This is why I left auto repair very early! You do great work and you are accused of being a thief! People abuse their cars for year after year and then get upset that something breaks or needs attention! Love cars hate people!

Those battery cable connectors looked like they could have used a good cleaning.

Funny - I had an Exploder once - when it gave me that warning light, I hurried away to a shop. Got told there were problems with MAF and fuel regulator amongst a few others. I also knew I had a bad battery, so had that on order, and got to replace that before anything else got worked on. With the new battery all the other problems solved themselves. This is the fine art of CANbus, which were supposed to make this search for faulty components childs play. Well, it obviously didn't, when it doesn't even take your own power supply into account. On another occasion, I had a Nissan that wouldn't start. Shipped it off to a shop, got bad compression on all four cylinders (2l engine). Changed the battery on that one as well - all readings ok, and started on the first turn. All of this was in Norway, so I hate to say it, Ray - but the faith in automotive repair business is not halting just in the US. I think this is more of a global problem. This is why I think it is so awesome that you make these videos, showing how both good and bad fixes and even some scams could be done. Thanks a lot, dude!

Your a Legend Ray. I showed my wife your vids because I enjoy them so much. She picked up the Rad cap and I thought that was great because I didn't. Glad you didn't forget it. Hope the owners father watch your vid to show that the battery was stuffed. It probably didn't need the alt the previous gut replaced. All the way from Australia 🇦🇺 love your work!

Dad: "You took ADVANTAGE of my daughter by FIXING the problem!!!" Ray: "Sorry about that, I'll revert everything I fixed and install the dead battery so you can get a second opinion from the "mechanic" that stuck their nose in the engine bay the first time and failed to fix anything themselves."

Ten cents it was the dad that did the first wrench throwing in the first place. He’s just pissed that you broke the veil in front of her eyes!

Thanks, simply old guy here. Love your work and your intent. I share in in your joy. Can’t put a price on a craftsman.

Another great video. Never fails to amaze me the amount of codes that dead batteries throw up on modern cars.

Videos like this make me feel like less of an idiot when I do something simple 10 times in a row....Keep up the good work man I really enjoy your videos

Replacing an alternator without testing the battery or even cleaning the posts and clamps, one of my peeves. Hope you sent the link to this video to her father who probably didn't plug in the airflow sensor properly, among a few other failures.

I've watched this one more than once. The battery segment is hilarious.

I love the music on this video! Had me laughing out loud! Great job as always.

Appearing To leave the cap off generated soooo many comments. Great for getting that comment to view ratio up. Good job 👍

After you charged the battery, I was wondering why you put the clamps back on before testing it, lol

It was so refreshing to see a piece of older machinery with more recognizable parts and less plastic and tubes and hoses!!

You only had to LOOK at those battery connectors to see trouble. I can't believe no one cleaned the inside of those connectors, it takes all of 60 seconds with a battery terminal brush. Hint: One of the main things that makes alternators and batteries fail is bad battery connectors!

You're a bad man, Ray! Telling a 21 yo she needs a battery when clearly it was the Explorer that needed it! Well, maybe she does need one....

I saw that cap laying off to the side of the tank when he shut the hood too....rainman will fix it I'm sure!!

You violated a 21yo by providing best possible service? Shame on you for being so professional!

I had the same year Explorer with all the same problems. Finding a excellent automotive technician like Rays is almost impossible.

Loving the dramatic music at the unstable battery pop up......i think i laughed too hard at that!!!

It ain't easy being a mechanic as there are so many dodgy ones out there ripping people off.So when you do good, your work is not appreciated by some. Like all tradies,finding a good,reliable,respectable AND honest one ain't easy.

You know that you're getting old when you watch a video and think, "That's a quality extension cord!" God, what happened - I used to be young and cool!

VERY compelling with a fine soundtrack. TWO THUMBS UP !

Dang, how dare you diagnose and repair the 21yo's when the dad had just repaired it the day before. Haha

Never laughed so hard.. Maybe clean the battery terminal clamps. As them things were corroded on the inside...

Great Production tactics LMAO Love the ending!! Thanks Ray!

