Wiring 101: Why 50% of All Crimp Connections Fail – Does Up or Down Matter? Let Us Explain


Wiring 101: Why 50% of All Crimp Connections Fail – Does Up or Down Matter? Let Us Explain

Sometimes I see tech videos online and wonder how something so simple needs a video, and then I realize how many times I look something up on YouTube only to find that the solution is as simple as it gets. So it happens to all of us. With automotive wiring there are always different thoughts on crimping vs soldering and what kinds of connections and connectors are best. In new vehicles there are almost no soldered connections anymore. Soldered connections should be rigid connections, like a circuit board or something, not a connection that might experience some flex or vibration, as the solder can crack. So crimp connectors are the right choice for most wiring situations in a car or truck. But these simple connectors are often a source of failure and there are a couple of reasons why.

First off, make sure you have a good pair of crimpers. That doesn’t mean expensive, as one of the pairs being used in this video is a manual crimper that costs around $10. The other is a ratcheting setup that can be bought in a kit for around $30, or as a stand alone for around $20. Again, not expensive, so get a good one you are comfortable with and then learn to use it. And learning to use it is what this video is all about.

If you have never actually paid attention to crimp connectors, there is a right way to put them into your pliers and a wrong way. The right way will make a very strong and secure connection that should last a lifetime. The wrong way will cause you issues as the connection will not be secure or electrically sound, both of which are bad.

So watch, learn, and let us know what you think.

Video Description:

Crimped connections can suck for one reason that most DIY’rs have no idea bout. Should the connector seam should be UP or DOWN? How do I know wat size wire to use? Are manual tools really stronger? End the Crimp anxiety when you pull that wire and learn to crimp like electric Connectors, Insulated & Non-Insulated like a pro.
