BIGGEST Mistake that KILLS ALTERNATORS!!! Dead Battery Current Draw & Alternator Test
HTML-код
- Опубликовано: 5 авг 2024
- This is probably the most common mistake concerning high output alternators and aftermarket car audio batteries. Just like our smartphones, 12v batteries deserve a good CHARGE here and there too!!! Choosing an actual "battery charger" instead of your alternator can really help prolong the life of it. That's because a designated 12v charger provides a safer and more regulated charging environment than a daily driving alternator does. And who knows, hidden under the hood, it could be DUMPING tons of current and potentially causing early FAILURE!!!
Thanks For Supporting :)

Happy Tuesday, Everybody!!!
Thanks For Watching The RUclips Videos!!! :D
EXOcontralto hey I was wondering how many cubes your wall is
@@jonathancosse1155 I think its 17 cubes.
Thanks for making the Vids man it's helped me get more into some of my favorite projects
@@jonathancosse1155 refer to his build video for lil blue I'm sure it's there I don't remember off hand want to say 21cu.ft.
Any recommendations for low budget agm deep cycle battery chargers for batteries like the ones from xs power?

That phone is slowly creeping ist way into the belt drive hahaha
I have anxiety issues now😂😂😂😂😂
Good to know what the unlock code is too ;)
..damn those leaves in there are gonna ignite too.
🤣 Hes going to need a battery and screen for that phone 😂, a new set of ears, and His phone paid Puff Daddy and Mase CAN’T NO BODY HOLD ME DOWN 🤣
It was giving me anxiety

Hey man I really appreciate the time you take to spread your knowledge to us newbies and physically show us how to do things or show how certain things have a real impact on our equipment. Thanks again bro
Wtf this is not get beamed 😆

