---------------------------------------------------------------------------------------------------------------------------
A bad ground connection is one of the most overseen and neglected electrical car problems.
Although it's very simple to fix in most cases, some symptoms mimic more serious car problems (a weak car battery, bad starter, bad alternator, faulty electric or electronic components, or else).
This often leads to unneeded and sometimes very expensive repairs that solve nothing.
So before you go and spend a significant amount of money and time, take a look at this video tutorial. It may prevent this and perhaps help solve the bad ground connection problem yourself.

The jumper cable test worked for my 30 year old truck. I had no power inside the truck except the cab light. I was about to buy a new battery even though mine tested 12.6 volts. I turned the key on and hooked up one side of the jumper cables from the negative battery to the fender and everything came on inside. I cleaned the negative battery cable at the alternator. 5 minute fix after watching the video. Thank You so much!!!
Not to get too far into the weeds of esotericism, but grounding your barefeet to the earth can create stability and homeostasis in the body as well. My 2015 Charger was having no crank issues and just as you correctly stated, it could be a faulty ground game or “Bad Earth” connection issue..Everyone should buy a multimeter and self jump battery capacity for a good educational DIY experience. Remember cars and computers are mimicking our internal human electrical system. Thanks for this..
Out of all the videos here on TH-cam about checking the ground connections, I actually understood what to do. Thank you for making it easy to understand. Have a blessed day.
You're welcome and thanks for watching!
@@DespairRepair So how do I test the 2007 Audi Q7 with battery being not under the hood. It's under driver seat inside vehicle. How am I to test ground using your method explain here with the multimeter?
@@Heylo7 hi and thanks for watching! Do you have remote battery connections under the hood?
Also, what do you want to test? Is the engine grounded, the body, or else?
@@DespairRepair yes I have positive connection and the ground connection posts to under hood driver side of the engine bay. I want to test for ground. Using your method from what I watched in your video here. My multimeter is a cen-tech cm300 and the dials numbering on it start at 60 600 6000 etc it's not the one which let's you set multimeter to say 20 200 2000 etc mines not like that.
@@Heylo7 what's the problem and why are you testing?
Finally someone that breaks it down in a simple form, I've been having some issues with my Jetta. Pretty sure it's a bad ground connection or ECM. This video helped me understand how everything goes together and how to use a multimeter as well.
Hi Dwayne, thanks for watching and for the nice comment.
Glad if the video helped, we try our best to simplify.
By the way, admire the skateboard skills :-)

