Man !!! God bless you sir !!! I was replacing my alternator on my 2007 chevy Tahoe and I completely forgot to disconnect my battery and one of the wires that touched the frame and you know what happened next. Thanks to your video I could find out the location of this fuse, I replaced it and my Tahoe is on its way back to the road, thank you and god bless you!
I am going to do this. My car has been doing this for TOO LONG! 😭😂 PLEASE GOD let this be it! Lol..I have NEVER heard of an Alternator fuse. I've been misled! 😁 Thank You so much Sir! 💝🌹
O'reilly told me there's no such thing as an Alternator fuse, almost one month ago. 😥 My so- called bf is a mechanic & said he'd fix it... again...Ok?! I'm going to do it myself or trade it in. Seems he isnt trying, he certainly isn't impressing me!
I'll call about an inline fuse. Easy enough to fix. Because i did have a new Alternetor installed late last year.I have a 2010 Dodge Avenger. Still a fast car .., I will try this! Thanks so Much! My car doesn't die while driving though.
Thanks for this vid, I think I got my electrical issue figured out. This main alternator fuse had bunch of corrosion and also noticed the right side post that the fuse slides on to was a tad lose, needed a 1/4 turn to snug it back. Buffed off the corrosion, cleaned all the connectors, buttoned it back and been good past few days.
I highly appreciate you brother n my truck been having a delay start like it's not getting the right jump to my battery n thanks bro I'm surely going to start there
Quick tip: in recent GM products, the alternator output may drop as low as 11.5 volts in normal operation. It's a fuel saving feature, the ECU commands the alternator output below the open circuit voltage of the battery in order to stop it from continuing to charge when full. Normally the ECU will detect a faulty alternator and give you a DIC warning, but if you want to check, turn on the headlights. That will cancel the economy mode and kick you back up to the 13s. Ford, Chrysler and some Japanese makes have similar systems, it's because of MPG requirements.
That’s incorrect. If the voltage drops below 11.7 volts GM vehicles go into “battery saver mode” which cuts power to non essentials-air conditioning, charging ports, if it continues to drop then power is cut from stabilitracks, traction control, and eventually power steering. GM vehicles require 12 volts to run properly.
@@wesleypinson1553 Nope, wrong. Straight from the owner's manual on a 2017 Acadia: "The normal battery voltage range is 11.5 to 15.5 volts" From the service documentation, voltage-based idle boost 1 will not occur until battery voltage drops below 11 V as long as the battery temperature is above 5 F. If the BMS does not have a working current sensor, the system will let voltage go down as low as 10 V before idle boost 3.
The manual you are referring applies to a 4 or 6 cylinder engine. We are talking about 5.3 and a 6.2 V8s. Try looking at the correct manual next time. Battery Saver Mode activates under 11.7 volts. A 5.3 or 6.2 will NOT run properly at 11.5 volts.
Just came across your vid in search of Tahoe charging issues. Last year I had to replace both battery and alternator. After doing so, she ran and started up fine. But soon after, the battery light started to flash, and the info center read Battery not Charging. But it still kept starting, and everything was working. I attributed it to and undersized battered.... (Different cca below 700). I also noticed there was a line of some sort coming from firewall and attached to the hood, on driver side. Fast forward to yesterday, I begin having battery issues. Bought a brand new battery, because they wouldn't take old one for warranty because it wasn't dead yet, it still held some sort of charge,( though not enough to crank over motor). Had the auto parts guy check alternator as well, his machine said was good. Bit still the dash reads: Battery not Charging, and the light goes on n off.... Would recommend I perform this inspection of this fuse? Also, the wire attached to hood/firewall, could that be a ground wire? Any help is greatly appreciated, thanks for video, and time.
did u ever figure out what was going on my 06 taho kind of doin same thing i charged the battery for about an hr an it started right turned it off it started right up 2 days later battery dead
@@raymondjohnson8522 no, I am continuing to drive it. Did find out I had a short with the fan switch. But I think in gonna take the alternator back, maybe the voltage regulator is the culprit.... Love my Chevys, but sometimes...🤔🤨it makes me crazy... Good luck with your Tahoe...
