Hyundai SantaFe - Surging Lights? New Alternator & New Battery
ฝัง
- เผยแพร่เมื่อ 28 เม.ย. 2024
- In this video I have a look at a customer's 2008 Hyundai SantaFe that has an issue with a battery draw and the customer states the dash lights and headlights surge when the blower motor is on. This vehicle was already at another shop, and they replaced the alternator and battery. Let this video be a good reminder to not forget the basic checks.
-Enjoy!

A simple ground literally a 20 $40 fix and some yahoo at a different repair shop puts a new alternator and battery in it. Thanks again Mr. O for your patience and honest integrity when it comes to repairing a car.
Unloading the parts cannon is easier than actually caring about your customers and work-quality.
DIY Price - Eric has to make a living - Parts, Diagnostic fee, taxes, Labor, shop supply's = my guess is $150
As a light defense,.... The old battery might actually have gone bad .... because the alternator could not charge it sufficient. Eric did a good job explaining voltage drop! I was secretly expecting a rotten (green puss) flexible engine ground cable and a money-shot. But this one was an acceptable alternative! Good fix.
@@smijas Second defense: the alternator also may have gone bad if this situation had been going on for a while. The surging of the engine points to a (very) heavy intermittent load and that CAN kill an alternator depending on how high the current draw surges.
Ground errors in a car can be time consuming to investigate and some garages simply fire up the parts cannon and don't want to spend the time when that doesn't solve the problem.
@@tjroelsma That's not really a defense. You've just wrapped back around to justifying it not being the shop's problem they didn't do it right despite being paid to fix the problem.
I've been watching your videos for years. Just when I think I've seen it all, you teach me something new. Great job as always Eric!
Never to late to learn!
I was gonna say the same thing!
If he can do it, I can do it? Sounds like an impossibility to me!
It's a miracle that a two thousand and eight hyundai is still on the road.
earths allways stuff up. tight, clean.. more the merryer.. learnt this in the 70,s.
That was a genuinely professional fix. It's what sets you apart from everyone else.
love the use of the nutsert. great idea
Mrs. O is the bright part of Eric’s day. Makes things much better when he is in a fiasco.
Bright part of his life!!
I call my wife my wonder woman because I wonder how she's put up with me for 35+years! Somehow us guys actually find the right lady!
Creepy
Infuriating that you're always the Ringer that's brought in to fix everyone else's mistakes. Everyone else makes the money and you actually fix the problem. Great job as always!
Nah we fix a lot of different things through out the day
I still say you should get the Honest Abe Service Award for Honor and Honesty and Integrity !!!!!
Funny you mentioned this because… the GA (general aviation) YT folks all fly in to the MidWest and pat each other on the backs with awards.
Agree with SMA getting the King Kohuna award for honest, quality service.
While watching this video, I got a feeling that Mr Eric was like a professor in the university, trying his hardest to explain students "how and what", instead of just quickly getting to the cable and move to the next car.( my uneducated opinion). Thank you for the lesson Mr Eric.
I feel smarter every time I watch Professor O.
After 1 year my IQ increased over 150 points.
Me too !
Watching those metal shards flying by the fuse box gave me anxiety. I've learned a lot from your videos. Troubleshooting gold!
It'll be ok ;)
Power was disconnected. As The Professor sadi, it'll be fine.
Shoulda used a magnet to collect them shavings! Otherwise, an outstanding vid.
@@gailtaylor1636How is that relevant?
@@michaelgleason4791 Why was the guy anxious about the metal shards? I'd assumed because he thought they would blow fuses. The shards were blown off BEFORE power was connected. Nothing to worry about.
Reaching for a pocket knife that's not there, and turning on a light switch when the power is out... Such a wonderful feeling
You’re the kind of mechanic everyone hopes they have.
All the hopes and aspirations of this lady ever showing her car in the 2056 Old Westbury Gardens Antique show, dashed by two holes!
😐 Thanks, Eric!
Who else is sparking one up and watching south main auto?
It seems like 90% of charging/starting system problems over the years have been connection issues. Anytime Mrs. O and Andy visit it's a good day!!!!
