I guess 12VDC would qualify as low power, but some still draws a lot of
amps. I've had to clean corroded wires many times on vehicles, and
reconnect them. Just recently, there was a melted plug under my dash,
powering the blower motor (for heater). I removed the plug and found the
wires overheated, so I cut off a half inch on each end. That was all I
could spare. Then I soldered them and taped. That plug is a common
problem on my vehicle, and there have been some fires because of it. The
plug was under rated for the current draw.There was a recall for it, but
that expired years ago. The vehicle is a 1995 model. According to what a
mechanic told me, the recall had them remove the plug and crimp the
wires together. I think soldering is a far better splice than crimp
connectors.


If the connection is subject ot viberartion, the crimp , if done correctly,
is beter than soldering. The solder makes it into a solid wire and flexing
will break it over time.
