I'm a professional educator (I develop courses and certification packages in mining, oil and gas and engineer) and tip my hat to you sir. A very well designed tutorial.
Seen any good channels about mining oil gas and engineer? Or maybe know banks that tolerate "those people"? I'm in texas so if I get involved in those fields I'll be the only person concerned with how to not die, especially since I'm not a native texan and the state bird is the "it'll be alright" aka they all want me dead as soon as I open my mouth and I'm not obese and inbred for 6 generations. They shot my Gloucestershire old spot cross male and started raising their own hogs... Then got tired of it and quit... All they do is poach deer sprinkled around the macleod gas field and sell meth... This hunter biden uproar is just shadow projection... What happened to the American dream eh?
The rarest of things on UA-cam, a concise, yet detailed explanation with clear examples and easy to understand audio and video. I learn a lot from these DIY videos and this one was as good as they get.
Excellent tutorial very well explained. Usually there are many people that are afraid to look at anything dealing with electrical concepts, but you explain it in a way that it's simple to understand. Thank you very much.
Your video is the only one that discussed checking both the resistance between pins 85 and 86, and supplying power to these pins to test the resistance between the other two pins after the relay is activated. Great job!
My girlfriend and I have been learning how to work on cars, I have much exp. I have to say your videos are the easiest and most educational ones I have EVER seen
This is an exceptionally well done video. Thank you for actually showing the internals of a relay. It makes understanding them a lot easier for a visual learner like myself.
I have to say far the best example of showing what. Everything else,was for, an the way they work. Only the first one I have seen.thank you for your time.
Very informative presentation. Been looking for a straight forward explanation and this is it. No background music, good clear sound, excellent video production and graphics. Well done.
Great video. A good example of a 5 lug relay is a high/low beam circuit. The same relay can be used to power both by supplying power on the control side when light switch is in low beam position and turning the control side off when in the high beam position.
One more vote for an informative and well presented video. It should be mentioned that if the relay is suspect and you don't have a similar relay handy, first use your voltmeter to ensure that terminal socket 30 has current. If it does, put a jumper between terminals 30 and 87 on the socket and the downstream device should be activated. If the device doesn't work with a jumpered relay socket, current isn't reaching the device and you may have a break or short along the wire. Don't leave the jumper in place after you park the car, or you may drain the battery; the circuit may not be made to carry current continuously.
No annoying techno music in the background. No rap music as an intro. No unpackaging a new relay and meter, with an explanation that he has no idea how either one works but will make an instructional video anyway. No pictures inserted into the video of his dog or a past vacation. No ads promoting crypto currency, erectile dysfunction supplements or hair loss pills. Two thumbs up, my friend. Excellent video.
What a magnificent video of explaining electrical functions in a simple and easy to understand manner. I have been a novice to electrical works but capable mechanically. This is important for me. Thanks again 👍👍👍🙏!
I just found your channel yesterday while attempting to diagnose a dead power window/lock circuit on my daily driver Lexus LS400. While I knew about 75% of the tips and tricks you so perfectly illustrated, I am very happy to have found this channel. I’m pleased with the extra 25% of knowledge I gained. But, I am even more pleased because I will be sharing these videos with my two sons who also love working on their Toyotas and also a young father I am attempting to mentor through his first car ownership. He recently bought a $650 1996 Dodge Dakota that is what I refer to as a “One of everything car” because it needs one of everything nearly. Thanks for helping me pass our cumulative knowledge to the next generation. Merry Christmas to you and your family! (Now, if I can just fix this overly complicated power window/lock/sunroof/memory seat adjustment circuit on this 1996 LS400, I’ll be happier still)
I’m still stuck on this thing. It’s a 1996 Lexus LS400. I’m getting low and/or erratic voltage at the kick panel fuse box on the power circuit and none of the doors locks, windows, sunroof, power adjustments in the seats and telescoping wheel are all inoperable. Everything else works as new. I did have an extreme amount of smoke from burning insulation under the dash in the vicinity of the kick panel fuse box. I bought a replacement unit but with Lexus security I’m wondering if I change it out will it activate the immobilizer or worse? I’m not opposed to creating a new standalone circuit/fuse/relay to bypass the stock fuse box but I thought I might ask if you thought replacing the fuse box might cause problems with other systems. It is from an identical LS400 of the same model year and options. Any help you can provide, even if it’s just to point me to where I should test with my multimeter would be greatly appreciated. I would be happy to contribute to your patreon or similar if you can help me repair or hotwire these windows, etc
Very educational and to the point.I looked for over an hour before I found this video it is exactly what I needed to know to fix my truck.Thank you sir you are a good teacher.
