- When diagnosing a short to ground, the approach is fairly simply. Split the circuit up in to multiple sections, to find out which leg of the circuit is actually at fault.

Great job in identifying the diagnosis and pointing out what a short is. A lot of TH-cam video are calling parasitic draws shorts, which is wrong. A parasitic draw drains, while a short burns things, such as fuses.
Nice job diagnosing the problem using a solid but simple and effective technique. Might add that whenever you have a (new) problem that appears to be a result of other work done on the vehicle, its a good general practice to do a solid visual inspection of the area where the work was done. It's very common for things not to be fully reassembled or properly reassembled when components are replaced. Especially if it required removing interior and/or dash assemblies. Thanks for the video and the tips.
One example of that that comes to mind is when you get a new radiator, then take your ride to someone else for something else entirely, and they tell you someone forgot to fill your new, empty radiator (after that--and it was a reputable place I've gone to for years that I will not slam because I'll probably keep going back--I do some checking after that one and I'm supposed to be the idiot when it comes to practical matters).
This kind of electrical diagnostics ability is hard to find. Nice job explaining it.
it is like true voodoo to me
I COULD ONLY IMAGINE HOW SWEET A TOUR OF THAT VAN WOULD BE. GREAT TIP AND THANKS FOR YOUR TIME !
Thank you very much…. I watched this video long time ago, when you posted first time….. last week I received a Chavy impala with fuse emission 2 15 amp keep blowing, 2 workmates didn’t figure it out and they replaced that fuse….. my service manager handed to me… I figured out there is a short by using power probe and no tone or light on the ground side…. It was not convincing… I remembered your video and attached the light bulb and that helped me a lot…. Found the bank 2 sensor 2 O2 sensor rubbing against the CV axle…..Thank you
Awesome find!
wow, you made that look real easy when its actually a pain. someones lucky to have you around.
Quick and easy to comprehend video, thank you! 👍👍
As soon as you said it had a new heater core put in, I figured the problem would be in that area. If I know someone has previously worked on the car, I would give that area a quick visual first.
Good way to show how to use a test light.
I fully agree with you!
An even easier way is to use a DVOM. Ground the negative lead of the meter and put the other end of the meter to the fuse output (this one will give you continuity to the ground). Select continuity on the DVOM (the one that makes noise when there is continuity). Then disconnect connectors or components until the DVOM does not give out a tone. This way you don't have to be looking at the light all the time you can go by sound when there is no more short to ground.
but have tht think buzzing the whole time? Not sure that's worth it.
@@raynic1173 it's not too bad at all plus you don't have to keep going back and look at the light because sound travels all over but you have to go back and look at the light all the time.
No go. You have to draw current through the test lamp to eliminate "weak" earth/ground through motors, bulbs other "consumers."
The DVOM is not enough of a load. I've had circuits that the DVOM said had 12v but would not carry the load
Both ways are correct, just have to know how to read a meter is all. 0.1-0.3 is normal and you add a point for every module the circuit runs through so 0.6 or 7 is fine if it has the additional modules if not then you have a bad or shaky ground.
Seems like a great idea, can’t wait to try it out.
My uncle (electrician) taught me that trick when I was a kid. Definitely comes in handy. To one’s not understanding how it works it’s very simple at a fuse you shouldn’t have a strong enough ground to light an incandescent bulb. If it lights there is a short to ground in that circuit. Then old fashioned short tracing after that.
Very true!
There could be loads down circuit which will cause the light to illuminate when the short is gone. A high current incandescent lamp such as a headlamp will reduce this possibility.
Thanks for sharing this brother, I’m dealing with this issue in my car.
Greatly appreciated and I’m your newest subscriber 👍🏻👍🏻👍🏻
Been using that method FOREVER, back in the day, I would use a 4652 headlight and because of padded dash tops, I would lay the headlamp on a ceramic tile on top of the dash so I could see the light while pushing and tugging slightly harness.
They call that the wiggle test.
Thanks!
Well…definitely not a video for the average guy who has no experience with mechanical/electrical work.
