In my understanding that's a wrong test for checking the ground for any circuit beacuse the circuit u checking is not loaded yet and it's a possibility the ohm meter mislead you with wrong back emf readings, the best way to check gnd ckt is use your test light with one probe at negative and after loading the ckt check the ground block or terminal if it's glow it is a bad ground🇵🇰🇵🇰
This is a very good informative video, but there is one issue it did not cover. He touched the clean metal end of the ground wire, which only shows the wire is good but does not check the connection between the wire and the motor itself. So another step should be to do the same test to a point next to where cable is bolted down to. This will show that the connection and cable are good.
You should check out “Eric the car guy” He’s probably got a video on how to do a fuel filter. I must tell you if you’re going to do a job like this, definitely make sure you disconnect the negative battery terminal from that point on it’s simple, use a flathead screwdriver or a socket and remove and replace . Make sure the arrow is facing the same direction that it was before you removed it. That’s very important!
Great video really helpful . Tho was wondering how I would teat a bad earth on a earth somewhere at the back of the van or elsewhere, I have lost my wash wipe motor and clock, outside temp and now my horn hemal stopped working as well. All this happend after changing tiny bulb for the heater controls and it blew right away. Then everything else stopped working. Do u think this is a ground fault. Or short circuit , it driving me crazy coming up for my next mot next month..

Awesome video! Got a question, I'm recently having some voltage fluctuations while turning hazards lights on, it varies from 0.2 to 0.4 volts, it's also perceptible as an small vibration on my car, do you think that issue could be related as a faulty ground connection also?

Hi, thank you for your video. Do you happen to know or have a video on the location of all the grounding points of the Dodge grand caravan? Thanks again.
Interesting, but rather than measure Volts it's best to measure resistance. Wether it's Volts or Ohms the circuit needs to be under some sort of load. A test lamp (with a bulb) places a load on the circuit. LED ones don't. Proper electrician's Ohmmters stress the circuit with about 300mA at 12V so provide a reliable indication of a poor connection. On a car, continuity readings should be
Using resistance is a static measurement u need a dynamic measurement which is LOADED circuit ( vehicle running) Use your volt meter and check for voltage drops the ground side should be
Hello, what if you do what you did on the grounding points, and it has all 0's, when your battery is good? Just trying to make sure I am understanding this right.

Great vid..so once you have established a faulty ground is the next procedure to track the said wire back and locate where the issue is?...specifically i have a renault master 2013...think i have narrowed it dwn to an electical issue...posdinly a ground from one of relays in bonnet fuse.... identifying where though is my next issue..going to look for other vids of yrs and see if i can find. If u got any tips they b appreciate d Cheers ag as in
Hi,is pcm controling voltage on negative wires too?I have a problem with fuel pressure regulator,i measured the voltage at it s harness and shows 0.25 v,with ignition on,if i take ground from somwhere else shows the battery voltage,12/14 depends on how full it is,also i have the p0090 code,the question is,if i take the ground from somewhere else not from the wire that comes from pcm,would damage something,pcm or f. p. regulator?
YW, your lesson was clear and precise. How do I check whether my car battery is draining when engine is off. With engine off if I take the voltage reading between the +ve and +ve terminals and also between the positive and the grounding terminat, say at 12.14 and after an hour if I check the voltage again connecting the multimeter as before and if the voltage is less than 12.14 does that indicate that the battery is being grounded through some application such as the central locking or the theft alarm or the stereo [ i mean the gadgets that are suposed to be working even when the engine is off' Can you plese guide in this matter with Regards and thnking you for an excellent video
Could you use the multimeter on diode setting and touch the negative terminal and whatever spot you're testing? You should get a beep or near a dead short reading for a good circuit. Is there anything wrong with this strategy?
When I do this test on my old Buick, the display on the meter shows only zeros. If I use the POS terminal to do the probing then I get a valid reading.
Hi, I have a toyota corolla 2017 manual transmission. It draws 140mA with the alarm activated all doors and lights closed. It is the dome fuse that draws 60mA out of the 140mA. It then turns to 10mA when a relay clicks after 20 mins. Is this normal? I hope I get noticed..
Hi there came back home all is well in the car park in the drive way when i start the car nothing no crank but battery strong i just replace the motor starter last year the ground strap in the engine looks new the only bad ground strap i see is in the tale pipe exhaust its all gone you think that will enough to contribute not to start the car?
I tried your method of finding a ground fault. The display on the Klein multimeter showed zeros when I used the negative probe to touch the car engine or body. When I used the positive probe I got valid readings. What's up?
i would consider this a test for an open ground, open circuit... a ground fault would be a short to ground. if were switching across the ground or the positive results would change.
@@SicarioDistrepoyou're comment was not requested, ever. Ever think of that before leaving an unnecessarily jerk-off comment which added absolutely nothing to either confirm or deny the original comment? You see, the purpose of THIS comment, (which is also not requested by anyone) is to expose your ignorance. Apologies for the rudeness.
Issue with your methodology; A ground fault can PREVENT a vehicle from running. Which is possibly why you typically measure in ohms to find a ground fault, rather than voltage
A ground fault does not just have to prevent a vehicle from running... It could be anything from a bulbs shorting out to ground to a bad engine to chassis ground causing a misfire or worse (fire after a throttle cable is used as ground if engine ground is left disconnected).. I agree ohms should used to measure resistance between two points of contact to find a bad connection or wire. Volts is normally used to check if the charging system (alternator) is working properly, but this video is a good idea to check for "parasitic drain" caused by devices drawing power while the engine is off
@@OidHunter I didnt say has to, I said it CAN prevent it. Not that it always will, but uts always a possibility when dealing with grounds. Depends what grounding point has issues
Hello . I’m trying to do this test . When i touch negative and positive battery terminals , it shows 12.6 . And then i do the same with battery positive terminal to xar ground point but the screw and all around it , very rusty . It’s like crumbling metal . I can hardly see the screw . When i touch the screw or surroundings it gives me no reading . Unless i touch the touch the end of the cable . Would bad , rusty screw affect the ground ? Sorry i don’t mnow much about this

