this is the best explained where terminals connect and how they work iv looked all over . and listened and watched lunatics but none could tell me where the terminals go . thank you very much for this vid

Last month in Calgary, a 'sting' operation by a local journalist was done at about a dozen auto-shops. They brought a vehicle in with a bad ground connection at the battery. More than 3/4 of the shops sold the customer an unnecessary battery. As I recall, all three Canadian tire shops missed the diagnosis. Only one or two of the whole group did a voltage drop test and thus came to a correct diagnosis. I admired the one mechanic who admitted he messed up. Good review.

Thank you so much for taking the time with this educational video. Your use of hand-drawn diagrams with the actual multimeter probes makes things so easy to visualize, even for a backyward DIY enthusiast like myself who has no background in electronics.

I have a real aversion for 12v electrics but this is the clearest, most logical explanation of fault diagnosis that I have ever seen! Even I could follow it! Thank you Sir!

9-1/2 years later, You are a good teacher. What seems scary to the uninformed now make perfect sense. Time to go out and give it a try. Thank you.

I saw a few comments say it was best starter info video ever and figured it would be a little helpful... And I was far from right, it was tons and tons of help. it was very detailed, very easy to comprehend and had visuals without being under a hood with every other part to destract us.. I will be doing all of this with ease tomorrow. Thank you very much!

A timeless video! This information is applicable to both a 1957 Chevy Bel-Air and a 1995 Dodge Pick-up truck.

Thank you so much! Ive often stared at wiring diagrams and had no clue where to begin. Ive now narrowed down the problem thanks to your video and am confident on how to fix my no start issue.

My dad spent hours and several videos trying to find an answer, and he finally found it through this video! Thank you for your help

I have a circuit analysis midterm next week but my car also refused to start today. This video has just helped me on so many levels. Thank you.

thanks so much John! it ended up being the starter after all!!! Putting that thing in 2x was a pain, but sure made me do a happy dance when the warranty replacement went in & worked! Thanks so much for taking the time to help me and so many others- you saved me hundred$

Excellent video. Very straight forward explanation. Having the explanation of the voltage strengths and how to test it is very helpful. Thank you.

Thanks for your generosity, skills and efforts to help us understand the subject.

Great video indeed! I was able to diagnose the problem with my Mazda 3, which would sometimes start and other times I would get nothing. When it didn't work, battery was fully charged and I would not even hear anything turn over. With knowledge learned on this video, I located the starter wire and by wiggling it, it would close the connection and the starter would work. But another slight wiggle and nothing would happen. It ended up being so much of a problem that mazda release a service bulleting to remedy it in 2008. I hope anybody with the same problem will find this video and maybe read my comments to save them hours and dollars. The replacement part is under $20, for a new wire connector (BAY0-67-SH0). Thanks again for the perfectly explained video!

I'm improved my understanding not only of starters but of wiring diagrams and this is just great. Thanks lot !

This is the best video I have ever seen on KZfaq is like taking a mechanic's class a college will not even break it down in detail like he did thanks my friend

By far the most informative video I have seen on the subject. Big help with my VW T25

Outstanding Video! Your approach using diagrams drawn on paper and actual meter probes in your hands is very practical and easily understood. This is the best instructional video I have seen on youtube thus far. Thank You!

This video was so freaking helpful I’ve been screwing around with this lawnmower for three weeks bypassing safety switches and all that! Finally got it fixed!

Probably the most informative youtube video i've ever seen. Awesome . I'd have you on my team in a heartbeat. Just noticed this was 2010 , it's 2018 now hope your still alive and good.

that was the absolute clearest explanation I have ever heard - thanks, it even made sense to me who only used a voltmeter once - lol!!!

Well worth watching till the end. So clear.

Very good video and easy to follow tutorial. Although I do a lot of work on cars it's easy to forget the basics like these so this was a good recap and very clearly presented. Thanks for taking the time to put it together and post it up!

Really helpful and informative - thanks for taking the time and effort to help others!!!

Thank you for this great video. I've saved it to my watch list because of the fact that I have a perfect memory, just not a long memory.

