Downlights stopped working

[jp butterworth]

Hi

Hoping for a clue.

All 5 Down lights in hall stopped working suddenly after fine for 8 yrs.

As far as I can see it’s 1 transformer (35-105w 240 to 11.5v) with 5 20w halogens in parallel (daisy chain?)

I assumed transformer issue so replaced like for like no joy.

When I switch light switch I register a current at all lamp fixtures and no current when switched off ( I haven’t got a multimeter).

The smoke alarm may be powered from this ring I’m not sure (battery and mains).

What else could it be?

The circuit breaker hasn’t switched..


Thanks

Sounds a Strange one, have you got anything you could temporary wire in using the power input into the Transformer such as a light just to confirm it is live?

What have you used to determine this 'current' exists, if you haven't got a multimeter?

One possibility - old transformer failed and destroyed all of the lamps. Try replacing at least one of them.

It is a waste of money to randomly replace items without first checking they are faulty. Money would have been better spent on a multimeter so you could have diagnosed the fault.

It won't be a ring. Rings are only normally used on power circuits.

There are several things it could be. How about a poor connection at the first lamp. You can test individual lamps with a multimeter. You can check input voltage to the power supply (not a transformer by the way) with a multimeter. You can't check the output voltage as the frequency will be too high, but you can check the continuity of all the wiring. Guess you need to buy that multimeter.

It is unlikely to be a ring type circuit, but not impossible.
As you say, "normally".
