Hi everyone, I'm new to the list and know very little about building but I
have something to add here.  The solder in these type of connections, being
nice and soft tends to migrate over time and with vibration.  This can cause
pre-soldered connections to come loose at the most inoportune moments and
suffer greatly from thermal damage.  I prefer to hard crimp a lug onto my
cable ends and then solder that in place if I want extra security.  Thanks
for your patience.