My friend's truck will not start and they are telling him it is a wiring issue, they have had it for over a week and haven't found the faulty wire yet. What should he do? He says it turns over but does not start, I say check your starter, but he insists he has a good starter. I said the same thing until my stopped, it gave me no warning, it just went to one click, and so I took out the battery first and had it checked, found a bad cell so I bought that, then it still would not start just the same thing, one click, so I got the starter off took and got another one, it started. How can he be so sure his starter is good? It is trying to start but it won't engage. How can he know it isn't the starter?
My multimeter won't reach all my grounds, having trunk mounted battery. I understand I will need to use wire or cable to complete the connection as needed. My question is, would I see a difference in voltage having to complete the circuit with let's say an appropriate quage wire, vs solely multimeter? Or could I use the power wire closer to ground I'm checking? Hope that makes sense and my wording was direct enough to understand. Thanks in advance 👍
Disregard as after commenting, I scrolled down and saw my question had already been answered. Well the main question anyway. If you have any info on others I asked, would be much appreciated 👍
Hey there! The thickness of the wire you use is not really that important because it is not under any load to simply take a reading with a multimeter. So pretty much any wire will do for extending into hard to reach areas if just doing these kinds of basic ground fault searches. The voltage should stay the same, or near as dammit as again it's not under any real load. Yes, you can use a power wire closer to where you are working if you have to, HOWEVER if you get strange results you will likely also want to re-test with it direct to the battery before you consider it a definite fault as you don't know what circuitry is between the battery and that live wire that could affect the readings. Direct to the battery is definitely the best way to go for ground fault testing!!
@@YouWrench My 95 Ford ranger keeps blowing starter fuses. Do you have any ideas as for what maybe causing this? I check ground to the battery and also the starter wires..Please,Please respond. Thanks
My resting voltage is at 11.9 on a new battery, new alternator and new wiring. When I go down hill and take my foot off the gas my voltage goes to 14.5 but when I put my foot on the gas and accelerate the voltage drops down to 11.9. Then every now and then when I drive my voltage stays at 14.3.. but most of the time its at 11.9.. Any idea on what could be the issue?
Hey there! No, that would be very unlikely. Everything that needs to be weather sealed typically is (or at least starts out that way). You have to remember how much water from rain and spray the bottom of the car is subject to. It is possible that paint could have got in somewhere it shouldn't (like a connector for example). But simply painting a screw or bolt head should not typically cause a ground fault. Hope that helps 👍
Yes, it is a possibility. However, the xenon ballasts can and do go faulty, it's far from uncommon. You could test the earth going into the plug of the xenon ballast and check it's ok. Be careful working on ballasts, they hold a charge and can be dangerous. Always follow the safety information on the sticker!!

