What a great example of how important it is to take an organized and methodical approach to diagnostics! The customer likely has no idea how much money they saved bringing it to you!
I just got burned by removing the switch and testing it out of the car. Yep, works. Put it back in, nope it doesn't work. Went down got a new switch, yep, it triggers much earlier, bought it. Install, and doesn't work. the plate it presses against was the problem. $13 shot to h*ll. That will teach me to remove the seat so I can get up inside the dash with my eyes. LOL At least the dealer felt bad for me, and gave me the $1 pad for free.
@@andrewfidel2220 I had one of those electric lawnmowers and the battery doesn't last long if you are mowing on anything other than level ground. Also, unless you mow often it won't hardly go through tall grass.
@@andrewfidel2220 A few vids back Eric said he had bought himself a battery powered mower, but still pulled out the gas mower every once in a while. I guess every once in a while translates to as often as Eric is shooting a video.
I don't think many people realise the honesty and integrity we see with SMA's videos. I've always loved these essential "rare" qualities in the modern human. Eric and Mrs O, beautiful people
almost every time you start out a video, I swear I hear: "Welcome back to The Self Made Auto Channel." Kinda seems to fit, doesn't it? You didn't get here by dumb luck, gubmint handouts or someone else's hard work. Got lots of admiration for you, sir
That's the problem today. Nobody goes the extra mile. Remaking those grounds just saved that customer from another headache in three months. You're my hero, E.O.!!!
One thing I always appreciate is that both Eric and Ivan tell us "powers and grounds", and both of them always insist on using a known good ground, and likewise a known good power, not trusting the wiring harness until it's been tested. This one is proof positive of that logic and is beyond value as shown.
@@elcomandante9299 If the battery has zero charge, you're perfectly set up to measure resistance from the negative battery terminal to whatever suspected bad ground you're looking at.
Thank you Eric and Ivan for showing me the importance of both good Power and Ground, I recently fixed my Grandsons motor bike, starter dead, had been taken to two local so called professional motor bike repair shops failed to fix it, just wanted to throw parts at it a lot of money he couldn't afford, checked power from the starter button, good checked ground nothing, put in a new ground from the bike frame and off it went, as Ivan would say No Parts Required!! Thanks to you both I was able to diagnose and fix the problem quickly, and the smile on my Grandsons face when he was told his bike was fixed was just priceless....
Well i am here for Eric but Mrs. O is a nice distraction. I'll give you that. I'm a dog person, no cats for me. Besides i am highly allergic to some cats.
I was an hvac technician for 25 years and I trained many new techs right out of school. They never learned dionostic procedure in school, just what things were and basically how they work. I love your videos, you are an amazing tech and teacher.
parts changers.... same with all fields( and college!), everyone wants a quick study and jump out making big bucks $$. it's all coming into a focal point now.
I don’t think I have ever watched a video of yours and not learned something. Your thought process and diagnostic process is second to none. Your golden rule is always the same test and verify. Thanks for all you take the time to show us.
@7:08 when he said "I'm not the best teacher" i had to chuckle. I'm in my 3rd. Year of auto tech school, and i can say without a doubt, i have learned more watching SMA videos than what I've learned in classroom. Give yourself some credit Mr.O
This is not the only example of proving voltage drop you have shown us on many issues and has taught me a valuable lesson on how to track down or eliminate issues before firing the cannon.
My life doesn't require me to have your kind of knowledge of auto repair, but there is a little part of me that wishes I had at least half of your skills. I really enjoy watching your process and seeing how you solve a potentially complex problem. Processes that could be applied to many parts of life, really. Thanks for sharing!
I sometimes watch another channel of someone who says he a car "doctor". When a problem comes in that requires an electrical diagnosis he claims he doesn't have time for it. Yet when I watch South Main Auto, Eric takes in these problems and gets down to pinpointing the eletrical issue or diagnosis and makes it look easy. Tells me that "car doctor" is more like a dr's assistant than anything.
A lot of youtubers became mechanics, detailers, car flippers and doctors in the last period... our hero here is probably the only technician that has close to 1 milion subscribers. I noticed that most of the real technicians don't even get close to 100k. Which is great for me...less ads during the videos 😂. Anyways...a big thank you Eric! You have captivated me for the last 5 years and tough me trics that would have cost thousands in courses. ❤
As an engineer, I can confirm what Eric's saying. ESPECIALLY if you're chasing power problems, always use a known good ground and never assume a provided ground is good.
