Where was this video the other day RUclips?!?!? I HATE how RUclips hides the good videos when you are relentlessly searching for explanations. Then about 2 days later RUclips like hey and there’s this video you may like..but it’s on purpose. If RUclips let you see this video first then you wouldn’t need to spend half a Saturday on their website. Great vid thanks
Great video about relays. FYI when you start comparing 110VAC to 12VDC something should be understood. When talking about power you are dealing with Watts (V*A=W), not just current or voltage alone. Your AC unit is pulling 12amps at 110VAC so it's using 1320Watts. Your 50 watt car fans are running at 12V, so they are using 600Watts. So your car fans are using half the "power" of your house AC unit. I realize you are mostly talking about amperage in this video but it's a little misleading to say amps are amps and leave it at that. Thanks for video.
But it's the current that determines the thickness of wire required and the voltage drop through that wire. If your car had a 1000V battery there'd be no need for relays on anything that draws less than 100W... halogen headlights would draw 50mA and could be supplied with the same wiring that currently is used to switch the relays.
Bro, I was thinking that relay was going to smoke with that 120v power source, but I figured it wouldn't or this video wouldn't be posted up. Definitely one of the best explanations and coolest demonstrations I've seen. Nice Job!
i'm an electrical buffoon but i am trying to set up something in my car. if i understand how something works it makes more sense than a video of someone just assembling something. thank you!!
no you didnt include a ton of technical jargon and math but after watching 20 different vids on this topic this my favorite...everything finally clicked after watching your video. thank you, now i am going to properly wire or re wire a good portion of my 20 yo plow truck. awesome
Chris you did an absolute superb job in breaking down your tutorial in a very basic, understandable way for novices like me to understand. You even explained the terms you used like "load", not assuming your audience understand the electrical lingo. I was so grateful how you did not presume knowledge on your audience. I mean for those who understand electronics they would not even need these basic tutorials. It is people like myself who are trying to become educated in the area and it is only due to the extent you went that makes things so clear and understandable. I am so grateful that you broke things down in elementary terms, as that is exactly what I was looking for. Again, thanks so much for knowing your audience and those whom you were trying to reach. I am a student of your videos and I importune you to keep up the good work. Us novices out here need people like you
Charlester Williams I second that. Did you get a good laugh like myself at the “dumbass” part? Haha. It was unexpected and I guess that’s why it had me cracking up. GoodtimeS
Watching again.i don’t use these very often so i have to relearn every time I use them, I ju sad t watch your videos and it all comes back( for the moment) I’m old and don’t remember like I used to. Thanks ( Bob) love the fact you have a 70 . And I love the dumb ass😂😂😂
I appreciate that you have specified the wire gauge (10 AWG) ... trying to do DIY ... no knowledge about electrical but I have background in computer network cabling ...
"Relays for Dummies", now I know the explanation and the application, Good for you Chris, talking at a very basic level and bringing us along, Teacher!
Hopefully this make people realize that when you have a relay go bad like I did, just open the hood and swap it with another identical relay with the same value that was working fine in another circuit of the vehicle. This can help you get back on the road quick, even though you may have to run without your AC, Radio, or some other accessory until you get to Autozone or somewhere to replace it.
In a pinch you can pop the cap off a relay and zip tie the spring mechanism so the circuit stays closed by looping the zip tie between the terminals on the bottom of the relay and back up and over the switch mechanism
Thank you . Been battling my high compression 327 SBC in my 66 k10 . Old wiring had a melt down confused the shit out of myself with relay in my brain malfunction. Your vids straightened out my minds iron for no loss contact good as gold. You the man on this subject explaining points , s & r on solenoid back to coil three resistor old school which is where my mind circuit went South .I am all over it now like cheap polyester for the finish actually totally understand exactly WTD PRICLESS.
thank you ive been watching videos on relays vs fuse blocks for two days. this is the first one ive found that explained it in a way that i totally understand what a relay is, why, and how you use it.
It's amazing how many videos I watched on how to hook up aftermarket lights that basically explain nothing about HOW IT WORKS. From those of us who want to know HOW instead of just slapping something together per instructions, thank you. This video was invaluable in hooking up my lights safely and cleanly, just wish I'd found it before I fried 30-feet of wire and wasted 50 bucks.
Very informative tutorial for those of us in the trucking business... as some viewers may know.... drivers are constantly installing rocker switches to power the lights on our rigs its actually an obsession with a right of passage....feeling confident to take it a step farther and boost up my bunk heater or maybe install a good floor heater on aux power ,thx Chris been a subscriber for almost a year keep up the inspirational videos P.S I'm wondering if an automatic boxing glove that pops out of my front bumper would be carrying things too far 👊
Thanks sooo much for sharing THAT. I just got SCHOOLED. Will use a relay every time now. Always use fuses but this really opened my eyes about heat and voltage drop. Thanks man
Awesome vid! Love the straight forward explanation here. I thought I understood relays since I installed a few in the past but I never really looked at it quite like you explained it here, Thank you!
Good video but there's something he didn't mention that you ought to know. In the case of relays that don't have or don't use the 87a pin, it doesn't matter which pin, 30 or 87, the load is wired to so long as the other pin in the pair is hot. Likewise if the relay has no diode in the control circuit then it doesn't matter which pin, 86 or 85 is hot, so long as the other one will complete the circuit to ground. Knowing this will save you a lot of head scratching if you're looking at a wiring diagram but the orientation of the relay in your car seems to be applying power to the wrong pins.
Awesome job, planning a lighting wiring job on my side by side and needed to understand why/where the relay comes into play, want DRL to work when keyed/ignition in on, full LED off the switch. Makes perfect sense now...
Love your videos man these have really taught me a lot. I could pay a few hundred dollars and have it done or watch your videos and be able to say I’ve done all the work on my car. Thank you!
Your video is absolutely outstanding outstanding please keep putting them out I enjoy them they're full of information and we appreciate everything you're doing
Easy to understand. I like the no bull shit interpretation you give. None of the scientific jargon we don’t need to know! It’s either on or off or getting overloaded or not, why the relay is used, and what could potentially happen if it wasn’t used! Subbed!
Авто/Мото
I RARELY LEAVE COMMENTS BUT DUDE I DEFINETLY WANT TO SAY YOU EXPLAINED IT GREAT. THANKS FOR BEING SO CLEAR HOW IT WORKS
Finally !!!
After being in the Automotive industry for many years, this is the most simple explanation ever..
Great job !!
Do I need to spend extra money on thicker wires, or extra money on a relay?
agreed. straight forward and easy to catch up! 👍🏻
This guy needs to lay off the meth.