Sorry for not seeing this message, Gmail isn't my primary email...this is connected to that platform. Anyhow, no I still haven't figured it out. Since she keeps turning over, I just didn't worry about as I should have. Did change out battery again, 3mo ago. Had AutoZone guy check, they said that my starter is probably the issue, but she starts up fine .. trying to save to get another starter, but until then, I've let it be... Hope you found your issue, again sorry for not keeping up with this entry...
Had battery light on for 2011 Subaru Outback 2.5. Changed alternator and light was still on. Apparently 2 wires were eaten out by rodents which shorted and blew the alternator fuse. Number 10 fuse 7.5 amp.
Honestly parts hardly truly fail n general., Almost always something electrical based which causes the failing parts. Lots of people have no clue how to keep up with their vehicles. Vehicles are like having kids if you truly care, Any type of automotive wires used Oem will dry up and just snap apart after certain amount of years which causes things to run out of Engine timing parameters, and makes things Wear and tear at Extremely faster rate. Vehicles are so simple when kept up with, sooo difficult to play “catch up” on a beat up vehicle tho.
Great video buddy I have a 1987 Chevy Camaro iroc z28 I replaced my steering column and now my battery is not being charged by the alternator properly . I replaced the batter and alternator thinking that was the issue. I haven’t checked that alternator fuse yet will do it tomorrow . I also have an alarm for my car so I have no idea what the hell is going on. But will check the fuse first.
Cool , I have same problem but a 82 280 Zx new battery and alternator . Keeps killing tha battery and show bad alternator. I’m checking this out thank u.
I’d like to add this bit, guys and gals, check the connection points where the cables meet the battery or chassis grounds. I’ve seen rust build up underneath tabs before. Rust and corrosion that can’t be seen by standing over it. My eclipse has this issue and I have to clean it up every couple months, and re-apply dielectric grease.
I have a 2017 terrain and one day my car hesitated to start but that was months ago. Well yesterday it did it again and again so I decided to take it to Auto Zone which they checked the alternator, battery and starter but all was great except the battery wasn’t getting a full charge?? I even took it to a mechanic who ran the same tests and all was good but there was corrosion on the terminals so he cleaned only one side and didn’t take the other one off since there was no visible corrosion. My car started great after that but days later it hesitated again and honestly don’t know what to do when everything is working fine
Hi, I have. 2000 GMC Sierra 1500 with a 5.3 swap 2005 engine, but my battery keeps dying every 2 days if I don’t use it and the volts always drops after a while of using the truck or when I go to reveres and at a red light. I have a new battery and I bought a 2005 alternator but the wiring that this engine has is different than the alternators female port. I bought the alternator that fits that port and it works but it still drains does anyone know if I just need to change the wiring harness back to the original? I also have some electric fans and not sure if that could drain the battery and suck up lots of amps even though on parked the volts stay around 14
I have a 2009 Nissan Murano and have been giving me a hard time going into limp mode where randomly I loose power and acceleration and even let me down a couple times on the road. Read so much about possibilities and replaced intake hose , throttle body and pedal sensor, etc. I didn’t change the alternator as it’s a bigger job and more expensive and I’m afraid in case it doesn’t fix it. Any idea?