You are a great instructor Eric.... You take the time to show the proper steps to solve the problem.... not short cut it like some others out there that think they know how to teach....
I'm an electronics hobbyist. I fix stuff, including my own vehicles. My Dad did national service in the Royal Corps of Signals, as a radio repairer. His advice to me, on fault finding was, 'always check your power supplies first'. It has stood me in good stead many times. 'Power and grounds' baby. (BTW. Thanks for the 'solder' pronounciation. Instead of 'sodder'. LOL)
Known good ground and known good power should be compared to the points in question, check them and see if they're what they should be. Assuming they are ok and not checking will go really badly real fast. Good video. Anyone who understands simple circuits can follow you
I want to thank you Eric for sharing your knowledge with us back yard DIY's. The electric steps on my RV quit working and after thinking I was going to have to spend 300.00 dollars on new parts I climbed under the rig and started fishing and found a ground wire with the green crusty puss. Cut the eyelet off and got to clean wire and made the repair like you showed us. Worked great and no money involved except for the new eyelet and heat shrink. Thanks again Eric!!
Content like this should be a "must watch" for any technician program. God knows there's a lot of hacks on RUclips; but Eric and a handful of others are the gold standard.
Fantastic as always, Eric. I still have a mystery bad ground on a friend's 2001 Civic that's causing him problems. Reminded me of that very problem! Thanks as always.
I've listened to several of the skies youtube videos. He is smart intelligent thorough and an excellent mechanic. You should be a automotive teacher.You are in great demand for your knowledge
So, of all the years I’ve been watching your videos, you are a natural teacher. You are entertaining and engaging and if I can understand what you are laying down, anyone can. It seems to be about 60% of the electrical problems you diag are bad grounds 100% of the time!!!
You taught this well. I frequently hear you say something about test but verify. This is a perfect showing as to why. If something doesn't seem right, it probably isn't.
I think the explanation of the diagnosis is of great value. If you don't understand what it means and don't care to educate yourself, well then, it's your lose. If you do, then it is one more knowledge tip in the toolbox.
What ever happened to "test driving" a vehicle after a repair? Kudos to you for that, I repaired all of my trucks and cars for almost fifty years and always took them for a test drive, but almost no one does any more, you are a real professional!
Not the best teacher my foot. Good teaching starts with intimate knowledge of the subject, passion for the subject and, lastly, good communication. You do not have to be slick and polished; just get the point across. You are far better than many I have seen, and I have seen a lot, not just here on you tube. Well Done.
Sure wished you were closer!! Beginning to think it’s worth the trip from GA to New York just to get a solution for my Suburban! Keep posting, definitely a rare breed on troubleshooting and honesty!
very good description of how important it is to sets one potential variable instead of two! i have worked for GM for 35 years and while working on electrical I found this an absolute must!. Well Eric O.
see this is why people come to you to fix their cars because you don't just go by the book. not all codes equal the same fix it method. you are a great teacher we garage techs can learn a lot from your videos. keep up the super awesome videos coming.
Very good lesson as always from you Eric. I've been an electronics tech for as long as I can remember, mostly repairing TV & radio sets before they became disposable. What you teach in this video is priceless and applies to most any type of troubleshooting no matter if the item is a car, boat, plane, TV set, radio, computer monitor, spaceship, or coffee pot ;). Bravo!
It's easy to focus on the component at the end of the wire, and forget that the information that comes from a sensor is only as reliable as the wiring and connectors. And if ground is your reference, make sure that reference is good before relying on it to take measurements. This is quality electrickery content Eric, thank you. And you ARE a great teacher 🎉👍
Brilliant tutorial and diagnosis Eric, if I can understand and I’m far from someone who understands anything auto electrical then you’re a great teacher, top class as ever Eric keep teaching us 😊
Mr O is a automotive genius 👏 this guy is just unreal. I have been watching your videos for over 8 years now and man have I learned alot from you. Thank you Mr O 🙏
Eric, spent many years being a NVH Tech for a couple of Ford dealerships before I moved on to other things, and yes, electronics was never my strong point. You have the ability to teach an old dog the understanding that was lacking in his younger career, thank you son.
