Help with led problem!

Hi, sorry, been mad busy!

thanks for the replies.

the cables from the loft are a 2 core aluminium or steel conductor with a clear sheath, I wouldn't want to put 230 down them.
the new lights have built in drivers, but as I didn't want to put 230 down the existing cables, I took the drivers out of the fitting and located them in the loft! There are each light is wired separately from the loft, and each has its own driver. The first lights cables are about 800mm long and the second lights cables are about 1500mm long.

my voltage tester is a megger.

thanks

Do you think you could repost this when you have sobered up?

Haha! Yeah defo a good policy to keep quiet sometimes. However your electrical knowledge, along with numerous other members on here, is excellent, and just shows how complicated electrics can be in my view. When I first started the CG 2330 approx 11 years ago, I never anticipated that the breadth and depth of electrical theory/practical work would keep me feeling like I know very little still! That is partly why I find forums like this can be fascinating.

Would it make you feel better or worse to know that I started the 2330 (and consequently my apprenticeship) at around the same time?

So you took the fitting apart and put a longer cable between the driver and LED than it was designed to have?
It could be that the added impedance of the cable is the problem.
Or the fact they come on when you apply the test probes could mean the terminations are loose and only make good contact when pressure is applied.

Worse, much worse!! You must have had a better boss to learn from! Mine was pretty carp TBH.