@@andrespaz989 yeah it was the voltage regulator in the ecm so I bypassed it and bought a external voltage regulator if you don't want to do that you will have to replace the ecm
@CoastalTexan29 thanks for reply. Will do some research into that. My problem just started out of the blue the other day. Everything was going fine 1 min then I get in, start like normal and instantly notice battery lights on, as well as the lights showing all my doors are open. I cancel my next order and start to head home and 30 seconds later I notice smoke coming from under hood. I pull over and its smoking BAD from what looks like the alternator. And then the battery instantly died, couldn't boost it off or anything, so I towed it home and I replaced alternator as well as the serptine belt and the battery test says its a good battery, but it's still not working. Full charge battery lasts maybe a few minutes and the machine says it's only getting around 2 volts (or amps?) when it should be over 14 from what I was told, but if I Rev engine up it goes up to near 10. Sorry for long reply, just wanted to explain incase you or anyone else who may read this knows of any other possible problems. The guy who put alternator on also used his meter to check if everything's getting power and he said it's showing power going from battery to alternator so I'm stumped, may not even be worth the $ to fix
@@andrespaz989 well I know the ecm or computer is a little expensive but my truck did somewhat the same battery gauge just jumped up showing it was over charging then when I pulled over killed it and the cranked it back up it was fine for about five miles then did it all over again replaced battery and new alternator but since it was my voltage regulator that was bad it wasn't telling my alternator to charge the battery so my battery wouldn't stay charged or the alternator would over charge
Thanks..We've installed new alternator & battery only 8 weeks ago & battery is dead again. We'll have to get it troubleshot I'm guessing maybe needs a fuse? 🤔

Hey thanks for the great advice my man! I'll look into that. Question: before going to the store to buy a new fuse, is it possible to do a continuity test to see if the fuse is still Any good or not?🤔 Thanks again for the great Vid👍😉🇨🇦
@@dannyjohnsonsgarage dude you totally did not help this situation at all , the man asked u a important" key" question & you answer yes without telling him how to??? Really ,.. Wth
@@dewaynebraley2820 the question is answerable by SIMPLE yes or no. Unless you're the one who don't know how to do it then you can simply ask. No insult needed.
Purchased 2 new batteries for 2003 Chevy Silverado HD, each time they are dead in morning. Check engine light is on, Ordered BlueDriver OBD11 which didn’t fit despite calling the company so going to try another’s. Noticed water halfway up inside the front taillight cover, would this short out a battery? I did drain them!
Thank you very much for this video I have a 2004 GMC envoy and There is no inline fuse the only fuse is on the actual fuse Box So I'm trying to figure out if that could be the problem
I bought a used 09’ Hyundai Genesis sedan 4.6 and the 200 amp alternator fuse was blown and someone replaced it with a 100 amp fuse. Could having that smaller fuse cause the alternator to not charge the battery properly? I popped a new battery in and within a day or two it was dead. I’ll be testing alternator tomorrow after the battery recharged, but could t help but wonder if that smaller than it should be fuse had something to do with it. 🤞🏼 Thx in advance!
If I jump the battery wrong and lose all power. My vehicle has the same fuse and is set up the same way but I changed the fuse, got power back to my gauges then turned it on. A few seconds later it died again and full loss of power. Did I do more than blow the fuse what else could it be? Could I have fried my alternator or could the computer be shorting out because I fried that?
Dude you f in brave touching close to all that with the ring on your finger. I was removing a able with an extension on a socket and bumped the crossbraket to the body or frame and thought i blew stuff up and was gonna really mess my self up.
i have a big black wire coming from the back of the alternator screwed on does it go to positive or negative on battery? I have it on negitive and dash gauge for battery shows just a quarter way instead of half way. I put in new battery and the alt but something not right. 99 gmc jimmy.
The video is about locating the fuse. There isn't anything about checking the fuse, as the title states. How do you tell if the fuse is no good? Does it look burnt out in some way as a bad fuse would?
I ran my multimeter from the output of the alternator positive to the negative post on battery and got same readings until the car / (recently jumpstarted) battery died. My question is - before I go a wrangle the alternator, is there a stupid little fuse that manages the voltage regulator on the alternator I should be considering?
My battery charging system came on and so my battery light while driving so long story short I replaced my alternator worked fine for a couple weeks and came back on again so replaced the battery and still getting that message at time my voltage goes as low as 12v but at times goes up to 15v any help ?? I’ll be checking my inline fuse I guess
Well after two reman alternators and a new belt and was still happening after loosing my mind I went and got a $40 dollar used alternator from lkq and that was the end of it no more problems offer that.
@@chuckdiseal6008 hi man man I have the same problem the battery keeps dieing what happens with the ground when I change the new alternator is reading like 12 but is working but two weeks later the battery die again

I have a 1996 F250. Long story short alternator is not charging the battery. Alternator has been tested ok by O'REILLY where it as been bought brand new. Bought a new battery nothing is working. Any ideas?
