a note to take away from this is to become such a good and trusted mechanic that other shops don't only call you to come over they leave you with the hole shop
The Southern Tier of rural Western NY where the only time you lock your car is at church on Sunday morning during Zucchini season so you don't get a seat full. :o)
Yes sir, they just tell you to lock up on the way out :D
South Main Auto Repair : that Would be Quite A Surprise to Hop in Ur Seat in Ur Best Church Suit & Flop Down on ZUCINNI Surprise!! LOL
I am not picking on the typo, because I constantly do the same. But I laughed heartily when I real "the hole shop" I wonder if that wasn't a typo.
@@screamingbeagleproductions1876 if you live in Jamestown you better lockdown everything lol meth heads eveeywhere
Thats a common problem on that vintage vehicle. I never thought about using a head light bulb as an additional tool for a short finder. I learn something from each video i watch of yours.
The field trips like this are cool. That part of the state is quite fortunate to know you and be able to call you.
Ripper vid Mr O. I just love it how the the other 'shops' call on you when they can't find it...
Man, I work at Hyundai and see this all the time, was screaming through the monitor! Good call and great diagnosis!
Wiggle the windshield wiper!! That's my go to diagnostic approach now.
I ordered some stuff off amazon including that Astro 40SL light you use. On the warranty card it asks "how did you hear about us" Obviously, I selected "other" and wrote in South Main Auto on UA-cam....lol
one of the leaders in youre field. together with youre personality. makes you almost addictive
Eric, anything electrical is filled with magic smoke. First rule of electrical and electronic repair is avoid letting the magic smoke out. When you do the system fails and a lot of bad things can start happening in a big hurry. You are on a posting binge. Keep 'em coming.
You are the best guy on UA-cam keep up the hard work
I second that!
Knowing which fuse continues to blow...and then isolating from that point was a big help. But, it's also having those SPECIAL diagnostic tool you have. Nice logical approach to the issue.
The only special diagnostic tool he has is his brain. Everything else can be purchased
You definitely make the distinction between your average mechanic and a technician that can diagnose problems like this. I’m currently in tech school to be a diesel mechanic and I want to be as good as you at diagnosing problems (especially electrical). I love your videos! 👍🏻
Perfect example of a mechanic vs a technician right here.
I was always told "never listen to the last one working on it, he didnt find the problem".
Sometimes a fresh pair of eyes looking at the problem helps out big time. Nice video Eric.
The Plow Guys So true, happened to me at work a few times.
So true, we have all been there
The Plow Guys Been there
I don't think anyone can stay up with you. Your family should be very proud of you. Can't wait to meet you someday. Later Dr. O
Outstanding vid Eric! I'm glad they called you instead of shooting the parts cannon at it! You found the short in under 20 minutes..WOW. You are a diagnostic guru. Shorts are a nightmare..but you make it look easy. You are well respected in the community. 🤘
Dude! The GM dealer has had my 2014 Sierra since Wednesday. They can't figure it out. Need more guys like you.
Shaking my head.
+dpeagles
That's because most techs today are "parts swapers" and not
true diagnostic technicians like Eric O is.
flat rate and rushing is what causes it, like a bunch of drones doing what the "idiot box tells them" good ole computers :)
watershed44 Or in the case of this shop, fuse swappers...oh to have been a fly on the wall to see the red faces when Eric showed them the issue..."there's your problem, lady.... the wires are bare and it let the smoke out..replace that part, put in a new fuse and the smoke shall be contained again"
dpeagles time for a trade to Honda
@@lti134 I bought a tundra in 2017. 👍👍👍
simply the best on the tube. Gawwwd, why can't most techs be like this. diagnosis, diagnosis diagnosis. subscribed :)
Good zoom photography and excellent methodical diagnosis. That circuit breaker is a must for the tool kit----- worth it's weight in gold.
Tom OConnor And fuses.
The EPIC New-Video-Every-Week-Day Series continues. This is my favorite kind of video, the troubleshooting/diag videos. Although I also like the plain ol' maintenance ones. But this diagnostic ones have more of a story to them. I feel like I'm watching an episode of the old House (M.D.) TV show, except with cars instead of people. Solving puzzles is just fun.
If you're good then you don't need to be lucky, and you sir is very good at what you do! Great video and thanks for bring us along.
all that stuff disconnected, and they didn't see bare copper? Questionable methods on their part. Great diag Eric O
Well we all have our days
True, sometimes so easy miss the obvious. usual cause is poor working practice when looking for faults or time restraints and jumping to conclusions rather than spending time on visuals & getting data .
Looks like the whole shop was a giant toolbox lol, so handy having tools lying on floor right next to you lol ...
Did make that one look too easy though . Would assume your 10amp breaker bit more resilient than real fuse looking at those spikes .