Mr. & Mrs. O are GREAT together!! The perfect couple. She’s adorable and can hang with your sarcasm and compliments it perfectly!
No-TH-cam Andy needs to visit more often. Love the banter!
Agreed
Did you catch the episode that Eric filmed over at his heavy duty shop in town?
I was a dealership mechanic, (Chevrolet,) and you sir are an excellent mechanic that gives a damn, thank you!
I love it when my mechanic drills a bunch of holes in my car lol. This is one of the best videos I've seen on voltage drops and tracking down bad ground wires. The setup with the new terminals and wiring looks much cleaner with the new gear.
You should watch his older videos, he goes extensively on that subject.
This is the "I understand what the individual electrons are doing" level of troubleshooting. My hat is off to you, sir.
As a general repair shop, you are much better than any brand specific dealer mechanic.
Wednesday night (sunny Aus) watching Eric perform some more mechanic magic!
Great Job Eric! Just did the same troubleshooting for my wifes 91 Lotus Elan. Two seemingly unrelated symptoms, cooling fan doesn't turn on all the time, and idle motor doesn't work all the time. I measured the resistance of the cooling fan switch at the relay panel inside and found the problem. Since it has a rear battery, I used the same jumper cable trick to see if I was on track. Stepped my way from the cooling fan switch towards the battery to find the firewall ground point for the engine was all rusty. Cleaned up firewall and replaced the ground wires. All fixed.
Brilliant video. Old fashioned volt drop diagnosis post to terminal, terminal to cable, cable to contact on body or component. Tip top
Yes sir. Most people do not understand that though
We came for you! A cameo from Mrs. O is nice. I'm a big fan of Astro tools too.
You and Ivan run into these odd grounding issues. But both of you really hit it home with how to diagnose. Great video - very informative.
I'm envious of those two geniuses, my diag skills are lagging in comparison and I've been doing this for years but nowhere near as good as these guys.
I had vibes of Ivans video in this too!
Voltage drop testing is pretty basic 👍🏼
The vast majority of alternator replacement videos, most done by professionals, fail to show any voltage drop testing before they swap in a new alternator. It's a glaring weakness in the way flat rate work flow pushes guys into cutting a corner that literally takes a minute. After a while, guys forget how to do it correctly. I get that new alternators are more tricky because they adjust output based on a more complex algorithm, but diagnosis is the fun part of auto repair. Great demo, Eric!
It's even worse than that. 95% of the guys that own a multimeter or a scanner don't really know how to use them. Don't want to "know" as that requires time to learn. They got fishing or hunting to do.
I used to have a 90s Corolla which due to the NUMMI deal came with a GM alternator. Those things always had the decency to fail completely. I went through several of them. Those Delco alternators were absolute junk new, and even worse when remanufactured! I bought a newer Corolla and first on the list was ensuring it had a Denso alternator...
As an electronics guy, your explanation of voltage drop is spot on. Great job taking a simple problem and showing the thought process.
I like it that you never want to appear to be full of yourself, but don't ever sell yourself short. I follow along with your findings, and start thinking of the next step. But ALWAYS you jump to the most effective test that should come next and it only takes you a split second. Just amazing to watch. And know that this is coming from the guy who was always assigned the tricky jobs where you had to work yourself through step by step. Huge respect for your skills!
There is something to be learned in ALL of these videos which deems them all VALUABLE! Nice job Eric and Mrs O’s appearances and good humor is always a treat.
You make things so simple to see, understand, and learn, Eric. Thank you for the continuing education!
Probably one of my favorite SMA video's. Great explanation on voltage drop and bonus, no bashing GM.
So glad that you covered this subject...the more people that know how to do diagnosis the better :)
Ivan made rocket science out of a loose bolt resulting in a bad ground, you found this without 2 or 3 hours of diagnosis. Well done Eric quick and straight to the problem.
Really good to see true troubleshooting instead of just parts cannon. Always impressed with your skill sir!
You sir are one of the best electrical mechanics I have ever seen.
Amazing job! I bet you just gained a new customer for life.
