Oh, I do understand that, but i understand what I do. And what I do seems to work well for me. then again, What i do on wiring, isn't really a strategic process, but *in some cases, the ' keeping dry' is. * I've had wire crimped well into a connector and with a matter of simple humidity, still corrode over rime making the connection useless. I do understand the 'hard spot' theory, but I also understand anchoring the wire is important as well. ?;^ D The primary consideration is a strong mechanical connection (crimp). Soldering has limited value except in high current situations. The best corrosion prevention starts with tinned wire. followed by waterproofing the connection. Leece Neville rectifiers have had crimped and soldered connections for 50 years. on the 70a. up to the 200a. 12v. .units. http://store.alternatorparts.com/ima...tail/11912.jpg I've never seen a soldered connection in the end of the wire go bad. I've seen diodes blow up and insulation burnt clean down to the bone, but never a bad connection on the rings Same way with the ones used on that big block 320a. unit that Wayne is presently using. http://store.alternatorparts.com/ima...tail/11913.jpg However it was found that the diodes in the 225 to 320 a. units didn't have enough strength for reliability for the demanding loads that the unit was designed for. . With improved design and manufacturing techniques, the status is to use diodes that don't use leads but rather, are welded to copper bars in a rigid assembly which tends to be a superior update. http://i.ebayimg.com/t/Leece-Neville-4800-4900-Alternator-Positive-Rectifier-/00/s/NzY4WDEwMjQ=/$T2eC16NHJG8E9nyfmYkKBQbwRE%29pO!~~60_35.JPG |