This is simply a superb explanation that any layman can understand. Hats off! Please keep posting such useful videos, which would help thousands of people like us.
Amazing! Only video you need to watch about relays. I'm not very good at understanding and testing automotive electrical equipment. After watching this Great video, I am confident with testing relays and how they work and what their function is. A must watch video for every diy mechanic. I'm looking forward to watching your other videos.
Great video. BTW - OL on a meter means 'overload' aka the reading is outside the range of the meter. So when measuring the resistance of an open circuit you get OL because the resistance is virtually infinite or over the range of the meter. A very high resistance will show a numerical reading in the megaohm or M range. Hope this helps. OL does not stand for open line, but it does as it turns out correspond to an open line condition.
are you over 12 ... if so you propably have a good paying job and take your car to the shop...did not have to watch video..just heading and over 8 mins to say it tells me he thinks he's really smart but really he just found out about it.. I learned that stuff as a kid when I wanted to know how things work.. bike apart at 7.. dads lawnmower at 9.. first motorcyle apart at 13 & still going in my 70's
Best explanation I've seen so far for this topic, please make more videos about practical topics with a practical demonstration & explanation as u did here :)
Trying to diagnose either a fuel pump failure or its relay, and this really helped. Thank you very much for the effort. I forgot that many relays are identical and can be interchanged.
Well done very informative. Easy to understand for one who doesn't do this every day saving critical brain cells for the actual diagnostic work. I have an intermittent start and stall that I am working on.
You explained this perfectly! I watch so many stupid videos that taught me nothing before I found this one. You helped me completely understand how these relays work & how I can test them on my own. YOU ROCK! THANK YOU!
Best explanation of what a relay does, and it how it works and how to test it. I will bookmark this video for future reference........Thank You for this learning video !
Pro grade sir. I appreciated the "hotwire the part straight to the battery" for those of us that may not be in possession of a multimeter or test light. Awesome!
Great video . This is the first time I'm following you because I had a problem with the windshield washer and the tester indicated the relay. It was very instructive for me. I learned how a relay works and is checked and about its role. You explained in a very comprehensible way. I became a member on your channel and I am convinced that I will learn many more things in this field. Thank you very much !
What an excellent lesson about relay! I have watched a few other videos about the relay, but I was still not so sure if I really understood all about it after watching them. I am so happy that now I really know about how the relay works and how to check it. What a clear, detailed, and well-illustrated tutorial video! Immediately subscribed. I have also purchased the UA-cam Premium just because I want to download this video for future reference. Thank you so much!!
Very well done, easy to follow due to simple explanations of complex problems. Thank you for not only teaching about relays but also sharing teaching methods that demystify the complex.
The best thing i found is a video of the different fuse boxes and it shows what relays and fuses go to what. Here is the catch. You could have a few fuses that are good that don't light up and switchs that are good but don't work. That is when you find what RELAY is bad. The video is called start my car . You can touch the picture of a fuse and it will show you where it is and what number and size and color. Relays TOO. 👀 Wow 👍❤ it . Note some things have to fuses and relays to the same thing. Why, ? No idea yet. 🥴😂
Without doubt, the best, most informative and most easily understood video on how relays work. I had little knowledge about how relays work before I seen your UA-cam video. Now armed with your knowledge, I can fault find (diagnose) many scenarios when my car or bike doesn't start and save myself £ or $ in garage repair costs. Good video, please make a lot more, Barry from Chester (UK).
I think we will be trying this next. I have intermittent starting issues in a 99 chevy express. Grounds are good, fuel pump, filter all-new and engaged, pressure is fine. All the other issues I see say there would be engine issues when running. When it DOES run its a champ. Now, the battery is drained (I think from us trying to start and it will not) I can only hope its this simple. I have had people say ECM and ICM. But when I read about these, they say one of they symptoms is poor performance which we do not have. Thank you for this video. Here is hoping.
Nearly perfect. I wish you would have gone over why the, what purpose does it serve to have one pin normally closed and then switch over to the other closed. But you are waaaaaaaaaaaaay better than the other videos. Thank you.