Brother.....you knocked this one out of the ball park. Why some people make it so complicated??? Thanks
Planning on setting up work lights on my truck, this explained it the best I've heard. Thank you very much .
I have a wiring a relay in real life video too

Saved me some typing, my thoughts exactly lol. Agreed still a great video though👌🏽

I've watched several videos but this explains it better than any of them
Best video on the internet. Thank you so much for making this, I've even taken screen shots to quickly remember things you said.
I like how you’ve combined theory and practical….keep posting more
Bro, I was thinking that relay was going to smoke with that 120v power source, but I figured it wouldn't or this video wouldn't be posted up. Definitely one of the best explanations and coolest demonstrations I've seen. Nice Job!
I don’t normally leave comments, but I come back to this video time and time again for a refresher. Thanks for doing it. I really appreciate it.
Always loved running relays, relay boxes, fuses and fuse boxes for a new, clean install.
Great confirmation information in this video!
I’ve learned a heap watching your videos on the use and need for relays and the wiring up for your double cooling fan setup! Thanks a million.
i'm an electrical buffoon but i am trying to set up something in my car. if i understand how something works it makes more sense than a video of someone just assembling something. thank you!!
Fantastic! Plain talk, thoroughly explained. I liked the instructor and in 13min I understand. Good teachers are hard to come by. Thank you
no you didnt include a ton of technical jargon and math but after watching 20 different vids on this topic this my favorite...everything finally clicked after watching your video. thank you, now i am going to properly wire or re wire a good portion of my 20 yo plow truck. awesome

Thanks ( Bob) love the fact you have a 70 .
And I love the dumb ass😂😂😂
I FINALLY understand relays. Well explained. Detailed, to the point, and great visuals. THANK YOU!!!
Damn, that a/c example really showed exactly how and why for relays! Thank you
This is a very informative and easy description of how a relay works mebeing a mechy ,electrics can be so confusing, well done Chris.
I appreciate that you have specified the wire gauge (10 AWG) ... trying to do DIY ... no knowledge about electrical but I have background in computer network cabling ...
"Relays for Dummies", now I know the explanation and the application, Good for you Chris, talking at a very basic level and bringing us along, Teacher!
Simple, clear, zero-bullshit explanation. Thanks Chris
Finally an easy-to-understand video on relays. Very helpful thank you
I'm late to the game here, but that was really well explained...really well. Thanks.
One of the best videos on relays! Applied thanks 🙏🏽
Awesome explanation !!! I am a HVAC control tech,, You have done an amazing job of displaying in simple terms !!
Great video man! ANYONE with any questions about relays needs to watch this. Saving this to my favorites so I can send it to other folks when needed.
It took a while, thanks to your video of a practical example, I finally figured how the relay works.
Badass demo. One Hell of a way for dumbing it down for hands on people like me lol Good shit Chris.
How something so simple could be so difficult to explain is astounding! Thanks so much!

In the first two minutes of the video you demystified how to wire a relay. Great job...Thanks!
Thank you . Been battling my high compression 327 SBC in my 66 k10 . Old wiring had a melt down confused the shit out of myself with relay in my brain malfunction. Your vids straightened out my minds iron for no loss contact good as gold.

