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.

[@johnjcb4690]

can you do one for the Keys not moving in the ingition( column steer lock/ ignition Cylinder lock Fix )-

[@flightofthefatman]

@@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

This Guy ROCKS! He explains things in a very clear and understandinable way. He also includes all the steps in the process.

[@Paul_Warren_Wolfe]

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."

[@barkoband4477]

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.

[@dunkelec]

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.

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.

[@markolsen7438]

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

[@JCortez98]

Always wondered about why people loosely say this.

[@wdooley62]

Because they have no idea what they are saying This is properly described as a parasitic draw test

[@ryanhamm2958]

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.

[@MuhNeh]

Wow this is by far the best video I have seen describing how to find a short circuit, thank you so much!

[@anthonyrybczynski5420]

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.

[@Change-Maker]

@@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 :)

[@anthonyrybczynski5420]

@@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.

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.

It's called parasitic draining. Short circuit will cut the fuse..

[@alabastardmasterson]

Atleast he didn't call it a packet

[@mattsilcott1447]

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

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).

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.

[@TheOzthewiz]

The term is PARASITIC

[@cecilg.relation2537]

Not if the amp got damaged.

[@abidurrahman8822]

[@sachinnair1613]

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?

[@JunkyDIYguy]

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.

[@sachinnair1613]

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.

[@JunkyDIYguy]

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.

[@sachinnair1613]

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?

[@JunkyDIYguy]

Sachin Nair yes it is

[@marioabello7137]

[@fieldsofomagh]

[@JunkyDIYguy]

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.

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.

[@hoosenkhan8553]

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..

[@Suhdooper]

Lol no

[@rdeleonnn]

This was very helpful. There should be no reason for anyone to give a thumbs down.

[@juergenscholl2843]

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😏

[@maxwebster7572]

A short to ground can occur after the component between 1 or more loads and may not blow a fuse.

[@williammorace28]

Smart person who wrote this your right!

[@maxwebster7572]

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.

[@juergenscholl2843]

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.

[@maxwebster7572]

Not necessarily. It will be limited by the fuse which is there to protect the wire not the ckt.

Do shorts cause parasitic draw?

[@chrisjohnson4608]

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.