I get a voltage drop when my radiator fans turn on ....i have a scion xb 240 amp singer 2 hc2400 kinetik double big 0f sky high 1/0 and 2 runs of 1/0 to back battery dont know where to start my voltage is good its just when I'm at idle and the fans turn on my car chokes then levels out
I saw smoke like that coming from my alternator earlier and thinking of what I can do so that it will not quit on me again. I'm just running stock equipment but would like to be prepared.
@@SOBERSCUMBASSHEAD All electric motors such as those on a cooling fan on your radiator draw a lot of current to get moving.. Electric motors usually appear as a short until they start spinning.. A quality motor or one with a decent capacitor to start turning should be available because the standard fans are not very efficient.. Just do a clamp on it and have it turn on, you'll be surprised at the current draw to get them moving..
@@Paul-gz5dp One thing I'd think of if you saw smoke coming from alternator, check the back main connection from your battery.. Sometimes it will ground out on the frame of the alternator and eventually either blow the in-line slo-blow fuse or it will kill your battery or start a fire.. i've seen these go bad and even had one happen in my current vehicle where the alternator was changed and the boot was left off that covers that wire.. after a few bumps, I saw my dash lights flicker like it was losing power and it was.. it was shorted to ground and the wire was melting cause the last guy got the engine from had circumvented the inline fuses and was direct to battery..
If the smoke came from inside, there is not a lot inside a alternator, they are easy to rebuild and most the time, you talking about brushes or diodes gone bad.. High amperage draw like seen in this vehicle will kill the rectifier eventually..
@@neoplasmax thank you I will do that because I am in the process of rebuilding my whole system thank you
I was so pleased when you said "let's get loud" and I had no idea what I was in for. That was just insane. I'm still smiling, can't help it. ..frigging awesome
That’s why I always test electrical systems with the scope with an amp clamp along with checking voltage. Current draw back to the battery should go down quickly after starting. Seen lots of alternators fail shortly after being replaced from weak batteries constantly drawing excessive current. As someone who does this for a living I’m kind of impressed to see you talking about this. Not many people know to look for things like this. Keep spreading the knowledge.
Spot on i repair alternators for a living in england! Have done for the last 10 years! This guy speaks sense!
I love your enthusiasm. It's contagious. Peace my friend
Hey EXO, hope the house issues get resolved in the best way possible for ya. Learned a lot from this vid... Alt was putting out crazy voltage to charge them batt’s!
ExO thank you very informative video , running a old school Orion system with a 240 amp Alternator glad to learn charging the batteries is a positive requirement ,,,respect
i was cracking up when you sped up the video while revving. Legit sounded like mario cart lol
I would have been interesting to see the amp being put out from the alternator after you were hitting all that bass
Amazing video! Super helpful and technically in-depth for something that most of us probably would never think about. Thanks man.
Thank you for this video. So happy to subscribe especially for the landscaping! :) I've learned the hard way to get a 1.5 amp battery maintainer.
Thank you! Excellent Video. I hadn't considered this. I need to get a better clamp meter and measure my own. Nice floating paper man. Thanks for the video.
man your content is amazing. Love your work bud, Thank You.
that's a bummer your new house has a few gremlins in it.... glad to see your still plugging away at the car audio stuff ! cant wait for new vids :)
This was really helpful EXO!! One tends to forget about these essentials like current draw of the alternator, especially when competing in the lanes too
The other thing people will need to know, is that if you have a big audio setup and you're constantly drawing high current from the alternator, you're going to be learning how to yank alternators and put new brushes in em. :) In my case, until I finally just belted up a second alternator, I was rebrushing the main alternator every couple of years. So remember, if you want to go anywhere that having your vehicle quit on you might be kind of dangerous, think about the alternator. I once had an alternator fail on me two hours north of Red Earth, Alberta, way out in the bush on a lease road after driving a friend to a job site. It was -30C in the middle of winter, no cell phones (This was the mid 90's) and the only thing I could think of was to try and limp to Athabasca (I had close friends there that I could stay with). So, as soon as I seen the light come on, I got out and pulled every fuse I could except ignition and even pulled the plug off one of the headlights to cut the current draw in half. I even turned off the cabin blower heater and instead, set the intake to fresh and cracked one of the side windows to "pull" air in through the intake so we at least wouldn't freeze. We made it, but barely. That's like 25 years or more now, but I seem to recall it took us about three to four hours to make it to Athabasca. If I hadn't pulled fuses AND ran on a single headlight, we wouldn't have made it. The one remaining headlight was barely a candle glow by the time we rolled into Athabasca. Before we went in to get a bit of sleep at my friends place, I tried it to see if the starter would turn over. Not even a click. Athabasca is still two and a half hours from home too, so if we'd have pushed for home, we'd have been screwed. Ah, to be young again! :D
Thanks for sharing this info. I've always wondered why I depleted my reserve so quick when I have a 240 amp alternator and a big 3 upgrade! Should be slapping on 14v here real soon!!!
How'd it go
Update
Just wanted to say thank you! You are the reason i bought a PSI platform 2 18. I plan on buying another and build a wall like yours. Love watching all your videos!
Glad to see you're still doing your thing. Love your videos. Well done.
I would have liked to have seen the current draw while that bass was hitting. I am sure they would have been creeping up fast.
Exactly!
Channel Zero One yah I was thinking the same thing