The normally closed pin can be used for anything that you want to stay powered on when the relay itself is not being powered. Let’s say I want to install a really loud aftermarket air horn for signaling while offroading but I want to keep the original car horn for normal emergency use on the road. I can cut the normal horn power wire and connect the ends to pins 30 and 87a (the normally closed pin). Without doing any other wiring at all, the horn will operate as normal, just like I never did anything to it. Now I can make a new circuit for the new horn using pins 30 and 87 (normally open). Then use a toggle switch to power the relay when I want to be able to use the new horn. Of course you want to be sure you’re using fuses for any new electrical equipment and I don’t recommend anyone add more points of potential failure into existing equipment like in this example, but that’s just one example of how I’ve used that pin in the past. Maybe a less complicated example would be to use the normally closed pin to power a warning light letting you know that you haven’t turned something on yet, that you really should turn on. Once you turn the thing on, using that relay, pin 87a is no longer powered and your warning light turns off. I used one that way for my dash cam system. If I happened to forget to turn it on I would notice that light pretty soon after getting settled in and moving.
I am amazed by how good this video was considering that I am still learning electrical stuff, and I have a hard time understanding from some people. Thanks for the video ❤
Well done, easy video to follow. I always had a good understanding of a relay but this was a good refresher. I have a 2019 Kia Sorento and the Map lights inside the car are not turning on. I have power when I manually turn the lights on but the lights will not go on when the door opens or for the button that turns all the dome lights on. So it cold be the diode in the car lamp assembly or the relay is your video suggested. Thanks and good tip for switching out the relay and trying them in different spots.
In older vehicles, it is prudent to replace Relays in the 20 to 25 year range proactively. The cost is modest. While most Relays will probably never reach their open/close cycle life, age can and will compromise their integrity over time. Swapping Relays can be a quick fix to get you up and going... but who wants to crack the hood and troubleshoot on a cold winter morning when you are running late for work or school. Just something to think about. Great Video!
Ive watched many videos on what a relay is, what it does and how it works. Your video is the best Ive seen. Excellent Job. I also love the how to test a relay part as well. I have a much better understanding and learned so much more
Best vid on this subject by far. Most don't include the detailed troubleshooting to see if the relay is even getting any power. Just checking the relay is only part of the troubleshoot. Thank you for this video. Liked & Subscribed
i have to thank you for taking the time to educate me on relays. Saved me allot of cussing at these smart cars. Good job on keeping it short and to the point👍🏻😅
Hands down my favorite creator and I just found you, you make what my brain can understand actually able to understand. I’ll be a forever subscriber and I’ll continue watching all the videos today!
thank you...a very thorough and concise bit of information and is more than enough, when put in practice, to eliminate error when testing a switch. ... peace.
Wow that was an exceptional tutorial. Nice imagery as well. My Dad was an electronics engineer. Usually I call him for advice on relays... But he's gone now. Thanks for being there!
I have a tool called a power probe, it's a glorified 12vdc test light that can also inject power or ground, and has a ground wire with alligator clip at the tool handle just for the purpose of testing components. This tool in conjunction with a beeping continuity tester on my multi-meter makes it very easy to test relays. Relays are incredible devices. Very fascinating. I have a 28 year old beater car that I keep for emergencies and recently the electronic radiator fans stopped running. The module to get them working again was a couple hundred dollars. By troubleshooting the relays for the fans I discovered the module grounded the coil on the relay which turned on the fans. So I added a relay which is triggered by the accessory switch that grounded the coil on the fan relay, effectively turning on the fan while the car is running for about $5. I know it isn't the proper solution but my car isn't overheating.

Excellent tutorial. Good explanation for understanding. Thank you very much.
Wow that was an exceptional tutorial. Nice imagery as well.
My Dad was an electronics engineer. Usually I call him for advice on relays... But he's gone now.
Thanks for being there!
I have a tool called a power probe, it's a glorified 12vdc test light that can also inject power or ground, and has a ground wire with alligator clip at the tool handle just for the purpose of testing components. This tool in conjunction with a beeping continuity tester on my multi-meter makes it very easy to test relays.
Relays are incredible devices. Very fascinating. I have a 28 year old beater car that I keep for emergencies and recently the electronic radiator fans stopped running. The module to get them working again was a couple hundred dollars. By troubleshooting the relays for the fans I discovered the module grounded the coil on the relay which turned on the fans. So I added a relay which is triggered by the accessory switch that grounded the coil on the fan relay, effectively turning on the fan while the car is running for about $5. I know it isn't the proper solution but my car isn't overheating.
This is a brilliant video! You should be a Science teacher! Fab explanation
Very comprehensive and masterly Organized video ..
Your videos are worth their weight in gold! Thanks man 👍👍👍