Somehow I get the feeling Ray just reeled in a TON of fish with this video. So many caught that cap idea but so many more are ripping him about the way he handled the battery testing. From all of his past videos it is pretty obvious that this HAD to be a gag video. Ray is a far better mechanic than that. As for the girl's father, he should be declared a health hazard not just to his daughter but to everybody she gets near to on the road after he "fixes" things on that vehicle!

Dad wanted something for nothing, wanted it done yesterday, and don't forget unrealistic expectations.

I facepalmed when he put on the battery connectors so he can fail the test again and unplug it once more :D.

“I know this is a lot of work for a free battery test” couldn’t be more truthful.

Love all the AvE references in your videos, between the two of you the entertainment is near endless.

“Taking advantage of a 21 yr old”. I could have sworn that meant you were an adult. Maybe I’m just old fashion…

Those battery terminals could use some cleaning. I've resolved many charging problems by just doing proper battery service (Distilled Water) and cleaning/replacing terminals.

Liked the sound effects, excellent. I was waiting for you to give that Mas Air connection your patented click when you plugged it back in.

Liked the sound effects so much I watch it 7 times.

Enjoyable video. You trolled everyone including yourself. Except the 21 yo daughter. Had a great laugh and thoughts about the content as I have been there myself. Great job.

Yeah the onboard car electronics can cause battery testers to get confused, always best to remove them from circuit.

90% of the time if the alternator has failed it has worked the battery to death its very rare a new alternator is fitted before its killed the battery , its either under charged or overcharged = dead

I love the sound effects...On another note, I was having issues with a 6 month old battery in my 2008 Kia Sportage. No cranky, no lights. I have a dashcam that I have to plug into the cig. lighter and sometimes forget to unplug it. I thought I killed the battery so I hooked my trickle charger to it, it had worked like a charm in the past but the, "charging" light on the charger would NOT come on and the battery wouldn't take a charge. The terminals had next to no corrosion but I had nowhere else to look. Took off the terminal clamp, scraped them out, put some dielectric grease on them and reassembled...voila!

The check engine light didn't turn its self off. Unplugging the battery cleared the codes.

I like Ford but that "Ford Exploder" thing had me cracking up!

Dad mad because HE left MAF unplugged 😆. Love how Ray was OCD to test battery, and tool didn't like the corroded clamps. Win/Win. The battery didn't sound that bad; it was low due to 5000 cranking cycles due to MAF connector causing stalling. Excellent editing 👍.

One look at the battery was all I needed to know... They put in a 90 day warranty battery that was the cheapest one in the store, and then get all upset when it fails.

The call from dad. Definitely my favorite. "Yeah I took advantage of your daughter. In the back seat!!"

LOL I was gonna mention the cap but I’m glad I gave you the benefit of the doubt for 60 seconds! Great channel. You speak my garage language, with such phrases as “test, you ffkin Pisa schitt.” And “son of a...doodle.”

We know the Cap was there because he opened it up and looked in.. It was sitting there.. He's playing with us.. What a damn good mechanic this guy is. He's got the right tools. Good tools make for a good mechanic. good job man.....

I'm old school, I guess, but I would have checked the electrolyte level in the old battery. You will sometimes find the plates partially uncovered which reduces the capacity of the battery. Add distilled water, nothing else.

I like how you had one difficulty on the old lady’s car and replaced her battery terminals immediately, but suffered through “unstable connection” alerts on this one and left the rusted out terminals on. Lol, problem of the day

That was fuuuun to watch 😁👍. Thx for the video dude 🙂

Turned itself off and unhooked battery. I love it!

Well... I changed 2 batteries on a Massey ferguson and removed two shovel full of dirt from the tray since the cover is long gone ... It's a dirty job but someone's gotta do it.. And it doesn't help that the guy who ordered the new batteries got the plus and minus side mixed... Even with pictures of the original batteries

Your battery tester was set to "out of vehicle" instead of "in vehicle". Once you removed the leads it then worked because it matched that tester's settings.

