Would smoke in a connection of two wires destroy the whole wire?
I replaced the power pack for my line of low-voltage landscape lamps. Only the first lamp in the line came on. I knew it must be a place between the 2nd and 3rd light where I keep having to redo the connection between 2 wires. Stupidly, I forgot to turn the power pack off and pulled the 2 wires apart, whereupon there was a spark and smoke was produced. The revealed wires were a bit brown, so I cut them back until I could see nice, bright wires under the insulation. I connected them well, but then not even the 1st light would go on anymore. I tested a new light with a new wire before the 1st original lamp, and it worked, making me think I must have destroyed the wire. I then bought a multimeter with not very extensive instructions from a Home Depot guy in order to figure out whether the whole 100-foot wire was really fried, but I could not get it to register anything even by testing a good battery (so it's either bad or I don't know what I'm doing). So I put the new wire back on the power pack, thinking to test it to see if the multimeter works, and now not even that light will go on. It just goes from bad to worse. I need some advice.
Esta é uma boa pergunta?