Did you replace the ground?
Lemme guess. Mk4 vw
Updates lol?
very helpful video! thanks. had alternator low voltage charging and also heavy cranking! In the process of trying to find the bad ground but the video certainly points me in the right direction. thanks!
I think my car might have a bad ground connection, I will definitely follow these steps. I am very impressed by the way you explained everything, you made it so simple to understand and easy to follow. Thank you very much.
You're welcome, thanks for watching and for the kind words 🙂
Thank you! I actually understood what to do! Very informative and kept it simple! Thanks again!
Hi Jessica! You're welcome, glad the video helped, and thanks for the nice comment! :-)
This guy could be a Stunt Double for Kris Kelly on Bering Sea Gold.
Good video!
The jumper cable method is pretty fast. Idk about newer cars but I've also heard of people creating an additional ground on older vehicles. I suppose for a ground diagnoses in conjunction with a certain ground not easily accessible or the area of ground conection is simply too oxidized. May as well check out the condition of the positive cable while you're poking around.
My truck has a slow start, takes an extra crank, bit of a lope. Charging system/battery is good, might just replace the battery cables for the heck of it, see what happens. Its 220,000 miles and a decent amount of corrosion akl along the inside of the cable. So even it doesnt solve my problem, I feel compelled to do it.
Come check me out.
Thanks for the informative video.
After a flood, my 2016 Chevrolet Impala LTZ limited had all kinds of problems.
I cleaned the gearbox, the radiator and all mechanical parts. I replaced BCM module, climate control module, instrument cluster dash panel and headlight dimmer switch.
Car has a weak start and Reverse lights ONLY work with brake lights.
I'll use your video to troubleshoot.
You give a lot of common-sense remedies to car problems, I like the way you present solutions!
Thank you for the kind words and for watching! 🙂
Thank u very much. Highly informative.simple to complex approach.
Replaced FIVE starters (each one lasts maybe a month!) so thanks for this very helpful video, looking for all the ground connections to see if heavy cranking is burning them up due to poor ground. Maranatha
Hi, thanks for watching, and glad if the video helped!
Hope you solve the problem, a bad ground connection will fry the starter for sure.
Check if you have a ground strap from the engine or transmission to the chassis or body.
I had the same problem and consulted many mechanics. Some said the problem maybe the battery and others starter. I had it fixed and it's okay.
Definitely One of the better videos I’ve seen regarding this bad ground issue. Thank you 🙏
You're welcome and thank you for watching!
Lesson learned. Wished I'd seen it sooner before the new battery. Thanks so much.
Very informative and well-explained. Thanks for posting!
You're welcome and thank you for watching!
awesome video! imo, everyone that drives a vehicle should know this info. keep up the good work!
Thanks for the nice comment and for watching!
Thank you sooo much!
I don't think I have this problem but the information is sooo useful.
It will save hours of looking for an electrical fault...
I have similar symptoms to those below, and I think it maybe the alternator, but this information will help eliminate a lot of possibilities!
... And so easy to understand..
I am definitely subscribing 👌
You're welcome, thanks for watching and hope the video helps solve the problem.
At 12.06 VDC, that lead acid battery is down to approx 35% and should never get anywhere near that considering as soon as you start your car, the power used to start is replaced while driving. I would load test the battery with a load testing diagnostic tool and see if the battery is shot.
Very informative,thanks and God bless!
Thank you for the informative film. Today my husband and me drove to another city like 40-50 miles. After a short stop (~ 20 min) I couldn't start the car: lights came, no crank, then everything goes off. I tried 3-4 times, then husband vent to see what is going on under the hood when I was trying to crank the car. He saws some smoke coming from the positive terminal connection to the battery. The smoke appeared on attempt to crank (it lasted a ~ 1 sec, a little bit of smoke). I wanted to see it as well, so husband was cranking, I saw that smoke, brushed the terminals w/metal wire, but still no crank. We were about to call AAA, but then he tried again and the car started like nothing happened before. We came back home (another ~50 mi). I checked the battery like 1 month ago at NTB place, it was good. The battery is almost 5 years old. On another battery (it went bad on another car), I've head an opinion at Autozone that a battery is not good in 5 years, so I went to see what deals they have at NTB. But at NTB they insured me that there is no need to buy a new battery or have a spare one with the battery I have. May I know your opinion what could cause that smoke. It is obviously overheating, but what causes it?
Hi and thanks for watching!
I would again check if the battery clamps are clean (the inner side that connects to the terminals) and that the clamps are properly tightened.
Smoke and even sparks can appear if this is the problem.
Hope this helps.
You helped me, I knew I had a good battery & the alternator was fine. I was told my battery cable was recalled. I'm stuck 400 miles from home, alone & need to get back. I cleaned the one accessable ground connection & haven't had trouble since. Thank you very much for the info. Now my serpentine belt is squealing & I must replace before my trip. I've had one blow before & it busted the water resivour & temp guage.
Glad the video helped and thanks for watching!
This video solved my no crank no start totally dead car. The voltage measured on the battery terminal was 12.5 volts, however, when the negative probe was moved a few inches away from the battery negative terminal, the voltage went down to 10 volts. The problem was a rusted and corroded connector on the negative terminal. Thank you for this video. Appreciate it.
You're welcome very glad that the video helped and thanks for watching! 🙂
I have this problem, did you replace the connector?
@@mouszzy9256 no. I just cleaned it.
Great information. Always learning👍🏼

MR. Despair Repair, thank you for helping me to understand bad ground connections on cars. I am currently restoring a 1986 Toyota Camry Le in Baltimore, Maryland.
You're welcome and glad if the video helped! By the way, very good car, and good luck with the restoration.
Very clear presentation! Thank you.
Very good information . There was a couple times where I couldn’t see what area you were referring to because you were in the way . Do I. Heck a Cadillac 2913 xts premium the same way?
Tks for sharing. Nice tip for checking ground on body then engine 👌
Excellent video and easy to follow!! Thanks for sharing 😊

