Been watching your videos. Thank you for taking your time to make them for us! I do have a question. I have a 2014 Honda accord LX 100,800+ miles. I just replaced the battery two weeks ago, then the alternator the next day. Ever since I’ve had the car back, when i am stopped at a red light it idles rough and acts like it wants to lose power. Acceleration seems off and then the “check charge system” indicator will flash on my dash. I have had it tested at AutoZone and it came back with a bad reading. O’Rileys today said it was a bad voltage regulator. But I have taken it back to the same mechanic twice, and each time he says there’s nothing wrong. Could it be the alternator? I have changed the spark plugs. Coils are fine too.
If u out in after marker alternator then u need to redue the alternator. Put in original alternator check sensor on battery and horn fuse as well
Been following your video a long time. Thanks boss. I have a question. My battery doesn’t go beyond 12.70 when car is on. But when I turn on full head lamp or Acc, it goes to 13 to 14 volt. But when I turn of the load, the voltage drops to 12.6 which isn’t good. What can be the issue pls ?
So my accord only change at 14.** volts when the highlights are on. Highlights off its at 12.**volts. Is this normal for these model?
Yeah I noticed that it cuts down power if ur not using accessories or putting out load
I have a 2105 Accord. Should my battery read 14.4v as soon as I turn the car over? It seems it takes a little drive before it gets to 14.4v. The alternator puts out 14.4v when I start the car.
Nope it should rear 14.4v usully it work off 12 v this system is different than older modes of cars
Bro please help! My 2015 Honda Accord stays at 12v most of the time till charging system kicks in. Is there anyway i can keep it at 14v + at all time? I need constant 14v always because of my radio system. Did i burn a fuse or something? Please help me.
No it will give u check charging but not sure these alternator are like smart controlled alternator
Great video
What brand besides oem would you recommend? They only offer Bosch and pure energy out here
I use remy
What about the electronic battery sensor ? Will you always get 14.5 Volt charging voltage ? or will it sometime drop to 12.7 V ?
Yes it will drop
@@RBTheMechanicUsing my Konwei battery tester per their instructions on a Honda accord 2015 shows charging voltage to be about 12.68 V. I thought the charging system was defective. So I guess not
@@RBTheMechanic You learn something new every day. Just when you thought you knew all about charging voltages
I have a 2016 honda accord sport i was noticing my light’s getting brighter when i revved the engine. I brought it to autozone and the test came back saying current flow fail for my charging system. They said it was the alternator, what is your opinion on this ?
I think so alternator as well
mines be at 12.3 but when I turn my lights on it goes up to 13 plus .. What do that mean?
Normal
I have accord 2017 While the car is running 12v What is the problem supposed to be 13 to 14 volts?
13+ volts
@@RBTheMechanic My car only has 12 what's the problem
@@Y4SOORE alternator
@@RBTheMechanic Can it be fixed?
@@Y4SOORE alternator need replacement original

I found the same issue on sum of these accords did u replace ur alternator?
No I didn’t, the alternator is fine I guess..
@@GasparZoran-vz5no I have seen voltage fluctuations like that in few accords but I also seen stable 14v no change it’s very confusing with these new generation Hondas
Mines is doing the same on my 2015 Accord. I’ve just changed the alternator twice and the battery sensor and still getting 12.85 . Were you able to find the issue?
@@Chucky_1034 well this car was very worried it came back to me like 6 months later it was bouncing up and down 14v for few seconds then 12.50 for like 10 seconds and then went back up to 14 then down to 12 for few seconds then it stayed at 14 and it stayed there for like hour and I left it alone I believe 14 is the level 13 above should be good. It’s just worried
2015 Honda Accord base , Altenator is reading between 14.8 and 14.6. My battery keeps dying. I just got battery yesterday. Also got Altenator replaced last week. Is that voltage too high ?
Well the alternator dose provided 14 v only when it’s required not always mostly it will stay to 12v when under load with accessories on it will kick on 14
The voltage in my Honda goes 11-12 volts when I turn the A\C on. It is 14 volts when A\C is off. Is that normal?
I will check that and make video on that also
My Camaro goes to 12.** when I have blower motor on high speed and ac on but not 11
I guess it's kinda randomly asking but do anyone know a good place to stream newly released series online?
@Russell Keith Flixportal
@Ryan Knox Thank you, I signed up and it seems to work =) I appreciate it !
Sorry but do you know about Honda Dual mode charging systems? 12.5 to 12.9 is normal at idle. They only maintain at Idle Add a load then you will see your 14 .40
Yeah 12 Volts are on these new cars they only charge if needed to be for fuel efficiency
RB, I’m having problems with my 2013 Honda Accord exL same vehicle in this video.. keeps say check charging system with battery sensor and every other sensor on.. battery is 5 months old, alternator brand new.. car makes a clicking noise when I go to start and doesn’t turn on.. I put a brand new battery current sensor on the battery negative side.. I had a charging system charging the battery car starts then all lights come on, power steering makes the wheel hard and then rpm and gas go down to 0
So it’s stalling? Did u check alternator outputs
@@RBTheMechanic yea I changed battery current sensor, battery, and all my lights come on and still says check charging system
@@anthonyarodes366 Did you ever fix it? I have the same problem....