No matter how hard you tried, all I could focus on was the battery label that read: "Warranty: 90 Days"

Hey, on the battery tester...... And sorry if this has been said already but there are over 1500 comments already and I haven't read them all. Each clamp has two separate circuits between the battery and the tester. There are a total of 4 wires, two to positive and two to negative. The opposing jaws of each clamp are an independent circuit. One side of the clamp applies a load to the battery, and the other side measures voltage before, during, and after the load is applied. Each side of each clamp must be gripping the battery post directly and separately. No matter how clean the battery terminal clamps are, this tester won't give accurate readings, or won't work at all if it is clamped onto the battery cable end. It has to be clamped directly on the battery post.

Broooooo they battery tester bit had me stright dying. I am glad to see I am not alone. In b4 DM complains that not enough work orders have battery test slips attached.

Try testing with "In Vehicle" settings selected next time, if it's actually connected to the vehicle.

I just ate at Old Packing house yesterday...! Their burgers are great...!!! Thanks again... Keep up your awesomeness...

Holy cow, those sound effects dude, I was playing project zomboid while watching this and kept looking for the zambie jump scare

If you were going to rip off a young person, it would be a lot more than just a new battery!🤦

Before all the fancy diagnostics, a visual inspection is always a good place to start. The unplugged MAF was a simple fix. Once watched a video where a F150 was in "limp home" mode. The guy checked all the PID's and then got out the voltmeter checking different places on the harness ... until he finally got to the wire that was melted onto the exhaust manifold, shorting and grounding.

You havent made a video yet that I'm not glued too, love the passion you have for what you do

Lmfao my ass over here like "yeah its having electrical gremlins, step 1 new battery" 🤣

I have only watched a few Rainman Ray vids. I think the battery test was part of the free inspection many shops perform for customers. CLEANING CABLES is an extra service. TESTING the battery is part of the inspection. I love all the keyboard warriors who have between zero and a little experience telling Ray that he is wrong, etc. I have been a mechanic from 1970 to 2020. STFU, if you dont know what you are talking about! I, too, saw the cap left off, but I watched to the end. The MAF was fixed in two seconds. I questioned the battery testing, but believe he mad the right call. And, yes, I believe Dad did the lousy alt repair, and left the MAF plug undone. Ray may not be in SMA territory yet, but I think he is plenty capable!!!!

I got the interstate battery tester which worked amazingly built in printer and after every so many tests it would give you a code saying you win a free tshirt or hat and such Was great because I would test every car I touched and give the print out to the customer made them feel better about the service they are paying for

That’s what makes you the man! You don’t give up even when there’s no money in it you still do the morally correct thing! Many mechanics would have simply told the customer they need a new battery and terminals. Then diagnosed the problem if there still was one. I admire that you carry those work ethics. I did the same when I was a woodworker.

"Luv my job so much, I do it seven times!" Cracked me up!

Hmm Ray, the mechanic, taking advantage of a 21 y/o girl, not plugged in all the way, 2 man job...the makings of a porn video...

"How about you fix it yourself dad" Honestly trying to sell someone a battery wouldn't be anything suspicious at all. The suspicious upselling comes when there's a long ass laundry list of shit presented to them and "recommended" they fix it.

I really enjoyed the suspensful 1970's TV show sound effects. I was glued to my seat..lol

That battery totally kicked your ass....funniest thing so far

I'm a firm believer that the engine light went off because you disconnected the battery. There is no way the car cycled enough to clear airflow sensor code on its own without driving for several many miles!

How long till you finally clean the f-in terminals and cables? You must have worked for the government before. Love the channel.

LMAO That wrench light is hilarious 😂

I like all of your videos, before even watching, while the ad is running. 🤙🏻

That battery came from one of those "recycler" type places. They find and resell batteries that are failed but will still kind of hold a charge. Every time I see one and there's any electrical problem, they get sold a new battery first. No test, no questioning, they just get a new one.

Forgot the overflow bottle cap lol nice

seeing that coolant cap next too the tank gave me anxiety and then him questioning the fluid on the ground🤷🏻‍♂️

You didn't do the proper checking process. You completely left the coolant cap off, Priceless!!!!!!