Great grounds and parts cannon lesson here. Sitting over 2000 miles away in Mesa AZ while watching, I had to chuckle over "its a real scorcher here today." You should come out here and see the real definition of "indian Summer' Although, maybe the lack of Krusties in the Southwestern automotive wiring harnesses out here have held you back from a summer visit ! Stay cool in the Empire state !

Hold your (parts canon) fire! As Sun Tzu explains in The Art of War, “To subdue the enemy without fighting is the acme of skill.” Well done, Eric. Sun Tzu would approve.
You are a scholar and a gentleman Eric. Whenever you identify something that could save someone headaches and time you take the time to upload a very useful video. You're a Rockstar!!
Retired old fart here, your content is spot on and fun to watch. Nothing like the power of a good known grounds, simple thing like a ground on a trailer plug for instance. Caught many a young tech grounding their test lights to the truck frame rather than the light cord itself with a trailer light flicker complaint. Our fleet hauled gas and other known flammable goods, nothing worse than seeing sparks coming from the truck's 5th wheel and the tankers coupling plate all because the light cord and plug were not checked separately.
Ah yes. Check ground and fluid film after is a motto i've adopted from Eric. A bad ground (rust) was causing my horn relay to blow every couple of months. At first I casually asked some local mechanics what they thought and got blank stares. Then I started tracing wires to find the ground. All I could do at that point was clean and fluid film the grounds for the horn and eliminate that out. Haven't had to change a relay since and that was 8 months ago!!
As much as I love diag and your videos put a new perspective into the way I work and my diagnostics, I would love to occasionally see some videos of you beating the crap out of rust, dealing with broken studs, sweating, doing some timing chains and belts and all that jazz. :D Of course I am well aware you've done all that and then some, I've seen hundreds of SMA videos
You know I've been watching your stuff for several years now and you always say on electrical problem most the time you check the grounds first I hope I understand that and said that right Eric you're the best I really do appreciate what you're doing thank you again for the video
This kind of problem just doesn't happen, down here in North Carolina much except for when someone unloads one of those rust buckets at the car auctions. Great video on how to be sure before you start throwing parts at it.
Thanks for your videos, there's not a lot of honest repair shops and dealerships. You really make the dishonest repair shops and dealerships look as bad as they really are, if only more people would watch your videos there would be a lot more honest technicians. P.s. I particularly liked the video about the suv that was taken to the dealership and the owner was told they needed a complete wiring harness to the tune of $9000. You traced the problem down to a faulty repair of a wire going to the left tail light. I think a lot of problems with technicians is they are taught to rely on only the the car scanner for diagnostic results and when that doesn't work they just assume the car always needs several new parts to solve the problem when in reality you still have to check voltage, ground and other things such as a visual inspections!
Ground side often gets overlooked in electrical diagnosis. I think people just assume it’s ok because it “doesn’t carry any power”. Eric O has a bunch of videos that deal with ground issues. Good job.
As an ex mechanic, and now a mechanical engineer, engineering educator and certified to train the trainer, I can catagorically state, there is nothing with how you explain your logic and the methodical manner in which you get from point A to point B, don't sell yourself short.
This video brings up my situation. I generally do most of my car repairs, at least what I can. I would have plugged my OBDII in and saw the code and loaded the parts cannon. I just don't have the service info and diag tools that you do. Yet you take it in and the tech would probably suggested MAF also. I agree MAF is OEM only. The trouble is parts like that are non-returnable unless defective. You blow the diag, you own the part. Tech at repair shop blows diag, they will bill out new MAF, even though original was working. In my industry, it would be billed out as part of troubleshooting. We only remove parts that we can return or reuse somewhere else. For example we order an $800 controller as that is likely source of trouble, we own it. What is a reasonable service to get wiring diagrams, bulletins, etc?
You`re a very good teacher. Problem for me is forgetting stuff esp. if I`m not working with it frequently. I`ve always had the outlook of not trusting any thing related to electricity. It can get so boring and depressing.
"I'm not the best teacher," says the natural teacher giving another masterclass in auto repair.

Humility goes a long way!!