Thank you my brother you're the greatest I like your calm demeanor
Took me watching videos on these topics for a year for it to finally sink in 🤯
Well, stated, these shorts can be a hard find without this training. Thank you! Liked and subscribed!
Excellent video Brandon.
I Love this Channel!! Good Stuff. Thanks!
Great Job, Brandon!
I've also seen guys use a noise maker of some type in place of the bulb. It would make it so you don't actually need to see the bulb each time. Nice and simple way to show this.
Our updated video has that in it! Excellent use for sure!

Thanks! I'll have to watch that one also.@@JarheadDiagnostics
A semi tractor low air warning beeper also works well . If it is too loud place layers of electrical tape over the audio hole .
Super simple and effective ! I like it!
Damn, you are one of my heroes ;-) . I usually make the sign of the cross when it comes to electrical problems.
Was there a specific fuse cavity that you placed the test light before pulling the connectors?
Brilliant just what needed thanks big love❤
Great short informative video. Where can I get wire diagram schematics
happy watching for reviewing,thanks sir❤❤
awesome! very simple once you lay it out like that. thank you, much appreciated
Great information and video.Thank You!
Same method I used.. Million thanks 🌹🌹🌹🌹
I didn't understand what you were saying until you showed the harness was short to ground on the frame. But I appreciate your information thanks
Love the van!
I like the light bulb trick, I'll be using that!
Great video!!!! Thank you.
great vid i have a problem my right brake light and right turn signal don't work on my 2000 blazer and ideas would be great thanks
Nice diagnostic process.
Very Informative.
Useful video. Thanks
It may have been short but, it was good.
Well done. Thank you.
I have neither the experience nor the knowledge to perform this task. But I sure like to learn new things! Thanks!
MMMMMMMAN !!!! THATS SOME AWESOME DIO MY BROTHER . here is my story i been told to share with you . 1 yr 11 months ago i drive my((((((((((( 2011 BUICK LACROSSE CXS with 3.6L engine)))))))))))))) to the V.A. HODPITAL for my doctors appointment . after i was done 3 hrs later lol , you know this as a vet yourself lol , i came to my car ,when i opened my drivers door ,i heard what sounded like a machine gun going off under the hood .got in car , pushed the starter button and wouldnt crank or start . i got out went under the hood and began investigating . i finally called for a ride and later came with tools to diagnose . i found the # 10 fuse burnt and keeps burning everytime i try to start . what gets me ,everytime i push something on my remote , first connect the battery ,open doors,trunk i hear that very rapid clicking under the hood .i towed to house and i been working on it almost 2 years since , i get frustrated and stop a while then continue eventually lol . i notice when i pull the KR71 RELAY "MITCHELL 1 CALLS IT ,BUT CHILTON CALLS IT KR75 , MY FUSES DONT BURN ANYMORE . THE # 10 fuse goes to a junction that splits into 3 wires that goes to PCM(ECM).THIS RELAY ALSO FEEDS FIUSES 8, 9 ,11, AND 47 OR 46 DEPENDING ON WHAT VERSION YOU HAVE . ! i have never encounter such a terrible problem in 40 yrs my brother . i got a overwhelming good feeling you can help me brother , strange right ? . my CODES COME UP THEN AND NOW AS UO100 AND PO23F . THE DASH ALWAYS SAID ,SOMETHING WRONG WITH STABILTY TRACK AND OBJECT DETECTION . SO MANY strange things about this one brother . any tips or ideas you may have is greatly appreciated my brother ! thank you in advance for your reply ! i have a bluedriver mod and app , powerprobe "the hook" , pp3 and ect-2000 and several test lights different kinds especially found of the computer safe one i got from harbor fright lol ,shows ground and hot , online chilton and pro demand at my disposal ! i have put die-electric grease on a lot of connections fearing fretting the most .i dont want to be a parts changer thats why im still at it , please HELLLLLP ! LOL, I JUST SUBBED ALSO BROTHER !!!
Beautifully done.
Thank you.
