Totally agree with the desire for the perfect layout, but just committing to a layout do you can start. I figured for sure I’d thought of most things, but then sure enough I always wish I had moved something afterwards 😅 - love the plastic mounting plate. Seems much easier than the vinyl coated plywood I normal try mount stuff too. 12v circuits are so dang fun to wire. It’s comforting how straightforward it is once I wrapped my head around wire size for desired load. The big bummer is the quality difference of the different connectors available on Amazon. Some of them are amazing, others just complete suck. The adhesive lined ones are my personal favourite along as they come with the proper metal thickness for the wire size they are meant for. Looks like that’s the kind you got for most of your end connectors good stuff man! You’re doing this build so incredibly thorough. Unfortunately so many Amazon sellers just cheap out massively on connectors and that really starts to show with 12awg circuits. Those terminal buss bars as connecting areas look so dang helpful. I so wish that I had used those on my van build. What a great way to terminate circuit wiring and allow it to easily be modified with cable cutting. I love the level of breakdown you are doing for this series. Probably took so much effort to keep it concise. Not to long and not too much details, but totally info I wish I’d seen in this format 5 years ago. Love it!

[@FrederSnorlax]

this is very good advice - Perfect is the enemy of Good Enough! But to go with that, there is something called "Second System Effect" - the second version of something you build, you want to add all the little things you thought of the first time around, and it turns into an overcomplicated mess (with a lot of features you (or your customers!) never use but have huge hidden cost)

[@FrederSnorlax]

hey Jack. The skin effect - where the electric current primarily runs near the surface, only applies to high frequency. for DC applications it isn't really a concern. Flexibility with stranded wire is essential for chassis wiring applications though.

i was gonna say the same thing

[@thomasmwangi8136]

I could watch this series forever. This is a proper Netflix doc.

[@TheHookUp]

Great video! I'm not sure that bit about stranded vs solid wire is correct though. In all applications the amount of current that can run through the same gauge of stranded wire is less than an equal gauge of solid wire. This is because the packing density of a cylinder isn't 100% efficient and therefore there are more air gaps in a stranded wire of the same thickness. I think what you were getting at was the "skin" effect of thin wires. The greater the surface area, the more "skin" area it has, this skin is where current dissipation happens (which is one of the main causes of "voltage drop"). Stranded wire is definitely best for your application, but solid wire is much better at carrying large current.

[@ebrahimhosseini1685]

Skin effect actually kicks in only in higher frequencies. 👍🏻

[@qweqweqwer696]

it's about the stifness, simply it would be hard to bend a solid cable of this diameter

[@carson5879]

While it's true that wire stranding is the best way to reduce skin effect, it's an essentially moot point here because skin effect is only present in AC electrical systems where current flows in both directions in a sinusoidal waveform. This pushes the vectors of functional current to the outside of the wires. While electric motors do create an electromagnetic field (it is in fact the very principle upon which they work), it does not interact with DC current in quite the same way and any variable waveforms are minor and happen in very small segments of the conductors. DC power can be utilized in any number of waveforms, especially with modern digital capacitative devices. DC to AC inverters work this way, providing opposing charges, stepped up to AC equivalent voltages, ramped up and down at the appropriate frequency to mimic the current created by an electromagnetic generator. Standard DC current, however, is applied at a constant voltage when coming from sources like a battery. The important thing is to ensure that the conductors will not be at risk of being damaged, which flexibility is good for. Additionally, because of the higher 480 volt system, much smaller cable can be used to supply the power because current (Amps) and voltage are inversely proportional in reference to conductor resistance (per Ohm's law) which causes power loss to heat and degrades insulation, and they are directly proportional to power (watts), meaning that higher voltage with lower amperage can supply the same functional power with smaller conductors as lower voltage with higher amperage.

[@KeithZim]

The longer the wire the more resistance it will have. Speaker wires for instance need to be the same length to be the same volume. Resistance also creates heat. The longer the wire the more resistance you have which creates more heat. More heat creates more resistance in the copper wire, leading to more heat leading to more resistance and this cycle leads to melt downs.