ya i would like to see that too!!!
i would like to see that too!!
Would be nice to see
Awesome bro.i love how straight fwd your vid was. Im gonna charge my batteries right now. How big a alternator do u have in the saturn
I'm glad I watched this video. I just bought a XS power battery charger will definitely be charging my 4 XP 3000s after seeing this. Thanks EXO. 👍👍. Keep up the great work brother. 👍👍
Hey Exo... great vid.... finally a stereo guy posting on RUclips about the realities of Alternator and their relationship to charging batteries.
Well dame I didn't know that .....that news paper was flexing big time you got a lov BASS ...UK England
“DAMN SON WHERE U FIND THIS” 🤣
Very, very, veeeery useful information. Not even thought about my poor battery. Now I have a automatic charger. Perfect.
Really interesting video, this never really occurred to me before I always assumed my alternator was taking care of things.
Bloody hell the flex on them 18s is insane! Great video as always dude. Very educational.
How's learning to weld going?
I had to come back and re-watch and get an example demonstrating the importance of proper periodic charging to a customer of mine so he can make his Singer alt last long as possible. .... Also to note fast forward to 3 years to today and EXO is "EXO the Builder" in his own home! Proof that hard work pays off and things don't always get easier but they do get better! - Congrats on the new house again and the channel is still going up! Thanks for the years of continuing to put out content, been following since you were up North at your Mom and Dad's.
I really enjoy your videos man, keep em coming if you can!
Them 2 18's was chewing up all that paper lol. That badboi was hitting EXO.
Your videos are always informative. Keep it up bro. And im down with some home fix up videos too. Appreciate ya bro.
Thanks Exo! After watching this i figured what was wrong with my voltage drop even with a new aftermarket alternator!
“Nice little system” 😂😂 with big 18s in the back
Been following for Years,,
LMFAO!!, @ 9:53!.. Love your charisma Man. lol, lol...
Love all ur vids man!! Can you put up a video on how to understand the graphing process for designing a box, it would really be helpful breaking down the graph and explaining what we want to see with the fs and hz and dive deep into in to it thanks exo
Love your content EXO! I got my own crescendo build coming up! :D
I also love that you started the video timing portion at 4:20 best time in my book to start any timer lol
Blaze it
LMAO WEED! xDDDDDDDDDDDDDDDDDDDDD LOLOL EPIC.
i would have like to have seen the voltage on the batteries before and after 7 mins of charging. I am not sure how much was due to charging and how much was due to cold batteries.
But nice video
@@4gbmeans4gb61 You can do that but it will hurt the longevity of the batterys. Imagine trying to do work and lift stuff and do things on 2 hour cat naps though out the day. You will become fatigued faster wont have as much energy to use. Verses a full 8hr rest where you have a good full reserve of energy to work and lift stuff. The battery charger is like the 8hr sleep cycle. :)
Hearing Aid manufacturers will be loving you guys in about 10-20 years from now. Better enjoy your music while you can.
Thank you for making such an awesome video on this subject, helps a ton
Exo thank you so much for making these types of bass videos love you brother I appreciate you more than you'll ever possibly know
Man i saw you for the second time on youtube today
I see you on Monday’s and Thursdays on SoundMan Ca RUclips is a small world
I've been preaching about battery chargers/maintainers for a while, I keep a cheap one hooked up to an Optima battery so I can plug it in occasionally over night and on the weekends. It also helps when you don't play your system at high volume all the time and a quality battery or two make a big difference. Happy banging bass bros!
What is a battery charger I can get?
Nice vid bud clicked as fast I could love your vids keep the good / hard work up❤️
Hi exo hows the new door build going I finally found my lay out thanks to your video on your new door speakers I like your second lay out you showed on your video wish you the best bro and happy holidays
So if you drive your car on a daily basis would you still recommend topping off the batteries with a charger?
Absolutely. Even in a regular car without a crazy system. An occasional night on a charger can really help prolong the life of your batteries
YES always help the alt everything will last longer.
@@1970chevy i have the noco charger that can charge a bank of 500amps and it only takes like 3mins to top off my two northstar agm 31s. Currently running 4 runs of 1/0 welding wire front to back and i daily it once ina while i too them off
Definitely - even with a very small system, get yourself a Battery Tender at the least and use it to top off.
With a completely stock car and stock audio system, there is no need to put your car on an external charger. The stock alternator is designed to handle a 100% duty cycle on that configuration, so no.... you're not stressing it out by leaning solely on it.
The only exception to this is if you have a bad battery or you're literally starting the car for extremely short trips with headlights, h/ac blowers, etc running, which don't allow the alt to fully top off the battery to replenish what the starter sucked out of it.
My guess on why his alt is running wide open for so long is that he's continually sucking power out of the battery faster than the alt can return it. And also, he mentioned a lithium ion battery pack he had integrated with his agm auxilliaries and vented plate batt under the hood. If he's running the l/i without a tailored charge controller, then the lithium-ion is probably maxing out what the alternator's voltage regulator will allow because they can drink as hard as they deliver... much faster than the lead/acid based batteries which the car's regulator is designed for. If simply hooked in parallel with the others, it will even act as a buffer, both feeding the other batteries while sucking full-flow on the alternator.
Now there's a chance he's got the li-ion isolated with its own controller, and simply, as I said before, not allowing the alt to catch up.
But this is something you're just not likely to ever have to worry about with a fully stock configuration in your car.
Perfect time to start the counting of minutes on phone.

