i started driving back in 84 and bought my first car in 89 and my first rule was to buy the hanes and/or chiltons book for whatever vehicle i bought. when working on anything, DISCONNECT THE NEGATIVE BATTERY CABLE!!! most times its the first step ion the book for any repair. its there for a good reason.

Gud catch bruh. I was definitely unaware of that fuse bank on the positive terminal circuit. Y'all a funny couple with a great vibe. Don't let the world ever step into y'alls living happy and prosperous.

As a learning young technician i get more knowledge from your videos Great work guys🙏🏿

I really enjoy watching your videos and learning from it. You and your wife do make a good team, and you're a great mechanic. Keep up the good work, and im looking forward to future videos.

You had a good teacher, thanks for passing your knowledge onto the youngsters.

the cat wanted to give a free diag😅😅😅..

When I first clicked on your video and you said 2 battery’s was something to do with a fuse or relay. With two winter vehicles and 2 summer vehicles I started doing research were that’s all I use the internet for. Because everyone man/woman needs to really understand there vehicles. You and uncle Scotty Kilmer are the only 2 I study and I appreciate you. And thanks for the reply to my question on you and your wife’s live yesterday. -26 so guess the polar vortex is over and now the snow begins lol. Thank you once again for teaching your knowledge and I wish you and your wife the best in 2024 💯

Man, I appreciate you man I’ve been out the game for minute now I’m back in the game making money man just because of you and your knowledge. Appreciate you brother.

That was a great repair to show on video nice work…👍👍

That was a smart decision to use a bystander fuse as a test, to prevent your brand new fuse from blowing as a result of a dead short. $140 for the entire fuse bank is an irritating design. Old style fusible links were a lot cheaper than that.

Nice job, Doctor! No tick, that's good. 👌 It was 36 below with 29 mph wind and minus 13 in northwestern Minnesota this morning. 😢Old fat Dutchman loves ya!

Nice work! Good learning moment for me. Electrical stuff always scares me, I don't know nothing about it

them long studs are a good way to cause a short. Those Durango's are nice looking vehicles.

Great diag and repair. I did not know there was a fuse there! (would have seen it when looked there) Not a cheap part! Thanks for the video.

Thank yall for that power circuit hidden path, got it in my private library now.

Very smart diag using old fuse link to check for short. Excellent idea 👍🏻👊🏻

Great video Alex you and your wife do a great job very informative

Do your thing Dr. Alex the car guy👍

Just subbed 👍 keep up the real world scenarios and honesty!

17:45 tell customer to keep original alternator and have it bench tested? As long as that Amazon seller has some warranty on it, I guess it already installed and can't be returned 😅

Good diag video. Snowy and cold here in Roanoke VA

LoL 🤣😆 Putting the engine back in my '03 Forester. Was testing without the alternator connected. Went to hook up the alternator and snap, crackle, Pop. There went the main fuse!! Working tired!

your approach and your wifes enthusiasm to your craft got me to sub

Mopar Goat strikes again 😅 Always informative, keep it up as usual.

Doctor pentastar back again 😍😍 literally watching this vid while at lunch break at my job.

I had a 2018 journey come in a few weeks ago, same symptom... no power. Noticed the ignition switch wasn't lighting up (the off, acc, run). Pulled switch out and found power coming from the underhood fuse box. Checked fuse, and it was good. Pulled up the fuse box to start checking for an open wire and found about 9 wires chewed by a rat. One of them being the power supply to the ignition switch. Soldered back and repaired all damaged wiring, and it was good to go.

You failed to check for parasitic draw. Especially when the customer said she had to change out batteries, or her batteries were dying.

Great job finding the problem keep up the good work nice video my brother

Good fuse info too

I went through the same thing with my 09 Cadillac cts-v, bought a new battery and went through two alternators because the shop said the alternators were the problem, I found out myself theres a wire that went from the alternator starter battery has a fuse on a 200 fuse the wire was hitting my headers and arcing and blew the fuse the fuse is riveted shut so you are forced to buy the whole new I got tired of spending momey so I just cut the fused out and a new fuse holder and put a 250 AMP fuse in it and rerouted the wire awy from the haeders. I only spent $10.00 to fix it myself, I told the shope and they gave half my money and now I have a brand new extra alternator sitting in my garage $380.00. They never knew to check out the wire. I wish you made this video last summer lol. But thanks for your help and the time you put in to making them...

Had this issue twice, main cause was the MOPAR main big battery failing internally.. I have a 2017 WK2… V6 The batter junction fuse box on the positive terminal blew a fuse.. Only solution is to replace box and battery. And all is great, dropped in two AGM batteries VARTA Three years and running strong 💪🏻

Very honest vid. Thanks. Sucks to be the next shop.

awesome work

yo first one love your videos and your energy. you seem like a very nice dude

Alex on the penastar engines . Were do get your lifters and rocker arms from . Keep up the good work. Always a pleasure to see your videos.

Car doctor did it again! 👍💯

NEW SUBSCRIBER and LIKED the videos! A Cat guy has to be cool! LOL I have a 2015 Durango Citadel. I do not have that Aux Battery. What is is for and what Durangos have them? Love the channel! Im a DYI guy and this channel is wicked cool!

EGR cooler on right side, was a recall on the alternator, and their is a flash update for tailgate and sunroof for battery draw.

First time viewer ! Good videos I'll keep watching ,from Charlotte

Awesome repair doc. Man ppl buy the cheapest part for their vehicles, and go cheaper on repair. But be walking around with Jordan's on 🙄 or $200+ pair of shoes.

I love yall man lol Good video

I love your videos, you're teaching me so much. The dishonest mechanics must hate you. Thanks!!!!!!!

