I replaced a halogen security light with a LED version about a year ago. I mirrored the wiring and all went well until a few weeks ago when it kept tripping the fuse board in my garage. I checked it out for water ,tightening the connections while I had it open. The earth from the 3 core input seems to have no where to go and is taped off. Could this be the problem? I could upload a picture if I knew how!