Danny Johnson's Garage I have a real challenge wanted to see if you can help. I have a 2004 Chevy Avalanche and when I go to turn it over all I get is the clicking. Long story short I replaced the starter, did work. I then replaced my still under warranty battery still didn't work. I thought it may be starter relay but didn't work. I then checked my battery with multimeter while it was running to make sure the alternator was charging. I only got 12.6 volts max. So decided to replace the alternator but it is still not charging my battery and truck won't crank without my jump box. Please help!!!
If the fuse is good, I would also look into grounds. There should be a ground that goes from the engine to the frame and another for the battery to the frame. They can be just as important as the power cable. In the video, It ended up being a bad new alternator, so it happens
@@dannyjohnsonsgarage Thanks for the feedback. Do you happen to know where the alternator fuse is located on a 2004 Avalanche? I will also look into the grounds
@@dannyjohnsonsgarage well after alot of testing and head scratching I finally figure out the problem. It was a bad ground off the negative battery cable going to the frame. I have since added a ground from the negative side battery cable going to the firewall and all is working like it should! Thanks!!
@@dannyjohnsonsgarage Already watched it lol, Debated on going with a 3G wire kit or just upgrading the alternator to one of the better ones. Never planned on running a sound system or anything but I'm not sure what direction to go yet when I get to that mod process
Iv put in 2 alternators in my 2015 Honda Accord sort and still reads 12.5v do you think it could be the fuse. Also battery is brand new so it’s not the battery problem.
ELD (Electronic Load Detector) only allows that car to produce so much voltage. Basically to assist with fuel efficiency and to preserve your alternator's life span. There is a way to bypass it but it can be a tedious task and it is not recommended.
@@LavxaGames it was my battery box(little red box). Mine melted and the connection in the battery box that joined the battery and alternator cables was lost. Bought a battery box and problem was solved.
can't this fuse be tested in some way before I make a trip to the parts store (on foot cause car wont start, cus dead battery cus alternator won't charge)
Its been a while but I think it’s under the cover of the main fuse box in the hood. Take that metal corner brace off (held by 4 bolts) and the entire black case lifts off the fuse box (I think there was 2 or 3 small clips holding it down). Again it’s been a while but I think that’s where it’s hidden on these. But once the cover is off follow the main battery cable to the fuse box and it should take you to it. I think it’s at the top left corner of the box (if your standing at the fender looking at it).
@@dannyjohnsonsgarage ok because I was worried because i took mine out and forgot the original orientation.. having problems with new alternator charging new battery
I have a question i have 2013 chevy impala my alternator cannot charge my batteriy ,i replaced the it about a month and a half ago but the battery has died, when i jump start it regain it power and dies again. Im thinking it might be the fuse, what do you think?.
I am trying to find this on my 2010 Impala and I cant find it! And I cant find anything online to help me locate it. Nothing Google or CZcams has helped me so far. Does anyone know where it is? When you say follow the powerline...do you mean back to the battery?
I have an 05 dmax it says battery not charging so I replaced both batteries and the alternator and it still says battery not charging. The alternator is good I had it tested it will run but stays between 9 and 14 volts I’ve checked all connections I don’t know what else to do. Any idea?
I would check any ground wires that go to the truck. There should be one from the engine to the frame and one from the battery itself to the frame. Also check for any cuts in the wire for the power wire from the alternator to the power supply box with all the fuses
If you look at the battery cable for the positive side it has some built in fuse links. I also show other fuse locations in this video, but I don’t see the alternator since it’s probably the one on the battery cable czcams.com/video/6XxKA0wo_QQ/video.html
I bought a new battery a new alternator but my truck still keeps dying because the battery doesn't charge do you think it's the fuse?? I turn on my truck disconnect the battery and it turns off ....it's on a 1992 toyota pickup
My alternator keeps giving out every 6months or so and its getting annoying because i take it to the store and they test it and say it work’s anyone know what it could be?
It could be a loose or bad ground cable. There are typically 2 From the battery to the frame and from the engine to the frame czcams.com/video/0j6HM11D2dw/video.html
I have a 04 GMC Yukon and upgrade my alternator from 145 to a 220 amp but it's still showing my voltage dropping to almost 10 amps on my dash what can I do to get that higher when i rev it a bit my voltage goes up but at idle or at a light it's low to almost 10. Could it be my fuse aswell and if so we're would it be located at for my vehicle?
