:confused: Someone please explain the following situation. All thoughts and insults are most welcome.

Problem 1: 2 way switches switching only one 230v downlight. Live and neutral at the jb above in ceiling no problem. Getting 230v. Downlight connected to neutral. Live feed going to switch, I only get 12v. What the [email protected]#k? So light doesn't work. I took temporary t and e from jb to light switch to bypass the switch line, it worked. So it will just need a new switch line.

Problem 2: Light in study worked yesterday. I go there this morning, find fault with 2 way light. I get a call this afternoon "light in study and living room don't work". I go back, take study light fitting down, I find the t and e feeding the light fitting has no neutral but 2 lives instead. Does anyone think the customer is lying to me? I really don't know what to make of it.

This house was an old coach house wired around 15 years ago in my opinion.

Any help would be massively helpful guys. But I have reached the limit today.:confused:

This sounds like a great project - (with your fault finding hourly rate!) as for the 230 at fitting &12 at the switch- I've had that before and it was a crap connection at a JB. keep us posted.

Two lives at ceiling rose means broken neutral - check at junction boxes etc.

Probably been mistakenly wired in series, it happens all the time

Thanks guys. I was thinking about the lights wired up in series but it would mean the study lights would have to be on for the living room lights to be working. And does that mean if a bulb was to blow, then again lights after the blown one on the same circuit would not work?

Would some idiot really have installed light circuits in series?

I agree wit Wattsup.

someone has crossed the neutral and switch return. all lights after that are then in series

you did say insults welcome lol

problem 1 sounds liek youve sorted that

problem 2 id say the switch wire has found its way in to the wrong jb also possibly switches wired wrong along with another loop in loop out jb wired wrong sounds about right if the switch wire has madfe its way to wrong jb.

i have only been up half hour so the best i can do!!

or tbh it sounds like just the loop in loop out jb has been wired wrong and this is why ur getting 2 phase conductors, same thing has happened to me loads when decorators take down lights.
