This guy should be inducted into the ATEE automotive teachers of electrical engineers Hall of Fame because he is the best of any who even tried to teach the theory of voltage drop Justin Miller I thought at the time with his trainer board does an exceptional job but this Master Meier guy has a way of really letting you understand the voltage drop thing because he does a few different videos on the same topic to make sure you understand along with great graphics on screen with explanation. Thanks A LOT PETE YOUR A GREAT MAN with a special skill of teaching that very few people are capable of doing. THANKS MR MEIER

At 21:00, when you said, "...you're going to have that 'Ah-ha!' moment, and this is all going to seem so simple to you...", I had that lightbulb finally turn on in my head whenever I went to school for HVAC. For years, I had read countless books, and watched countless KZbin videos about Electrical Theory. But I could never fully grasp the entire concept of what Potential Difference was. And believe it or not, it wasn't even my instructor at school who was teaching me whenever it all finally hit me; it was a KZbin video that I had watched! Thank someone above for KZbin! Your videos are just as great and informative as the one mentioned above! Please don't quit making these videos; they truly are a blessing to some people, such as myself.

[@nevinkuser9892]

That's great to hear. Electricity is invisible so you just have to keep at it until you understand.

[@johnturner8829]

Pete, I could sit in a class with you teaching and * Never get bored, and.. * Knowing at the end of the day I was able to learn and retain the information because of your style of teaching. I am amazed you don't have more subscribers. Always looking forward to the next video. Happy holidays to you and your family.

[@MotorAgeMagazine]

Thank you...and stay tuned! We're planning on hosting training events in 2020, starting May 9 in Chicago!

[@davidelbaz1652]

I couldn't agree more. He's a great teacher

[@yellowtrain3161]

Great info!!

[@johneric3886]

I agree with you John, Pete is alright. I put him in the top 20 speakers on KZbin nationally.

[@Barry-tp2vd]

Your teaching style is Really good ! I'm 56 and am finally learning vehicle electrics . For some reason I always thort it too complicated so formed a "mental block" !! Thankyou so much . I'll be showing other poor fools , that we can learn , if our teachers explain the basics so it can "sink in" . Cheers mate .

[@687datbabyboy]

I think I just learned more in 20 mins than what I learnt in 2 years of electrical engineering in college. Thanks!

[@MotorAgeMagazine]

Thank you!

[@iloveap83]

Im a DIYer and have spent the weekend taking notes on these videos absolutely gold! TY SO MUCH!

[@MotorAgeMagazine]

Great! That’s what I like to hear.

[@marcjones744]

Your electrical principles explanation has been the best i have found on youtube... And i have watched a number of them

[@logane7802]

you broke it down better than an unnamed powersports instructor @ an unnamed manufacturer's school in the powersports industry. i was lost in class today & watched a couple of your videos that were able to tie it all together. THANK YOU

[@MotorAgeMagazine]

I'm glad you found it helpful.

[@kingkongkenable]

I just learned more in 20 minutes than I have in the past year about basic electrical diagnostics thanks. I’ll be watching more of your videos!

[@MotorAgeMagazine]

Really glad you found it useful!

[@SAAutoRepair]

We very often become complacent knowing the "what" but never learning the "why". I personally have a tough time textbook learning. I need to see it, touch it as well as hear it. As always, you do a fantastic job explaining in this video. Thanks Pete. Hope to see you soon friend. Ride safe

[@davet1149]

I’m not a mechanic, but this has helped me immensely to understand my problems on my Freightliner. THANKS!

[@MotorAgeMagazine]

Glad you found it helpful.

[@robdoe2420]

Pete, now you've done it. I've got it, and I won't forget it. This is the video I needed.

[@davidpringuer2558]

Thanks heaps, learned some great tips by a great teacher. Diagrams made it easier to understand and the explanations were plain and simple, thank you.

[@tboneproductions2453]

Great video sir. You can buy more resistance. You can buy more voltage. You can’t buy more amperage. Dan Sullivan. Love this analogy.

[@davidche554]

After studying and watching scanner Danner lectures (Paul Danner) I came back to this video and understand it much clearer I just needed a little more explaining but now all this makes great sense! Thank u!