I could tell that you were in quite the "teachy" mood that day. This was a great video and a fun ride!
No guessing game for SMA and the technician is on top of things, EXCELLENT
Prof. O and his Masters class in voltage drop. This 66 yr old has learned a lot over the years watching your videos. Those who pay attention learn something every day, those who don`t fire the parts cannon....and fail epically. The day I do not learn something will probably be the day I leave this Earth. Well Done Sir.
Saw the title and said push the clutch in. Learned about voltage drop. Great video sir!
Those symptoms were confusing. Good job sorting it out.
What a treat to have Andy make an appearance!
Excellent primer on current/voltage drop/loss!
You do make it look easy but that's years of experience hard at work. Great video Eric O. Thank you.
Such a good repair, better than factory too. CC was giving you applause, at each step, too, esp. before the BIG SQUEEZE!
Thank you SMA. Appreciate your videos. Thank you
Thanks man, appreciate the views :)
I've never ran into this. Love waking up and learning a new thing. Thanks Mr O. Pretty dang cool!!!!!
I always get a ton of info from The (So) Main Man, Eric! Here's a ton of thanks back at ya, brother.
Have the same issue with my Camry and gave up on chasing it down after an alternator and battery replacement. Looks like i have something to do this weekend. Quality content as usual.
That was the absolute easiest explanation on how to test voltage drop I've seen!
Mrs O came out, knowing we needed to see something that isn't old and crusty....lol
Once again YODA, you enlightened a lot of people with your down to earth troubleshooting skills, thank you.
Always amazing Eric!!
I’ve been watching your videos since you fixed an 89 Vette with the same problem as my 89.
Appreciate your honest and intelligent repairs!!!
🎸🎸🎸
Excellent job as always !
Brilliant move, pre-drilling that Fluid Film hole. You're always thinking ahead, Eric!
Hey, I do what I can 😅 🤷♂️
Just when I think I have seen you at your best in another of your videos, you manage to take it to another level. Totally impressed with your skill and ability!
There is value in everyone of your videos. Keep the content and commentary coming thank you
Excellent video SMA!! I get a kick out of how much the neighbor mowes the lawn😅
You would make a great automotive teacher. Awesome job.
Eric is! We are the students. This is my favorite class.
Yes sir.
Now THIS was a great video!!! "Voltage drop" is a thing and it really causes issues that confuse many!!! Great Work on this job!!!
Good job, I always watch your videos, and every time learning something new.
Another excellent video. Great explanation.
Thanks!
You’ve been doing these videos so long that I bet good money that even when you’re not making a video, you still talk out loud and describe what you’re doing. 😀
That's a great diagnostic technique
@@demonknight7965it is actually.
Extremely helpful video. The combination of your logical diagnostic approach coupled with your hands-on practical explanation of what you're doing and what we're seeing makes your videos oh so valuable to us lesser skilled folks. From my experience with training courses, you would be a hugely successful trainer that students would love to experience.
I always enjoy and learn something from watching your videos. Today was an excellent tutorial in how to test ground side voltage drop. You make it easy to understand. As a kid my instructor did not understand how to explain this process. Great job! Great video! A keeper for me.
Great job Eric! Had pretty much the same vehicle in my shop about 18 months ago with the same issue. You found it faster than I did 😂 I ended up repairing the cable end at the factory location but what you did was an excellent repair also. Cheers from Canada!
Puts cable right where Hyundai should have.
Another great diagnosis and repair.. Only wish I was near you.- Great work Eric....!!
As always I always Learn something on every video I love learning everything I can THANK YOU ERIC from the bottom of my HEART !!!!!
Eric has me so convinced everything is wiring, I’ve spent hours trying to prove my BCM isn’t bad, but I’m finally convinced it’s bad.
I've also been watching your videos for a long time, just now subscribed. I appreciate your honesty and wish there was a South Main Auto on every corner in the country. It's hard to keep your auto going strong when you don't know who to trust. I'm on the other side of the country. San Diego county
Excellent video, showing the importance of testing with voltage drop when dealing with charging system issues. So simple, so basic but often missed. Love your videos, love your channel!!