thank you for replying to my comment yesterday. going to put in quick connector for charger now.
EXO, I love these build videos where you explain everything. I'm a beginner bass head, started with a 10" then 2 12" now I'm working with a 15" and constantly doing upgrades. A big problem I have though is I don't have some equipment like the scope and also I don't know all the technical stuff, Like what volts it's supposed to be at and other things. But I love it and will keep working at it. And I love these videos!
How you doing now Don? 😊
Awesome info like always bro. Man 2 18 in a Saturn!!! Lol wtf your the first I see that. Beast mode bro 👍👊😎
I saw 2 18s in a fiat and that was so loud
One thing and the first thing you need to do to prevent any further damage from happening is to locate and map out the flow of water on your property. I can tell you right now from not seeing anything that if your ceiling is falling in and theres severe foundation damage that somewhere there is a ditch that is stopped up or maybe a channel to direct the water flow has eroded away and is causing water to migrate towards your housepad instead of away from it. the dirt under the house is become saturated and is suppose to be the dryest ...Driest...(however your spell it), part of your property. A house cant sit on mud. Shoot me a message for my contact info if you have any questions or need a second opinion on anything. Youve helped so many of us. I'd be glad to help

Ouch only one like ....lmao
Great video and very informative. Classic EXO. I love it 😁
this is a perfect example that one hobby can positively Impact others. I don't have a stereo except for the stock that came with the truck. I use my truck to power electric chain saws drills using an inverter. I did notice that my alternator gets crazy hot and I wonder if It kind of the same problem. this is good info for anyone. not just stereo people. thank you so much for the info
Your FIRST mistake was going on Facebook to start asking questions.
Just replaced my f150’s alternator. Went from a 95amps to 130 amps
jacob stienecker I’m going from 110 to 270 very soon
Mercury grand marquis 1999 comes with 135 amps stock
Thanks dude. The thought never dawned on me that the easiest way to check the battery charge is to check the alterntor load. Freaking awesome.
Sounds great as usual Exo! You keeping me motivated bro! What's that song you used to demo...gotta try it on my setup...basshead4life!
Yeah. Without a doubt I've tortured my alternator. I bought a new one and having power everything I may be replacing it again if I don't replace my battery. 80% charge or I'm push-starting.
Get a 2nd battery bro
@@DeathLikeWebz I was debating on what battery is going in the trunk. But I just started using a Pioneer 760 and a 12" low end sub. The lights barely dim and I pondered a cap first.
@@MadDragon75 honestly dude I've had a 4 farad capacitor and it did nothing... but when I added a kinetik HC2400 Battery to my system I didn't even notice...it all depends how much current you are pulling.. you can buy a 400 dollar capacitor from XS and it would fix your problem... but that's 400 bucks lol and a 3100D from XS power is what I'll be using from now on
@@MadDragon75 also capacitors work entirely different than batteries, capacitors don't go through a chemical change to deliver current whilst batteries do...and capacitors can deliver power and charge faster... honestly you gotta have both to have an optimal setup
@@DeathLikeWebz yeah. A battery. Your right.
There’s a rectifier you can get for your car so the alternator actually works as a charger👍
What about the rectifier in the alt..
Im not following i guess..
Thanks for sharing this videoEXO. What an amazing subwoofer wall build!!!!!
Great video - Another option is to use a high output (at idle) alternator, for example, Balmar XT-250 with an external regulator that acts like a battery charger. The MC-618 external regulator has charging profiles for different battery chemistries. A normal car alternator without external regulator will definitely have issues exactly as your video demonstrates. A Balmar XT-250 and MC-618 external regulator will provide over 100A at idle and charge the battery properly. I do need to mention I work at Balmar - Thanks!
What Track is EXO bumpin???
Chevy Woods - Gang Shit
Good lookin fam.
The alternator dosnt just charge your battery it powers everything in your car. Most people think the battery powers everything WRONG. The battery is only used to give the spark needed to start the engine once engine is started the serpentine belt moves around the alternator and keeps everything powered. If you turn the engine off then you are using battery power.
WRONG ITS THE OTHER WAY AROUND
Ryan, u r right...
@@grngs1 ryan is right...
The vehicle will run even if there is no battery, but the car wont run if u have a fail alternator...
@@joyetpetero4158 the car will absolutely run with no alternator but only until battery voltage drops too low..cheers.
Wow, no wonder why every six months I needed a new battery. Thnx exo
Had no idea lol thanks for the video bro. And keep them coming.
Hahahahaha!!!! 4:20