Zack, It doesn't look like you have any fuse protection for the individual relays. If you had a fault with the loads of the relays, other than the far right one, your only protection is your 100 Amp circuit breaker which far exceeds the capacity of the relays and wires on the relays. And could set your passenger on fire :O You may already have done this with added fuse block shown at the very end of the video. The red/orange power wires on the relays should each go to their own fuse of 30A or so and not to the red bus bar. With that said, for learning as you go, you're doing a great job & neat work. I love your channels.

I would recommend measuring the resistance of the wiring before and after those solder-heatshrink connections. Those add a lot of resistance to the circuit. That is why crimping is recommended. Besides that, the build is looking cool.

[@treypelfrey2624]

Amen i would never trust those unless you slide it over one wire then twist wire strands together first before sliding sleeve over and applying heat.

Exactly what I thought. Usually when wiring something in car you want to crimp the connections instead of soldering because vibrations from driving can crack the solder. Crimping and wiring is also acceptable

[@sandyleask92]

They do add a noticable resistance and I wouldn't use them for long high current loads. That solder softens easy and they fail with vibrations in combo. I use them for the excellent water resistance, especially in marine applications and I often add a second layer of heatshrink on top. Tip is heat the ends of the connectors. let them cool. then heat the inner solder part.

[@licencetoswill]

the resistance of solder splices is neglible (or effectively zero) if the splices are done correctly. They are fully rated for aeronautical and aerospace use, I was suprised to learn.

[@roughready]

Yeah those connector suck but crimping is horrible as well solder whenever possible crimping add huge issues if you can solder never crimp it's not worth the headache down the road

[@AlecKristi]

Zack, you may want to fuse the wires going to the relays! You only have that protected by the 100A breaker, which leaves plenty of angry pixies to melt wires! Also, I can't believe no one mentioned that in the comments yet (at least I can't find any mention of it), everyone is focused on skin effect ;)

[@twilliamson3]

Came here to make the same comment. The wire should be able to handle the amount of current between the battery and the fuse without melting. ie that 12awg wire between the buss bar and the relay should be fused around 30 amps.

[@droyce4596]

@@twilliamson3 great point. Another thing to point out is that thermal circuit breakers are not great, especially if you want it to work in various ambient temperature. The required current to trip the breaker can range by -30% to +60% or more of the rated value depending on the overall temp range it needs to exist in. However, since he's not running a single device off the breaker, it is really only protecting the wire from breaker to battery, and as long as that wire is large enough to supply near double the breaker's rated current, then it will be able to do it's job just fine. However, the breaker is still more expensive than using a fuse. I usually recommend fuses over thermal breakers for this and other reasons. On the flip side, if the breaker were mounted in a very warm place, it might only need 18 or 20 amps to trip a 30A rated breaker, which leads to nuisance trips

[@TraceyAllen]

I was going to mention that switch your ground side of the circuits and have constant power to them will be nicer to any accessories that have integrated circuits. This exactly how ECM’S are switched inside. They switch ground drivers on and off.

[@stefan52010]

I saw the same thing, and did mention it in the comments. The wires from the power bar can be connected to the right fuse block (constant voltage) with fuses suited for the connected load.

[@mission772]

The relays are protect from the load and 95% of the circuit, by going through the fuse panel. The only thing unprotected is the short wires going from the main feed to the relay(still protected by the 100amp total draw). This is completely fine. In order to melt the wires you would need to a short to ground condition on the relay feed wire. This is highly unlikely and can be controlled by careful routing and securing the wires. This is common practice in the automotive industry. You can't 100% protect everything. You can only protect the 95% of the circuit. To put it another way, say he has fuses protecting each relay. He will then still have unprotected wires feeding each fuse for each relay. Until you get infinite regression.

[@Laurelinad]

13:45 yes. a relais is just an electrically switched switch ^^ so the switching action usually done by a person now is done by electrons so the humanly actuated switch can now be located in a safer and/or more convenient place

Stranded wires have a higher resistance than their solid counter part, given that they have the same guage. Standed wires are used over solid wires when the application is where there is vibration. Solid wires are used over stranded when the application is where there is a great potential for corrosion. Electricity runs through the copper not only on its outside.

