Such an underrated channel, love your morals, work ethic, generosity. Subbed and enabled the bell! Glad to see good people in this world.

Great episode. Cummins swap will be a good thing for that poor old worn out mail truck.

I wish I could find someone close to me that offered a similar service as you with your straight shooter morals.

You do what you do don't worry about negative posts.some people can't comprehend doing nice things for people without expecting something in return.

Finally a good lengthy episode

Good to see you helping people who are likely needing to keep their old cars running.

Sounds like you are a very fair and honest mechanic.

Keep doing what you do and ignore the haters. Some people just want to complain about anything and try to make others as miserable as they are.

Keep the good work. Thanks to you I’m starting my mobile mechanic business .

I do appreciate the fact you don't "disrespect " the brand of vehicle the owner has.

Enjoy the videos thanks for the opportunity. Be safe out there.

Restoring faith in humanity one call out at a time.

I like that you replace those battery terminals for people at no charge! Keep up the good work.

I appreciate you being level headed and even showing what a rough day looks like for you rather than just deleting it. You're a good dude. Keep up the grind.

Nice to have a good honest mechanic working the sreets.

Love how you stand on you own two feet, working and going to school. American Dream

Good job on the key. You saved that dude alot of money. I now it sounds stupid but sometimes we get overwhelmed and might for get to ask if he has another key.

You are the man I work on heavy duty trucks and I work on regular car and trucks also on the side and I’m glad there is still mechanics that are crooked and trying to take advantage of people

Hello, you are what makes this country run.Thank you

I spent 46 years in the automotive repair field, including a stint working as an instructor at Universal Technical Institute. I taught electrical systems, diesel electronics, Air Conditioning, and Transport Refrigeration. I taught a lot of theory as well as practical applications. A lot of guys can add freon to a car without understanding the laws of thermodynamics, and most anyone can replace a blown fuse without understanding Ohms Law. However, understanding the "why" behind what makes a system work goes a long way toward diagnosing and understanding what is not working and why. After watching this video, I wanted to share a little bit that might help you on the next charging system diagnosis. Most (not all) of the automotive batteries being used today still utilize a 6-cell lead-acid or glass mat or gel cell technology. Each of the six cells generally store about 2.0 - 2.1 volts for a standard reading of about 12.0 - 12.6 volts sitting stagnant with no load or charge present. If you just finished charging a battery, it is not uncommon to see it show as much as 2.2 volts per cell for a total of 13.2 volts for a very little while, but after it has a chance to cool down, most good batteries will calm down to about 12.0 - 12.6 volts. Today's electronic voltage regulators are set up so that they detect battery voltage and load at the same time and adjust the magnetic field as necessary in the stator and windings to allow the voltage to go up or down by a few volts as needed to keep up with the load demanded as well as charging the battery back up to normal after starting the car. In the case of jump starting a half-dead battery on a freezing cold day, it is not unusual to see an alternator kick out as much as 14.5 - 15 volts to try to keep up with the demand of keeping the cold engine running and also charging a seriously low battery at the same time. However, it cannot sustain that much of a charge rate for very long or it will boil the battery dry. The regulator has to "see" the battery coming up in voltage as it is charging so that the regulator will start to slowly drop the charge rate to protect the battery while still keeping the engine running. In the case of this vehicle, you had two things working against you: you had a "shorted" battery that read zero volts and probably had an open circuit inside the plates, so that it would never take a charge and retain it. Second, your jumper box was charged to 15 volts and even with it starting the engine and keeping it running, it was still showing in the 14+ voltage range, which your voltage regulator could "see" and was thus trying to "back off" of the charge to bring the battery voltage down some... and there is a good possibility that the car battery literally had a short internally that was causing the engine to die due to robbing the voltage necessary to keep the engine running. Wisely, you replaced the obviously bad battery FIRST, and then re-tested the system. Many shops would have simply installed the alternator, too, and made more money on the job. Like you, I want to do a thorough and comprehensive repair, but I do not believe in selling parts that I am not convinced need to be replaced. I like that you have a Power Probe and know how to use it. I have four of them, along with a plethora of other short-finders and test equipment. Once you understand how and why electrical circuits work, you will find that with a wiring schematic and a Power Probe, there's nothing you can't diagnose. I love electrical because it confuses a lot of people and I find it simple, and for the most part, it is pretty clean work. God bless you and your beautiful family, brother, and keep reaching for the stars. I love your honesty and your work ethic. I hope that this channel makes you enough extra money to help pay the bills and buy the equipment you need. I just subscribed today and will be watching all of your videos. I might even chime in with an occasional suggestion from my 46 years of twisting wrenches. Sometimes you can still learn a few new tricks from an old-timer like me...

