Toyota Rav4: Crank / No Start 

Came from another shop. " Well there's your problem, lady!"

SMA proves that all vehicles can have problems, and the importance of knowing an honest mechanic. True pros over at SMA!

He spent more time with Mrs. O than diagnosing the car 🤣🤣 Respect

Scotty: REV UP YOUR ENGINES!! Mr.O: Hold on a second

Clever fix - well done. Snappy jokes, Mrs O, dogs, lunch, snacks, hunting tales. Another great SMA video.

'The top of the battery looks like a Chia Pet' -sounds like a great idea for next Christmas. Chia Delco.

"I'm gonna go lollygag for a while...drink coffee....flirt with my wife" That's the way ya treat the apprentice! lol

Thank you so much for this chanel, I just started at Mavis and wowed them all by solving a no crank on a bmw, it was a lost ground, they ended up replacing the starter and obviously didn't work. I knew it was something to do with a ground from a past video about voltage drop from you. They didn't trust me because I was a tire Tech or aka a lube tech. I went into the office the next day, told them I can get the bmw started in 5 mins. Got a jumper cable, plugged one onto the battery one onto the engine block and BLAM started. You have no idea how much your videos help me with cars I have and how informative they are, never change, your changing lives that you never met.

this is my favourite auto repair channel

Wow, an actual Mrs. O sighting that lasted more than 10 seconds for a change. Y'all are so funny together.

WoW..The SMA kitchen has really come a long way ! Mrs O's will need to do a kitchen drawer/cabinet tour to satisfy all the people at home & show off the latest & greatest fancy-smancy gadgets from the Bed, Bath & Beyond truck.

Big fan of the channel. I prefer watching your nerdy test light videos over anything on netflix. SMA keeps it 100

By doing the grounds the other shop meant that the battery had a negative cable.

Scotty just threw his cat pillow at the monitor screen.

THE MAN puts his magic on it again. Premature anything is bad, but evidently premature grounding is second on the list.

A shop with a full kitchen and a beautiful chef. You're my new hero.

"My kitchen is three feet wide! No it isn't! It's one, two, three, four.." Stand down brother! This is not our battle to win!

So nice to see an actual honest American with his feet and skillful hands on some solid ground.

As always educational and entertaining. I appreciate watching a professional and honest mechanic applying skill and knowledge to solve a problem. Thanks Mr. O!

Your videos are the best. Learn so much even from ones I have seen before! Thank you for all your hard work and sharing. Watching you diagnose is so informative

I put my local mechanic onto your channel. He has just finished his training and I thought that it would be a great idea for him to learn even more than the basic information.

I can almost hear Scotty spitting all over himself defending his beloved Toyota's honor.

Love watching your problem solving process even though I know very little of how things work. But I'm trying to follow you and learn. Thanks for sharing your knowledge.

Great job as usual Dr. O ! Concise, and direct with no lollygagging.

Your diagnosis was ungrounded. But the repair was well grounded.👍🏻

I'm waiting for a early Geo Metro to show up in Eric's shop just to hear him say "Got a Geo Metro in with the big 1.0 engine".

You're an honest mechanic that knows his stuff. Love your videos

This video encapsulates a well rounded workday - repairing other peoples mistakes, good jabs at fellow employees, excellent food, and great company. All in less than 20 minutes of video time. Good to be the boss! Westin is HUGE. WOW. He’ll be a lot more intimidating than a “this home is protected by Brinks security” sign lol

SMA on a Monday? YES!

Love watching your electrical diagnosis and how to be efficient while doing it. KEEP EM COMING

Your the man Eric, allways good to watch and learn, any apprentice working for you should appreciate your teaching.

My favourite auto repair channel

You always know it's the last one you check because when you find it you stop looking lol

The way you explain the diag process is *money in the pocket*. Thanks Eric!

Eric your the best man, you make fixing cars look so easy. It's always great seeing Mrs.O.

Always a good day when another SMA vidjya comes out! 🤘

I honestly don't think there is a better mechanic on RU-vid than Eric-O . I get on here every weekend hoping to find a another great videos. I like the 1 hour long videos tho. I watch it on my TV so relaxing & educational

Towed from another shop... All you need to know. Let the Dr O do his work!!!!! 👍🔥👍

Your knowledge of vehicles and their sequence of operations are king. Another great job.

I had fun watching this one. Scotty would be proud of you. Please keep making videos.

Took longer to watch then to fix. Love it!!!

