    I have a halogen lamp that I have rarely used. I found it was not working so took it to a Hardware store to get the right halogen light bulb thinking it had ‘burned out’ The store clerk noticed that the electrical cord had a melted spot and figured that the wiring was probably damaged. How do I connect the wires after cutting them? I could splice then like twisting them together in a straight line (probably not secure enough if accidentally pulled or I could make loop them together by bending each wire backwards (onto itself), hooking them together, then twisting each wire around itself, then taping wire with electrical tape. There is a 3rd way using electrical connectors which I do not have and cannot buy at this present time. I’m very tempted to do the hooking type, but I’m not sure if doing so will cause overheating of each wire or cause more resistance in each wire. Please help me to figure this out. Thanks in advance for your consideration of this request. I await your answer. Thanks again.

    Hi Kyna,
    The concern that I would have is why there was a melted area of the electrical cord. This may be an indication that the cord is actually not the right size for this light fixture, which could lead me to think that the light fixture may not be safe. As for repairing a cord for a light fixture, I would only reccomend replacing the whole cord with a new one because all electrical splices must be enclosed inside a protective enclosure. Consider taking the light fixture to a light fixture repair shop and have their technician evaluate the situation with special attention to the melted cord. The light socket should be examined to make sure the correct size lamp has been used as well.
    I hope this helps you.
    Be Safe,