Was it bare before the use of the Snap On 10 amp breaker that doesn't open at twice it's rated value. It's like an old school method of bypassing the fuse and watching for the smoke. We used to call it Lucas diagnostics.
Well you know after staring at a project you go blind to things, and so they just was to busy looking at everything else
I think you are too modest with your skill. It's not just luck that leads to a quick diagnosis. As with many fields, there are so many intangibles that come along with diagnostic work, like little details in how something sounds, or when the fuse blows. A lot also comes from experience and, with wire shorts, knowing what places are vulnerable or likely to be problems (like spots where the harness turns a tight corner or passes near an edge). Your skill leads to a quick and accurate diagnosis, not luck. Keep up the good work! This industry needs more technicians like you.
Another day, another Eric O video. My god, you're on fire right now! I'll be sad when I don't get them daily 😂😭
Smokin'!.....
How to fix any car issue:
1) get a diagnosis
2) throw diagnosis in trash
3) take it to SMA
😁
As a pile of fried fuses cascade to the floor..."That looks like frustration."
Priceless.
well it sure does right!?
Thousands of heat cycles from the exhaust manifold broke down that insulation on the crank sensor wiring. Very common problem on the GM 3.1L engine from the early 90's except the crank sensor wiring is on the rear of the engine underneath the exhaust manifold.
Those and the old GM 2.2's with the combo coil pack/IGN module/crank sensor on the backside of the engine under the intake
TrakSpock1 Let's beam down captain.
Wanted to see the look on their faces when you showed them the problem. Thanks for taking us along Eric.
When will your videos ever end? Never I hope, keep em coming Eric
It's amazing to me that most shops lack basic Electrical fundamentals. Kudos Eric O
Brilliant troubleshooting in this video! Cars today rely heavily on advanced buses that are not as easy to troubleshoot as generations before.
Thanks for this video!
they sure do. A lot of networking in cars today
Congrats man!!!! 80K Subscribers...should have 1 million. But we have already spoke about the BS involved in that. I always look forward to your video's more than any other mechanic. Keep up the good work!!
playing away is not the surroundings is the knowledge you have that's pretty cool
I click like before I see your video I know it going to be good!
wiggle test, classic reach around but no brake clean.....Great video. Short, sweet and to the point.
... and all that without using even a toot of brake cleaner! Nice work!
lol can't give a toot in every vid!
that was the best "well there's your problem lady" yet, lol
I'd like to think if you can do it, I can do it but you're being way too modest! Clearly, you can do it but some other mechanics can't even do it haha you're the best!
Niamh Healy yeah working with having Wiring Diagrams, makes troubleshooting a bit easy. Workshop owner neglected this obvious point to see but it happens sometimes.
Thank you Eric O
flat rate work most likely, jam fuses in, look for smoke, sparks or melting and replace that part is what most do :)
He's right though. If he can do it, you can do it. You just need to have the data on hand. If you can't find that data for free, then you are stuck at an obstacle. You can get over the obstacle by paying money for the data of course and knowledge is power.
Basically, you can both do it but Mr.O Has the power in his "pocket" (laptop) and that's what makes it so quick and easy for him.
Technically (for this job) he didn't need any fancy tools. Just a wiring diagram and following the wires. It's not always that obvious but you still CAN find the problem with enough time on your hand.
So in the end, you can both do it but Eric can do it faster, at the expense of having to pay a subscription to various vehicle databases.
Good find and very logical approach to the issue.
Thanks man
Power is nothing without control! Good catch, I'm sure that other shop was going insane over that, critters or failure?
Ever find yourself moving your head around trying to see around brackets and what not while you're watching the video? I hate that. Awesome video though!
That and trying to move the cursor on their laptop...
I find myself seeing a missed problem, and want to comment about it, so they can go back and look at it! But, by the end of the video, it's been fixed, the parts are (somehow) replaced, and the thing I thought I saw was just water (or something) glistening in the over head lighting!
Nice job once again Dr.O! love seeing the diagnoses and sometimes you just can't beat the "ole wiggle" test!
love your videos I am a professional mechanic been doing it for 17 years specializing in German cars and I still learn from your videos great information thank you
Well done Eric, mobile calls to another shop. I think your service area is getting a lot bigger. Thanks for taking us along.
Hi Eric I have the same fuse saver tool I find that the breaker is way more resilient to blow than the fuse it had in the original circuits sometimes it's good but sometimes not what I do sometimes I put a breaker 5 amp less than the original fuse but in your case I bet that if you were diagnosing with the fuse in I bet that you would've had a hard time playing with the wires because the fuse would of blown very quickly it's amazing how many items are supplied power form that one 10 amp fuse.
Great diag Eric o. I totally agree about short testing tools.
