Re: Crimping versus Soldering
As stranded wire tends to wick water along its full length over time. Letting the solder wick under the insulation, then soaking the end with liquid electrical tape, seals the end much better. That is why I prefer solid single strand wire, below decks ,which I have had zero problem with over the last 28 years. Most stranded wire I've pulled out of boats was corroded and turned black over its entire length. One guy on another site said his solid wire is in perfect condition after 45 years, something I've never seen stranded wire do.
Solid wire has problems outside, when the insulation and vibration break it down. Black insulation is far more UV resistant.
