I KNOW how much thought, effort, and experience was involved in producing this series!!!!

[@Michael-jp9jw]

Wow! This tutorial is awesome. So glad to have found this video!

[@rad4627]

Many years ago as I watch this video currently. Ain’t nobody better, this guy is the gospel for teaching.

[@realfixesrealfast]

Thanks, I appreciate your comments

[@pedrocervantes7839]

I was thinking take some automotive electric class but when I found your channel and especially your diagrams explanation y thought is not necessary spend money when I have this amazing chanel whit the best teacher who have a lot of experience. THANK YOU.

[@Eurocano]

You are a super teacher, clear, structured and objective, great lessons ! I appreciate all your work, thanks !

[@nicholasdancewicz3856]

Fantastic. I could learn from you all day! Love it!

[@jamesbarratt593]

11/10 and thats the truth. Calm mannor and gentle voice. Everything thats needed to be a great instructor. I have watched a few videos today and only when I started watching yours did I find that it all made sense. Power usually drawn at the top, fuses only on power side, and the drawings drawn at rest. Also the dotted outlines. Thanks pal.

[@geojor]

excellent learning video...

[@ClaudinneV]

Thank you very much! Very good quality, editing, voice, teaching method. Worth to share and recommend!

[@psychomantismgs]

Great refresher videos. Been about 5 years since I've worked with schematics and this brought my knowledge right back.

[@automotivepalace1]

Sir, thanks a million for the awesome job you are doing. Because of you I have become a better tech and I am striving for excellence in the auto repair industry.

[@scooter12368]

appreciate all the work that goes into this productions. titles, graphics , voice over. really enhanced video. hope others realize that. if they don't at least the editor and you and i did. thanks

[@breeze787]

Yup! Did what you said and colored hot and ground as I thought it might work. And this exercise helped me keep up with your explanations having studied it somewhat and gave me a deeper understanding right off the bat. It was like being prepared for the oncoming lecture. Thanks for also getting into troubleshooting the resistor that was awesome.

[@eliezerramosjr1017]

Very understandable and I never went to school. Very thorough teacher, thanx Doc👍🏾👍🏾

Informative and what an easy to understand, thank you. Wish that those newer toyota diagrams was using same rules..

[@Rick-tb4so]

Your video is the BEST I have ever seen. Teaching is all about having your students understand..If they dont understand its the teachers fault..

[@christosthecrt]

excellent, thank you! waiting for the next lesson 3.

[@Hurlburton]

I started looking at this video today. This video is good I mean really good. I had a look at that July motor article too. Excellent article. The problem with the blower when only 4 and 5 speeds work is the fuse in between 3 and 4. If it was the blower it wouldn't work at any speed.

[@realfixesrealfast]

Thanks, I appreciate you taking the time to comment. You will be blessed by your effort to teach the new people.

[@electricianhq7049]

this is by far the best electrical diagram resource I have seen online and I watch a LOT of these videos. The suggestion to color the circuit ourselves first was key, then when you explain, it all comes together.

[@realfixesrealfast]

[@OKRODDER]

Hello, I really enjoy your videos. I was wondering what your thought were on products like the power probe. I have been considering purchasing a short detector to help me troubleshoot electrical issues quicker.

[@syed22]

as a new Protection and control Engineer i find this very helpful. Please can you make videos on how to design relay protection please

[@richardbryanesq]

Great job. I would suggest more use of a pointing device when you're narrating because sometimes the viewer gets lost as to where in the diagram you're referring to. So it was great when the probe appeared for example to show the testing of resistors 4 and 5, but that could have been left on the screen for more than 1/2 second, and then prior to that it was sometimes difficult to follow where on the diagram the narrator was talking about. A cursor object would have been more helpful. Nevertheless thanks again. Hopefully also at some point in the series you will take these lessons and show the testing procedure in action inside a garage so the viewer can connect the classroom instruction to real life. Because you don't put the electrical probe to a piece of paper. Show the viewer, please, how to transfer the electrical diagram to the actual circuit in the automobile. I'm looking forward to watching the rest of the series.

[@spelunkerd]

For those who don't want to go through the effort of finding a jpg file with the diagram, here's a quick way to do a screen grab on the Mac. Choose highest quality resolution, play the video in full screen, then hit pause when you want to make a still image. Then hit shift-command-3, all three keys at once. A png file will appear on the desktop, which can be modified in Photoshop to whatever format you want.

