thanks for the detail and advice. Much appreciated
Can’t find my multimeter. !!
Can’t get up in the garage loft easily.
I have an old dtd sensor which I might try.
Or try the insulation technique.
There are 2 more of these in the back garden. Same galvanised posts. They work on a Dtd sensor and they do work. Not sure why this one is not working!! Any tips please.
Have this outside light in my garden. Not working. Can’t seem to dismantle it or remove the bulb holder. Wire not long enough. Have removed the rusty screw. No movement. Any advice.
Thanks.
