I agree. The crimp is for a solid mechanical connection. The solder
gives a good electrical connection and resists corrosion.

wrong. solder connections fail under high load conditions.

CRIMP for current, solder for corrosion resistence. In that order.

Would you mind explaining exactly how a solder connection fails "under high
load conditions" If a wire gets hot enough to melt solder then that circuit
is greatly overloaded and the fuse should have failed long before reaching
that point.

when the connection is soldered it lacks mechanical integrity. solder is soft
and any chance of movement -- any, even walking on a floor near the equipment
in a building -- loosens the connection until it eventualy fails. Even if
after soldering the connection is clamped TIGHTLY with a mechanical clamp it
eventually fails.

If the connection is FIRST clamped TIGHTLY mechanically and _then_ soldered for
corrosion protection all if right and holy.

I refuse to get into useless debates based on absolutely ridicules
assertions...so I'm going to stop right here and avoid the name calling that
usually comes next. But I can give many examples that will prove the
statement below completely unfounded. I solder all of the wires on trailers
that I build (and I build a lot of them) and they are subjected to lots of
movement and vibration and never fail. Sometimes the wires will get pulled
apart but not the soldered joint. Huge numbers of soldered electronic
equipment in high vibration service routinely last a lifetime without
failure. The mechanical connection is far more likely to loosen, that's why
we have loctite and NyLocks. Anyway, my participation in this thread is
ended. It is obvious that Jax is more interested in "winning arguments"
than in meaningful posts and in reading some of his past posts, name calling
is next.

so, you are a hill-billy idiot.

If the connection is crimped first, you have it correct. Additional
soldering will create the stress concentration, which can fail slowly
through minute cracks creating a resistive connection, which allows more and
more circuit voltage to drop accross the joint. This heats the joint, and
creates enbrittlement of the joint and wire and so on. This is not rocket
science folks. It is common sense.

Tom, you are incorrect. A solder joint under vibration can easily create a
resistive connection and it can be undetectable until it overheats. Please
review my previous advice and use a crimping tool that creats a very high
pressure crimp.
