The experts say no because the solder creates a "hard spot" which can
work harden and break after repeated vibration, same as using solid
copper wire instead of stranded. * There is nothing wrong with a good
crimped connection if it is made properly and kept dry. *One of the
secrets to keeping it dry are to always install them with the wire
pointed downward, and/or have a drip loop within an inch or two of the
connector.

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.

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.

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.

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.
