the minute you turned the key on and the chime was at full blast I knew right away there was an aftermarket amplifier in the vehicle. also there was an LC-1 volume knob on the knee bolster, the wire at the under dash connection was what the audio shop used as an "amplifier turn on (remote wire)" and it SHOULD have been installed on a switched accessory wire (they installed it to a constant 12v instead causing the aftermarket amp to stay powered on) you could have put an amp clamp on the 4 guage wire under the hood and seen the amp draw. the boxes behind the radio were called line out converters. they are installed at the factory radio speaker outputs to drop down signal to RCA level to go to the aftermarket amplifier, and there would be speaker wires tied into the speaker sides of the wires that came from the amplifier. Also you should have noticed the large blue 4 gauge wire on the driverside firewall. That will have been connected to battery positive and ran to the amplifier. (probably mounted on back wall behind seat) great video again dude!

Superb Job! Clear and logical troubleshooting and a nice clean repair. Job well done!

OZ YOU ARE THE BEST, YOUR DIAGNOSTICS BRAIN WORKS LIKE A CHARM. YOUR APPROACH TOTALLY LIKE A GENIOUS ALL THE WAY.THANKS

I have that same wire by the pedals. I'll look into this. Thanks, man. Amazing work.

Absolutely superb job, Oz!

Outstanding work! I like that you did nothing fancier than use multimeter and pair of pliers to find the culprit for this one.

It suck’s from the customers prospective; he didn’t know the prior owner hacked it up. Hopefully it wasn’t a flood car. Great diagnostic work tracking down it’s draw.

your thinking process is exceptional...hi score on critical thinking skills...you rock bro...

Good job following the source of drain!

Came here from the IJ channel. I'm happy to hear you got your temp injunction, keep fighting the good fight.

Awesome fix.

Professional work 👌

Excellent fix. 👍👍

Good morning brother, thank you for your video, I went through the same process and found it was a parasitic drain/short in my steering wheel. But what I really need to find now is the link for those battery terminal jumper clips that plug into your kline tool. Again Thank you for your help bro.

excellent work.

man, i would have never been able to dig that out! Deff need to train myself into the Mitchell system.

Great job

My son's Chevy Tahoe is having the draining battery issue trying my best to figure it out. Great video thanks . I don't see the subscribe area

Good job 👍

Where did you hook other lead to the positive terminal or negative post????

nice job 👍

awesome bro

I’m having similar problems with my 16 Silverado. Thanks I’m gonna I got to check mine out from what I’ve learned here and there

Appreciate the video! I Have the same problem, chime is turned down and its loud. Bought new battery 3 months ago and now says low battery.. 2014 Ltz with the sound system package, could this be same issue? I’ll check it out for sure

Awesome job Oz, was this the one you did a little while ago when I asked about a 2014 Chevrolet that had a different issue or that you couldn't do a video on? It was on your last video before this like a couple weeks back. Good video buddy, I appreciate all your guy's help, knowledge and advice thru everything.

Good fix

Having the same issue with power draw, and the loud chime occasionally check for Amp draw and got nothing

I'm having that same problem,custom sounds hooked my amp ,10s, and lc71 , having a voltage problem and my chime is super loud with the chime volume all the way down, thanks Maan

2020 Chevy 2500hd diesel. Same problem. Can you please explain the process of holding up the volt meter inline to test?

Could my towing package be drawing power? It's in the same junction as this radio.

VERY IMPRESSED WITH YOUR USE OF DATA THAT LED TO EXCESSIVE DRAW

Always gotta be an aftermarket hack installer.....

goat ... mind just did this last night well not this but drained where are you located

Looks like work by Best Try.

I have a 2018 Silverado 1500. Had for 3 years. The dinger on my is really loud also. I cant stand that. I have it turned down all the way. What should I check? Thank You

That is to retain steering wheel controls and door dinger when installing a cheap aftermarket radio and or subwoofers. They come with a stupid loud speaker that most people duct tape foam over to quite it down. It's supposed to be on a key power obviously. Most likely previous owners had a android headunit and put most everything back to stock. Just easier to leave the thing behing the cluster and trade it in. Probably kept the radio for the 2017 2500hd they traded for.

Good video...

I do like the video

So did you tape off, leave off that wire?

How do these people sleep at night after jacking up someone’s ride like that? As you know once they mess up electrical systems they can brick a vehicle or leave someone stranded. Good video. Subbed. 👍

That was a hack job for sure. If you want to install an aftermarket amp, spend a couple of bucks more and get the proper patch cable that plugs into the factory harness. It's only about $30 and makes a clean install. If you want to ever remove it just unplug and everything goes back to factory. No more hacked up wiring.

My '07 does the same thing (did it last nite/this morning), but it does it so randomly, it would be a futile chase. Perhaps once a year.

14:26 that kind of "treasure" you never wish to find!

Check your third brake light for water leaks. Very common issue.

nice find! ugggh aftermarket crap strikes once again

Thanks for the informative troubleshooting video. Is the online website you used for the wiring diagram free?

Great job 👏 wish you could come to cali to help me with my 04 silverado my battery dies over night ..

Thanks for sharing with us those educational videos , do u know someone heavy trucks or bus technician youtube channel please. Thanks from Morocco

Oz...no links to other videos showed up in Video... need those,as iam currently dealing with issue....

My 2013, it was the onstar constantly running. After going through everything you can, i dislocated it under the drivers seat. Done.

What is the address to the Mitchell website?

Moral of the story: stop messing with factory wiring I ran into something similar with my 2014 Sierra…….someone messed things up. Leave it factory Leave things alone It works better that way

Why didnt you use other dmm to voltage drop on every fuse

With such a high draw, I wonder if an infrared camera would have saved a little time at the fuse box. Aftermarket installers should be required to supply a wiring diagram to help fix problems later. I suppose they don't want to do that with security systems.

WHAT was ALL that aftermarket stuff??

I have a 2007 Ford 250 and the battery goes dead in about 5 days I tested the battery and get 13v when charged the alternator is also putting out 14v . When i do the test to see draw the meeter goes to 1.39v and within 4 seconds goes to 0.19 and stays there . What could be wrong making the battery go dead in 5 days Thanks for any help Norm

I’m having a similar problem with the parasitic draw and I’ve unplugged every fuse I can, also replaced alternator and went through 4 batteries. It drains within 8-10 hours of shut off .Help! 07 Avalanche

👍👍

I'm having the same issue

👍

But still good video

Accessories should only be powered up with electrical system in run.

👍🏼👍🏼👍🏼👍🏼👍🏼

#1 🥇

Where are u located so I can take you my vehicle lol

Looks like it's been like this a while. Whoever did it though.. hhmm

Vatdafak 😂

Alternator

If you're skilled enough not to screw up that bad while wiring up aftermarket stereo crap, you'll never work a single second in a stereo shop because you'll make the owner worried that you're am undercover narcotics officer.

2022 are a pain

That’s all great and good but why not have the straw man to troubleshoot the symptom abd trace it to the cause-- not one trail -- upload docs or video the flow and let people screenshot their issue. Don’t worry - masonry is still using 109 year old methods. One trace is one of a hundred

Awesome fix.Oz This is EAGLE from Buddygo. We are a car product service company, we mainly produce the car Cabin Air Filter for cars. My purpose of contacting you is to seek business cooperation, and I look forward to your reply. best wishes

Some people just shouldn’t be allowed to install stereos.

good old after market BS

Oz , what part of Texas are you at ?
