Bad Ground Connection On Cars-Meaning,Symptoms, Diagnosing and Solving The Problem

[@joe2thesequel]

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!!!

[@abdelmalekbeo7576]

I clipped every connector under the hood, even the ones to the battery. I replaced the Battery connectors with Brass ones, replaced a few ground cables (easier) from the body to the engine. Plugged the battery cables back, turned the ignition and all lights came on, the car started better than it used. Thank you so much. The Electricians told me I needed an ECM (Computer) and a new set of keys. Your video saved me $700. Thank you thank you thank you.

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..

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.

[@olenaerhardt7725]

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?

[@DespairRepair]

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.

[@jeffreystroman2811]

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.

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.

[@DespairRepair]

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!

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!

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?

[@DespairRepair]

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.

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.

[@MrRander7769]

Sometimes it is about Amperage more than it is about a electrical connection. The starter uses 300 Amps headlights maybe 20 amps, so the body ground doesn't have to have a big cable to run the lights. In your car the starter is dependent on the body to ground strap to to work. I like to run a ground strap from the - negative battery post to the engine block where the starter motor is connected. Sometime there is only a small 20 amp grounding strap from body to engine. That shows as a good ground but not a large cable that the starter is needing. So it shows 12 volts on the meter. 0 ohms between negative post and body. But high resistance for the starter

[@DespairRepair]

Hello and thank you very much for sharing! The best ground connection is like the one you've described. Not very nice to see (in some cases)but a very effective and longlasting solution.

@@DespairRepair I checked today with the multimeter everything was fine the batterry an the alternator.. But when I checked the radio wiring sometimes it shows around 6 volts thats when radio wont turn on but when it does Its at normal value 12volts.. What could be the problem?

[@DespairRepair]

@@roberthengeric1953 to be honest there could be a couple of things. Even at 6 volts, it should show something. Did, you try to connect the multimeter between the ground and the plus connection, what's the voltage? Also, did you try to connect between the plus and ground somewhere else on the car? Is there another connector somewhere deeper in the installation?

[@roberthengeric1953]

@@DespairRepair Only the button lights light up on the unit but they flicker.. tried to connect the multimeter to the ground but Its still 6v, i will try to hook it up on different ground. Thank for the help!❤️

@@roberthengeric1953 you're welcome and sorry I couldn't help more. I wish you all the best with the repair.

Hello I got a 1999 Dodge ram 2500 I got a code po462 low voltage on the sending unit how can I fix the gas gauge gas light is always on I changed the cluster and fuel pump and sending unit????

[@toms6756]

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!

[@DespairRepair]

Hi and thanks for watching! Well, it can't hurt to check it out.

[@cirohernandez4073]

good information. Can you tell me where I install the ground to my Ram Promaster 3500 year 2014? please thank you

[@marspluto3382]

at the negative battery and any screw on your car body.

[@Cgtlfa]

For the jumper cable method… the red cable goes on a solid body metal right? And is that with the engine

[@hollywoodactress]

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

[@DespairRepair]

Hi, and thanks for watching! Good luck with the repair and thank you for the kind words🙂

[@prasanthradhathiyagarajan8196]

Does bad ground connection to body to engine cause battery power drain ?

[@DespairRepair]

Hi and thanks for watching! Not that I know of.

[@josephherron7671]

No. But it WILL cause a low voltage reading until it’s fixed.

[@XMALL]

EXCELLENT! Attention to details that mechanics all around don't do. You should consider teaching it. You are quite good my frind! thanks for all your videos !! I have checked your website.. AMAZING!!!!!!!!!!!!!!!!! AMAZING !!!!!!!!!!!!!!!!!! Be safe!!

[@DespairRepair]

Hi, thanks for watching and for the kind words!

[@jepchang]

Thanks it so useful to me. My yahama r6 have some firing problems, before i replace stator or ignition coil i better check the ground connection. Coz some days my bike running some day it running bad

[@richard.b6054]

Thanks for the video very beneficial. My Corsa d o/s indicators working intermittently specially when is hot so thinking bad ground points. Is there always one that is responsible for the indicators I can check directly or could it be any of them?

[@DespairRepair]

Hi, thanks for watching, and glad if the video helped! It could be any of them, but if it's one of the main points then usually numerous problems appear at the same time.

[@entertainmentforyou6677]

I have a 2005 ford escape xlt and driving home tonight all the interior lights, high beams. Blinkers shut off but the car kept driving! When I shut the car off and turn the key the interior lights and Blinkers everything works but when the engine starts all the electrical stuff shut off! U have an idea you can help me with? Thanks

[@DespairRepair]

Hi and thanks for watching! It could be a couple of things but I would first check the battery clamps that they are tightened and clean. Also, I would check the cables coming to the clamps. After that, I would consider checking the ignition switch.

