As an electrician (Sparky), I've had my fair share of rushed/bad crimps. I always hate accidentally cutting the copper wire. It is so annoying. I love watching you do electrical work. Reminds me of why I got into it

[@chrisfix]

Thanks a lot! Yea cutting too deep into the copper wires by accident is always so annoying. You try to be careful and you still cut a few strands haha

[@rylanhuntley6867]

@@chrisfix Stripping tiny and thin stranded wire such as Diesel Locomotive Cable I’ve found that when you cut all the way in the insulation you score strands no matter what then they bend and break. I’ve found the best way to not score the copper is to instead score the insulation and bend it until it the insulation breaks and slides off.

[@cliffadams84]

Electrician here! Great job as always Chris but I have one critique. When crimping lugs it's best practice to crimp at the top of the lug not the base like you did. Starting at the base leaves to potential of a air gap between the top of the lug and the wire. This happens due the to stretching of the lug when you crimp it. Now I'm 100 percent certain you won't have any problems with the way you did it because it's such low voltage but just thought you should know. As always Great job and love your veidos.

[@chrisfix]

Thanks for the tip!

[@Neilledra]

​@@chrisfix To not have to pay attention to what Cliff says, you can buy terminals with a little hole in the front, as i do ^^ And you can find adhesive heat shrink, with a layer of glue inside of it, so it melt when you heat the shrink, ang glue it to the cable, so you dont have to use silicon, and avoid greasy fingers haha! Of course theses two tips cost you a little more money, but can save you some time if you have a lot of crimp to do!

[@bustanut3888]

@@chrisfix another piece of advice, you could always leave power on the ECM/PCM.. So that way your engine wouldn't have to relearn all the sensors the first 30 mins of driving. And in some states this will cause people who use this daily to fail vehicle inspection due to incomplete drive cycles.

[@potaatti]

@@Neilledra The lug also stretches during crimping, so you still have to crimp it starting from the top of the lug. If it is done the wrong way, the lug will not be able to stretch and it may crack.

[@thecomputerguy777]

@@bustanut3888 that’s what I was thinking. Kill the spark system and not the DME/ECU as it’s a BMW and the electrical systems in it are not a fan of sudden power cuts and comebacks. He’ll be on the track and having to spend a few laps relearning everything before his car will perform like it should as it’ll have to relearn shifting, and sensor/engine adaptations.

[@AgentOrange96]

Seeing the inside of the crimp is so cool! I've been doing automotive work my entire life and have a degree in electrical engineering. But I had absolutely no clue that a crimp like this compresses all the wires into a literal solid lump of copper! That makes me feel a lot more confident in how they work. That's crazy!

[@fraire711]

Yeah that’s what surprised me the most. I always thought the wires would just bunch up next to each other.

[@Leuel48Fan]

I still don't understand the physics of how that happens... there's no heat involved and they're still solid strands, how exactly do they "liquify" and melt into solid core from just compression?

I actually just installed a battery killswitch in my grandma’s lawnmower 2 days ago, as an alternative to manually disconnecting the battery to prevent it from dying, & I feel proud of it. Also for anyone looking for advice on putting a killswitch in a lawnmower, basically what I did was this: -Leave the ground wire alone -Run a new cable from the positive battery terminal to one side of the switch -Take the original positive battery cable that goes to your starter, and connect the other end to the other side of the switch. Essentially, what you’ll be doing is putting the switch in the middle of the positive side of the circuit.

[@denryaron6238]

Proper stuff. Only concern I saw here was with the relay "trigger wire". I have met relays that have had their contacts getting stuck together. Therefore, I would have run the switched wired through the killswitch to protect from a relay getting stuck in the "on" position.

[@sensiblewheels]

Very interesting!

[@milk-it]

That makes sense. Relays aren't perfect.

[@chrisfix]

Thanks a great point, although very rare, technically a relay can get stuck in the closed position and not shut off, even with the trigger wire cut off

Always account for those things that "never happen," because they can cause a lot of trouble when they do.

