I have a set of 6 12v recessed lights in the kitchen. Each light is connected to its own transformer, reducing the voltage from 240v to 12v. My problem is that one of the lights has stopped working. I have replaced the bulb, but it makes no difference. I've checked that the bulb works by putting it in another light socket - and everything works fine. A voltmeter shows that the voltage coming out of the transformer on the light that doesn't work is 17v, whilst the voltage coming out of a transformer on one of the lights that does work is 7v (Assuming I'm using the voltmeter correctly - I'm no expert!). My question is - Is it surprising that 17v is coming out of a transformer which is supposed to reduce it to 12v? Would you expect the bulb to blow if this is the case (because it doesn't)....and would the higher voltage cause the light not to work? Any ideas/advice you can offer would be much appreciated. Cheers