[@quintenluyten6382]

The skin effect only affects higher frequency cables: at DC, current indeed runs through the entire conductor, so the argument mentioned in the video was indeed incorrect. It's a fair mistake to make though, since the power grid (running at 50-60Hz) does need to take the skin effect into account

[@foxriderzero]

@@quintenluyten6382 he mentioned invertor at one point so AC is indeed included

[@Bovi527]

When you say that electricity only runs through the outside of each strand of wire, you're referring to the skin effect. This only applies to high-frequency AC though. Low-frequency AC and DC will in fact use the entire 'body' of the strand. Large cables are generally stranded so that they remain flexible.

Things like radios, remote starts, new infotainment systems, headrest displays, heated and vented or even air-conditioned seats, the possibilities are now endless with aftermarket auto equipment within the last decade. I have years of experience, but I just want to say, you have made one of my most complicated things to learn about the trade I used to work, make sense to everybody. I've tried for years to explain to people how relays work but I always seem to wind up losing people through my explanations. Seriously. One of the easiest to understand in layman's terms, on how a relay works I've ever heard. I applaud your effort. Plus, I mean you'd prob do it yourself anyway, but if I was in your area (I currently live in Northern NJ in Bergen County less then 10 miles from manhattan) I'd do any of the aftermarket upgrades you'd want to your truck, but in your case, if you have any questions for me I will be glad to answer them for you. But so far you seem to have all the info and knowledge you need. It took me about 2 months to master that trade. I now work as a residential, commercial and industrial electrician working with 110, 220, 440, 600.... ect voltage systems either single phase or 3 phase power systems (just the difference in voltage the equipment is working with. Standard household is using single phase DUAL 110v leads and a neutral/ground. Where as three phase has a 4 wire setup with 3 wires that run at two of the different voltages I've named above, as well as a neutral).

Me to elon : Yes i don’t have any engineering degree or anything but I’ve watched the whole hummer playlist *YOU’RE HIRED*

[@johnmichaelcordero1688]

That wiring part is so satisfying. I want more!!!

[@kridcsr1341]

this is actually progressing faster than I thought. i'm excited to finally see the e-humvee run through a pile of civics and down across the river. Make sure those holes you drilled are waterproof :)

[@laksh_ayy]

I'd rewatch the whole thing even as a 3 hour movie.

[@nader159900]

This is one of those videos that you don't want to blink while watching! Very entertaining and interesting information. Some might learn more engineering basics from your 25 min video than a 50min lecture All the best Jerry 👍

*The best build series on KZbin* very excited to see it finished, this is definitely gonna be a banger!!🔥🔥 keep going bro.

[@Johan1272]

This series has been amazing. I can tell how much time you spent researching. Your attention to detail and doing things properly the first time is amazing.

[@thejastp120]

First go for it later modify later to make it better

[@BasicShapes]

Whether this fails or succeeds, it's going to be _absolutely amazing._

[@ARPANKUMAR007]

i work on my car and its ecu so i know these things but never could make any non enthusiast understand this ......BUT YOUR WAY .. ITS SO EASY THAT ANYBODY CAN UNDERSTAND..................WAITING FOR THE HUMMER TO GET COMPLETED ...love your content .. good luck.

[@EDP667]

Every week I just sit there… waiting for a new episode of this series

[@TheJaredC01]

That floor mat definitely had deeper grooves from that razer at a level 7.

[@alainkanaan9183]

its amazing how intelligent you are and how you can explain all that stuff and making it simple

[@driftyprince]

i CANNOT wait for this project to cruise on the road completely silent!

[@kristapssavnors3031]

I never expected to be so interested in this series, you are doing a great job explaining everything.

[@jorgenjohnson2168]

I loved this video also. I already saw the last video where you hooked up the batteries but I loved it so much I am now going back and watching the rest of your series. You also earned my immediate subscription and bell ringing which most channels don't get from me until the third awesome video.

[@hf7188]

I would love to see uncle Rich rebuilds input on this build, and since you both are for right to repair, could also be a interesting discussion about of state of affairs as they are now with consumer electronics.

[@rkan2]

He has a Hummer and a Tesla so he would agree lol

[@likebot.]

0000 to push some major pixies, eh Zack? Hello fellow AvE fan.