Looks like all the smoke got let out of those wires there! The smoke-holding jacket was GONE. :D
I miss that hot front that came through a few days ago - hit 96° over here. I spent a couple years in Phoenix, so I feel right at home in the heat, so long as the dew point is a ways below 70°. I'm out there working in front of the barn with black pants and a black t-shirt, lol. Everyone stops and asks if I'm insane ... :D
46° out there now, and drizzling. Not happy about that! Life in the Northeast - whaddya gonna do ...
Big Nasty arrived the other day, along with my Ajax hammers! Thing is NUTS! The speed at which it hammers is alot slower ... but WOW does she pack a punch! THANKS for clueing us in on that gem - I'll be using that one alot around here. :)
I had the same problem truck kept going into limp mode. Shop refused to look at it without a code. Finally thru a code and I fixed it, great video.
Fantastic lessons in this one Mr. O. Thanks so much for sharing your valuable knowledge!
Well it was a quick easy one but still one we could learn from
u make it look easy!
A pair of pliers on the floor just when you need 'em, that never happens!
As always love to see proper method diagnostics
Many Thanks!
Great video Eric! Nice job finding that in short order.(I honestly didn't notice that pun till I re-read it) As you said, an accurate wiring diagram is key as well as the right tools......some experience doesn't hurt lol. keep up the good work - a lot can be learned on your channel! I enjoy electrical - but without the proper info./resources/tools - its like shooting in the dark. That was an extremely quick diagnosis.
Well some days we get lucky :D
Another "back to basics" solution. This gives me confidence since I only have basic electrical skills and tools.
( I hope you read this) I've been a new subscriber now for about 2 weeks, I've responded a few times on a few videos. Last night (1-21-2018) I put my 9 year daughter to bed at 8pm, well I checked on her (like I do ever night at 8:30) I see that she's under the covers watching you and your family on UA-cam. She loves your puppies and likes you working on cars. She is with me on the weekends if I'm not keeping my home town safe (I'm a police officer) working on airplanes as I'm an A&P IA Airframe and PowerPlant mechanic inspection authorization. Keep the videos coming Mr. O I'm learning alot and so is my daughter lol
Awww how cute :) She may like this one then :) ua-cam.com/video/pNENmVr9ljg/v-deo.html&t or this one : ua-cam.com/video/WgW-qYiaq30/v-deo.html
South Main Auto Repair caught my daughter last night watching those videos when she should have been sleeping and getting ready for school!! AWESOME family video Mr. O!!
2:35 . theres that dreaded doorbell. follows him everywhere like a ghost
What a machine epic work as usual
Great vid. Watched your old vid (2013?) on a MoPar 2.7 water pump while trying to help my son. Big difference in videos from then to now Dr. O. Same quality content. Thank you.
Cool video brother. The wiggle test is a lifesaver sometimes.
HAHA nice diagnosis holy crap how did it run. WOW all bare and broken strands so that baby had to smoke check the insulation...guess that was your smoke. Only a CKP sensor that smoke checked they are lucky. When you said you were wiggling the O2 sensor & the fuel pump was kicking on I started laughing thinking this is different. Well I give kudos to that shop owner they realized their limitations and called you instead of throwing parts at it.
You are awesome. Had the exact same issue for an elderly friend and it was the same crank sensor deteriorated wire harness
When he tossed the pliers back on the floor😂😂😂
Nice quick diagnosis, I hope you charged extra for the blisters! The only time I've had good results with the short finding buzz box is on trailers and buses in long runs where everything is lathered in undercoating, under hood's some luck under dashs useless but a good tool to have at times.
You've got to love the wiggle test. Great video work Eric, keep em coming. Regards Stewart, Australia
I learned the hard way that most vehicles have the o2 sensors tied into the ECU fuse, because I replaced the transmission in my explorer myself, and was lazy about checking for wires touching the exhaust. needless to say the wires were laying on the exhaust and melted through, leaving me dead in the water on the highway haha
oh man bummer!
Nice find On the Completely burnt wires Eric O I been working in a 2000 4runner that keeps blowing the running light 10 amp fuse and I still can't find were the short is been 4 days shorts are not always easy to find the engine bay fuse box on 4runners runs straight into the firewall great video as always Eric O @SouthMainAutoRepairLLC
You rock bud makeing house calls like a real auto dr. Lol.
Eric thank you so much for sharing your method of finding short to ground with us. This was very informative and useful case study. Cheers.
Hello Eric do you have a video of you using a bulb on a short at all time?
Man .....You are absolutely the BEST ....!!!
More patience than a saint ....!! They should show your videos in auto tech schools .... Nothing like working the problem from different angles...
I would definitely drive my car from Scenic Scranton Pa .... for you to repair it .... !!!
Would be a Long ride in Limp Mode ....Lol.... 😁
Eric O this is your best diag vid yet! I will use this method at work, thanks for the lesson sir!