What a great example of how important it is to take an organized and methodical approach to diagnostics! The customer likely has no idea how much money they saved bringing it to you!
...and by fixing the other two grounds he may have saved the customer from issues with other components down the road.
This kinda thing eventually got me put on hind teat.
Yes, Eric demonstrates a classic technique of going from top down, from the general to the specific. It's the only effective approach.

Ah yes. Check ground and fluid film after is a motto i've adopted from Eric. A bad ground (rust) was causing my horn relay to blow every couple of months. At first I casually asked some local mechanics what they thought and got blank stares. Then I started tracing wires to find the ground. All I could do at that point was clean and fluid film the grounds for the horn and eliminate that out. Haven't had to change a relay since and that was 8 months ago!!
As much as I love diag and your videos put a new perspective into the way I work and my diagnostics, I would love to occasionally see some videos of you beating the crap out of rust, dealing with broken studs, sweating, doing some timing chains and belts and all that jazz. :D Of course I am well aware you've done all that and then some, I've seen hundreds of SMA videos
That’s solder with an L😂 I’m with you on that Eric O. Good stuff.
You know I've been watching your stuff for several years now and you always say on electrical problem most the time you check the grounds first I hope I understand that and said that right Eric you're the best I really do appreciate what you're doing thank you again for the video
This kind of problem just doesn't happen, down here in North Carolina much except for when someone unloads one of those rust buckets at the car auctions. Great video on how to be sure before you start throwing parts at it.
Good work Eric, to actually find the fault has gotta be better than bring backs.
Thanks for your videos, there's not a lot of honest repair shops and dealerships. You really make the dishonest repair shops and dealerships look as bad as they really are, if only more people would watch your videos there would be a lot more honest technicians.
P.s. I particularly liked the video about the suv that was taken to the dealership and the owner was told they needed a complete wiring harness to the tune of $9000. You traced the problem down to a faulty repair of a wire going to the left tail light. I think a lot of problems with technicians is they are taught to rely on only the the car scanner for diagnostic results and when that doesn't work they just assume the car always needs several new parts to solve the problem when in reality you still have to check voltage, ground and other things such as a visual inspections!
9:38 The sadness in his voice as he goes against his own advice and fixes the other grounds even though they are fine - haha 😂
Ground side often gets overlooked in electrical diagnosis. I think people just assume it’s ok because it “doesn’t carry any power”. Eric O has a bunch of videos that deal with ground issues. Good job.
I knew you would fix the other connector because you can't not fix it, it was right there.😂
I have the same addiction.🤪😂🤣🤙
Thanks again for helping me to sharpen my skills in diagnosing electrical issues
If nobody else can do it any better, that makes you "the best teacher," Eric.
As an ex mechanic, and now a mechanical engineer, engineering educator and certified to train the trainer, I can catagorically state, there is nothing with how you explain your logic and the methodical manner in which you get from point A to point B, don't sell yourself short.
This video brings up my situation. I generally do most of my car repairs, at least what I can. I would have plugged my OBDII in and saw the code and loaded the parts cannon. I just don't have the service info and diag tools that you do. Yet you take it in and the tech would probably suggested MAF also. I agree MAF is OEM only. The trouble is parts like that are non-returnable unless defective. You blow the diag, you own the part. Tech at repair shop blows diag, they will bill out new MAF, even though original was working. In my industry, it would be billed out as part of troubleshooting. We only remove parts that we can return or reuse somewhere else. For example we order an $800 controller as that is likely source of trouble, we own it. What is a reasonable service to get wiring diagrams, bulletins, etc?
I didn’t know any better, but thanks to you I now do! Please keep teaching! Newish to scoping.
O man delivers again! There's your problem Lady. One of the only classes I would pay attention in. I will be back after I chase the squirrels. 😜
"I'm not a good teacher!" Says the best teacher this old man has watched on here. Verify, verify, verify!
Thanks!
You`re a very good teacher. Problem for me is forgetting stuff esp. if I`m not working with it frequently. I`ve always had the outlook of not trusting any thing related to electricity. It can get so boring and depressing.
Good job! Clean all three grounds on one service rather than have three visits. In the PRNY you know the other grounds would fail soon.
A Gibbs Rule from SMA? OMG, sheer joy!
Always amazing to watch you think through problems Eric!
