How to find a short with a light bulb!

[@djosbun]

These types of diagnostic videos are THE BEST for those that are new to electrical troubleshooting. A+++!

Seeinga mock-up on a beac bench of this car setup and how the test light works in this situation would be cool like a small mock up of what went wrong so you can track it out of the car

[@secretsquirrel9722]

Great run through of using bulbs instead of 1000 fuses, haha. I noticed 2 things only another tech knows the pain of. 1, part way through, I noticed the blood on your knuckle from pulling plastic trims, lol. 2. As soon as you traced it to the A-pillar connector = the old sun visor mount screw through the wiring! Hahaha.

[@janico76]

Jake I enjoy all your videos. I like the way you breakdown your diags. and have the patience on the camera to show us your way of doing a diag. smoothly. Please keep up the videos coming.God bless you.

[@spelunkerd]

I loved your clear, logical thought process to trace a dead short through the BCM.

[@4aautodiagnosticsandrepair199]

Great work! I appreciate you taking the time to demystify by explaining the diagnostic process. The details you provide to narrow the issue through circuit elimination are awesome . So simple watching you do it. Though more difficult in reality. Thanks for making it look easy and simple to understand.

[@wshamroukh]

I'm addicted to your videos since finding your channel..., when you kept one lead of the bulb to the 12v pin on the bcm connector and removed the other lead that was connected to the ground bar in the dashboard and started tapping into other circuits, it took me a while to figure out what you did there and why?? You did that because you were looking for a cirtcuit that is shorted to ground so u kept one lead to 12v pin while the other lead if it finds a ground or a short to ground it would light up... Brilliant video as always....keep it up man

[@meblake7359]

Thanks for the explanation because I had no clue where his first wire was plugged into. That's awesome!

[@joeandgod1]

I've diagnosed a short exactly like that, they screwed the screw into the wire. I used the power probe ect3000. That tool has helped me find me all kinds of shorts.

[@jonathanclark7155]

Your a beast brother, made that look easy. Great explanation on using the light to find the grounded wire, and verifying the short was gone after the repair was performed! Love the channel man! Ill be binge watching all your videos now haha

[@arthurburke1044]

Up late,Stayed up till you found that short ⚡️⚡️💥

[@Mr2004MCSS]

That was a great case study. You did a great job of breaking the system down in order to find the problem.

[@EHUE-kf4ey]

Very straight to the point. Note, I added a buzzer & a bulb to another test light for out of sight of light bulb work. Thanks a mil.😎

[@aamechanic8154]

I put banana jack ends on my different amp test lights. I find it alot easier for hook up and secure connections. Great job as usual👍

[@darielbrown9823]

I always wanted to learn electrical. Keep putting your videos out there, I learn a lot from you,keep up the good work.

[@HSH11]

Thank you! That was really cool. I really appreciate the time you took to show your work and the process of chasing a short. You're really good at explaining your process. Kudos. I wish I knew electrical the way you do.

[@jakeman1968]

This video helped me find the short in my vehicle. The light bulb trick is a great way to test things now that I know. Thanks for your videos.

[@scratchercatcher6760]

Thank you for very detailed video. Very helpful.

[@mikechiodetti4482]

Good Job! I've seen that problem in older Ford Vans when a steel fence/wall was installed between the driver/passenger seats and the rear cargo area.

[@CraneofBoulogne]

That is a great how to video. I greatly appreciate your efforts to explain so many things in detail! I wonder if those that do not offer reasonably good explanations do not do so because they simply cannot do it, they are incapable of explaining what they don't understand themselves.

[@SuperLalo213]

Best video I've seen, on finding a short. Thanks.

[@grahamwatson451]

Where does it show how to rig up a test light in the video?

[@frugalprepper]

Nice video. I am not against cutting a wire in the harness to break the circuit in half for testing as well if there are no good connectors around to do it. I can always solder it back together. It is always nice when they aren't intermittent as well. Those intermittent shorts can be real fun ones.

[@delskitchiwa]

Chapeau my friend! Thanks for your patience to explain all these.

[@elwoodwilliams5665]

You did a great job finding the short. That was crappy work done at the factory. Another example of how Nissan quality has gone down. My wife & I used to drive Maximas & loved them. Now we drive Hondas. Keep up the good work & videos.

