I need help in my 2018 Camry, I must of shorted out something when tapping into a wire for a led light, now the lights around my radio do not come on and all other interior lights are dim, but everything else works as it should including the radio, any advise would be great.
@@gman20031 Check no fuses have been blown. If not do a parasitic draw to find which circuit is affected. Then obtain the wiring diagram for that circuit and then isolate the problem area by voltage drop testing. Dim lights means that there is resistance on that circuit which is taking voltage away from the lights. If the fuse for the lights that don't work is blown and you replace the fuse with the correct rated fuse and it blows again then you have a short circuit on that components electrical circuit. You will need to do a voltage drop test as well using a wiring. diagram
You can also do the same thing by using a small 12v bulb with leads and alligator clips attached in place of the meter connected between the battery minus post and the ground terminal wire you have first removed. It will light when there is even a tiny parasitic current flowing. The brighter the light then the more the current draw. If you want to try it out then hookup the light as described and open the glove box or a door. The light will get very bright. I learned this from an old mechanic. Be careful out there.
Junky you are a star. Best video i have seen for my problem with a fuse that keeps blowing. Very precise and interesting. Thanks for saving the day. All the best Duncan Cornwall UK.
Excellent video, thank you very much for the help. As for the "misleading" title, "short" is a commonly used term to describe current not working properly - i.e. making a complete and proper circuit. All of you commenting that the title mislead you, when you say something is "awesome," is it because you're in awe of it? When you say something is "cool," do you mean it's cold? Don't even get me started on the word "sick."
Excellent content! This is the first automotive content creator I’ve ever heard with such good knowledge combined with an ability to explain using simple and concise terms.
As a general rule when you use the term "short" you will generally see smoke or find burnt wires. If your radio is still drawing power it is likely you have a switch that is malfunctioning. A short means negative and positive have touched each other
I'm a automotive tech. And more specifically an electrical diagnostic tech, smoke and burned wires are not common symptoms of a short. In fact, I've only seen that happen 2 times. Second, many components can short internally, and cause a parasitic draw. (A radio for example or modules typically) the poster of the video should have mentioned this. The title is misleading. A short doesn't nessicarily mean ground and positive have touched. There's a few other types of electrical shorts. Stop spreading misinformation.
@@ryanhamm2958 any idea why my Ford Fiesta has a circuit motor pump failure? Keeps blowing 30 amp fuse something is shorting out somewhere but I can not find where 😌
Nice job with the video and the explanations. From the looks of the shorted / melted wires and melted plastic this car owner was very fortunate to have not experienced a fire.

