Does copper wire go bad?

^^^^^^^^^^^^^^^^^
All this is is why I have been preaching for years to deaf ears!

Most of our cars are or approaching 50 years old. Replace it. My choice M&H! I drive knowing every strand of wire is new and less likely to start an issue that can lead to total meltdown! No shortcuts or add-ins on original type wiring without without understanding the additional load and possible impacts! I have seen reports of issues with M&H but believe the wrong piece was ordered. These cars differ from year to year slightly, Models, makes and years were all slightly different. Do your research and order the correct piece. I started stripping back my old harnesses just for giggles and was not surprised to see lots of green and black badness. I do not know if the repro stuff will last as long but comfort in believing it may!