I would check the fuse and also upgrade to a larger power and ground wire for anything over 170 amp. It’s called a big 3 wire kit czcams.com/video/0j6HM11D2dw/video.html

How about just an ohms multimeter test from the alternator nut to the disconnected pos. battery terminal end.. If it zeros out you have a good fuse.
Alternators almost never fail, its always the wiring harness, fuses, ground etc etc that breaks first.

Sorry for long reply, just wanted to explain incase you or anyone else who may read this knows of any other possible problems. The guy who put alternator on also used his meter to check if everything's getting power and he said it's showing power going from battery to alternator so I'm stumped, may not even be worth the $ to fix
@@andrespaz989 well I know the ecm or computer is a little expensive but my truck did somewhat the same battery gauge just jumped up showing it was over charging then when I pulled over killed it and the cranked it back up it was fine for about five miles then did it all over again replaced battery and new alternator but since it was my voltage regulator that was bad it wasn't telling my alternator to charge the battery so my battery wouldn't stay charged or the alternator would over charge

Thanks for the video advice can you do one one a GMC envoy alternator
he would have to buy a gmc envoy first tho
I replaced my battery and alternator so light came back on might be the fuse gonna replace it let you know soon
Thanks..We've installed new alternator & battery only 8 weeks ago & battery is dead again. We'll have to get it troubleshot I'm guessing maybe needs a fuse? 🤔
Unfortunately, many new alternators are bad (that’s what happened in the end with this one). Here is a cheap tool to help test it

Good job
Hey thanks for the great advice my man! I'll look into that. Question: before going to the store to buy a new fuse, is it possible to do a continuity test to see if the fuse is still Any good or not?🤔 Thanks again for the great Vid👍😉🇨🇦
Yes 👍🏼
@@dannyjohnsonsgarage dude you totally did not help this situation at all , the man asked u a important" key" question & you answer yes without telling him how to??? Really ,..
Wth
@@dewaynebraley2820 the question is answerable by SIMPLE yes or no.
Unless you're the one who don't know how to do it then you can simply ask. No insult needed.
Do you know where it could be on a Chevy traverse 2011?
Purchased 2 new batteries for 2003 Chevy Silverado HD, each time they are dead in morning. Check engine light is on, Ordered BlueDriver OBD11 which didn’t fit despite calling the company so going to try another’s. Noticed water halfway up inside the front taillight cover, would this short out a battery? I did drain them!
You only need to remove the negative terminal and not both
VERY GOOD VIDEO
Thank you very much for this video I have a 2004 GMC envoy and There is no inline fuse the only fuse is on the actual fuse Box So I'm trying to figure out if that could be the problem
I bought a used 09’ Hyundai Genesis sedan 4.6 and the 200 amp alternator fuse was blown and someone replaced it with a 100 amp fuse. Could having that smaller fuse cause the alternator to not charge the battery properly? I popped a new battery in and within a day or two it was dead. I’ll be testing alternator tomorrow after the battery recharged, but could t help but wonder if that smaller than it should be fuse had something to do with it. 🤞🏼 Thx in advance!
Most likely it’s the alternator’s regulator. A smaller fuse would only chance blowing easier, but it would still work
If I jump the battery wrong and lose all power. My vehicle has the same fuse and is set up the same way but I changed the fuse, got power back to my gauges then turned it on. A few seconds later it died again and full loss of power. Did I do more than blow the fuse what else could it be?
Could I have fried my alternator or could the computer be shorting out because I fried that?
Possibly fried your computer, any update on the fix?
@@_gw33do_ simplest fix. Lose battery cables.
@@SanguineBlackBlood good news 🙏🏼
Dude you f in brave touching close to all that with the ring on your finger. I was removing a able with an extension on a socket and bumped the crossbraket to the body or frame and thought i blew stuff up and was gonna really mess my self up.
i have a big black wire coming from the back of the alternator screwed on does it go to positive or negative on battery? I have it on negitive and dash gauge for battery shows just a quarter way instead of half way. I put in new battery and the alt but something not right. 99 gmc jimmy.
Hello! Could please tell me where is the location of alternator fuse of my 2017 jeep cherokee north. Thank you!