Very well narrated and quick to the point. Great camera angles and quality. Also very creative solutions for troubleshooting. I like the tips for cars that need to enter sleep mode. Tricking the computers by closing door and hood switches and using the remote to lock the car.
Hey Junky. You made a great video. I have that problem and it is a pain in the ass when my truck won't start because of a dead battery. I did what you said and found my problem. Thanks a million from Ontario, Canada.🍁🍁👍👍
you are by the best instructor ever i have seen many videos that are short commings in information thank you for taking the time and going over the procedure and explaining in detail what you are doing and what is going on i definatly will be share your videos.
I think it is a bad video because the tech should also be considering why the amplifier is putting power to the sub with key off overnight. With the key out the amp should power down and kill power to the sub as the mosfets shut off. The radio output to turn on amplifier should also be tested to see if it is shutting off or if the amp is bad. Maybe the short at the sub burned a transistor in the amp and now the amp will not power down properly. More testing required for guaranteed workmanship.
@@anthonyrybczynski5420 thank you Anthony! Super new to this and your comment makes complete sense. I have now learnt the basics from the video and a little more from you :)
@@Change-Maker look for videos using a bell telephone tool to find the short. You pull the fuse and induce a signal into the circuit with a short. Then there is a second tool that makes a tone, you run it along the harness until the tone stops, then open the harness. You can also buy a similar tool made by power probe. It comes in the power probe master kit #5.0. From what i hear the bell tool works the same just people find the bell tool cheaper.
Loved the content, presentation, and lessons learned. I ran the video at 75% speed making it easier to follow especially as there's a lot of great information shared. Thanks again.
Another common problem with Radio Installations is the Service Tech uses the Clock Hot Always ON instead of switched HOT and is OFF when the Key is OFF. Great Video. Good Job finding that Fire Hazard.
A short will typically pop the fuse. Short to earth before the load. At the start of video you are testing for current draw which will cause flat battery issues. The title is misleading imo.
Whew, glad I found your video again. Just look at some of the others and , well, I'm sure you already know. Thanks! I put (not physically) a thumbs up on the good comments here. I'm going to say this and I say it humorously and with love In 1983, MTV music video shorts hit television. It was a rockin' and rollin' good time! There were videos that were interesting, one curious one was call Fish Heads (eat them up, hum). It was a riot. But there's one, also, had the band members moving real fast and wore gloves similar as you wear here. That song was a riot and a barn burner, as well. Your gloves and the fast forward remind me of that video. Love it! You're an icon. Keep rockin' those excellent, clearly and simply explained videos. (Too many adjectives?)
So I'm going to try it out and see how it helps my car, its been 2 days trying to search what makes my car battery drain, my energizer portable jumper start won't work because of that short circuit. Thanks for this tip!
Great video, it was very descriptive. I had a small question, I have a fuse that keeps blowing (its the tail fuse, controls the tail lights, parking lights, and the license plate lights). I found the problem to be the parking lights, since the fuses stopped blowing when they were disconnected. What's the next step?
the only reason why a fuse would blow is flowing too much current through the fuse. Either someone installed brighter light bulbs that require more current than regular light bulbs or splicing the tail light wires to draw power from it to power up something else like extra brake lights or reverse lights. Assuming it's not the case in your car or you don't have a faulty body control module, i highly recommend to check the wiring harness for any shorts. Looks like You have a short to ground. possibly anywhere between the fuse and the tail lights on the live wire that goes to the tail lights has a damaged insulation, that rubs against the chassis.
I did install aftermarket headlights that have CCFL halos, but on all the reviews on Amazon, they said that they work fine and don't require additional power. How would one go about checking the wire harnesses? I have access to a wiring diagram, and I located the grounds for the tail lights, parking lights, and the license plate lights.
you said you have found the problem to be parking lights. there're 4 parking lights. 2 in the front, 2 in the rear. Narrow it down to to see which one of them causes the fuse to blow. Rather than blowing a bunch of fuses as you test, you can buy a re settable fuse circuit breaker that goes in to where the normal fuse would go in. so you can manually reset the fuse every time it blows out. Once you narrow it down to the defective parking light. Then start checking the live wire that comes to that light. check the parking light switch too. Sometimes they short out inside.
Junky DIY guy thanks. Actually, a set of 25 fuses only cost me $5 so it's really not worth it. Also, I found out that the problem is the passenger side parking light. If I unplug that, the fuse doesn't blow. Should the next step be to try to trace the wire from the lights to the fuse, if that's even possible?
Well Done Video. I Would Like To Add: The Battery Should Be One of The First Things You Should Check When You Purchase a Used Vehicle. Make Sure The Battery Is The Correct One For The Vehicle.
The second way is the correct way to diagnose a draw on modern cars. Pulling fuses is not recommended anymore, although it is still my preferred method.
Your videos are great very informative & very easy to follow. Which is great for us DIY mechanics.This has gave me more confidence with my new multimeter. Many thanks for taking the time to post this. 😊👍👍👌
Maybe I missed something, but how would shorted subwoofer speaker wires cause a battery drain? Or any speaker wires for that matter? I don't think they can, they're post-amp that's switched off when the vehicle's off.
Your're looking for a parasidic draw not a short.Parasidic put a drain on your battery. Shorts usually blow fuses. You have two kinds of shorts for example power to power shorts which doesnt normally blow your fuse; ifyour press your horn your indicator light comes on. Shot to ground ground most definately blow your fuse since there is no resistance.
Some German cars require reprogramming the ECU if you disconnect the battery. So sometimes this is the only way you can find a short unless you wanna spend big$$$ reprogramming the ecu.

