Hi,
I want to replace an outdoor PIR detection light with a simple non-detecting LED version.
When I removed the PIR light from its terminal block and started measuring voltages, I became confused. I was expecting some kind of turn-it-on and get 240V arrangement. Instead, I got strange voltages when the switch is turned OFF, and I have no idea what is going on. So, I am hoping somebody here can offer a clue?
The light is being replaced because it no longer works due to ingress of water, I think. That said, the wall-mounted terminal block, as shown in the picture, seems completely dry.
I have included pictures here and a diagram to show the voltages when the switch, inside the house, is turned OFF and ON.
Any thoughts will be appreciated.
Thanks.