I changed my battery and alternator and still no charge. Can it be the alternator fuse? If so which is the fuse?
Did u out in original alternator ? It can be fuse check horn fuse and disconnect the battery sensor and reconnect or it
Thank you for explaining this was a huge help been having battery problems and everything but the parts store scanners that just hook up to the battery was saying battery and alternator were fine so was wondering how to check it myself with a voltage meter everything read fine but im still having charging issues just seems like my brand new battery is like drained and not getting charged fully also the alternator is brand new as well so im at a loss as to whats going on
Well change out the battery … also the check charging systym can come for any stupid reason I had some cars that had bad horn fuse. So check ur horn fuse and alll other fuses and scan the car for any codes
@RB The Mechanic ya the battery thats in the car now I had upgraded to the group 24 from the 51. I also bought the best battery I could. Battery reads 12.9 v with the car off and has been sitting over night so im kinda ruling out it being the battery. I'm getting my alternator warrantied at the parts store today. But last night when checking everything I noticed my serpentine belt is reallly really tight for some reason? It's weird to its not making any squeeling sounds or anything but the volts on the alternator at battery dropped to 13v last night right at midnight to no joke its like Way to start the new year off right huh? Haha anyways while i was inspecting it on thr side of the road last night i could barely move the belt in any direction and the joint that determines the tension seems like it extended as for towards the back of the car is it could, thinking it seized up maybe? It just rained really hard where I live and my fender liner is missing maybe that's what caused this? Also my car just hit 108k so I'm thinking the belt and the pulley needs to be replaced anyways. Gonna replace everything today and then go through my fuses as well. By any chance do u kno where the fuse is for the alternator? Been having trouble locating that
@@Lilnagger666 it’s somthing sensor related or voltages like I said fuses can be issue as well I had few with horn fuse blown
@RB The Mechanic for sure ya I just went through my fuse panel under the hood everything checked out I was missing a fuse for the parking lights tho idk if that would cause anything I mean it's been like that since I bought the car so idk I still put the fuse in tho. Only other thing is the arm on the pulley right at that bolt that hold the arm and pulley together right at the joint is super loose I can move this arm all around so hopefully the new pulley belt and alternator fixes all this. But check it out I noticed u and some other guys talking about your voltages dropping while idling. Ive never had my voltages drop under 14.4 at idle even with their being no headlights or accessories on so im wondering if my computer in my car was just working extra hard until last night. Although my acceleration was crap headlights went super dim so idk. if that is true your voltages are supposed to drop at idle could explain my low voltage reading although doesn't explain loss of performance and headlights being super dim. Hopefully all the new parts fix everything but hey man thank u for your help dude I really really appreciate u. All your videos on these cars have helped me tremendously so I appreciate it man for real.
@@Lilnagger666 u can change that sensor on battery as well it plays big role I had few that I disconnect and connect back and it worked
Car on the battery volt is 18volt what going on bad alternator?
Yeah too much voltage bad alternator prolly will fry electronics what car u got
@@RBTheMechanic 2018 accord
@@jygogaming3550 yup way tooo much voltage
My mechanic showed me the exact same readings you got 14.55 with the red on the alternator underneath that rubber cover thing and the black on the engine block and he told me that I need a new alternator and battery. 🤦🏻♂️🤷♂️. My car smells like rotten eggs so he said that’s coming from the battery?
Battery can smell like that I would replace the battery alternator seems good voltage
RB, I'm having trouble with my 2017 honda civic (starting to take a long time to crank). I was able to use this video to rule out the alternator as the problem. Thanks for sharing, it helps!
Start with checking battery and if battery is older than 3 years it got to go
@@RBTheMechanic I replaced the battery, checked voltages during startup and under load (2,000 rpm in neutral for about 2 minutes), never got above 14.6 V. But when left to idle, the voltage dropped to 13.1 V. Is the computer "downpowering" the alternator when not under load, or is this an alternator problem? When I do something simple such as turning on the headlights, the voltage would jump up to 14.4 V, as soon as I turned them off, it drops back to 13.1 V. Other than that it's acting normal and the battery was charged afterwards.
@@andrewgautreaux40 I do t think that’s problem when u out somthing in that puts load on engine so idle speed go up rpm goes up and alternator start to create more
@@RBTheMechanic Car's been running fine since the battery change - thank you so much!
@@andrewgautreaux40 nice!!!
I need that pice whats the name for that pice can you tell me please
Which pice
@@RBTheMechanic the pice from de battery
@@armandocamaja8411 the battery voltage regulator
everything in my car works fine all i need is the part you showed last
Have you ever done a parasitic draw test on these accords? I have a 2014 Accord that keeps dying after about 2 days of not driving. Replaced the battery twice now.
No I haven’t had a car with the type of issue but u have to connect the volt meter in line with battery and start pulling fuses to see if any makes difference start with radio fuse done lights trunk light
@@RBTheMechanic thank you. Will give it a try
@@RBTheMechanic can you make a video on where the starter relay/fuse is and how to remove it?
@@brindan1609 sure will down the road
Anybody check the E.L.D. Electronic load detector in the fuse/relay box
What the heck is that high frequency noise?
Normal noise camera just picks up every bit of noise