Junky DIY guy: I have a question. How do you chase the wiring harness on the radio if there is a short circuit . Do you have to remove or uninstall the radio from the dashboard ?
Disconnecting the negative battery on some newer cars such as VWs and Jaguars could cause a loss of throttle settings and a dealer scan tool is the only way to get the car started.
This is not true one does not need to re-align or do basic settings in a new Audi or VW when the battery is disconnected. The ECU automatically does this all you need to do is leave the ignition turned on for a few seconds after the battery is Re-connected..
The fuses actually do NOT protect the components, their functions are to protect the installation and avoid electrical fires. (1.13) 1 - If a component draws too much current it already is bad and the only thing left to protect is the wiring... 2 - If there's a short to ground causing higher current flow than a component can stand, this short will take place before the component and the high current doesn't even flow through it. Think about it😏
max webster If the short takes place after the component current flow will be limited by the component itself to the amount the circuit was designed for.
Great video!! I have a 1980 Dodge St.Regis that has a short somewhere. I drove it a long distance home after buying it and it kept draining the battery. It has been driving me crazy.
For prolong storage of vehicle ( no driving), it is useful to do one or both of this, 1) a manual 'disconnect switch' to positive battery terminal 2) have a solar panel ( getting Sun) that trickle charges the battery while in storage / parked. But also check for weak battery draining ( not holding charge while disconnected).
No, a short is an unintended path to earth. If this happens it will create an over current situation and blow the fuse. The fault with the sub wires in the video would not cause this fault with these symptoms. It would put an amplifier into protect mode, not drain the battery.
Thank you for sharing your knowledge. I have few questions if you could kindly share your input. 1- At sleep mode meter is showing 0.05 amps, is it normal for a 2019 lexus nx300 (SUV)? 2- I see spark when i touch the black color lead to the battery terminal (-ive side), does that mean i have a short? i don't have any blown fuse. 3- What things you would recommend to test on a car that went thorough flood water?
Thank you !!!!! I followed your approach and located the source of my problem. As luck would have it, it was the absolute LAST of 27 fuses that I pulled!!!

It's called parasitic draining. Short circuit will cut the fuse..
Atleast he didn't call it a packet
Parasitic draw is a short circuit most fuses are at least 10 amp fuse blows from overload and many other things. Just my opinion
Although I rarely see a fused circuit that will get this hot as the fuse should burn b4 wires in my experience
@Roberto Mundo tries to correct him.... fucks up lol

2 - If there's a short to ground causing higher current flow than a component can stand, this short will take place before the component and the high current doesn't even flow through it.
Think about it😏
A short to ground can occur after the component between 1 or more loads and may not blow a fuse.
Smart person who wrote this your right!
Correct in a basic ckt unless the short occurs after the load, spikes and takes out an IC or other sensitive components or cause shunting.

If the short takes place after the component current flow will be limited by the component itself to the amount the circuit was designed for.
Not necessarily. It will be limited by the fuse which is there to protect the wire not the ckt.
Great video!! I have a 1980 Dodge St.Regis that has a short somewhere. I drove it a long distance home after buying it and it kept draining the battery. It has been driving me crazy.
Fantastic thanks
Very clear and simple narration. TNXS
This is not a SHORT. This is a parasitic loss. Completely different things. Video title is misleading.
Wires burnt together is a short. Don't know where you found parasites
Thanks for saving me time.

While I’m not disagreeing with you don’t short circuits sometimes cause parasitic draw? 🤔
Thanks, saved much time.
Wow this is very helpful thanks.
For prolong storage of vehicle ( no driving), it is useful to do one or both of this, 1) a manual 'disconnect switch' to positive battery terminal 2) have a solar panel ( getting Sun) that trickle charges the battery while in storage / parked. But also check for weak battery draining ( not holding charge while disconnected).
Speaker cable had nothing to do with the voltage drainage period
Yeah, probably blew a transistor in the RADIO because of shorted output
Typically a larger wire is required to drive your subs. I would replace the wires with larger. Thanks for the video.. well done
Dude! I never even thought about doing that. Thank you so much.🙏🏾
Why is the title of this video how to find a short? You're not finding a short, you're finding a parasitic draw
Do shorts cause parasitic draw?
No, a short is an unintended path to earth. If this happens it will create an over current situation and blow the fuse. The fault with the sub wires in the video would not cause this fault with these symptoms. It would put an amplifier into protect mode, not drain the battery.
Thank you for sharing your knowledge. I have few questions if you could kindly share your input.
1- At sleep mode meter is showing 0.05 amps, is it normal for a 2019 lexus nx300 (SUV)?
2- I see spark when i touch the black color lead to the battery terminal (-ive side), does that mean i have a short? i don't have any blown fuse.
3- What things you would recommend to test on a car that went thorough flood water?
1) 0.05A=50mA that's quite normal for me
2) most car does that, i guess that is because the circuit has capacitors, hence the sparks.
That works on old cars new cars have body control module this not going to work home boy
OkY so How about you explain why it won't work or a how to on vehicle's with bcm?
Lmao wtf is a home boy, G?
Thank you !!!!! I followed your approach and located the source of my problem. As luck would have it, it was the absolute LAST of 27 fuses that I pulled!!!
donna:
lucky you!!
Often it works out like this. ...hardly ever the first one😒
You explained it very well I understood everything you said excellent video thank you
Your diagrams are perfectly awesome.
Good , simple and straightforward troubleshooting.......
excellent. You are the best of the best. you explained very clearly
The best tutorial on UA-cam
One of the best video 10 out of 10 Amazing super duper no words thanks keep it brother
