I'm new to posting on the forum, although I have used it for reference for several previous DIY projects. It the moment I have an electrical problem that is puzzling me.
Our first floor landing has 2 low voltage halogen spotlights. Although both have worked in the past, one of them has not worked for some time. I've checked the bulb- that is not the problem.
Today I bought a new transformer (12v, max 50W) and fitted it, reusing the old bulb holder as none was supplied with the new transformer. With it fitted, the fuse constantly tripped. I refitted the old transformer and the bulb did not work but the fuse did not trip.
I assume that if the fuse tripped there is no problem with the power to the main lighting ring (and because the other light works). Do you have any suggestions or tests that I could do to get to the bottom of the problem? Could it be the bulb-holder? If so, why does one transformer trip and the other not?
I'd welcome any advice. I'm hoping it's something straightforward that I've overlooked!