When one gets a low 'Whoa' and or 'Oh!' from Eric midway through the video, one guesses that he has the problem's rough location. Wow this guy is fast, for some one more thorough than lucky.
In my area, this kind of problem should take days or the problem would never be solved ( if it was no bare wire ) Eric you would find this problem even if there was no copper exposed.
The truth is that these guys are not bad but ordinary mechanics and you Eric is a professional with skills way above an ordinary mechanic. I have noticed that some people that have fewer skills than you have 2 million subscribers but you are on your way there and I hope you get there fast.
People help yourself and become a paetron to SMA channel.................
Badass video Eric. I have noticed watching your videos that being an automotive technician is very similar to being an emergency medical technician. If you ever want to get a taste of what I do I'm very certain you would be a great asset. Keep up the great work.
No way man you have to save lives... I just fix junk haha
The "road treatments" cause all this mess! Couple that with the engine's heat, its a recipe for disaster! Just a matter of time.
Finding the problem is worse part, but Mr. O is GOOD at what he does, even in "the field." Thank you for this one.
No video is complete without the classic "there's your problem lady" comment.😁👍
And brake cleaner!
Smoke and a burn. Yup, you found it. Love you diagnostic theories. Thanks for sharing.
A friend would say "I'd rather be lucky than good" but Eric is lucky and good.
Hey Eric, after watching you use your Astro SL40 light every day and how well it appears to perform for you I sprung for one. I'm sure its the most I've ever spent for a small work light but with its features, your comments and the amount of light it puts out, I figured it would be worth it for my old eyes. Got it today and although I wish it was US made, at least it's Taiwan made and not China. It is every bit the quality piece I was expecting and plenty of light for even the "old classic reacharound."
Your awesome at finding the electronic malfunctions Eric. Hats off to ya my friend...
Weathers been crazy. Hit a frost and today its 92. Hell thats 🌞 up tell lunch around here . It should start snowing around 5 that night .
Nice job Eric. Is that circuit breaker custom made or did you buy it?
Nice diagnostic. You are good my friend
There's your problem lady, you've been doin it raw dawg.
Eric your awesome man I love how you go through the diagnosis to see what the issue is
Good wire trace Eric O. That crank sensor cable was toast for sure.
I’ve used a Telcom tool we call a breakdown. It works perfectly when you have a solid short between two primary wire conductors. If your second conductor is the chassis (short to ground) it doesn’t work. The breakdown tool welds the short and then the tone will only travel from the tool to the short and not beyond the short. This is used in cables with hundreds of conductors and is awesome when your affected circuit is miles long. You must remove the “component” at the far end (the customer house In Telcom) then you GIVE HER THE BEANS!!! Weld that short with high voltage and amperage, estimate the distance in ohms to feet, and follow your pickup coil right to it. This would be risky in an automotive application. But hey follow the smoke 😂 I feel like your power-probe tool may have similar limitations and maybe works well if you can isolate two individual wires that are solidly shorted together (less than 10ohms) and connect the two leads to them. I do not recommend applying the weld it together part on a car though 😂
Many times, people forget to think "Keep It Simple Stupid". Eric has a method and he sticks to it. Check Twice, Repair Once.
Once you started the wiggle test it took all of two minutes. "boom". Money in the bank!
wow Eric,you've been shooting out videos faster than the 30 mm gatling on an A10...BRRRRPPP.. another vid...love it
You're so SMART...South Main Auto Repair Technician.
im starting to feel like my dad, my mom says i cant change my trucks shocks, 2 hours later front shocks are changed, mom says i cant change my power window regulator, 30 minutes later my window works.. cant fix... or i fixed it!!! thanks for your videos
Very nicely done Eric :)
Thanks Alan
couple years late to this party, but, damn! you wonder why auto repair shops have bad repS?. in 9 minutes of clock time eric had it localized. and that's after he had to reconnect all the "stuff" the other guys had yanked off? makes me shake my head. sure hope They gained something from this! he sure does light the way!
I checked this video for the speed sensor fuse. Seems you have identified it for me! I think you for that.
I think Hyundai uses sub par materials, rotting control arms, sub-frame, wiring harness, twisted camshaft. i'v seen this a few times with the crankshaft sensor, but it wasn't blowing the fuse, just stalling. good find, great vid.....
BOY AM I GLAD I WORKED ON CARS UP UNTIL 1982, then went to work on heavy equipment till I retired, new stuff too complicated fer this ole wrench, for sure
Few more things to look at in some areas, few less things in other areas. Biggest difference now is you have to be able to read and follow wiring diagrams.
It sounded like you were working in the jungle. Good work Mr. O.
As usual, another great video. Can you tell me the brand name and part number for the circuit breaker tool? Thanks.
that classic reach around seems to come in handy quite a bit,lol,great video as always,have a good one mr o.