Even so this was a simple fix, it was one of your best videos, learned a ton. Thanks Eric!
Not a dumb video Mr. O, I happen to love voltage drop videos, they’re fascinating imo
Between you and Ivan I’ve learned so much information to help hone my skills. Thank you for showing us and teaching us with your vidjeos.
Just shared this one with my son. 16 and he says he wants to be a mechanic! What a terrific instructional video about voltage drop theory and testing! Thank you Eric!
Great training session...thanks Eric & Mrs. O!
Thanks to you, Mr. O., the terms "frig hole!" and "frig!" have now entered my vocabulary.
It will be nice if we had good honest mechanics like you. That knows what they’re doing.
I have been a parts changer over the years, what you have really open my eyes to is checking wiring, connections, power and grounds. I do appreciate the content you share, thank you.
Great job Eric O!
Voltage drop tests are most often missed, but one of the best procedures to prove a diagnosis.
Keep 'em comin'! 😁👍
You Sir, are like me. A true Mechanic. You find the root cause of the problem, then solve it. We are fast becoming a rare breed, being replaced by "service technicians"!
Excellent work as always, Eric. And God Bless. o7
Also, your friend Andy is quite funny!
Well what do you know! Extensive knowledge plus Shirtloads of practical experience, clear thinking and a good diagnostic technique = Mr Eric O. Brilliant work.
Great video Eric as always. You show the important of voltage drop across in this case Battery Cables. I have learned a lot watching your videos and have been a game change for me on my Diagnostics. Thank you for all you do and Mrs. O.
You never cease to amaze and educate... Thank You!
Hearing a BA technician say "potential difference" made my day. You are one of a kind.
Looking for bad grounds was drilled into us at tech school 35+ years ago. I didn't follow through on that career path but the skills & discipline learned there has been a benefit anyway. Another great video..
Awesome work. Great to see a man take pride in his work. Bravo
I teach 200mv on the ground side and 500mv on the positive side for voltage drops. Great video Eric and this is why I recommend all my students follow you. I also use your youtube videos as a sub plan, when I am out! Keep up the great videos!
I didn’t watch this on account of not having a TH-cam account but I still managed to learn something about voltage drops. Essentially you’re finding resistors in the circuit. Anyway thanks!
I’ve been watching your videos for many years now and you always do a great job for your customers and save them money….I think I’ve been watching for 8-10 years now….enjoy and learn along the way,,thanks
Awesome! Thank you!
You sir are the Einstein of auto repair. Wish you were not so far away from my home in NH.
Voltage drop testing is such an under used and misunderstood tool in diagnostics.
Thanks again for the “real world” use video
Great job Eric.
I learned good information.
Thanks, you always make it entertaining and informative.
Thanks
My Santa Fe had a service bulklketin about this thing. I took the cable off of both ends, cleaned the body ground post and terminals, applied some Tweek , and never a hiccup after. Great job, and great explanations.
Thanks for the refresher course in voltage drop testing bud. It's a simple test that is often overlooked, myself included. Keep the video's coming Eric. 👍👍👍👍👍👍
Not a dumb video. Your “dumb” videos are some of the ones I learn from the most.
Thanks for sharing your knowledge.
Another fine professional fix by the expert Eric.Obviously, the other shop threw the parts cannon at it even now they had no clue.
Tremendous work Eric. Thank you and Mrs. O. Cheers.
Watched pretty-much all SMA videos, all taught me much since the days of Re&Re Engines and Transmissions. I was very-good with Charging system and Electrical problems. This SMA video diagnostic was of a level I've never seen before, hence other Mechanic's send ing SMA electrical problems they cannot diagnose. In that how did you come to decide to bypass Grnd/Plus high amp connections !! ?
So obvious your skills in N/A Auto Diagnostic and Repair are so-far beyond. Your goodness and often hilarious verbal dialogue put's you, in my opinion, the Master Mechanic And the Teacher you've become, Sir. Thank You Eric.
Your are the man. Great teaching. As a DIY, was thinking it was a crappy new alternator. Thanks for the videos.
