Years of working in military mobile communications, than countless hours building/maintaining cable systems in civilian life, I have to say your video hit the high points of field splicing. It was accurate and informative for the techniques you demonstrated, good job.

NO ICE....After the repair man had been out twice and not fixed my ice maker I decided to figure it out myself. No Mr. repair man I didn't put the filter in wrong, it was a design defect that the wires broke from opening and closing the door. Your video gives me the confidence to take care of my home and small repair jobs, while saving money.

Great video! I've never replaced any kind of electrical wiring before, but I just replaced a defrost thermostat in my 20-year-old refrigerator. Thanks to this excellent video, I was able to connect the new thermostat's wires to the refrigerator's wires using a red butt connector and electrical tape.

The main takeaways that I learned are:
- what a correct crimp looks like (I practiced on the old part several times before I tried it for real)
- be sure not to strip some of the copper wires (thanks for showing that -- I never would've thought to look)
- pull on each end to ensure that the wires are secured in the connector

I credit this video for helping a first-timer successfully repair her fridge. Thank you!

just one thing to add regarding heat shrink tubing. There are 2 types, adhesive and non-adhesive. The non-adhesive ones are not suitable for high moisture environments. Moisture will actually wick inside the tubing and corrode the wires quite fast. The adhesive type on the other hand is extremely good for preventing corrosion. They also tend to be double walled and have a 3:1 shrink ratio.

Great video. I was taught to melt a little solder onto the soldering iron tip before placing it under the twisted wires. The little molten solder lump greatly increases the conduction of heat from the tip to the joint. With the tip contacting the underside of the joint, the rising heat will rapidly heat the whole joint. Then, add your rosin-core solder to the top. It will melt right into the hot joint almost immediately.

I love this video. You tell us how to do something without fussing about, including mistakes to avoid, and the visuals are nice and crisp. Beautiful work!

Ok so, super gratitude. Feeling clever, might delete later. Headlight socket replacement, in place (tight space) on a 98 Infitniti QX4. After several moments of frustration, this video came through in the clutch. I kept wasting connectors with failed crimps. After watching, I slid a parallel connector onto the car's wire, weaved the wires together ala the solder section, then slid the connector over the wires and crimped with a needle nose pliers adjacent to the wire cutter area which mimics a crimp pretty decent. Electrical tape over the 3 individual wires, then back into the sheath and electrical tape over that. I am please with myself and yall are probably the only people that care LOL. Thank you for reading. I no longer have to pop the hood and jiggle the wire to make my headlight work. PEACE!

Well done. The one thing I'd add is that when working with heavier gauge wires and/or an iron with limited heat output smearing on the rosin can be a big help to help keep things flowing.

I love this!
As a mechanic, it's easy to get stuck in my ways. I was taught this way, this is how I do it. But I forget that maybe there are better ways of doing things. This video proves it.

Crimping tool? Wire stripper? Buddy, I have teeth for a reason.

[edwardbernays]

I’m not even a mechanic or electrical engineer, but watching this video makes me want to splice wires together for the fun of it..🤩

[topgrain]

Glad to see none of those nylon, closed-end crimp connectors featured here. Two wires carrying a high current, joined with those, seems to be what caused the huge recall of those air fryers recently.

Great video, I worked for a company called Raychem 29 years they invented heat shrink tubing as well as soldersleevs and much more .... Great American company . 🇺🇸

[anthonyfarrell]

Don't forget the lineman's splice. Fewer tools needed, but you need to sacrifice more wire as they are tied together. A very strong connection.

[brookhurstdevelopment]

This is the best DIY video for wire connections. Rather than just one approach, the top three are shown in detail with pros and cons.

BEST I HAVE SEEN ON YOU TUBE WITH THE LATEST GOODIE CONNECTORS; GREAT JOB, TYVM - ex Navy Electrician.

[jvilla]

I love how you show what happens when you do the “not to do’s”. Love this video please keep it up!

[mikemarcott]

I also like the way that you talk during the tutorial you're very humble and knowledgeable

[kevincarr]

I loved the style and presentation of this video. It has the feel of an electrical engineer student making a PowerPoint in an early class. It’s simple and explained well. Plus that last connector blew my mind! So

[toheebsalawudeen]

It really went a very far way in helping… even beyond what I initially wanted was learnt…

Thank you so much…