I enjoy the video I learn a lot
The light is a cool trick. Thanks
First? My favorite method as well! 5A test light works well. Sweet diag van 😁👍
Thank man! And yeah, it’s great way to save money on fuses. Lol
@@JarheadDiagnostics Keith DeFazio always used a Pulsar tool for shorts, but they are hard to find and kind of bulky
@@JarheadDiagnosticslolol you must be joking right?! Lolol fuses are pretty dang cheap I bought a box and I have constant electrical problems and i still have a few dozen left.... What is a pain in the asd is the TIME it takes pulling fuses.... At least that's how I feel lol
Hey man wondering if you can shed some light on a situation I’m having in a 2009 Acura TSX while installing my aftermarket radio my constant power cable made some contact and all I heard was the spark and now I have no constant power all fuses are good in the car and under the hood any info would be greatly appreciated thanks in advance
nicely done!!!
When you buy it from your website does it come with the light and the pins?
can anyone please help me
so when you go wiggle wire harness and find the short does the bulb dim or go out completely as ive watched two vids of this method and both had light dim when found and other the bulb went out seen here?,i couldnt figure out why the bulb would go out because wouldnt this create a series circuit thus dimming both bulbs (pretend its a headlight circuit) as they now share the same circuit?
Thank you for the video
Great video.
i want this to be my go to method but a few things confusing would you be willing to make another video when you do another short to ground?
Ooorah outstanding work
We have a trailblazer that has a issue with the rear hatch, hatch control module is clicking and won’t allow us to unlock by remote. I replaced the module with a brand new one and it’s still doing it. Think I have a short to ground somewhere ?
Subscribed and rang the bell !!!! Thank you!!!
Absolute legend. Can you recommend someone to do this level of diagnosing in San Antonio texas?
nice find
We were taught to do a half split on the circuitry to simplify the job. Basic trouble shooting here. And hint to save fuses while doing it, haa Good work, thanks.
It's shorted out, all the way to the ground post , isolated , no ground hooked up. And I have 12.6 to ground post of the car frame , all the fuses is 12.6, alternator has 12.6 volts on the terminal side and the ground side. I reversed the process isolated the positive and of course it has ground all the way through. I pulled fuses and relays and no voltage drop. The only thing I did not unplug is the ECM. So I have closed relay or a exposed positive wire touching the frame. But I have a power probe 3 and a signal tester for breaks. It's a chrysler sebring 2006 2.7 litter . Be for the wife broke down the battery light came on, wife said smoke came from the passenger side of the engine.
thanks for the video
I pull up the fuse chart in service information or owners manual. The service information may be more complete in one chart as to what that fuse powers.
The chart or tables show the fuse number, fuse size, and everything that fuse powers. What items are in the dash and go from there.
Exactly the approach I use, after deciding which circuit it is.
So does it mean that the harness of the side impact sensor on my car was off of the sensor and grounding to the to the frame?
Thanks for the excellent video. When you probed pin 7, was the lead on that probe just jumped from one side of the test light? Also, where are you located?
same question?did he jump from the test light or hook up to power from one side of the light then when he probed #7 that should be 12v power it lit up the light because the short was a path to ground.i want this to be my new method for locating shorts but need more info do you know any other vids that use the same method?
great info
Can I use it to trace the ground on a Diesel Forklift 24 volt circuit?
Nice Diag!
Good video Thx , i have an old voltmeter with a bulb taped on it so can use the leads an of course working voltmeter lol an a pencil probe that pretty much covers anything anybody needs
You can set your DMM on DC voltage in place of the light. And as long as there is a short to ground it will show the circuit voltage.
True. But a light is good, simple, and easily seen from a distances.
DMM input impedance too high; you'll read ghost voltage if there is leakage in circuit. Without a load, you might waste time following leakage paths. If you choose not to use a ballast lamp technique, then select an appropriate shunt resistor to substitute for fuse, and use DMM to measure voltage across that.
Only if all other loads are removed and there are many on this circuit it's a fake vidio
Is this safe to do always and wont fry something else? I have a blown 15A ECM fuse where thebwire goes to the ECM. Fuse blows anytime the door is opened (car wakesbup I guess). Just dont want to fry my ECM or other components using this method. But im having trouble finding where to search next!