[@SRiddle]

I know all this.... I am an electrician/engineer... That being said.. I love this episode best, by far! There are plenty of guys on youtube that do videos like this but your explanations were perfect, not too complex, and informative! let's see more of this. I thoroughly enjoyed it.

[@jrmusan]

I can't wait to see this thing all together!

[@knowthyself8233]

This project is so satisfying 🔥 I can't wait for the final result.

[@bryannalimurong5641]

Love that you used those shrinkable wire splices although you need to heat them to the point that the metal solder melts and really fuses with the wire. It's not good until it's solid.

[@bryannalimurong5641]

Atleast that's how we do it in aviation electronics.

[@salehdinkhah6854]

2:48 That's called skin effect and it appears in AC and variable DC, a great build project Jerry waiting for the results!

[@1998raphael]

searched for this comment

[@danielt6810]

I was thought solid wire is better then stranded but makes the cable stiff (good if the cable does not need to move anymore)

[@greglawson9729]

Jerry love the videos. The Hummer is Aluminum you may have issues with using the frame as a ground (common issue with them).

[@alexmawdsley]

The frame is steel I believe

[@t6uav]

Good work. Only suggstion would be to use captive nuts or rivnuts for mounting the relays, so you dont have to pull the panel off to replace relays when they inevitably fail!

[@arnavparashar7]

Very excited for the finished version!! LOVE THIS SERIES!!!

[@TheMechMan]

This has got to be my favorite thing you've done so far. Can't wait to see it finished!

[@tarlspeakman3382]

Been watching. Kind of want to say thank you. I'm an extreme brain and body trauma patient so I have trouble processing stuff sometimes. I watch videos to try to educate myself and reteach myself and a lot of them don't explain or do steps through stuff they just talk that fancy talk and don't explain it. You on the other hand should be a teacher the way you explain the steps and the process behind those steps is educational and I appreciate that. thank you

[@Zakush]

this "electric conversion arc" is getting pretty intersting

[@yashastarikere9920]

And confusing

[@misfitskater57]

Hey Jerry lomg time viewer also professional HD mechanic. I would suggest getting some rivnuts to secure those relays. The last thing you'd want to deal with it pulling that panel to swap a relay out. Had plenty of those fail over the years

[@droyce4596]

That's a really good suggestion

[@RobertSavello]

I just did something very similar in my Xterra. Mounted a LED Lightbar and planned for future upgrades. it was fun figuring out all the wiring and stuff. I built mine almost the same as you, but i used cheap cutting board from Target instead of ABS plastic. because i'm impatient and didn't want to wait for shipping. Glad I'm watching this video, it's showing me that i did it right. Thanks man.

[@johnnyxp64]

loving the series! and your camera angles and stability and focus is amazing! just one question: why dont you clean it a bit more in places like the 12v battery box? 19:09

Hey, I see your random KZbin shorts

[@FavoriteTechX]

@@krystlcrtz but currently he uploaded only about Hummer 🙁

[@memesexpress3786]

I was waiting for this badly.. And still looking forward for more electric hummer build vids...

[@bhatkrishnakishor]

Your explanation for the use case of relays was awesome.

[@Torbox1]

CAREFULL!!!! Your high side power wires for the relays should all be individually fused. As you have it wired now if anything on those relays short circuited there is no fuse and only the high power breaker as protection meaning the short would go up to 100Amps before the relay tripped which would definitely fry your wiring. Otherwise very well done and layed out.

[@kevin83FL]

I think he addressed and fixed this in the next video

[@pravalkushwah5115]

I was thinking about the same.

[@RaysNewLife]

hopefully he also stoped running the negative threw the frame

[@jalalalap-akalala]

Think he mixed copper and aluminium wires in a solder connector

[@kyledormoriz7065]

@@jalalalap-akalala those looked like tinned copper

[@grey_magnet]

Future build - "Here's how to build a SpaceX type spaceship on your own" - Zack. As always awesome video.

[@Dylanwhatcott]

That fuse/relay panel looks awesome

[@PRASHANTGUPTA-cs6ww]

Man you couldn't fathom my excitement for your project it feels like I'm working on it lol