For the crimp heat shrink, use adhesive lined shrink tubing. It has adhesive inside that when heated and shrunk will fill the gaps and perform the same function as the silicone paste with the added benefit of waterproofing the connection.

[@panuvasungsopapong2891]

You are an excellent mechanic both in theory and in practice. I really like it. Thank you for a great presentation with clear pronunciation and technical terminology used. I will follow you forever.

[@ncc74656m]

You can also use a heatshrink that shrinks more than standard, which is typically 2:1. There is 3:1 and 4:1 as well. It's good for fixing those oopsies where you forgot a connector, or practicality makes it difficult to use standard heatshrink. I also recommend using a glue filled heatshrink on any connection that risks exposure to weather. Another note - buy quality connectors/terminals from reputable sellers. Lots of cheap ones these days are just copper coated aluminum which lack the ability to carry the rated power.

Great video as always I've learned a ton of fixes and generic info from your vids over the years. The only thing in this one for me is the file. When you use it you should only use forward strokes, lifting off as you come back to start the next stroke. Your file cuts cleaner and lasts longer and will probably clean up the edges faster.

[@chrisfix]

Thanks for the tip but that’s actually a myth that was disproven recently (at least the file wearing down). They tested it out and there is no significant difference between lifting and scraping on the back stroke. I use to think the same thing! You can search for the video of the test on KZbin.

You can also 20:38 use small colored zip ties spaced every 12 inches or so as an indicator. They come in about 8 - 10 different colors. Bundling wires for like you are, you could put yellow ties on the alternator side of the switch and red ties on the battery side. That way at a glance you know which red cable is runs where.

Some heatshrink tubing comes with an adhesive already pre-installed on the inside. When you put it on, and then heat it up, it will melt the adhesive - and then dry when cooled, creating a waterproof seal.

[@Hoochimama]

Happy Father’s Day Chris, you taught me more than my Dad ever did!

[@mannys9130]

My biggest concern with this being used on a regular basis, like a DD with a parasitic draw, is the constant erasure of ECU's volatile memory. It'll need to run a monitor test and relearn everything for every system, every single time. It won't know what the last state of all the systems were, and any code that isn't a 1 trip code will never ever get to request a CEL. It will be risky with each power cycle. My mother's 2008 Dodge Dakota had the ECU totally die when the battery got weak and was removed for replacement. We disconnected the battery, put the new one in, reconnected it, and the engine immediately ran horribly. It was running ridiculously rich to the point that the cat was overheating and smelled like rotten eggs. I shut it right off at that point and said "Wow this is incredible. Power cycled and now it's completely lost fuel trimming capability and it's torching the cat. Fantastic. Classic Dodge electrical problems." It was literally running fine when parked, swapped the battery, and it ran terribly at first start 10 minutes later. Troubleshooting pointed to the ECU and a new one fixed the issue so that was beyond a doubt the issue. You run the risk of a problem like this when power cycling components meant to be powered on 24/7. The ECU dislikes having to relearn data. So, I'd suggest only doing something like this for the racecar and/or a winter and summer DD that sits for a long period of time on the off season. You can disconnect the battery and connect the trickle maintainer onto the posts directly. Easy. 👍

[@Stylemaster911]

Interesting. I've used plenty of military vehs, including with complex ECUs (Mercedes G Wagon GD270CDI) for example, which have a battery master. Besides the clock never working, I have never seen that be an issue. Would there be some kind of solution for vehicles with this feature from the factory to prevent ECU issues?

[@JimGriffOne]

Protip for those wanting to prevent car theft by using one of these: You can install a kill switch and put a low amperage fuse (5 amp) in parallel. This will cause the fuse to blow if someone tries to start the car without the switch installed. The fuse is there to keep current flowing to components so you don't lose presets on your radio and/or don't reset any computers, but it's low enough amperage that it'll blow when the starter is used. You're welcome. :)

Pro-pro tip: If you do that keep a spare fuse somewhere in your car. Because you most definitely at some point will forget to turn on the switch before starting the car and blow the fuse.

