Thread: Wiring Splicing Tips? Solder vs Butt Connector

That is a very good write up on soldering and that is how you should do it. It takes a lot of practice to be able to solder well. All my solder joints had to go under a microscope before they would be accepted and shipped out so that they can see every imperfection in the solder. That makes for a frustrating time when you are just starting. They are kind of picky when it comes to aircraft harnesses & circuit boards. Crimp connectors do work, they just create some extra resistance so I will just leave it as it is a personal preference sort of thing.

indeed.

I dont know how many times i have seen butt connectors fail when exposed the the elements. If not properly covered they retain water and will corrode quickly causing a bad connection. I will never use one period, if i have to crimp i will always use a crimp cap so that the wires are at least touching each other.

lol once you start talking about busting out the microscope I'm rolling crimp connectors

This is the way I do it.... keeps the elements out... holds the connection together.... If it is done proper you will not make a better connection...IMHO

My personal experience says to use solder whenever possible. I have had butt connectors fail or corrode over time. I don't see how a properly soldered joint is susceptible to vibration forces when a butt connector is just a friction fit connection to a (multi-strand) wire.

I would try solder on a sensor also. I used crimp connectors to make my o2 sensor wire longer to get to the j-pipe. I now have a cel for the sensor. Still runs fine tho.

old post but....

as stated prior, over time with vibration solder brakes and the connection will go to $hit

This owns all.

I have aviation grade butt splices that I use... Better than solder IMO. I worked as an avionics tech in the Marine Corps and at TWA. They require a special crimp tool you can't buy just anywhere though...
