You may find this article valuable in locating wires and troubleshooting problems because the fundamental strategy in finding and fixing electrical problems is to find a place where there is no problem and then keep splitting the distance between that point and the problem point.
When working with an electrical problem, increase your safety by taking simple precautions. Turn off the breakers to any zone in which you are functioning. Make use of an outlet tester to confirm that the power is really off before touching any cables. Electrical repairs are more fun during the daytime. Trying to squeeze in an electrical repair in the late afternoon or evening can make for a long night of juggling flashlights, extension cables, ladders and tools. Waiting eighteen hrs to start the next morning is in all probability the best suggestion.
When fitting a switch, make sure it is on the proper conductor. You don’t want to be fitting a light fixture with a switch on the neutral wire. If you are lucky, when you turn the breaker on, all that transpires is that it will trip and scare you. Replacing existing components is generally straightforward enough but, place things back the way you found them and you should be ok. On the other hand, adding new equipment can be a more difficult task to take on. Be exceptionally careful with any wires that are not white, grey or green. In one home that I worked in, some very strange electrical work (probably not done by an electrician). I had this nasty shock of locating cut (but not capped) black and red wires. I think they were probably intended for a hot tub installation. I carried out a quick test on them only to find out that they were indeed live giving out 220 volts. Frightening to say the least!
I have always had all of the properties that I own maintained by the same company, they go by the name of Electrician London. Over the years they have saved me plenty of money, just by giving me some very useful advise and help.