[@KuntalGhosh]

Better use a resistor or heating element..

[@knightking69]

won't the computer and radio get reset if the fuse blows though? 🤔🤔🤔

[@Jehty_]

@@knightking69 well, the question is if you would rather have to reset your settings or buy a new car because the old one was stolen 🤷🏼‍♀️

[@JimGriffOne]

@@knightking69 Only if you try to start the car without the switch installed, or someone else tries to steal it.

I don't have a car or anything, but ever since I was younger, I wanted to install a hidden kill switch in my car. This video wasn't perfectly on what I wanted, so I will watch your other hidden kill switch video. But thank you for making this video, it is extremely informative and wildly entertaining. I thoroughly enjoyed watching it. Great job!

[@CrazyPlayer-pf2hv]

4:30 Its common practice to prefer to switch the positive terminal over the negative. Also in working with electricity that is the case, you always want to switch the "hot" cable

I definitely love ryobi products. It’s way cheaper than brands like Dewalt and it’s more reliable than brands like Milwaukee. I work as an electrician and when I started we had 3 drills on the job trying to do our rough in all 3 of the chucks stripped out because of poor design I went go grab my ryobi drill and did the whole house with 1 drill

[@chrisfix]

Their old stuff was eh but I wanted a less expensive alternative to the Milwaukee stuff and I got a few of their new 18v lithium tools and man what a difference! I ended up getting their lawn stuff too and the chainsaw is crazy good!

[@dustinbergeron7508]

@@chrisfix completely agree with you keep up the good work love your videos

[@Jehty_]

Strange that you think that Ryobi is better than Milwaukee since they are both owned by the same company and as far as I know even manufactured in the same factory.

[@Zadnak1]

@@Jehty_ It's all about brand perception. Also, I hate marketing.

[@Jehty_]

@@PierceGomez let me quote them: "more reliable than brands like Milwaukee" I don't know about you but me personally if something is more reliable then I call it better.

[@antiwokehuman]

Damn. I didn't even notice it was 40 mins long. This is literally the gold standard for this sort of long informative content

[@TehBIGrat]

Great as always and I can't "fault" your advise at all. I will however add that a soldered connection to the resistor leads would be far superior. Those type of crimp connectors are not recommended for use on solid core wires (ie resistor leads)

[@FireStriker_]

I was wondering my self if soldering would be better for that

[@bigzay0506]

Hey Chris I have been watching your videos for a few years so when I get my own car I can fix it so thank you these are really cool.

[@chrisfix]

The is for all the support and I’m glad you’re learning a lot!

[@jordanjo2071]

This video is gonna be handy for our race car project, thx Chris!

[@BreckenDarby]

I just bought my first truck, it’s a 78 datsun 620 but it has major rust issues do you have any big tips on restoration or replacement?

[@ItsZel]

Chris has a video or two regarding fixing rust holes, rusty panels and such. You might want to check those out too ^^

[@nicholascox7947]

He did it on a honda del sol however its basically the same for any floor panel and such

[@tylerglidden775]

Linex it but gdt the first coats professionally done

[@darkru8913]

check the frame for rust, if there are major damage ( large holes etc.) then it is unsafe for driving . You hopefully already checked this prior to purchase but wanted to let you know just in case,

Battery kill switch is SUPER DUPER USEFUL for a car thanks on showing us how to install one 😃

[@mikenormandy9250]

Being an electrician this was VERY WELL EXPLAINED! Nicely done, Chris! - I am just shocked, with how well you do your work, you don't twist the zip tie's slack with linesman's pliers and just cut them with dikes! LOL

[@helmermussell7072]

You definitely get a tighter bight with twisting off the tail but I think there's enough tightness on the cable without twisting off the tail.

[@willoneil1970]

can you wire manage my PC? 😂

[@ColombianLNP]

I will probably never do 80% of the stuff Chris does . But honestly his videos are so engaging that i can't help but watch and support !!! Cheers from Colombia amigo!
