Kitchen Lights - Weird Problem
 
Hi guys, wonder if someone can help me.

I live in a relatively new build house (6 yrs old). It has low voltage spot lights in the kitchen. The arrangement is two banks of 8 lights with a switch for each bank.

One bank is working perfectly whilst the other will not switch on at all. I have replaced all the bulbs (all 8) and turned off the mains and each separate circuit. This has not rectified the problem. When the light switch is flicked for the faulty bank sometimes the whole bank flcikers for a split second but they will not light.

I feel that I have investigated as far as my limited knowledge allows and hope that someone has an idea of what is up and what I need to do.

Thanks for taking the time to read. Look forward to your comments.

Cheers

Chris

Read the forum disclaimer.

Almost certainly it's the switch or an intermittent in the wiring leading to the switch.

Not much else left.

You can confirm this by safely bypassing the switch with a short wire or two safety pins or two straight pins, etc. after first turning off the power.

You need to hold the pins together with something that is electrically an insulator. Thick cloth, thick paper, rubber, a dry wooden clothespin.

IMHO leaving a small hole in the wire insulation is not a problem for this application.

The phone company used to use alligator clips with penetrating spear points, but they are long gone.

Could be a faulty transformer for the low votage lights.

Thanks for the responses guys - didn't realise that this was a US board - I am in the UK. Still guess the comments stand. Will check out the switch at the weekend and take it from there. Will probably not try the bypassing manoevure -way too much of an amateur for that!!

Hope it is not the transformer as way outside of my remit.

Cheers for the posts. Any other suggestions gratefully received.

If the lights flicker briefly when the switch is flipped, then it is one of two things. It is either the switch, or it is the thermal cut-out built into some lights or transformers.

Hey guys all fixed. You were right I unscrewed the switch and there was a loose wire.

Thanks for the pointers much appreciated.

Insulation-piercing test clips are still available, for instance from JS Popper.