@@YouWrench I have sorted it turns out BMWs dont like non genuine xenon bulbs!! I contacted them and wait for it .............£214 each!! I found a guy on ebay who was selling two genuine ones for £60 got them and worked a treat. Thanks for the advice also got a second hand genuine Ballast which is working good. now both fire up at the same time.
Hi there. What tool are you using? Tone generator based, I'm assuming? Just a bit of personal experience...I've found faulty, intermittent, and broken leads that were still fully insulated on the exterior. Toyotas and GMs are silently notorious for this, especially in between the doors to the body of the particular vehicle.
@@FarAboveDaCloudz I was using a wire tracer with the tone effect option on it Thank you for sharing your experience about broken faulty wires, that were still fully insulated on the exterior it’s hard to imagine but I guess you can come across it every once in a while.
It is an indication that the CONNECTION is solid if no voltage drop. Series circuits drop voltage at each load. A loose or corroded connection BECOME an unwanted load. comment please
Multimeters generally do not come with a 12v setting. The standard setting to use for 12v applications is 20v. It does not matter that it is almost double because the multimeter is only reading the voltage that is present, it is not putting out any power. Also you want a setting that is higher than you are reading to allow for fluctuations. Is you used 12v and the reading came in at 12.2v it would not be able to read it and could, in theory, damage the tool. 20v is the correct and standard setting for 12v applications. Hope that helps 👍
Could I make a point here - you checked voltage on the battery , then where the negative terminal is attached to the body - that will show that the wire from the battery to that point is transmitting power ( would also need checking under load - cranking the engine ). What this would not show is a poor connection between the cable and the body - often where rust or oxidation occurs . If you cleaned the paint off the body there you could confirm whether the battery earth is good through that joint - which is high in the list of culprits for earth faults . Good video otherwise .

Hello and ty but the most important part I feel wasnt covered and so when you find ground fauts how do you fix them?
Awesome video, very simple to understand and follow. Great job my friend!
❤❤❤❤❤❤❤❤❤❤❤❤❤❤😅@@Jesse-qg7hp
Absolutely the best five minutes to a working solution
I dislike electrical issues but I think now I can go into finding a grounding PCM issue much easier. Thanks!
Sounds like your working on a Volvo I'm trying to find the same issue on my V70R
Run a battery cable from the battery ground directly to the alternator bolt bracket etc. this clears up most PCM ground issues.
@petediamond7263 interesting. Thanks!
Finally someone that explains it that I can understand ,thankyou much xx
Amazing, well done. Haven’t done electrical work since trade school and this was the best crash course on finding a faulty ground I have found. Bravo
Great delivery, compact advice, no gibberish, very helpful.
Wow, that's a great visual with the block ground! Thanks!
This video actually shows how to check faulty ground. Thank you.
QUICK-WITTED, You Wrench
Start to finish loved it

both grounds are important of course but the i read the negative is extremely important to be secure. eg chilton auto repair.

