When I do bullet connectors, I use the solid brass ones, and, after applying the proper hexagonal crimp, wick in solder through the hole in the end. The solder insures a good connection, while the crimp provides strain relief.
Delco/Packard Electric require soldering of connectors for field repairs, rather than just a crimp. Even using the proper ratchet style crimpers on my Weatherpack terminals, I still solder them. However, the Weatherpacks have built in strain relief, so I think it's a non-issue in this case.
I've never had a connector failure yet.
I think the ability to <u>properly</u> do a solder joint may have some bearing here. /bcforum/images/%%GRAEMLIN_URL%%/grin.gif