This may be the single most clear and perfect starter diagnosis video on youtube as far as I can tell. Very good explanations and perfect use of drawing and multimeter lead orchestration while narrating us through the process. You, sir, have a talent for teaching..

Brilliant instructional video. Crystal clear explanation. Another multimeter is sold. Thanks!

I love how clear you are in your explanations.. I would love to learn how to rebuild my 75 chevy van from you .. thanks

This is a brilliantly clear and fascinating video that even a mechanical doltard like me can understand. With the easily understandable language and fantastically clear diagrams I actually found it fascinating. Now I'm off to try and fix my malfunctioning ignition/ starter motor problem myself!!! THANKYOU!!!!!!

This was the most helpful and thorough electrical problem troubleshooting video I've ever seen! Thank you so much! Please continue to post such awesome videos!

Very well explained and all the needed metrics. Never seen it explained so well, thanks

Crystal clear, Best explanation, I have found, Thank you.

I've watched 10 or 12 videos, looking for a simple, logical explanation for starter system issues based on the function of the starter and potential symptoms related thereto. This has by far been the BEST video for that. I thank you sincerely for your help. By the way, what an ingenius idea, for teaching purposes, to touch the actual voltmeter leads to the appropriate places on the drawing! I wish you every success in your endeavors.

10 years later and this guy is helping me with my current problem! AWESOME!! Thank You!!! "Current problem" see what I did there? I crack myself up. 🤣😂👍

Super explanation. Short, Clear, and to the point. Excellent skill on your part to teach this material. Thank you much. I am pretty sure I can find the problem on my 1999 Suburban tomorrow. I got a feeling that one of the cable is not good and with this instruction I will know the truth.

Man that is very in depth! Thanks a lot! I was just charged 100 dollars for a diagnosis and they said I needed a starter. Using your video I was able to remove the starter and bench test it myself and my starter works fine. Unfortunately, I already bought the new starter. I will probably go ahead and change it anyway. But I spent 200 on a part I didnt even need because of their wrong diagnosis. Calling them back tomorrow. I'm about 400 dollars in on this same old issue. I've been to 3 different shops and nobody seems to be willing to take the time to dig into a real diagnosis always got their hands out to collect payment. I'm going to be so pissed if I find out it was a simple bad electrical connection somewhere and only a few mins or few bucks fix after I've spent hundreds getting nothing done.

The best video ever I have found among all other starter videos. I like how you explained it with the diagram. Very easy to follow.

Outstanding explanation. If everybody explain like you.... Great !

You are an awesome teacher! Step by step instructions that even a dummy like me can understand. Thank you!

Thank you for doing this video! Saved me a lot of time and money trouble shooting my van.

Dam good explanation without all the BS . Thank you very much .

Absolutely amazing video, right to the point, easy to understand, and short and sweet.

Helped me IMMENSELY with my custom loom for a project car. Thank you thank you!

Brilliant,very clear explanation. Right now I'm back to the boat to trouble shoot my problem. Thanks a bunch. Rob

Thank you best starter vid ive seen so far !

Very, very well explained and easy to be able to hear everything that was being said on the whole video!!! So great job mate and please keep up your good work!!! :)

Very good video for the backyard guys. Wish I would have seen it earlier and did these tests. Mine would sometimes click once or twice then crank over. Instead, I visually inspected all wires and connections and found the positive at the solenoid looked burnt and corroded somewhat. Your explanation of a click no crank sounded correct. I just cut the connector and I'm going to replace it. I recommend to anyone that ALL connections be clean and solid first without question.

Thank you so much for this very informative video. One of the best videos on starter diagnosis.

Brilliant, concise and well explained. Thanks !

This is the best video by far. Thank you for doing these diagrams

This the only video that actually got me to understand. Thank you.

Awesome-very very clear for all levels of technical knowledge. Thank you for your time and effort

Fantastic video that easily explains the electrical system for starter motor.

Lifesaver! I tried to do a swap on my starter today and when the wires came off ... Oops. Forgot how they went. Thanks for the help buddy.

Thank you so much. This helped out a lot. Just changed the starter on my 05 Jeep Liberty and it's still having issues starting but now I know what to look for. Thanks again!

thanks for the video, i never fully understood it all till now, pat

Thank you very much I'm a technician and you helped me to learn more about the starter, it the same on the generators!!