Great vid..so once you have established a faulty ground is the next procedure to track the said wire back and locate where the issue is?...specifically i have a renault master 2013...think i have narrowed it dwn to an electical issue...posdinly a ground from one of relays in bonnet fuse.... identifying where though is my next issue..going to look for other vids of yrs and see if i can find. If u got any tips they b appreciate d Cheers ag as in
Hi,is pcm controling voltage on negative wires too?I have a problem with fuel pressure regulator,i measured the voltage at it s harness and shows 0.25 v,with ignition on,if i take ground from somwhere else shows the battery voltage,12/14 depends on how full it is,also i have the p0090 code,the question is,if i take the ground from somewhere else not from the wire that comes from pcm,would damage something,pcm or f. p. regulator?
excellent video!
Very good content, thank you.
Glad you liked it!
very good thank you
YW, your lesson was clear and precise. How do I check whether my car battery is draining when engine is off. With engine off if I take the voltage reading between the +ve and +ve terminals and also between the positive and the grounding terminat, say at 12.14 and after an hour if I check the voltage again connecting the multimeter as before and if the voltage is less than 12.14 does that indicate that the battery is being grounded through some application such as the central locking or the theft alarm or the stereo [ i mean the gadgets that are suposed to be working even when the engine is off' Can you plese guide in this matter with Regards and thnking you for an excellent video
I have the same engine in my van and having several electrical issues. Where are all these grounds located?
Could you use the multimeter on diode setting and touch the negative terminal and whatever spot you're testing? You should get a beep or near a dead short reading for a good circuit. Is there anything wrong with this strategy?
Thank you explained it well and terms I understood
Is this voltage you mentioned in the video here universal like the 5V reference check is across all vehicles?
Great video small and impressive
thank you for the good video i learned a lot
Excellent, subscribed.
Awesome, thank you!
When I do this test on my old Buick, the display on the meter shows only zeros. If I use the POS terminal to do the probing then I get a
valid reading.
Hi, I have a toyota corolla 2017 manual transmission. It draws 140mA with the alarm activated all doors and lights closed. It is the dome fuse that draws 60mA out of the 140mA. It then turns to 10mA when a relay clicks after 20 mins. Is this normal? I hope I get noticed..
What would cause a test light to flicker when put on a ground
Hi there came back home all is well in the car park in the drive way when i start the car nothing no crank but battery strong i just replace the motor starter last year the ground strap in the engine looks new the only bad ground strap i see is in the tale pipe exhaust its all gone you think that will enough to contribute not to start the car?
If the negative lead, to engine shows -12, -13, -16 fluctuating, what's that mean,?
thank you so much clear and precise instructions new sub added
I tried your method of finding a ground fault. The display on the Klein multimeter showed zeros when I used the negative probe to touch
the car engine or body. When I used the positive probe I got valid readings. What's up?
How do you get to replace the strap?
i would consider this a test for an open ground, open circuit... a ground fault would be a short to ground. if were switching across the ground or the positive results would change.
Your opinion was not requested. Ever.
Nick. I formally request your opinon.
@@SicarioDistrepoyour opinion on an opinion was not requested either, but that's what the comments section is for... 😂

I just found out about what a pcv valve is. I just can't locate where it is in this vehicle.
Thanks for this video!
Thanks, brilliant.
You're welcome!
Sorted my son's VW Golf lighting fault out in minutes.
Great information.... Thank you
I will try it , let you know tomorrow.
Issue with your methodology; A ground fault can PREVENT a vehicle from running. Which is possibly why you typically measure in ohms to find a ground fault, rather than voltage
A ground fault does not just have to prevent a vehicle from running... It could be anything from a bulbs shorting out to ground to a bad engine to chassis ground causing a misfire or worse (fire after a throttle cable is used as ground if engine ground is left disconnected)..
I agree ohms should used to measure resistance between two points of contact to find a bad connection or wire.
Volts is normally used to check if the charging system (alternator) is working properly, but this video is a good idea to check for "parasitic drain" caused by devices drawing power while the engine is off
@@OidHunter I didnt say has to, I said it CAN prevent it. Not that it always will, but uts always a possibility when dealing with grounds. Depends what grounding point has issues
How exactly do you ohm test?
Very informative video
So how you test the fuse number 9 on honda civic that so called Back Up Fuse?
Brilliant
Thank you 👍
Wouldn’t an ohm test of the cable do the same thing?
Hello . I’m trying to do this test . When i touch negative and positive battery terminals , it shows 12.6 . And then i do the same with battery positive terminal to xar ground point but the screw and all around it , very rusty . It’s like crumbling metal . I can hardly see the screw . When i touch the screw or surroundings it gives me no reading . Unless i touch the touch the end of the cable . Would bad , rusty screw affect the ground ? Sorry i don’t mnow much about this
Yes, absolutely - rust will stop the power flowing through for sure, and will throw off your readings 👍
Why does an engine mount need to be grounded?
nice lesson!
Thank you!

