Its not my fault finding thread so it still could be that, but I doubt it.

I've posted up another fault thread, I will post up a picture of the fault once you've answered it correctly.

I originally said in post 27 that there could be a fault in loop terminals of rose 1 or 2, but I deleted the rose 1 out of it

Reason: the switch wouldn't work, so we wouldn't know if the dining room light was working if we couldn't switch it on/off.

Well done, with a little help from Paul, you got there, as he said you have both tickled the answer.

It was a broken loop, line conductor had broken. I found it in seconds because the dining room had a stupid decorative metal fitting, hence I knew it would be broken here and not going into the next fitting.

In the real world you use a voltage tester and work from the last known working fitting.

In college you would need to find it using dead tests.

Well done to both, the reason I left it a while was because inevitably given time you will start to doubt your ideas.

Like I said, pretty sure I tickled it before he mentioned anything

**cough post 21# cough**

haha

keep these coming high tower, same to others too. It's a massive help to us all, makes it easier in college and certainly will for the future. Ill always remember this fault as I was up for hours trying to work it out, little did I know I'd already answerd it. If this ever happens on a job ill know what to look at straight away. Little questions like these make a massive difference.

^^^ Agree.

Going by the info given to us in the opening post we know that the living room light is the first on the circuit, we know it works so therefore we know it has a perm Line and Neutral and a functioning perm live and switch live to and from the switch. So it could only be one of the 3 options above. By knowing this and drawing a circuit diagram in your head you have saved yourself a lot of time testing everything, you have narrowed down where the fault could be and you can concentrate on that area only.

In the field we/you charge £xx per hour and it is within our best interests to find the fault quickly and correctly so not to make us look like we are trying it on and getting more money out of the customer. Once the fault is found we can then estimate the time and materials needed to fix the fault and a solid (ish) quote can be given. This is how the professionals do it whilst the cowboys in our industry just pick a number from the thin air and makes us lot look bad.