[@DependableAutoTruck]

Great video i really enjoy the way you do what you do simple easy to follow really helpful thanks for taking the time to help us

[@swolath]

You look like you know what you’re doing. Very impressed

[@Nine_Finger_Wrenching]

Man what a great video!! I’ve got an old FoxBody project car I just bought. It’s got a partially installed new body harness. The ecu was fried so I sent it off for repair. They’ve given me a list of pins on the connectors to test before I hook ecu back up. I’ve been trying to find a good procedure for doing that.

[@mrteaman]

There's nothing more satisfying than watching someone do something they're good at and also seems to enjoy the process. I could legit watch you work for hours. And you're good looking 😉

[@billyyoder8171]

Thank you Jake. Good job. Have a great day.

[@waqasazmat81]

Thanks, great refresher about short to ground and how to use a light bulb to find a short. (y)

[@rick5515]

Great call with the glue shrink tube. Seales and holds it all in place from the elements so as to not corrode. I worked for Siemens running assembly and test for flow meters. They all go into exstream environments. Not that a car will be there but anything to prevent problems is a plus. Thank You for another learning experience.

[@Capesthorn]

Great video. Learnt a lot.

[@simonedwards5401]

Excellent find love your diagnostic approach

[@hhn2002]

Quick effective diagnosis. Way more interesting than I thought it was going to be. Great job😼👍 now I wonder how it got like that…hmm

[@heyitschinoable]

Right on! 😎 this is why i love electrical issues, although it can be very frustrating at times it can be very fun after it all

[@ashercohen4739]

Thank you very much, the way you arrive at the fault is the main thing

[@luretrixster]

Really useful, now i'll take my bulb and start the journey on my old Pajero

Excelent diagnostic finding electrical problems is not easy.good job thank you for sharing 👍

[@HOTRODRICO]

car was probably in a accident and when replacing the side airbag the guy pinched that vanity mirror light wire ... good find... not sure if you have a video on how you made that test bulb soldering it and wiring it up, and what different amperage bulbs you use and when or how to use them, would be beneficial to learn from ... thanks, cool video

[@CHIBA280CRV]

Very informative , it will help look for my issue.. thanks 👍🏼👍🏼👍🏼👍🏼👍🏼

[@michaelr.williams8176]

To find if you have a ground in your wireing system. Take off your hot wire coming from your battery hook up your tester one lead to the. Hot terminal going to vehicle. Then to your hot on your battery if it lights up you have a ground. In your wireing system

[@gregs2029]

[@ivandrago2557]

What a knowledge👍👍 when I saw Ivan pine hollow diagnostic on your channell got a confirm. If I undedstood the wire was shorted to plus

[@marcosmateo8439]

Great Diagnosis!! I feel like someone replaced that Visor and wasn’t paying attention and smushed those wires together.

good job. i like the way you go about it the best way

[@wastedcentury1805]

I have the same type of issue, an older Infiniti with a short to ground that instantly blows the 10 amp Room Lamp fuse. No ignition required. I can't find the energy to trace it so far, once I realized that circuit is linked to all the overhead interior lights plus the trunk light and elsewhere. Maybe this video will give me an idea and jumpstart the motivation.

[@chrisb7528]

You actually used the word short properly. 90 percent of short videos aren't shorts and the idiots in comments praise them .

[@chrisb7528]

@@autodiagyt Yes I try to explain to people all the time what an open is. Most youtube videos on so called shorts ends up being their dome light is on, lol.

[@2dArmoredDivison]

really great troubleshooting, I like the isolation diagnosis using the diagram. What is the part number of the solder tool, is that propane?

[@autodiagyt]

It’s butane but I’ve retired it and I use battery powered one. You can find it and the stuff on my Amazon store

[@GroundedDiagnostics]

Great tip about the tiny bits that stick out when soldering wires together. I have always thought soldering to be the best . some say you should never solder some say always solder. Have you ever given the shrink n seal butt connectors a go. Not the ones with solder inside.👍👍Another great video 😊😊

[@PineHollowAutoDiagnostics]

@@autodiagyt 100% agree! If the harness is properly supported there shouldn't be much movement or vibration anyways. GM is the worst at factory harness supports lol

[@GroundedDiagnostics]

@@autodiagyt I will have a look for that video. great answer I found an old relay in the garage that I soldered wires directly to decades ago On the advice of the auto electrician that sold it to me. The wires were still on there solid as can be and I never had any starter problems from installing it to scrapping the car years later. It was a 1984 GM Vauxhall cavalier diesel and that sucker vibrated like a jack hammer. That's why he suggested soldering the wires direct lol👍👍👍