So if the light comes on, there is a short to ground? Key need to be on to accessorie or off or twat? Thanks in advance 👍
Insightful
Good stuff.
Link to the tools used to connect to the fuse box?
Hi I have a utv that is blowing a fuse intermittent what's bast way to find it there is lots of things running on this thanks
I've been using a sealed beam light for decades. My shop foreman convinced me a test light is adequate as long as it's not LED. I found out this week that it is NOT adequate when looking at a bad relay. I put two supercharger coolant pumps on with same results until I went back to my sealed beam. It would light up my test light, not the sealed beam. Quite a few choice words fer that one lol
As soon as you said new heater core the thought of pinched or crossed connection in the glove box was my first thought ….but being only shade tree level experience only ,idve gotten frustrated if I didnt notice the issue quickly ….😂
A blown fuse and a buzzer soldered to it works great to find a short too.
That's a great idea.
i'M BUMMED rADIO sHACK ISN'T AROUND FOR THE SHORT TRIP TO GET COMMON ELECTRONIC COMPONENTS. nOW IT'S A DDRAG
I have a electrical problem on my 02 Honda accord and hope maybe you can help my car out with this power pull
Lol, I am clueless here. I have a throttle issue that upon testing the harness. It shows short to ground. But no fuses are blown, and the relays are fine. What would you suggest I do here to the short to ground.
Damn!! New subscriber!! I have a 95 Roadmaster and the horn blows when the fuse is in and it goes off when I remove the fuse. It blows constantly while the fuse is in.
Very good
Had an issue on a 89 chevy truck. Tried to find it by removing fuses no luck there finally tracked it down to a worn positive battery cable shorted to the battery tray intermittently draining the battery overnight.
Do you have a video of a 2008 ford explorer xlt of the pcm mini 39 fuse blown I narrowed it down between the mini number 39 fuse to the key on the inside as soon as I turn the key on the 15amp number 39 mini fuse blows and I can't find the short I'm hoping you will be able to help me out
Hi Brandon love your work probably a silly question but does the circuit have to be active or should the bulb never light
How did you wire up and make your test light that can be put in the fuse locations????
a light and one wire end to one of the fuse side and the other wire to the other side .
Hi, have 2006 jeep liberty was working fine ,took keyfob from pants pocket to unlock it and the unlock button seemed stuck/depressed position ,wouldnt unlock , checked fob battery {good] used key to unlock and tried doorpad switches [didnt work either ]....would a stuck on position create a short in the power locks controller ? I then checked 20 amp fuse and it was blown replaced fuse and activated locks they work but when using unlock it blows the fuse , If i plug the test light into the fuse holder and try each switch to try and isolate def switch/motor or is it probably the wire in the door harness chafed /boken and grounding
Good job thanks
Excellent diag cool
Not only the easiest but the best way. If you don't have a test light you can make an emergency light yourself. You need to have a wire long enough to be cut in two. The other materials are already in the car. You can use the blown fuse and any working light bulb in the car.
Your a liar
2009 infinity g37x engine fuse 15 and coil constantly blow out
Where should I start my test
Thanks
hi Brandon, I got an old '71 VW and my negative cable on battery terminal feels warm, really warm to touch and the terminal is hot after I attempt to start the engine. Does that mean I got a short-circuit so where or just replace the ground cable-wire? thx
Excellent video brother! I also use this method and it works well.
Bs only if its the only load and it's not
@sartorst3376 Care to explain yourself further? Perhaps you know something we don't. What I can say is that I've used this method to successfully diagnose a short to ground on numerous occasions, as have many others. At the end of the day, it's tough to argue with results.
Thanks.
Great reminder to divide and conquer electrical diagram
Interesting and informative, at least what you could hear of it -
What is the program or website where you get your wiring diagrams?
I am curious. You said there was a short showing on pin 6, 7, and 19. When you have multiple possible short locations like this, what allows you to decisively say that pin 6 is there error circuit? I only ask because I am showing like 7 pins on a connector with a short to ground, so does this mean they share the same ground? How do I figure out which is the circuit in the connector with the short to ground?
Bi or try type of curious? Asking for a brother that commented above…