[@MariaTorres-zv8df]

Question. When the mechanical dial selector is turned to any of the speeds, Why is the front blower motor relay is colored Red and not Yellow. As I understand once the selector activates the ground that should be switched ground not direct ground. So, it should be yellow. Am I right or wrong?.

[@musicallegend8732]

Maria Torres Red is direct power to relay and stop insides at open switch at all times. Orange is switched power feeds to motor when relay is energized with integrated ground as dotted lines means there more pins to it. Hope you understand what I meant.

[@dmorley100]

I think these lessons could be further enhanced if an actual electrical multimeter were used in the hypothetical testing instead of a PowerProbe. You can get a multimeter at Lowes, AutoZone, etc. for around 20 bucks or so, so it's much easier to get than a PowerProbe. I used to be pretty anti-PowerProbe several years ago cause I thought it was a crutch for people who didn't know how to do basic electrical testing. I've softened my stance on it somewhat now, but still kinda feel the same way.

[@musicallegend8732]

Quick question, orange power runs through resisters so the power will be dropped drastically by the time it feeds motor right ? It looks like only switched ground is being run through the resisters to feed the motor. I'm kinda lost there. Technically switched power is only straight power to devices ?

[@costelmihaila8520]

very amazing

[@lonnydohner5449]

If you could put up a wiring diagrahm of a trail blazer that would be really helpful please and thanks

[@muikunruoto]

Turn it to full screen, all text is readable. What part of the 4 resistors you had trouble with? About using power probe to find problem? He would point the probe to the 1st position on the resistor, turn the blower motor switch and see at which speeds probe finds ground. Then he would do the same for other resistor positions. And all the resistors are connected, so if no. 3 is burned out, blower works only in speeds 4 & 5 cause in speeds 1-3 current flow to motor stops at the burned resistor.

[@muhammadrafiqulislamkhan6994]

Thank you Sir.

[@jksguitarandmusic781]

This is a great explanation on diagrams. Sure made me look at thing's a different way. Great work, have you done a video on tube amplifiers?

[@realfixesrealfast]

No I have not but I'll look into it

[@davenerr]

Im ready for lesson 3.

[@davenerr]

1, 2 and 3 will have ground on the power probe only green light,but will not have power red light on the power probe, thus a broken connection in the blower motor resister.4 and 5 will have power (red) and ground (green) on the power probe. showing a complete path on the power and ground side thereby showing that the problem is in the blower motor resistor.

[@jerryherron6548]

GREAT!

[@yanjiang9976]

thank you so much for the diagram

[@HaroRider03088]

Is it possible to just check for continuity between pins 1-3 and 4-5? If the resistor is bad it would just be open? Or does it not work like that

[@29CFV]

Great video, at 5:48 he mentions that when the dial on the HVAC is turned to the #5 position that ground is supplied to the Front Control Module...how did he know that? I can't see how they are connected via the diagram. I know he states that control modules have more components than what is shown so would I have to go to the "Front Control Module" diagram to see how it's connected to the HVAC control? Someone please clear this up for me.

[@phillipbarr1870]

It finally clicked with your video! I read all the additional readings from my books and still didn't manage to understand. Thanks for the help.

[@tammyghashghaie6242]

its a great and i have never seen video + get the free diagram. If the characters (graphic) of video was more dark then would be excellent to learn at real time

[@TheIanmurphy]

Great video. But how could you tell by looking at this that the HVAC control was going to provide ground for the front control module? Is it explicitly indicated you do you just know that from experience?

[@realfixesrealfast]

Good question. Remember this . . . all working circuits need power & ground. The front control module was supplied power but not ground (at rest). With power provided but no ground it could not operate. So, the logical answer is that the HVAC control must supply the ground. The ONLY other option would be for the HVAC control to supply power, but power and power will not complete a circuit so the load can WORK. Hope this helps.

[@SicQueldorei]

He has an older video on his channel that shows how to use a power probe to do basic electrical testing

[@alfredgavina3285]

I would like to follow along with the schematics that you claim are on your web page but it says Not found. Can you help?