Nice info on battery maintenance, it may be useful even for city drivers, ie 5 miles of driving or less on a daily basis.
Hey mang! Love the video. Very informative.
7:58 Just mentality immage cash 💸, not paper.
Monopoly money would be cool too.
Only in America.. No high output alternators, no problems. That's why we don't have that problem in Europe. We usually have only one basic alternator for huge +50kw system. No heat related issues with stock alternators :)
Of course we use +100A chargers in shows with big battery bank. Sometimes idling isn't even allowed :D
in Europe I also see alot of people run Winston's... where half the amount of US lithium runs as good as twice the amount of winston lithium. no space related issues, with HO alts. 😉 in US we run 20k+ systems straight off alts. 😂
@@JoniK1 I watch your videos also, could you explain to me what you mean? You use stock alts?
Yes, you're right. Winston is only affordable lithium on market, same thing in Russia for example. Here's very few cars that even could run multiple alternators, average car has 1-2 liter engine because of emissions. Old car with v8 engine for example is very expensive to keep because of taxes and insurance, even if you don't drive it much :D
Yes, I have two stock 120A alternators for example. There might not be another person with double alternators in Finland. We usually change the biggest alternator available with same fitting, example in my situation: 1.2l stock alt 65A -> 1.6l stock alt with air conditioning 120A. And then we buy battery bank big enough to keep the voltage +12v to get the rated power from amplifiers :)
Great video. Thank you for doing this. Very educational. I know you’re busy but do you fuse between your alternators and batteries under hood?
Exo’s Channel is on my Bucket list
Im not gonna lie I just get in my ride and drive for about 5 mins then i let it rip my system draws more amparage than what my stock alt can produce ...lol its kinda hard to back off on the knob when your getting into the jam. Its funny making heads turn in my city while at a stoplight.

I was thinking the same, seeing that guys ears inches away from his monster subwoofer. :D

@depunkt It will get damaged by the pressure waves created by the subs.

Hey EXO, long time fan of yours. I just recently added a small 20Ah AGM battery and supercapacitor bank to my car (which has a solar setup on it). I've been curious about what my draw was in different situations and if I was getting close to the limit of my 130A alternator at any point, even before I added the extra power sources. I bought a clamp meter not even half an hour before seeing your video and I'm glad that I'm doing the proper checks. Your video highlights how easy it is to assume your alternator will be able to keep up fine, when it's actually being worked to death. I first saw the power draw issue mentioned when I looked up lithium iron phosphate batteries and it's scary how quickly things can go up in smoke if you're severely overloading your alternator at idle. Some newer alternators can change charging current based on temperatures, but most alternators people will come across don't have that protection.
When it comes to adding extra stuff to your vehicle, you need to be extremely careful when it comes to power draw, your wiring, and what is supporting all of the components. If you make a mistake, it can end up with serious consequences such as breaking or severely shortening the life of components, fires/burnt wiring, dead battery in a remote area, etc. Please do your research and don't take shortcuts... shortcuts and lack of research WILL come back to bite you
Another thing, if your current alternator is "just enough" or you're exceeding the amp rating for it in a reasonable scenario, you really should get a higher amperage alternator. It might cost a lot more than a regular one, but it'll be cheaper and far safer for all in the long run
What's up exo love the videos bro, learned a lot about the alternator. What song was that so I can bump it? Keep making great videos!!
Hahaha, guess this dude hasn’t got too many ear drums left after that episode, might be a bit low on brain cells also.
420 😂😂😂 not by coincidence
This is some good info! So glad you made this thank you!
Love the vids. Keep em coming. Bass on bro.
Thanks for the vid. My battery is sitting at 11v before start. Definitely putting a strain on my new H/O alt
Thank you for that information brother! I got 3 battery's and now I know I need to charge them! Would it be better to just disconnect them and charge them with a rolling battery charger?
Cant wait till i can afford my system for my suv. Looks so fun. Thanks exo
Hi nice video, How often you recomend to recharge manually the batterys?? Thanks my system is SQ but is full electrical system and lights.
Wow!!! Love yr channel, thanks for all the info. 👍🏿
I have a 2003 ion with the same engine as yours what brand alternator would you recommend for me
Love your videos keep up the good work .you are a stand up guy
Great video...installing a system in my daughter's car for Christmas..and this good to know..do u have a preferred battery charger I should look in to getting