Who cares if u upsell battery terms if the car needs it it needs them cant never go wrong replaceing them... Keep up the good work ern!!! Shared to fb

Can we all chip in and get him a new work truck? Great guy👍

Love these long day in the life videos, keep them coming.

Love that you added captions when speaking to your friend and I’m jealous of the Spanish skills

Ernest, that is a Awesome thing you do replacing the terminals for Free Bud!

Set up the ranger with side boxes it’s efficient for what you do especially with your situation, awesome video best of luck with the swap.

I like to help people out as well with little extras done for no charge for people struggling with money at the moment. Good work ethic.

Sweet video and free terminals is a really nice gesture thank you for what you do not many honest people in this world!!

That is cool that you change customers battery terminals for free it's amazing how people want to judge you for the work that you are doing keep doing the great job you're doing helping the people out in your community

I Appreciate your videos as a upcoming mobile mechanic. I’ve learned a lot from your videos.

Those days will happen but stay cool it will get better. Always wish you the best.

You have one of the most interesting channels on KZfaq. Don’t let the trolls get you down. I’m always surprised no matter what channel it is there’s always trolls on them. I always share your channel with my brother-in-law who loves to work on cars. Keep up the great work.

Love that you don't let people get to you. "I do whatever I want" I love it! Lol

Love your videos replacing battery terminals at no charge is another example of a good mechanic/person thanks for the vids

A+ service man, as a fellow mobile mechanic it makes me really happy to see that we still have some mechanics out there that still take pride in what we do.. keeping the customers happy and on the road. Keep up the great work and stay safe out there brother! P.S you'll love the cummins in place of that 6.5

this is really nice from you to change those battery terminals for free...this way it s show how honest you are about little problems like that... it take two minutes to change so... what are you going to charge for that ...nothing... your client will definitely call you back for your honesty ...good men

Great job Earnest!! You're a good hearted person!!

Earnest you are honest and do good work, so even though it is nice to explain that you do not charge to replace battery terminals, as a mobile mechanic, if it needs it, you can charge if you wanted to. A shop would not do that service for free!

Honest Ernest!!! It’s good that you show the good and the bad. If your not able to repair the car because of the faulty wiring for the headlights, you keep it in the video and don’t edit it out. Also with the oil spill LOL proves we are all human 🙏

Your videos have helped me help friends when their cars have problems. It's nice to see how other people diagnose issues.

Nice video liking the lengthy content

You my friend are a god sent I've been waiting for a while. And have fixed my mom's car by watching

Great videos, swapping the terminal for free is a great idea espeically if your not charging. I have seen a lot of comments on it, glad you addressed it.

Thank you for the great videos.. I have learnt so much from watching these videos.. Even tho I'm older I still have learned enough to start doing my own work instead of always hiring someone.. Sorry for the long comment but thank you again and keep up the great videos...

Like the longer videos! Keep up the good work.

New subscriber here, I binge watched for about 5 hours now. It is hard to find someone honest like you these days!

Even a kid watching this video says hey, that's a nice guy. Nice of you to replace terminals

Ernest Great to see that you do the little things for free that build customer loyalty. Rare in a world of unessessary upsell scams. Thanks.

FREE things like what you do with battery terminals- is what brings Customers back. We used to wash & vacuum FREE at my Uncle's Shop, where I got my introduction to wrenching. I was the wash & vac kid! Hand wash with Ivory Snow flakes, Electrolux cannister vacuum. No cost. After engine work, oil changes, tune ups- would all receive a spray of kerosene then hosed off. Showing up with probable parts, and being able to diagnose, AND replace what you need- sets you apart. Knowing, or hypothesis (educated guess) helps to save time- something many of your Customers don't have lots of. A roadside Customer can't order a part and wait. You're not a "parts changer" like some say, while comfortable in their garage, Momma bringing out cookies and warm milk, parts delivered, while the Customer waits or Ubers home. God Bless you, Sir.

Thank you for showing the cars running ! So satisfying

I sure enjoy watching your videos, keep up the excellent work you do and look forward to more great videos in the future!! 👍👍

I really appreciate how thorough you are and the fact that you don’t charge for every single thing you do. I think you look at things from a customer’s Point of view.

Good Day! Love watching guys work! Learn alot from it. 🔨👍😁👍🔧

What a nice guy you are. I’m sure people appreciate you

I’m a mobile mechanic in California. I get it. My vans oil cooler went out on the way to a job and ruined my day. Fight the good fight. Keep moving forward.