[@0mniessence548]

thank you

[@alleviate9546]

If the fuse in the integrated power module were to melt due to overload, would it be an open?

[@realfixesrealfast]

yes it would

[@floridaroadracerguy]

In the beginning of the video you stated that the current would change depending upon the resistance, thereby changing the speed of the motor. Actually the Voltage is reduced depending on the number of resistors it is dropping across. Current draw remains the same. Ohms law.. Take any dc motor and try changing the voltage and see what happens.

[@izbavynasotlukavago]

Why doesn't the diagram show the ignition switch between the battery and the front blower relay? Does this just go without saying?

[@rockdownful]

How do you know that the HVAC control sends ground to the front control module when switched on? I don't see an electrical connection there. Everything else was crystal clear!

[@robertmccully2792]

Good video... I have been wondering how to learn more. It came to me-- a diagram is the cheapest easiest way. The problem is where do yi get diagrams for any year and model cheap? There must be one location somewhere?

[@_JuicyJ]

What power probe are you using in this video?

[@yz250chick]

I can't find the diagram on your web site to print it out. Please help!

[@nathancollins981]

Why does the path from the 40 Amp fuse go through the Blower Motor Resistor Box, even though it doesn't seem to attach to anything until it reaches the Front Blower Motor?

[@ryccoh]

Yeah I was wondering the same thing, how are you supposed to recognize a connection when it's not drawn in.

[@kedzielewski81]

I can't really find these cir diagrams to print out, any directions where to find them will be appreciated. Thanks.

[@habakkuksam]

This very good time to study view thing here

[@barneygordon2585]

is the purpose of a front control module just to send grounds?

[@keeping-up-with-pg]

after watching halfway through i finally why test the harness that connects to the load. to make sure it has power and ground.

[@nicholas8479]

at 6:00, I don't see how the "HVAC CONTROL" sends ground to the "FRONT CONTROL MODULE". The diagram does not show any physical connection. According to the diagram, turning the control knob will only send ground to the right side of the relay (pin 87) . Please explain.

[@tiberio1352]

Nich, remember, they are both in DOTTED boxes which mean they are the same element , even if they are spaced apart. Once one activates so does the other. Hope this helped you

[@DAQUAN88]

@11:26 Blower motor resistor is bad you mean?

[@HenrikAlfsvag]

How do you know that the HVAC Control will send ground to the Front Control Module?

[@DaPobster]

the blower motor is the problem? wouldn't the the resister be the problem?

[@joshuareynolds6963]

This is what I was thinking.

[@danielpalmateer9335]

hi. I'm interested in printing out the diagram but it won't let me. when I click on the link it takes me to a page that says no found

[@ekawakakonahi1174]

Does electrical current flow @ different speeds, really ?

[@TheIanmurphy]

Ekawaka Konahi No it doesn't flow at different speeds. He was saying faster speed in reference to the blower motor speed. Lower resistance = more current = faster motor

[@rickdeckard2769]

Good video overall, but there is a mistake in the coloring. Not all the paths draw in yellow through the resistors should not be colored when you switch the rotary switch on. To be accurate it should only show the path connected via the rotary switch. e.g. #5 or #2 as shown in the video. Highlighting them all yellow implies that voltage is flowing through all of them which is not the case. Also, you misspelled resistors around 7:16:-)

[@christosthecrt]

I think the answer is this: the hvac and the front control module are both in dotted line boxes, so a lot of thing are missing.

[@TotemoGaijin]

I almost followed what he was talking about in the first video, then he went from 0-60 in a second, lol.

I have a electrical schematic for a Howard Price 727 Turfmaster mower. The schematic does not look anything like the new schematics. This is for a 27 horsepower Yanmar engine. The unit had been taken apart (electrical) because the plug inside the panel from the frame had worn through the plastic. I need to rewire the entire unit (12 pin connectors from engine to panel). I need help to get the unit back to being functional. Any thoughts where I could get some help? The company is out of business and the Yanmar corporation doesn't have the manufacturers information other than parts numbers. Thank you. I'm in Reno, Nevada and need help.

[@strokewarrior5762]

sorry for delay. There are aftermarket companies that rebuild complete wire harnesses. Or do it yourself. Wires are like roads on a map. Each one starts at some point and leads to another point. If you take it completely out you should be able to rebuild it.
