on it. Good Luck!

Very common issue with motion sensing lights. You can either replace the light sensor which is available at most hardware stores or you can disable the motion sensing feature and just have an on-off light. To disable the sensor, (turn off the power!) unscrew and remove the light sensor (it is the reposition-able box under the light.) It depends on the particular light, but you usually just match up the wire coming into the light from the house and the wire from the bulbs and connect them with a wire-nut.
Just ignore the fact the new device does not have white neutral. While old device has neutral Difference: The new device is rated for incandescent only, while the old device was rated all type of lights including cfl etc. Copy following link for wiring illustrations http://waterheatertimer.org/How-to-wire-occupancy-switch.html Check manual for product rating. You might want to return device and buy one with white neutral wire so it will work with your application.
Light sensors have 2 adjuster screws on them that you can set for you particular situation. One alters the distance that the sensor reacts to and switches on and the other is the sensitivity of the sensor so that slightly moving or slow moving items will not set them off . The bulb you are using will also alter the operation so stick with and incandesant bulb rather than a energy saver.
Reset circuit breaker. Check if you are on a GFCI circuit.
Probably there is no hope, but the sensor has to be removed to replaced, so take it off and hang it upside down and let dry in sun. There is no repair protocol for fixing motion detectors, because there are no replaceable parts, or circuit boards. Cover outdoor electronics with plastic bag when washing house. That includes light and pool timers, breaker boxes, low voltage timers, infrared cameras, motion detectors, alarm boxes, etc. Should the power wash contractor know this? Maybe yes. We never covered things when washing houses, and we washed 100s per year, but I told the guys not to put pressured water directly on any outdoor electrical system. Can you prove that the sensor stopped because of washing. No. The unit could have simply stopped working.earlier that morning, without provocation.
If new, then it could be faulty. If old, then may have water damage.
POSSIBLE CAUSE 1. Light switch is turned off. 2. Flood lamp is loose or burned out. 3. Fuse is blown or circuit breaker is turned off. 4. Daylight turn-off is in effect. 5. Incorrect circuit wiring, if this is a new installation. 6. Light control aimed in wrong direction.
SOLUTION 1. Turn light switch on. 2. Check flood lamp and replace if burned out. 3. Replace fuse or turn circuit breaker on. 4. Recheck after dark. 5. Verify wiring is correct. 6. Re-aim light control to cover desired area.
The motion sensor unit shorted to due to rainwater infiltration, if its like the last half-dozen motion sensor units I opened up. Take the unit down, open up the sensor unit head, and if its got moisture inside, you know why it quit. If not moisture, then they sometimes do what all electronic devices eventually do, they fail due to 1 of the components reaching its failure - every sensor has an MTBF (mean time between failure).
Good Morning -
Make sure the bulb is point in the right direction and don't use an incadescent? bulb like a 60 watt bulb.
make sure you use floodlightor spot light bulbs so theydon't shine on the sensor.
Have a Great Day!!