I have a 97 mustang, when it's cold outside and I start it up the wipers come for a cycle. any idea what could fix that? everything else is great.
My friend's truck will not start and they are telling him it is a wiring issue, they have had it for over a week and haven't found the faulty wire yet. What should he do? He says it turns over but does not start, I say check your starter, but he insists he has a good starter. I said the same thing until my stopped, it gave me no warning, it just went to one click, and so I took out the battery first and had it checked, found a bad cell so I bought that, then it still would not start just the same thing, one click, so I got the starter off took and got another one, it started. How can he be so sure his starter is good? It is trying to start but it won't engage. How can he know it isn't the starter?
Tanks 🎉
My multimeter won't reach all my grounds, having trunk mounted battery. I understand I will need to use wire or cable to complete the connection as needed. My question is, would I see a difference in voltage having to complete the circuit with let's say an appropriate quage wire, vs solely multimeter? Or could I use the power wire closer to ground I'm checking? Hope that makes sense and my wording was direct enough to understand. Thanks in advance 👍
Disregard as after commenting, I scrolled down and saw my question had already been answered. Well the main question anyway. If you have any info on others I asked, would be much appreciated 👍
Hey there! The thickness of the wire you use is not really that important because it is not under any load to simply take a reading with a multimeter. So pretty much any wire will do for extending into hard to reach areas if just doing these kinds of basic ground fault searches. The voltage should stay the same, or near as dammit as again it's not under any real load. Yes, you can use a power wire closer to where you are working if you have to, HOWEVER if you get strange results you will likely also want to re-test with it direct to the battery before you consider it a definite fault as you don't know what circuitry is between the battery and that live wire that could affect the readings. Direct to the battery is definitely the best way to go for ground fault testing!!
@@YouWrench My 95 Ford ranger keeps blowing starter fuses. Do you have any ideas as for what maybe causing this? I check ground to the battery and also the starter wires..Please,Please respond. Thanks
iget a ground fault when I had headlights on for the turning signal but not during the day
2010 dodge caravan
Very simple explanations thanks. I love it.
My resting voltage is at 11.9 on a new battery, new alternator and new wiring. When I go down hill and take my foot off the gas my voltage goes to 14.5 but when I put my foot on the gas and accelerate the voltage drops down to 11.9. Then every now and then when I drive my voltage stays at 14.3.. but most of the time its at 11.9.. Any idea on what could be the issue?
have you solved ?
If I painted the under side of my car is it possible I caused a ground fault if sprayed a screw or ground bolt accidentally?
Hey there! No, that would be very unlikely. Everything that needs to be weather sealed typically is (or at least starts out that way). You have to remember how much water from rain and spray the bottom of the car is subject to. It is possible that paint could have got in somewhere it shouldn't (like a connector for example). But simply painting a screw or bolt head should not typically cause a ground fault. Hope that helps 👍
What about when the ground is further away than the multimeters cords can reach
A good, quality set of jumper cables.
Many thanks I have an issue where my xenon bulb keeps failing due to the ballast failing can this be caused by bad earthing?
Yes, it is a possibility. However, the xenon ballasts can and do go faulty, it's far from uncommon. You could test the earth going into the plug of the xenon ballast and check it's ok. Be careful working on ballasts, they hold a charge and can be dangerous. Always follow the safety information on the sticker!! Best of luck!

@@YouWrench I have sorted it turns out BMWs dont like non genuine xenon bulbs!! I contacted them and wait for it .............£214 each!! I found a guy on ebay who was selling two genuine ones for £60 got them and worked a treat. Thanks for the advice also got a second hand genuine Ballast which is working good. now both fire up at the same time.
What if you use a wire tracer tool and the wire indicates there's a break in the line but there's no visual brakes what would you do?
Hi there. What tool are you using? Tone generator based, I'm assuming? Just a bit of personal experience...I've found faulty, intermittent, and broken leads that were still fully insulated on the exterior. Toyotas and GMs are silently notorious for this, especially in between the doors to the body of the particular vehicle.
@@FarAboveDaCloudz I was using a wire tracer with the tone effect option on it Thank you for sharing your experience about broken faulty wires, that were still fully insulated on the exterior it’s hard to imagine but I guess you can come across it every once in a while.
It is an indication that the CONNECTION is solid if no voltage drop.
Series circuits drop voltage at each load. A loose or corroded connection BECOME an unwanted load.
comment please
why did you get a multi- meter that doesn't have a 12 volt setting for car batteries ?
20 volts is almost double.
Multimeters generally do not come with a 12v setting. The standard setting to use for 12v applications is 20v. It does not matter that it is almost double because the multimeter is only reading the voltage that is present, it is not putting out any power. Also you want a setting that is higher than you are reading to allow for fluctuations. Is you used 12v and the reading came in at 12.2v it would not be able to read it and could, in theory, damage the tool. 20v is the correct and standard setting for 12v applications. Hope that helps 👍
Thanks for you answer to my question. Yes, that makes sense.@@YouWrench
Could I make a point here - you checked voltage on the battery , then where the negative terminal is attached to the body - that will show that the wire from the battery to that point is transmitting power ( would also need checking under load - cranking the engine ).
What this would not show is a poor connection between the cable and the body - often where rust or oxidation occurs . If you cleaned the paint off the body there you could confirm whether the battery earth is good through that joint - which is high in the list of culprits for earth faults .
Good video otherwise .