Thanks. Your video really helps! Easy to understand and well explained. 👍 up from Malaysia 🇲🇾
You're welcome and thanks for the nice comment!😀
Thanks for sharing this video about checking your grounds, it give me a better understanding of what to do.
Also you should also show how to do a resistance ground test with your multi meter, as if your multimeter shows High Resistance values that means you have a ground break somewhere that's another way of doing it.
Hi Steve, thanks for watching and for sharing!
You're right that's one more way of showing a bad ground connection.
Thank you, I have a problem and you solved it right there. Cheers bro..👍
You're welcome and glad the video helped :-). Thanks for watching.
Hi thanks greta video. had nothing but problems with Skoda Fabia Monte Carlo 1.2 TSI . Change Alternator and fitted new battery and still the same. However after watching your video. i checked the ground connections with a multimeter. When the car is running it should around 14.2 volts, im only getting 12.6 on the battery and the ground connection on the bodywork. But when I put the negative lead on the engine metal I get 14.6V. What does this mean? I also cleaned the ground lead.
The best video for ground problems Iv seen. Thank you

Thank you once more and thanks for watching!
I didn’t know about the jumper cable trick, I need to try that! I did a head gasket job and had a long period of time where I wasn’t working on it so I can’t figure out so far where two of the (supposedly ground) terminals go. I bought a new battery so if it works after I do that trick then I’ll be able to run it while I’m waiting to find where those wires are supposed to go. Even my OEM shop manual didn’t list those points, maybe they’re in a different area of the manual. Maybe I’ll be able to find a junkyard car I can reference.
I was having other issues like my dashboard flickering, being dim, or even spazzing like the needles and the lights, those were likely the ground wires I had touching the engine being sporadic.
Hi Wyatt and thanks for watching!
Yeah, it's a good first-aid measure, helped me a lot a couple of times.
Most manuals (even the professional ones) don't have these points stated, why I don't know, as they are very important.
I would first look at the connection from the battery to the car body and from the body to the transmission or engine.
Some cars don't have a ground connection from the body to the engine/transmission, it rather relies on, for instance, the connection made by screws on the engine mounts (which can also cause ground connection problems).
Best of luck with the repair!
What is your take on the big 3/big 4 electrical ground/charge upgrade?
Great video, very clear and helpful in not only spitting a problem but how to fix it too.
Thanks for the kind comment and for watching! 🙂
Hey thanks for making this vid , my sisters 04 matrix has a dim battery light. I believe it's either a bad ground or the signaling wire is corroded. Thanks for teaching everyone how to test ground quickly!
I subscribed and liked haha.
What did the issue end up being? Im having a dim light too
Thank you. It really was bad grounding wire from body to motor. That voltage meter test solved it. It caused a ton of problem, destroyed charger, fuses, etc. Good channel.

Geez mate. Where were you yesterday and the night before? Luckily we did end up diagnosing a bad earth. Another symptom of bad earth is the earth lead gets hot when cranking. Thanks for you upload champ.
Hi, thank you for watching, and nice to meet you!
Yes, that's another common symptom, and thanks for sharing the information.

Ok,great content and very clear.
I recently installed a new rádio on my car and it's been a bumpy ride since.the radio will shut off and turn back on if i use the ac or sometimes if simple the fan turn on.i was parked yesterday and the whole car shut off,pls let me know what you guys think it is
Thank you
Hi Tom and thanks for watching!
I would check (if you already haven't) the battery terminals for a good connection.
Also, try checking the power supply to the radio (+) wire.
I have a fuseable link on my pos battery connection & it keeps blowing. This is prolly my issue too huh? Cuz my windows wig out & my key fob don’t work or alarm. Gratitudes my new friend :)
Hello! Great video. I have a question. If my car battery is in the trunk, would I use an incredibly long extension wire to ground/test the engine block and chassis? Or would I put my positive test lead to the engine fuse box? Thank you
Use two short cables. One between battery negative to clean .body point in trunk the second between engine bay body to engine.
Guru here, be mindful when redesigning (adding wires) to any vehicle. Often voltage drop and or path is used to do interesting things. Like when cranking an 80s ford a brake light bulb test is accomplished on dash bulb (the front rear proportion valve indicator) to many charging systems measuring voltage drop accros a certain length of wire in the ground path to regulate charging current. Bigger is not always better when rewiring one of these type of systems.
كل الشكر والاحترام على مجهودك والمعلومات الجيدة
Thanks, that was a great one, you can also add to check ground to ground with the ohm meter function, that can help as well to chase bad/glitchy ground to ground connection, also how to clean those ground spots to make it fully complete, otherwise I really like this really great tutorial, kuddos
Thanks for watching, for the suggestions, and for the kind words! 🙂
Yo you saved me some damn money fr fr bless you dawg 🙏🏼💪🏼👍🏼
thanks. simple and spot on unlike the other videos who talked and talked like my wife without any substance.
Really thanks alot for the very useful video. Question: When doing the bypass jumping cable , should I turn ingention key on or leave it off ? thanks.
You're welcome and thanks for watching!
It would be better to first turn off the ignition and then connect the cable.
Am not electrically incline so am very much grateful for this.
Hi, you're welcome, and thanks for watching!
nice video.
you could have made some diagnosis eg. when the charger wont charge the battery, the ground to the engine is faulty etc.
also after cleaning and before refitting - grease the connection with copper paste, to prevent the malfunctioning in the future.
Hi, and thanks for watching!
We've made a video about how to check the alternator charge. You're right about the copper grease.
Thanks for sharing.

