Help with ceiling light issue

[Doggit]

It is possible this light was the first one on the system, and so the live fed the other lights, but wasn't wired down to the switch and back properly. But if the connector block was acting like a ceiling rose, then there'd be a red feed in, a red feed down to the light switch, and a red feed on to the next light, so either there's a wire missing, or this is an adaption from the original ceiling rose, and just wired wrongly. Ericmarks pictures good, in that it shows the neutral coming back from the light switch, and then feeding the live side, but again, there's no live and neutral going to the next light.

But Ericmarks picture should give Mastin an idea to work from, and if he has a simple mains neon screwdriver, he might be to check which is the permanent red live coming in, then link in the second red live to it, and determine which s the live return from the switch, then get back to us.

It's possible that there is a ceiling rose above the connector block, that one of the live wires has not been fitted back in properly, one of the live wires has broken inside its sleeving, or that the return live (black coloured wire from the switch) has been wired in to the neutral, so that there's two lives, and no neutral - which could explain why all the lights blew.

Like previously mentioned, you need some electrical test equipment.
There is absolutely no point continuing further without it!
You cannot identify conductors, you cannot prove continuity, you cannot prove voltage, you cannot prove polarity, you cannot prove things are anything like safe to work on or put circuit into continued service.
Please take notice of the advice offered, back to the naughty corner with you!

4/5 or so unmarked black.circuit breakers

If these have levers then these are the MCBs

All acemdemic as he has

called out an electrician who is supposed to be coming tomorrow (Firday) afternoon.

I wonder what he found…

AS above, my guess is the switch is fried. There's an easy way to determine this.

Maybe, but a knacked switch does not account for a broken circuit.

Eric, that is a brilliant bit of photo editing.

It is, indeed, very impressive - but he failed to remove the shadow of (what was) the second black conductor on the left

Kind Regards, John
