Do you have a voltage meter?
No reading out the ohm meter for the bulb tells me the bulb is bad. were is the transformer and do you have output voltage from it?
The transformer is in the top of the post. I didn't check voltage yet because I didn't understand the wiring. There is a red, black, and white wire to the sensor. What is the voltage output of the transformer suppose to be and what is the purpose of the transformer?
take volt reading in and out of the transformer and let me know what you get. Does the red wire from the sensor go to the transformer?
I get 120V to the transformer. There are 4 wires to the transformer. 1 goes to the white on the bulb and sensor. 1 goes to the black on the bulb. 1 goes to the red on the sensor.1 goes to the white on the white on the main neutral. The sensor is labeled black is line, red is load, white is neutral
Hello .. the proper wiring for the power would be power white to the white sensor and one wire on the high side of the transformer
black power wire to the black sensor wire
red sensor wire to the other input wire , high side , on the transformer
the other two wires on the transformer, low voltage side go to the lamp holder of the post light
Any thoughts ,, concerns ??
I am assuming that the lamp is low voltage .. that is the purpose of a transformer .. unless it is a flourescent lamp then it would be a higher voltage
either way the lamp is not designed for 120 volts
The designed voltage should be stamped on the lamp .. sometimes on the screw shell .. sometimes on the glass of the lamp
The way to determine what part is at fault is to test with a meter .. a two wire probe meter ..
testing the input power for 120 volts ..
testing the sensor power out red / white for 120 volts when activated
testing the power out of the transformer .. ?? voltage , may be stamped on the side of the transformer
testing the lamp for continuity .. ohms .. to see that there is a reading thru the lamp
Any thoughts , concerns ??