This video was invaluable in hooking up my lights safely and cleanly, just wish I'd found it before I fried 30-feet of wire and wasted 50 bucks.
I have a video “wiring a relay in real life” where I wire up my KC lights on my Jeep
Thanks so much for your easy to understand explanation of the relay, I am a auto tech by profession and I found it to be an excellent training vid.
5:40 the "known rule" as he puts it, is that in any electrical application, terminal 30 is commonly used to designate a direct (hot) battery lead.
What I was looking for. Thank you!
This right here is the point of the internet. Thank you for this. I'm learning more about how cars work!
You helped me a lot , you helped the most actually , thank you .
Very informative tutorial for those of us in the trucking business... as some viewers may know.... drivers are constantly installing rocker switches to power the lights on our rigs its actually an obsession with a right of passage....feeling confident to take it a step farther and boost up my bunk heater or maybe install a good floor heater on aux power ,thx Chris been a subscriber for almost a year keep up the inspirational videos P.S I'm wondering if an automatic boxing glove that pops out of my front bumper would be carrying things too far 👊
Thaks dude very good explanation 👍
Thanks Chris - been struggling with this for a while. Really clear and appreciated !
THANK YOU!!! Simple, to the point, nothing fancy, just facts...
Man I’m really impressed that the relay could run that ac unit.
You explained what I was wondering for a while about direct switches
Thanks very informative and practical.
Thank you I now understand number 30 and 87 . It always was a big mystery to me.
Such a clear explanation! Thank you!
Thanks sooo much for sharing THAT. I just got SCHOOLED. Will use a relay every time now. Always use fuses but this really opened my eyes about heat and voltage drop. Thanks man
"this is why they use this freakin relay" lol you cracked me up lmfaooo love it!!!
Brother this is the best RUclips video for education on relays, simple and direct . Many thanks from Australia 🇦🇺
Beautifully explained. Thank you
I never leave comments. Ever. Thanks for explaining this the way you did. It’s a great introduction to auto relays
Awesome vid! Love the straight forward explanation here. I thought I understood relays since I installed a few in the past but I never really looked at it quite like you explained it here, Thank you!
great video about relays!!
Hi Chris,thank you so much for this. Had installed one on my bike. 😀

Finally. Thank you for explaining this stuff in a way that's simple. You're my new favorite. Thanks.
Excellent demonstration LOVE IT!
I enjoyed your video. It was very helpful. Thank you!
Awesom video thanks for your share thumbs yup !!
I really enjoyed this video thanks for sharing! 👍
Thanks for the advice Chris.
Best explanation/tutorial I've seen yet. Excellent job !
Thanks for the effort,
Karl
Awesome job, planning a lighting wiring job on my side by side and needed to understand why/where the relay comes into play, want DRL to work when keyed/ignition in on, full LED off the switch. Makes perfect sense now...
Great video and thanks for this video.
Love your videos man these have really taught me a lot. I could pay a few hundred dollars and have it done or watch your videos and be able to say I’ve done all the work on my car. Thank you!
This was very informative. Now I understand relays finally.
Could you do a video on a relay+fusebox build?
Relays were just a mystery to me before this video. Great video. Thanks
Excellent video thank you!
awesome video... Thank you for doing all the work to show how to properly wire up and how a relay works properly!!! great video!
Great info...thanks !
Very precised explanations! Thank you so much!
Wonderful video . Thanks.
awesome video..thank you for sharing
Got it in first 2 mind and been reading about a simple reverse camera circuit for a while but now it's really simple... thanks
sir thanks to you i figure out how to use a relay and the simple way you put it was freaking awesome
Simple & clear. Some people make connecting a relay sound like rocket science. This is so well explained and the reason for using a relay.
Around 5:38 in this video, you had me LOLing😂. Good stuff.
Good explanation...thank you 👍🏻
All the time I've been doing car audio I never used one of these lol. But running leds and fans its time. So I appreciate the breakdown! 👏
This is the Best video about relays thanks alot
I know this is an older video, but your spot in, Great work on explaining it w/ diagrams. . .
Great video. Thanks.
Your video is absolutely outstanding outstanding please keep putting them out I enjoy them they're full of information and we appreciate everything you're doing
Perfect demo
[WOW] NICE. Best video I've seen in a long time. Thanks
Thanks so much for time & explaining this diagram...
Clear, Concise, ,& Understandable for the average leyman 👍
outstanding explanation for us lay people. Easy to understand, Thanks for your video.
Phenomenal explanation
Awesome instructional video. Thank you!
Now I got confident when adding a relay to the head beam circuit of my car. Thanks
Very informative. Thanks!
perfect vid. Need to do this on a project and you nailed it.
Good demonstration and good diagram 👍 thanks for sharing your knowledge.