The video is about locating the fuse. There isn't anything about checking the fuse, as the title states.
How do you tell if the fuse is no good? Does it look burnt out in some way as a bad fuse would?
It’s in the video description. czcams.com/video/-BUzm-OeGhE/video.html
Hola tengo una Aspen 2009 y no encuentro el fusible del alternador, sabes donde se encuentra ???
I ran my multimeter from the output of the alternator positive to the negative post on battery and got same readings until the car / (recently jumpstarted) battery died.
My question is - before I go a wrangle the alternator, is there a stupid little fuse that manages the voltage regulator on the alternator I should be considering?
The regulator is within the alternator, so without opening it all up and looking to rebuild the alternator, I’m going to say no
I checked the fuses all still good. Why my new alternator it still not charging. Is there anything else that can help?
Many new alternators are still bad
Great video but I cant find my alternator fuse. Ive misplaced my manual and cant find one online.
Sometimes it’s part of the positive power wire, known as a “fusible link.” It’s not very common to blow out the high amp ones, but it is possible
My battery charging system came on and so my battery light while driving so long story short I replaced my alternator worked fine for a couple weeks and came back on again so replaced the battery and still getting that message at time my voltage goes as low as 12v but at times goes up to 15v any help ?? I’ll be checking my inline fuse I guess
It’s probably another bad alternator (regulator). If the fuse blew it wouldn’t work at all
Loose connection or corrosion at the fuse could be the issue as it was for mine.
Well after two reman alternators and a new belt and was still happening after loosing my mind I went and got a $40 dollar used alternator from lkq and that was the end of it no more problems offer that.
I dont found the fuse in ram 2010 1500 can somebudy tallme where is it?

Danny Johnson's Garage I have a real challenge wanted to see if you can help. I have a 2004 Chevy Avalanche and when I go to turn it over all I get is the clicking. Long story short I replaced the starter, did work. I then replaced my still under warranty battery still didn't work. I thought it may be starter relay but didn't work. I then checked my battery with multimeter while it was running to make sure the alternator was charging. I only got 12.6 volts max. So decided to replace the alternator but it is still not charging my battery and truck won't crank without my jump box. Please help!!!
If the fuse is good, I would also look into grounds. There should be a ground that goes from the engine to the frame and another for the battery to the frame. They can be just as important as the power cable. In the video, It ended up being a bad new alternator, so it happens
@@dannyjohnsonsgarage Thanks for the feedback. Do you happen to know where the alternator fuse is located on a 2004 Avalanche? I will also look into the grounds
@@dannyjohnsonsgarage well after alot of testing and head scratching I finally figure out the problem. It was a bad ground off the negative battery cable going to the frame. I have since added a ground from the negative side battery cable going to the firewall and all is working like it should! Thanks!!

Do i need to replace alternator if the volt 13.9-13.6?
No, only under 13V
Iv put in 2 alternators in my 2015 Honda Accord sort and still reads 12.5v do you think it could be the fuse. Also battery is brand new so it’s not the battery problem.
It could be a fuse or a loose or cut ground or power cable is my thought
Those dont charge until under load
ELD (Electronic Load Detector) only allows that car to produce so much voltage. Basically to assist with fuel efficiency and to preserve your alternator's life span. There is a way to bypass it but it can be a tedious task and it is not recommended.

Where is the 175 A on a 2003 Tahoe? I can’t find it anywhere
Its been a while but I think it’s under the cover of the main fuse box in the hood. Take that metal corner brace off (held by 4 bolts) and the entire black case lifts off the fuse box (I think there was 2 or 3 small clips holding it down). Again it’s been a while but I think that’s where it’s hidden on these. But once the cover is off follow the main battery cable to the fuse box and it should take you to it. I think it’s at the top left corner of the box (if your standing at the fender looking at it).

Hi Danny is there a alternator fuse in all cars. Can't find any in my Suzuki Alto.
Sometimes they have it as an inline fuse built into the actual wire known as a fusible link (google a pic)
Do all cars have that fuse
They do in some form. Some are inside a fuse box, some are part of the cable (called a fusible link) and some are like this with an inline fuse