Hi, thanks for watching and for the kind words :-)
Sir , when i on my headlight the engine rpm increases slightly in idle position.The dash board lights gets slightly fade too. I feel now a days that my headlights are not enough bright too. What could be the problem?
Simplified video. Thank you. My battery light stays on the dashboard for like 2 to 5 minutes after starting the car before going off. Any leads? Battery Voltage is 12.8V.
Also I want to believe that there is a separate ground connection between the battery and the gearbox as well.
Thanks for a very simple to understand explanation. I now know what may be the cause of unexplainable issues with my daughter’s Yaris. She’s already replaced the alternator so hopefully we can find what’s causing the car to be absolutely dead one day and starting the next, it’s totally weird.

I’ve had a bad computer do this
Great video! Thanks!

This video and the comments are helpful. I have a 2007 Chrysler Pacifica the wipers, horn, radio, don’t respond. The voltage, airbag, ABS, parking brake and traction indicators are lit.
I’m hoping this is an issue with the wires and them needing to be reground
Hi Jamar and thanks for watching!
Could be, give it a try. Besides the ground connection, I would check for loose or rusty connections.
Was that the issue ? And did you fix it?
Good ,clear presentation.👍
Thank for the kind words and for watching!
Thank you for a good lesson sir.
You're welcome and thanks for watching!
I have for decades: put a ground wire from battery to the engine and an extra ground wire from the battery to another spot to the body! And the most cold cranking lamps battery in it! And not an cheapest battery/ a good battery which co$t more $money but worth it in WINTER and BEYOND!
I have a low mi. Lincoln town car ,2005 with a no start in park but in neutral always, once in about 50 normal starts. I've done neutral switch, starter and battery. This has been tough to figure out! HELP!
Great video.
I have an issue with my Octavia which says fuel regulator short to ground on the odb reader.
I will check the ground connections this week. Hopefully it is this and an easy fix
Hi, and thanks for watching! Good luck with the repair and thank you for the kind words🙂
My ground strap bolt on the engine broke from the head on the engine block and off course I don't have the tools 2 get the rest of the bolt out.
How will it affect my Jeep Compass? I was able to kind of secure 1/2 of the strap end 2 another bolt on the engine, but it is not as it should be!
Thanks for your time!
Hi and thank you for watching!
I think you should be fine provided that the engine starts well (there's no heavy cranking).
Half of the strap should be enough for the installation to function properly. I've had these kinds of cases where I needed to improvise, looks bad but functions well.
But if you want to be 100% sure, buy a new strap, make a brand-new connection, and call it a day.
Hope any of this helps
Damn good video to the point!
For the jumper cable method… the red cable goes on a solid body metal right? And is that with the engine
Hi thanks good video. If I found a bad ground but can’t get to it to change it ,can I just leave it and bypass to another area on the car. I have flickering lights.
Hi and thanks for watching!
Yes you can, as long as your sure it has a good connection and won't interfere with other systems and appliances on the car.
Great tutorial! The climate control lighting in my 2009 volvo only lights up after it rains and only for a short period of time. Would checking the ground be a good place to start with this issue. Thank you!
Hi and thanks for watching! Well, it can't hurt to check it out.
Than you for this wonderfool video
,I think now I can find the ground fault in my car.
You're welcome and thanks for watching!
When cranking I usually get a click, and I have to try to crank it a few times, after 2-4 times it works. I drive a 2002 ford focus se if that helps.
Hi Brennen and thanks for watching!
That kind of fault can be caused by a number of things.
The first that come to mind are a bad starter solenoid, worn-out starter brushes, worn-out ignition switch, loose or corroded contacts to the starter solenoid, and so on.
If the starter is OK, try checking the battery terminals (if there tightened and cleaned) and the main ground connections.
Hope this helps!
Nice video. More informative thank you. I just subscribed
Thank you very much for the kind words and thank you very much for the sub 🙂