[@aplusroofingllc9773]

Hi i have a rough start when starting my car, and once it turns on and warms up when i go to turn it off and doesn’t want to start up anymore until it cools down a little there is some corrosion on the ground that’s connect to the engine block . Did the multimeter test on some areas it reads good on others it reads really low like 8. Something. Could this be the issue ?

[@DespairRepair]

Hi and thanks for watching! Could be and I would clean the ground connection just in case. It could also be the starter. But before spending money on repairs, try connecting a jump cable from the minus battery terminal to a safe metal spot on the engine block. Then try to start the engine. If there are no problems, then the ground connection is the issue for sure. Hope this helps!

[@edwinramirez1459]

I have this exact problem what was the solution in ur case?

[@lewispickles6402]

Just adding on to the heavy cranking - In some cases, your car may not crank at all! My VW Tiguan has a snapped earth cable from the body to the gearbox and this caused it to not crank at all - Replacement cable coming this weekend and I will attempt to fix this. Do I need to disconnect the Negative terminal when doing this?

[@DespairRepair]

Hi Lewis and thanks for watching and sharing your experience. It would be best to take off the negative battery clamp just in case. It's safer that way, both for you and the car.

[@lewispickles6402]

​@Despair Repair Thank you for getting back to me - Keep up the great videos, I have subbed 😊

[@johnyoung2614]

I like your video but the filming and editing needs to improve... remember, Show Not Tell, ie. Show us how to locate the ground connection, and show close ups of bad ground connections. Then you'll really have a great video. Just commenting, Thanks.

[@DespairRepair]

Hi John, thanks for watching and for the sincere and useful comment! You're right, hopefully, in the near future, we'll improve the quality and lighting which is sometimes really off, to be sincere. Regarding the examples, we try to combine explaining and the repair as much as possible. The main point is to get the point and idea of the repair to our viewers. Anyway, we hope the video helped 🙂

[@tammyshreve3768]

Can you use the same ground connection on the firewall to the engine and from the battery to the engine two wires ran one from the battery to the engine and one from the body to the engine can you use the same one on the engine or do you have to have two different placements for the ground cables I hope that that makes sense it's pretty much I have the battery from the negative run into the engine and the one from the firewall running to the engine

[@DespairRepair]

Hi and thanks for watching! In my opinion, yes you can, provided that the connection is done properly and that the cable is thick enough. Also, there should be enough place to tighten everything. All in all, if it works, I'd leave it alone. Hope this helps

[@seriously1784]

Thanks for the video, it is very easy to understand and follow.

[@DespairRepair]

You're welcome, thanks for the kind words and for watching!

[@StacksFamilyTransport]

I have the heavy cranking “womp womp womp.” I replaced the battery and alternator. But my connections looks a little exposed. When I was cranking it my negative ground started smoking and turning red which indicated I have a problem there. I’m not sure if my alternator have a connection problem either.

[@DespairRepair]

Hi and thanks for watching! If the engine isn't properly grounded then more or less anything won't work properly including the alternator. Maybe best try connecting a jumper cable from the minus terminal of the battery to a convenient metal part of the engine and see if the connection is the problem. There is a part of the video showing that I think. Hope this helps.

[@DGSantaFe]

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!

[@DespairRepair]

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

[@alexurrutia5982]

thanks for your video, I'm having a slow cranking engine just when the car is at normal temperature any idea.

[@DespairRepair]

Hi and thanks for watching! It could be lots of things, starter and engine related.

[@MrSamiAlamir]

I had a temperature problem. The indicator always goes higher at night but everything in the engine seems fine it took me a month, this problem goes away when I use a jumper cable 😅. I kept it installed since

[@jamarshallah]

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

[@DespairRepair]

Hi Jamar and thanks for watching! Could be, give it a try. Besides the ground connection, I would check for loose or rusty connections.

[@dawnjackson4640]

Was that the issue ? And did you fix it?

[@rickironblast]

My Mazda 3 hatch from 2006 has this issue with rear LED(OEM) tail/stop light. Only left one turns off after pressing the brake pedal. The indicator works fine. Bought a new assembly, same issue, plugged it to the right side, same - not working. I've plugged the right assembly to the left connectors and it works fine! So the left just sometimes turns on, like in the morning or randomly....stays on but then when I press the brake pedal, turns off again. I even replaced the passenger junction box - same issue. Replaced the brake switch. Battery is new. Alternator seems fine. OBD doesn't show any fault codes. The only thing I haven't looked at is grounding, and maybe something else, I don't know anymore...

[@DespairRepair]

Hi, and thanks for watching! Take a look at the grounding but also at the connector that goes on the lamp. Check the pins to see if they are tight and that there's no corrosion or filth. This is a common cause of problems.

[@coyoteloverosesalas3470]

I changed the starter it all started when my radiator blow and after that my car won't start then I changed the faucet on positive terminal and it burned the fauce now I don't know what else

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.

[@DespairRepair]

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.