Im 17 and I'm starting to work on cars and I love it.

Good idea. I need a new engine in my Ford E350 box truck. If anyone wants to help pay for it, hit me up. lol

North west mobile mechanic, GA.. that battery tester would be a life saver.

Thanks for the translation. It really adds to the video. Sorry to hear about the 6.5 I thought those were pretty good engines and that one was low miles. Great video! I love the "A day in the life." videos!

Your one good mechanic KZfaqr Keep up the hard work I could do with that battery tester mine just broke

Keep doing you and don’t worry about what people say. Good luck on the engine swap

I love the work you do, I’ve been watching since the beginning!

That's a wholesome thing for you to do. Battery terminals are pretty dang cheap, even if you don't buy in bulk. And you're probably going the right route anyway. Any time I've had to clean up my terminals and posts for corrosion, I'd always get more soon, even with felt and goop and using baking soda paste as acid neutralizer. Glad to know that someone isn't marking up services on arbitrary parts. Also commenting to keep your videos up, they disappeared out of my feed for awhile thanks to yt, and I missed out on a month or so... back now, glad to see you're still wrenching!

It is a nice gesture on your part to replace battery terminals as part of a service when they are corroded. Thank you for all you do helping others.

Great Video. It's awesome you go the extra mile and replaced those terminals. I hope I win!!!

Way to go. With that busy day and a long episode never hurts. Great Spanish by the way.

Wish there where more mechanic like you bro keep up the great work

Thats very nice of u to replace battery ends for free...not many mechanics will give anything for free...your a good honest person..keep up the good videos

I appreciate what you do for others.

Your the man fixing battery terminals for free with other work. Hope the truck works out. Sign me up for the load tester.

My wholesome comment. I shared this video to my Snapchat - you’re the man and you’re a great guy. Love the channel!

I just discovered this channel binge watching addicted to it

Sorry you had a rough day but you handle it well! Kudos to you for what you do!

Thatz a good thing u do for ur customer keep up the good work

Its pretty cool that you give out those terminals

Loving ur channel mate. Greetings from Ireland I'm just learning about cars and your channel has taught me a lot. Hope college is going well for you

Just donated. If even 20% of your subscribers donated $1 you'd have your truck back on the road! Hope that it works out for you, brother.

Hey Ernest, I have so much respect for you. I finally did the work and replaced my rear brakes in my 2018 Accord 2.0T...I put it off because of the electronic parking brake. I finally changed them by disconnecting the electronic brake module and decompressing the caliper. First side took me an hour and half, second side took 1/2 hour LOL I have the appreciation of how hard it is to work on cars. I was so sore the next few days but I’m so glad that I was able to do it. Great videos always!!!! Be safe and thanks again for all the informative videos!!

Thank you for always teaching I'm learning a lot wish you the best keep doing what you're doing

You can tell the the attention to detail he has for repairing vehicles he’s awesome 🤩

I died laughing “last time I had my friend change my oil he only put in a little and took the rest!” Hahahahaha

You’re the best Ernest!

Ernest i love watching your videos as you can see im always commenting, I myself am starting mobile mechanic business and am also finishing my level 3 in motor vehicle. I would have to agree with you regarding the terminals. It doesnt cost much and it shows that you care about people :) so just ignore the haters :)

Love the channel dude! cool to see someone who shoots straight with their customers and goes above and beyond by helping with the little things

love your videos man, very humble guy me and my kids love watching you always sharing with my friends and family

Great channel, you are providing a great service for people!

Great information, good content

Really digging your videos! It's always awesome to watch other's methods and diagnostic processes. Major props to you for being so honest while going above and beyond with your services, especially with so many mechanics double dipping and scamming people out there. I also love the fact that you know your limits and are up front to the customer if you aren't sure or aren't comfortable doing something.

Hey Ernest. You’re a good dude. Big fan here. I’m mainly a diyer and like to learn from watching. Thanks for your videos.

Just Subscribed, I look forward to watching more videos. It looks like you do a great service for your community. Keep up the great work! Will be sharing the channel with my son who is just starting to work on his own car.

A Cummins swap would be super cool!!

That guys roommate probably stole his oil and just told him his car leaking lmao

Was just talking with my friends out in Utah about ya! They're up in south jordan, otherwise I'm sure they would love to use your services!

i’ve only been watch this channel for a few months but i’ve learned a lot by the way you do things. Good to see that we still have good hearted people out there who are truly genuine! Keep up the amazing work Ernest!!