good information. Can you tell me where I install the ground to my Ram Promaster 3500 year 2014? please thank you
at the negative battery and any screw on your car body.
Amazing video!!! Thank you! Just one question, is an ABS problem could be a consequence of a bad ground connection? I'm struggling finding why my ABS has problems without having any faulty code from the diag
Cheers
Yes, a bad ground could cause the ABS module not to communicate
Autozone can read the code for free.
@@waltersweet4595 cheers mate
Great video makes sense, where can i find all the ground locations? I have a 2002 GMC Sierra 1500
Is there a publication stating this info?
Thx Again
Hi Cliff, thanks for watching and sorry for the late reply!
The best place to look is the repair manual. In them, you have the exact places where the ground connections are.
The usual connections (for almost all cars) are from the battery to the car body and from the body to the engine or transmission.
Hope this helps.
@@DespairRepair thx will look for a manual
That is good for understanding ground issue in my car. Thanks 👍
You're welcome and thank you for the kind words 🙂

Hi, thanks for watching and for the kind words!
Awesome video. I just was curious if bad grounds can cause the ecm code P0603 to come up because a few months ago a mobile mechanic forgot to put the washers back on the alternator when replacing an old exhaust manifold. So I had to get a new battery fuse for the positive side cable. Ever since then the code P0603 has been coming up and I’m trying to figure out what cable or whatever might have went bad so I can get it fixed?
Hi, thanks for watching and for the kind comment!
Regarding the washers, they need to be there but if the contact is good, it missing should not cause a problem.
Yes, a bad ground connection can cause this kind of error code and this is certainly worth checking.
But I would first check all of the basic connections like the battery clamps, alternator connections, the mentioned fuse and every other place that has to do or is near the repair that was made.
in lots of cases, like that, a bad or missing connection may cause a problem.
Hope this helps at least a bit.
Best of luck with the repair.
@@DespairRepairyea I forgot to say that my vehicle from time to time jerks/stalls and that’s what I’m trying to fix along with the code P0603 going away.
@@cameronmorgan0203 well that could literally mean dozens of things.
But if the ECM doesn't function properly then that's what will happen since the computer probably can't regulate the air/fuel mixture, ignition system, and else.
This doesn't help anything, but again: I would check the repair that was recently made.
Not saying it was a bad repair but if everything worked good before that, it is the main suspect.
I would check if everything is tightened, well connected, properly returned into place, and so on.
Very helpful video… I found that my negative battery connector was corroded & had a small crack, so I cleaned it with contact cleaner & a wire brush!
Hi, and thanks for watching! That's the right thing to do.
Thank you. Well presented. Perhaps in addition provide how to properly and specially clean the connections. What substance to use?
Thanks for watching! There are various methods, once you get the acid corrosion off the terminals (if there is any) you can use sandpaper, a file or even better a battery terminal cleaner.
Very informative and clear 👍
Thank you for watching!
Hi and thanks for the information...I have a Vw polo 9n which is basically almost the same car as the skoda you are dealing with...Ive had some problems with the immobilizer and in a car shop they told me its a faulty insturment cluster and i changed it and now the problem with immobilizer is gone but the intrument cluster started acting strange 1 month ago when it reset itslef while driving and now one morning when i went to start the car i noticed that there were no digits in the intrument cluster and when i turned the key the car started and then it died...What might be the problem ? thanks
Hi Niko, thanks for watching and sorry for the late response!
I would first check the alternator voltage and if the battery clamps are clean and properly tightened.
What you can also do is try asking the people who replaced the instrument cluster. Maybe there's a weak connection somewhere or lose connector.
Hope this helps at least a little bit.
Last winter I had a no start due to corrosion inside the battery terminal cable. I'm back to having no start and thanks to this I know it's not that but still don't know why it's not starting.
Hi, thanks for watching and glad if the video helped
