Hello all,
This is a long explanation, but basically I am looking for what could cause a light bulb to light up only dimly. Could it be a short to GND or some other leakage?
Here's the situation. I have a three floor apt. building with a common panel feeding a lighted fire escape. They are not switched, always on for safety. On this same circuit, before reaching the stairwell is a single light in the basement. No problems with this light. There are 2 other leads I have not yet verified where they go (either disconnected or feeding something I am unaware of). On the outside of the stairwell is a spot light with a motion sensor to go on at night when you go around back. The problems started with the spotlights remaining on all the time. Not knowing the age of the sensor I replaced it, wired as directed on the package. Since it was summer, I don't know if it ever worked properly. I was unable to test it fully. Later, I noticed the spots were very dimly lit. The stairwell lights were full power and lit properly. I removed one spot and the other would light fully. I left it that way, but still unsure if the motion sensor is working properly. Again weeks later, now the lights are out in the stairway. I've been using fluorescent bulbs. The bulbs light up in other sockets on another circuit. I replaced one with a regular incandescent and it is barely lit.
I test the motion sensor by turning off the breaker, then turn it on. The single spot lights up brightly, but the stairwell lights are out (except for the dim incandescent). Then after 2 mins. the spot goes out and so does the dim bulb!
The stairwell lights are NOT switched by the sensor. I have removed the sensor completely, and these bulbs are still not lighting up.
How can the sensor affect the stairwell lights? Why would they not get enough power to turn on completely?
Obviously, I am not an electrician, but I do have a clue how this stuff works. I'm about ready to re-wire the darn stairwell.
Any advice?