Every car owner could only wish to have a shop such as yours to go to. Thanks.

Congratulations on passing the 500,000 subs! You deserve it! Thanks for the video!

Truly honored to watch such a professional at his craft

These diagnosis videos just out a smile on my face. You are seriously so good at diagnosing. Do you have any tips on how I can get better at them? I still struggle diagnosing these kind of issues sometimes.

Jay seems like a man I could be a best friend with.

As always, you're the best automotive circuit debugger on RU-vid.

always good to see Mrs O in a video. The world needs more of her

That reminds me I need to have my fuses done

i work at a private shop with just me and my dad. Your channel really helps me get through some hard spots in my learning. i just finished my 3rd year as an apprentice in Ontario canada, i really wish i could do more electrical diag but my dad is more a chassis guy. we do get some jobs for elecrical diag but with his limited knowledge an my lack of mentorship im stuck teaching myself, and trying to apply what ive leared at school. basically what im trying to say is this channel has so much valuable information for hands on vehicle diag. Really helps wish i had you as a mentor. thanks

That’s a very nice office kitchen. Congratulations on your success in life. I’ve been watching since the beginning and I’ve learned a lot over the years from you. I’d like to say thank you.

Some of the most wholesome content on the internet. Love it.

Love your videos since l retired! Brings my wife and I back when we had our auto repair business! Closed it in 2011.

It's always the last wire, no matter which end you start on :)

SMA! The state of The art when it come to diagnosing automotive problems....thats why I love this channel.....and he's a great guy to boot!💪👍

Eric you never cease to amaze me! I’ve been watching your videos since I was a kid, now I am 75. Har har har! From Texas with love.

Excellent job. You can't assume someone's troubleshooting was thorough or correct. If the shop had checked at the injector they would have known their eyes were lying to them. Chasing your tail can happen real fast.

Eric, out of all the mechanic channels I subscribe to, this one is my favorite. I appreciate your knowledge and have learned lots from your videos. Thanks. Btw I lived just off of "South Main St" in my hometown, so I totally dig your choice in name of your business and channel. Your town/area your from in NY reminds me a lot of Maine. You'd fit in just fine round here. Love your sense of humor and positive outlook. Thanks again Tim.

Your tips about how to start on these troubles are spot on and the results show it. Great find. Keep it Simple. A lot of people go for the

Eric, as you demonstrate , always start with the basics. So many people tend to overlook this and want to go to the most obscure items. Swapping parts or just can't grasp the foundation of electrical systems. I agree with you when you say "If I can do it so can you" it's too bad that most people don't have the basic skills or confidence to even try ! You are a rare person in the trade, skilled, honest and humble. Keep up the good work !

I'm moving to Avoca NY just so I can bring my car here when it breaks. 👍

Always enjoy watching you go through your diag process. "Dr. O"

There is no such thing as a "weak sauce" SMA video! Thanks for making my morning Eric.

Took less time to fix the car than brown the meat.

Im a really good guesser though. 95% of the time I guess it right everytime. If that doesnt fix it blame the parts shop. "Probably a bad batch of alternators from the factory!" its that easy.

Great tips, great diag, great wife, great dogs, great content. Thanks Dr. O!

Apparently "doing" grounds doesn't involve actually fixing them...

"It's shake and bake and we helped!...twins with a southern accent. Even here in Niagara, I remember that commercial!

Love the videos! I always enjoy watching your troubleshooting method.

Awesome video. I ALWAYS learn something, which means it’s valuable to me. THANK YOU!

"We got grounds! We got Mrs. O.! We got another shop that failed miserably and gave Dr. of Motors Mr. O. more money!"

I did cross my fingers for you and it worked lol

You are an awesome teacher. You have taught me alot that i use day to day working on semi trucks. Thank you.

It’s good to see Mrs O again

“didn’t do the grounds long enough, premature with the grounds” 😂

Awesome job. Dam lying shop..lol. Time to eat Mrs. O's cooking. Love your vids. I had a Jeep Wrangler, same problem (no start). Tugged on grounds and they pulled out from eyelet. Repair grounds, starts.

Mr O you are the man. Vid after vid you show in real time that the single most important tool anybody can have is their brain. Many thanks.

