[QUOTE="keep_hope_alive, post: 7470717, member: 576029"] you mean after 50+ years? i'm not sure that is applicable. [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] there are electronics from the 30's and 40's that have solder joints that are just fine. i agree that poorly done solder joints aren't desirable. as has been mentioned, solder is intended to reduce resistance between wire and connector. solder is not meant to be a method of mechanical fastening nor is it intended to withstand strain. that is why you should always secure your wire independent of your connection. i rarely see this done, and only in competition vehicles who follow the installation rules. most people just rely on the ring terminal to hold the wire - which is poor form. crimping alone puts stress on the wire strands and some are damaged in the process. additionally, only the outer strands have contact with the connector, the inner strands have more resistance to the connector. lastly, crimp connections are subject to oxidation, which further increases resistance. without solder, a crimp connection increases in resistance over time. i've also seen many crimp connections pull off over time. crimp then solder then heat shrink is the most reliable and least resistance connection method. period.
