not bad, except the sequence in "crimp, tin, solder"

Sounds like good info for all. Personally, I'm a believer in "tin - crimp -
solder".
When maintence boss for a fleet of seasonal boats, I had one person who
would
go to each boat and check EACH electrical connection for corrosion and
tightness.
At first he considered this a waste of time .... then he began to run across
loose and corroded connection .....

G As I said, I prefer "tin - crimp - solder".
Always felt we got a much better continuous bond between all the parts this
way.
To each his/her own .... and I never had a problem with these connections in
the time I remained there..... our biggest problem was things loosening up
(screws and nuts).

Not sure how one would tin the wire or the connector once
the crimp has been made. Proper wire is already tinned and
so are many connectors. I remember reading many years ago in
NASA Tech Briefs that crimpped connections are more
reliable than soldered ones in the long run due to microcracks
in the solder joint due to thermal cycling.

Same here G but I didn't want to bite...
I've since learned that the method I describe is not always considered the
best, but we were working with old and new wiring systems, and this seemed to
hold up for extended periods of time which was an obvious plus.