Judging by the name on your hoodie I’m guessing your a sand mountain guy lol, I too am a sand mountain resident with a diagnostics shop in RBC great vid very informative electronics can be intimidating for some but a good diagram and logic most problems are really simple

[@darrellsdiagnostics9207]

I’ve been doing business in RBC since 2009 , been in the automotive trade since 1994, I’m always trying to learn new methods, techniques, thought processes, I’ve enjoyed your vids, I worked at a local ford dealer on the mountain for years , before I opened my shop in RBC, I would do a lot of diag , programming , and Pats keys for the local used lots I’ll bet we know alot of the same people.

[@charliemorton7644]

Excellent knowledge & diagnostic skills & Great job!!! I have a fuse that keeps blowing for my PCM emissions control & it has blown two fuses. Now, I'm wondering what should I check first to correct the problem. Does this mean I have a short somewhere or is something not grounded securely?

[@robertmobileman8304]

good job , great step by step diag , thanks

[@JD-vs6is]

Can you make a video explaining what equipment is special for you?

[@advancedleveldiagnostics]

Excellent Video, really enjoyed!

[@luiscruz-no3ib]

The bulb works fine, but you have to look at it to find the source. A low amp buzzard works better. Not having to look at it helps a lot😮

[@bartscave]

Good diagnosis!

[@badrubakari1418]

Great video. Have a question; when you started probing the connector on the dash, you had one wire stationary and another wire which you were moving around the different circuits. Question is was the stationary wire on 12V? I think this could also be done with a multimeter on continuity and beep mode. Based on your experience, are most of these fault ussually a short to ground, faulty module/connector?? Also , how did you make those probs. A video on that would nice. Awsome content.

[@autodiagyt]

Yes wire is 12v, for continuity beep test every device would need to be disconnected to have any accurate test. With a bulb and volt meter I can tell if it's dead short to ground or grounding through a device. My new video about this testing method goes into more detail about this.

[@adelalshammary109]

very smart way

Whats the bulb number and socket on that 10 amp test light? I like that. I have a few that range from 500millamps to 4.5. That one would be nice to add to the arsenal. Great diag brother 👍

@@autodiagytsounds good 👍 thanks

[@EATSLEEPFARM]

@@autodiagyt Thank you sir!!

[@dzljon]

Light bulbs are a great idea

[@dieselfixr]

Looks like the body module is ground side controlled. Because the power from pin 131 can't make contact with pin 129 unless the body module is allowing power to it at all times.

[@sheerwillsurvival2064]

I had too watch again. I remember thinking they basically wired the starship enterprise into that one fuse 😱

[@JonHannah-q5b]

OK thanks I'll keep watching

[@markfisher1716]

Great video but would you explain how you rigged up your test light? Thanks.

[@autodiagyt]

It's just in series with the circuit.

[@RichardWright-ty8gr]

How well would an amp clamp work; first around a wire bundle followed by individual wires to find the light bulbs 2 Amps. Also helpful might be a slow pulsing current through the light bulb to assist in locating the short with the amp clamp.

[@billluzius3778]

SMA Auto had the same one

[@lukula2934]

That was more helpful than many vids out there. I was wondering where you get reliable diagrams. Did you have a scanner that can access them? And is it for pros only? My issue with this kind of work is getting past the fundamentals. Knowing what a BCM is or Battery saver relay is, etc. So the test light is connected to reliable ground and acts like a fuse to still protect from further damage? So for me its knowing how to translate a diagram to the actual circuit with certainty. Fixing a known issue is always the "easy" part. But I'll admit to being a "deer in the headlights" when I open a panel or read a fault.

[@gala83filmstaylorg7]

Great job!

[@magid5441]

Very good job

[@CodycoWeb]

I use non-insulated crimp barrel (butt) connectors when I do solder wires. They work great to secure the wires while soldering and also eliminate the stray wire poke issue. Not all wiring can be fixed by soldering, high vibration areas, on those I use them with heat shrink and sealer only as they are strong enough to hold the wires by themselves. You can get bags of the 3 major sizes of non-insulated crips cheap and they work well

[@PaulCTownsend]

Great job thank you.

[@lupedel-r5p]