THIS IS A COMMENT THAT I MADE TO ANOTHER YOU TUBER THAT HELPED ME TO GET MY VAN RUNNING. YOU ALSO HAVE HELPED ME EMMENSELY WITH YOU VIDEOS AND GOING THROUGH THE PROPER DIAGNOSES BEFORE THROWING PARTS AT IT AND HOPING IT WOULD START. THANKS SO MUCH. ALL THE COMMENTS I READ ABOUT YOU ARE SO GOOD AND HOPE YOU CONTINUE TO ACTUALLY HELP OTHERS. Wow, great info. My 2002 chevy astro had the same symptoms as yours but I started to replace parts instead of diagnosing the problem. When it quit 6 weeks ago I used starter fluid to determine that I had spark and no fuel. So I replaced the fuel pump by cutting a hole in the floor to access it as I had a half tank of gas and no way of raising the van high enough . After that it ran for 6 or 7 days so I could finish a drywall job I was working on. Well it quit again (ruined the old battery by cranking to much so had to put in a new battery) and by watching you tube videos I started to throw parts at it as everyone had the solution. Because the new fuel pump was not working again I brought it back to the auto parts store and they replaced it no questions asked. Great warranty. But because of the end result the original replacement was probably still good. I started with a new coil, a new ignition control module, new crankshaft position sensor , new distributor with cap and rotor. Still no start. Watched more videos and saw that possibly all the grounds needed to be checked. I saw your video but oh well just another none solution so I thought. I was just about to replace the PCM computer as still no results. Then a few days later I saw your video again and remembered what you did. After a very frustrating day yesterday going over everything and then checking with a reliable local mechanic in the afternoon and quizzing him he said he could possibly look at it next week as he was swamped with repairs. Well here we go, I watched your video again and as a last resort what could I loose. Went and got some connecters and opened up the loom of wires just like you did and the rest is history. When i put the key in the ignition and turned it without cranking I had fuel gage now working and now a check engine light. Progress !!! Then went further and cranked it and IT STARTED ! Thank you so much for your knowledge. You saved me from going mad. This van has served me well for the last 15 years and I have been able to do all my own maintenance , but this last 6 weeks was a real challenge. Sorry for the long comment but I am truly grateful to you and thankful that you would share your experience. You have gained a subscriber.

Nice work! Grounds are always sneaky. Back when MTV used to play music, there was a Downtown Julie Brown as a host. Kinda reminded me of that

Great video Eric! I’m just surprised that it didn’t have 4 new ignitions coils in it when you got it haha

I went to the Corning Museum of Glass a few months ago and drove by Avoca. I was super excited that I was at least near a badass garage like yours. I wasn't going to be a weirdo through. Thanks for all the hard work on the videos, Mr. O.

I learn so much from y’all! From a young tech in GA! God bless you!

I wish that dealership service departments would apply logic to electrical issues Then I wouldn’t have to spend endless hours in waiting areas and driving loaners That’s my rant for the evening Lol Excellent work and another good tutorial I don’t like Ricotta either

"And I helped" was Hamburger Helper. I am actually that old! Love the channel Brother.

As always fun to watch. Thank you for the video. It made me smile. Good doggie, nice doggie, love the ears. Eric O goes straight to the problem. Jeez, Eric is a grand master of auto diagnostics.

My Monday evening entertainment with you and Mrs. O!

I would have been here sooner but I was busy watching an old what's up wed :)

even toyotas get murdered by those salty new york roads.

Two things - Jason is a very lucky man training under Eric and - Including Mrs O and some family life makes this so much more than a car fixing channel. Thanks for your work.

"However you do a fuse, I don't know..." My inner 12 year old is laughing his ass off.

Grounds commonly overlooked found usually after parts Cannon is emptied.

Thanks for another excellent video; I like the tip about using a batch cable to make a temporary ground (once a point in the circuit is verified not to have ground) to make sure the connector is able to be grounded. Thx Again

right on south main auto team . Another shop that ran out of magic potions and sent it a real shop . well done . great to see ms. O keeping the team feed and busy , as always. thanks so much eric .

"Downtown Julie Brown" is what I believe you were thinking of

Always great to see you and your family hanging in as a team.

As the son of an honest mechanic long passed, and mechanical myself...your integrity is refreshing. You are clearly living life to the best.

Way to go! My younger brother had a shop and took care of my cars. Cancer took him a few years ago and I still can't find a good shop like yours. BTW lunch looked magnificent you Sir are a lucky man!

Other shop: "Eric, I did everything you said to do in your last video and it still won't start! Help!"

Is the charger ever set on anything BUT nuclear?

Another cool diagnosis and repair video Eric. I'm glad you didn't over think it and end up heading down some rabbit hole.