Bought my '00 Grand Cherokee few years ago. Cheap. Was having charging issues and battery draining issues. They already threw an alternator at it. The real deal was the plug for the small wires was loose. Tighten them up, solved. The majority of the battery draw was the transistor/relay for the electric fan. Unplug the fan. It also has a mechanical fan which is cooling fine. It still has a battery draw issue. Leave it for 4-7 days and it'll be dead. Don't know what's up. I hooked up a trickle charger. No issues.

I love watching y'all work..The announcer is wonderful..I am coming for you to check the srt8 .06..181k

The cat 😂 good video as always Alex

Secondary battery for the electric water pump, electric oil pump, hydraulic pump(transmission/brakes)….because this thing has auto stop. It’s one of the worst things the automotive industry ever did.

Nice work Alex!!

Please continue Putting thorough detailed Videos on this for Kids that Want to Learn

Man, you got such an interesting channel. I get a kick out of watching you...and still learning at 73. Much Appreciation.

Good job DR.😁😁😁😁😁😁

New subscriber here! Enjoy your channel and awesome info.

Great to know

Good job 😃

Good job

U guys are awesome

Great job and video

Excellent video

Great video!

Wow you a Big Dodge man? You good with hemi V8s

He could have put that secondary battery in Ceres with the main battery overloaded that main lead fuse when it's only probably a 12 only. Very common from idiots doing that in my business practice. So I agree with you doctor

First rule when working on anything electrical on a vehicle disconnect the dam power first before you do anything

good work, a final test would be to turn everything on, headlights, A/C, stereo , windshield wipers, ect , to put a full load on the car.. just to be sure nothing else is overloading the the charging system., never underestimate the problems a person can cause that worked on it before you.. hopefully that elcheapo alternator last a while and they dont bring it back claiming you didnt fix it right,, its always " its the same problem as before". insinuating you didnt fix it right,, if she tried 2 new batteries, after the original battery, there may be a parasitic draw somewhere,, an amp clamp on the main positive battery would be a good test after the system goes to sleep,, around 10 to 40 miliamps would be a ballpark acceptable draw.. if the car comes back in a week or two see if they had any aftermarket newfangled bullshit added, like aftermarket alarm, Gps track your wife devices, ect,,, they are usually the culprit..

That brand is "APremium". They got parts all over Amazon.

AWESOME VIDEO , GREAT JOB,

You should be a Dodge specialist you know a lot about the penastar

Those dodge ipdm boxes are horsepoop. Garbage. My first go to with any electrical issues. Good show sir

Happened to me was working on my car on a Sunday and crossed mounted the terminals blew the main fuze.Soldered it back until the dealership had the part in stock then replaced it

12:15 ugh, proprietary fuse assembly 😢 It's sold online for as little as $84 though, but you need that done ASAP and move along 😅

Harry is searching for rats.🤣🤣🤣🤣. Great work.

Hey Alex on the Penastar 3.6 were do you purchase the camshafts for these engines ? Is there a better price and same quality as the dealer ?

When you said "I'm a cat person"...I subscribed.

Whoever worked on the car before you gets a 'B' for effort & a 'D" for testing & execution. With newer cars you cannot afford a "Oops". That cheap, no-name alternator will cost them more in the long run when someone has to replace it sooner than later. It makes for more business for you!

Nice video.

Did you check if there is a phantom draw? Does that have the TIPM?

For many many Mopar always had a fusible link

Harry wanna drive forgot to tell him it’s dead 😂

Alex what school you attend to become a machanic.You is so smart.

One of those DIY neighbors knows everything mechanic failure lol😅

Hey we have a 2012 dodge Durango and the fan not working and we changed it it still didn't work any idea?

Hey Alex, my 02 Suburban has an extremely loud ticking noise on idle and on acceleration. It has no catalytic converters and has Glasspacks welded in the place of the cats but with very poor quality welds. I also have 3 broken studs on my exhaust manifolds. Does this to you sound like exhaust leak or lifters? I need a second opinion from a shop owner before I remove the heads and check and possibly replace the lifters. I don’t see any metal sparkles when I change my oil. (5.3 Vortec 235,000 miles).

Does this work for my 13Rt Durango !? Because I see that I don’t have that part is not showing fuses

question you said at the start she had draining did u happen to check battery draw after fuse was replaced i just dont see a fuse causing that issue so i am asking i figured someone crossed the terminals and it blew and only being one issue?

Do more videos like this for electric

What's wrong with individual fuses? 🤔

foxy mama the reason that battery rank so high is because they dont cost as much,,, they should be renamed to NEVERSTART because around the one year mark, they quit.. she needs a NAPA OR DURALAST GOLD..

Just think, my '58 Plymouth Suburban, in my profile picture, I believe it doesn't have any fuses!!

Good job , why do you always have to fix janky?

Damn

If they changed the alternator and didn't disconnect the battery what are the odds they touched the ground when they disconnected the battery from the alternator?

👍👍👏👏

They were suppose to swap the old studs from the auxiliary battery to the new one.

What's the purpose of the smaller battery?

Before i watch im gonna guess the TIPM or the battery cover has too much dust as has parasitic drain now or the stop start little battery is draining the main battery.

Wife is on point with the everstart/Walmart brand, but I'd stay with the MAXX series or the platinum (if your vehicle calls for AGM) 4:02 I avoid the middle tier or value battery because it may not have enough CCA for your application

What is the metals touching other metal and that’s why I won’t turn on

Where are you located?

Will yall get the cat a mechanic suit to wear while at work?

Fam im Big Meech third in command,imin th ALT ,il let you service my 2004 Bentley

The thumbnail of you throwing your hands up at the beginning of the video had me cracking up like damn I threw everything at this MF and it still won’t work.

Fam start working on benzs and range rovers, you can charge more😅