I was yelling "Mass Air Flow Sensor!" as you fought to get it into.the shop. I had mine fail at work on a mk 2 Ford Sierra once. It took so long to get it to my mechanic friend. Had no idea what was causing it to buck & die like that. It must've taken 45 minutes to do the mile or so to his garage. Anyway, I was a sweaty heap when I got there & when he just unplugged a connector & it suddenly ran well enough to use so I could get to the scrappy to get a 2nd hand one it was one of those "WTF!" moments. So, if this ever happens to you. Those symptoms at the start of the video are very idiosyncratic of the MAFS failing. Just unplug it. The car will run well enough to get you gone or to find a MAFS in a scrapyard. It's a fine piece of wire that's heated by it's resistance. It's placed in the air intake & by the amount of cooling that takes place as air rushes past it (it's resistance changes with temperature) the computer can calculate how much air is coming into the intake. This fine wire can break or, more often, get dirty & fail. When you unplug it the computer takes a guess and it'll get you home.

Not gonna lie, I was like Snap-on makes a battery tester? sweet I want one! Than I saw it "work" and quickly recalled why I stopped buying most Snap-on stuff.

3:38 when he pulled the maf sensor plug off 😂 I literally laughed out loud

Over the years I have learned to clean my battery and terminals. A dirty battery will slowly discharge and if you jumpstart it, it’s only a matter of time until it will fail. I had them last over 10 years.

Yes yes, very good scam ray, well done sir! Also I love that you are trolling people with that cap 🤣🤣

I say screw those electronic battery testers and just use a load tester!!!! You'd be done by now. lol

Its amazing what checking connections under the hood can fix....I bet dear ole dad changed the alternator and radiator. As for his complaining..tell him to watch this video...it doesnt lie🙂 Keep up the great work Ray!!

Give him credit his recording , testing a battery 7 times 😅, talking with "us" .we all make mistakes.

Ray is a awesome mechanic i did notice when he closed the hood the antifreeze over fill jug cap was not on i dont know if he took it off or if it came in shop like that ✌

Technically in the video it clearly shows that you closed the hood with the cap still off. So I assume you lifted the hood topped up the coolant and then put the cap on, off camera.

I like it when he says: STAY. Like he is commanding a dog. :)

Awesome snap on battery testor. I'm so glad my el- cheapo one works the first time every time.

Great video to open up a fundamentals of vehicle starting and charging systems class. Ok people, I want you to jot down everything you would do differently if this vehicle ended up in your stall.

HAHAHA The poor tester was set for out of vehicle. The noise from being hooked up caused the fail testing issue.... The main reason I got out of working on cars in the repair shop environment was the customers. Now I do customization work and am able to pick and choose my clients. Yes, I have seen a few mechanics that would try to rip off their own mom and that was the other reason. Lastly I hated working with service writers as most of the time there was communication issues and many service writers can quote specs like horsepower rating but actually know nothing about cars in a way that matters.

I have a suspicion that I’d be concerned about those rusty battery clamp terminals and the none too clean posts too!

I know it's been forever since you put this out but, yes I said, "DUDE, put the radiator cap back on." And then you let me know in a minute LOL.

Those battery testers require a direct to the terminal connection. Without the clamp in between the test lead and the battery terminal

Ever notice that the painted panel just under the rear window is always split on that generation of Exploder? I call it the Explorer butt-crack!

That snapon tester sure makes a hell of a job out of what my Autel 539B does without any issues.

How are so many people complaining about those battery terminals. Have you ever seen corroded battery terminals? These are perfectly fine in the video.

I love it when 'professional Mechanics' miss the obvious. Those battery connectors were rusted/and filthy dirty. A hit with a brush, between the post and connectors would have given you the fail a lot quicker. Yes, trouble shooting the Electrical system should have been done by the person who charged them for the alternator replacement, and the Radiator repair was half way done. I would have (as I do with my clients) told them, "the person who replaced the Alternator left a sensor un-plugged. Did they check the battery, after changing the Alternator? I know they checked it prior, but if they came up with the Alternator being bad, depending on the tester they used, the battery was not checked correctly."