[@WheelsGarage]

awesome explanations, thanks for being diligent in teaching this instead of alot of short handed explanations on here

[@suggesttwo]

1. Check the fuse and battery. 2. Check for broken wires, loose or corroded connections. Unplug and re-plug. This rubs tin oxide coating off tin coating on the connections. 3. Check grounds.

[@joshuatreadway4829]

Thank you good friend for explaining so clearly your knowledge and troubleshooting skills. I will watch this over several times. Can't wait to watch more of your videos

[@deankay4434]

Pete, thank you for covering this topic. I taught for ACDelco and this was EL-3, which I encouraged techs to bring their own meters. At the dealer, confirm the concern, check all electrical items, but creates a roadmap to the problem. Starting like you said the health of the electrical system at battery, loads on-engine off, I checked drops from battery to chassis, engine and alternator. I always tell the DIYer to add a nice ground from the end housing of the alt. to the engine as this is where negative is created. Paint, grease, loose on their restoration of uncle Jakes Mustang, Chevelle or Charger creates "Problems" when repairing or installing wiring as it is a hundred+ individual circuits protected by fuses that some single fuse protects 3, 4 circuits. Using an amp clamp to size a fuse, use "Star" washers on grounds + dielectric grease to protect that connection. But most find it hard to think new wire, new connectors, switches all have my minor losses of voltage across them. Today, digital meter are better and lower priced compared to other equipment. But Red or Blk, it shows a (-) negative symbol but the same reading. How to I link this video in a comment section when in this topic? Many are visual learners and can grasp the idea better by watching! DK, ASE Master Tech since 78, retired.

[@samr.m.7709]

Absolutely an excellent video, thank you Pete for all you do

[@fredsalter1915]

Great vid, as usual. But excess electrons are concentrated at the negative pole, not the positive. Not that that matters all that much :)

[@everardocamacho5063]

Great video Mr mier, it took like 10 times watching the video to understand the concept, it is hard for some one like me than don't know much about electricity but like it a lot, thank for your time and I wish you and your family a happy merry xmas and prospero new year 2020, from Ontario ca.

[@MotorAgeMagazine]

Learning the concept of voltage drop is one of those things that will frustrate you until you get it. THEN, you'll go back and say "Wow - that was simple!"

[@sinandy6077]

Brilliant explanation. If we understand the basic concepts, life becomes so simple. You made it so simple to understand. Thanks!

[@MotorAgeMagazine]

Glad you liked it!

[@GHOOGLEMALE]

Great video again - The car you have there with one dim headlamp would be an excellent practical example of where there was likely to be an excess voltage shown on the ground side, following through such an example to its conclusion, and fixing the issue with a repeat test would really drive that home.

[@martincaldera386]

Tomorrow I´ll check my car headligts that are very dim, using your useful video, thank you a lot.

[@billyr9840]

Nice !

[@sankar7055]

What a explanation

[@harpritsinghchattha380]

Made it soo simple to understand basics of voltage drop. I have seen soo many videos making it more confusing but it was spot on sir Lots & lots love and respect

Good Afternoon Pete Meier motor age Take care and have a great day 👍 Thanks 👍 Great tutorial 👌 From Nick Ayivor from London England UK 🇬🇧

[@g.a.f3398]

Thank you so much for making this tutorial video your teaching skill is second to none you some how managed to get me to understand how Electricity works and how to test it very effectively where my previous teacher failed to get me to be able to understand whats going on in a circuit. You just break it down so simply and are so thorough it just sinks in to my Brain 🧠. Thank you very much Sir for your help.

[@MotorAgeMagazine]

Glad it helped you. There is a lot more content just like this on our home page - be sure to check it out!

I wish you were my electrical trainer during my apprenticeship as a automotive technician...would have been so much better... excellent video...great info...

[@frostieone]

Now it makes sense!!

[@lougilday1094]

Learn so much due to the step by step process. Does it change with source voltage from module’s ? Would you use the ground of the module or the negative source from the module?

[@arthurfricchione8119]

Another informative explanation Pete. Thanks for sharing 😩🇺🇸 Artie

[@tafariejones5760]

thanks for the video uncle am in training

[@elitesoccerblogs4947]

great video thank you! I was wondering can you use these same voltage drop techniques to troubleshoot an AC Circuit ?

[@MotorAgeMagazine]

Good question! I don't have enough experience with AC to answer that.