Great video! One of the clearest explanations of voltage drop I have ever seen. Good Job :)

I have watched a lot of videos about the same topic. This one is the best.

great video , simple and clear, helped me a lot when other highly produced videos just confused me. Great job bearing01!

That was very clear to follow. Thank you.

Thank you for making this video. It's been very helpful!!

Excellent session, thank you so much!

TOP CLASS INSTRUCTIONS THANKS FOR POSTING !!

Congratulations on making a brilliant and useful Video. Many thanks.

Thanks for the video, I am having a starter problem. Your video confirms advice I have gotten and consistent narrowing down to two issues for me, battery or dead spot on starter. Being freezing winter days right now, lol, not had a chance to put this to the test but I am confident.

This is a fantastic video. Love your drawings and I'm glad you took the time to spread your knowledge.

Very helpful!!! Excellent information!!!

Great video, clear and well explained. Excellent use of pictures, thanks a lot, hopefully will help me find my issue.

this is one of the best presentations i've ever seen. Excellente!

Great video, helped me troubleshoot my bad starter.

Thank you ! Thank you sir for that outstanding session on troubleshooting.

That was a good video, clear and educational. Well illustrated. Simply great job.

Excellent schematics and explanation. You are a great instructor!

Another “here’s how to do it the HARD way” video!! It amazes me how few people know how to actually use a voltmeter correctly.

Wow! This is the best video on the internet, thank you very much for sharing your knowledge with others, God bless you today and always...

Excellent !! Cant get any better than this ! Neat job

Excellent video! Thanks a lot for your explanation.

This is the best explanation i have ever seen you explained it so easy thank you

Very clear and concise, thank you, it really helped.

Very good explanation!

Excellent Explanation!!!!!!!!!!!!!!!

Excellent video. Everything was explained in language I can understand.

Great schooling, thanks John very good video

That was an excellent video thank you very much !!!

Plain and simple directions great job

I know starting systems and charging systems like the back of my hand and this video is by far the best video I've seen on how the starting system works and how to troubleshoot it. There's only one issue with his drawing of the complete starting system. The "alarm starter disable relay" is not wired that way. There are actually 2 components involved in disabling the starter by means of the car's alarm system. These 2 components are: 1. The starter relay which is shown on his drawing 2. The alarm system control module which isn't shown on his drawing. Inside the relay there is a coil and a switch. Inside the alarm control module there is a "ground" (The alarm control module gets this ground from the negative side of the battery). When you step on the clutch and turn the ignition switch to the start position, 12 volts will not flow through the starter relay coil to ground. Instead, 12 volts will flow through the starter relay coil to the alarm control module, and if everything checks good with respect to the alarm system, the alarm control module will give these 12 volts coming in a ground. This will energize(turn on) the relay and the switch inside of it will close to allow 12V to go to starter solenoid. So if you have an alarm system that controls the starting circuit, this will help you troubleshoot it, and determine if it's the alarm control module or the starter relay. If when troublshooting, you find that the module isn't providing a ground to the starter relay coil, don't automatically think the module is faulty. Before replacing the module, check to make sure the module is getting ground from the battery. You'll have to get a "pinout diagram" of the module to determine which pin feeds ground into the module. If you have a manual transmission you will have a clutch pedal switch, but if you have an automatic transmission you will have a "Park/Neutral Safety Switch" instead. The park/neutral switch is there to prevent you from starting the car in any gear except park and neutral.

Very good tutorial!

Very helpful video, especially your use of the voltmeters on your drawings.

Really great and helpful vid!Thank you!

Great video and clear explanations. Thank you so much making it, really help to understand my Audi A5 starter motor problem.

One of the best explanations Everything was covered Sir

Fantastic, simple and very well explained, much appreciated.

ive watched about fifty videos this is best one yet! yahwey bless you brother fathers real name!

Very good video , easy to understand thanks for the help

This was really useful! Thank you 👍🏻

excellent video. loved that you took the time to draw out a diagram and it is very informative. Thank you!!
