Now I got to find your video about the current sensor and how to run the wire through it because that is exactly what I have suspected my problem has been with my 2007 Yukon I put a aftermarket stereo and subs in it and have been having charging issues with it since and major major voltage drop
Its really a good thing to check that ground on the passenger rear of engine it causes alot of problems! That ground on the frame under the driver seat area should be cleaned up every few years. The Rubber covers on the side post battery terminals should be removed because these side post batteries like to leak acid and trap it in the rubber cover and corrode the terminals causing lots of problems. These are 3 of the most common problems. Also the fuse boxes like to corrode make sure u have the cover on
I check and don’t have that passenger side ground. Can’t see that thinner wire on the block nor where it’s supposed to split off the harness. Have about 40 dtcs related to harness like knock, camshaft and HO2S
Could I just clip that ground on the passenger back side and run it to a different part on the block? While leaving the o-ring and clipped wire on the the block still?
I always kinda wondered if I cleaned to bare metal shouldn't it rust. I guess that why you check the grounds from time to time 😲 Great video, helped my 94, gauges, cruise,wipers lol even brake lights! Crazy trucks

You can solder wires onto the ground wire of each taillight and nut and bolt it to the frame. Spray with Fluid Film on the grounding point of the frame afterwards.
Mark Shock if grounds are the only real issue then I’m gonna say that’s good to go. Especially considering that with fords for example have way more serious issues
@@markshock2254 every car has some electrical ground issues, unless they only operate under ideal conditions for electrical connection longevity. My issues on my Dodge Magnum began after driving on a 7 mile long dirt road deep into a National Forest. It was a remote recording I had to do as part of my job. Well the road is really fun with some “spirited” driving. Obviously I pushed it too hard because ever since then I’ve had a few intermittent stalling issues. I’m convinced all the “outside of the scope of its intended use” vibrations and shocks simply loosened several ground straps or the like in places I haven’t found yet. I have performed the clean and replace on every spot I can see, and curiously enough, there seems to beat least a temporary improvement every time. My point here is that the car still got driven on our Charleston, SC roads and definitely wasn’t babied at all. Yet I had not one serious electrical issue until over 160,000 miles. All of my accessories, window switches, door locks, HVAC, stereo, you name it, all works as it should. It’s not if you’ll have electrical issues, more like when, unless you drive on a pool table with desert dry air, use the vehicle regularly, and are the luckiest guy here. Every make and model suffers from reality. Mercedes, Ford, Subaru, Volvo, Chrysler, Volkswagen, Renault,you name it. What vehicle has given you the experience to declare other vehicles POS?

great video..i found 2 more grounds on my 01 sierra right below the gas tank fill on the frame rail..one goes to the abs module and one goes to the back of the gas tank fill cap i guess for static discharge.
I remember a ground broke off a person's truck I know and occasionally the ABS comes on like Broken Ground was not replaced yet I'm thinking now maybe that's abs it is towards the back
@@AnthonyJ350 hey do you think it's broken around with the 2001 Chevy truck seems like it wants to stall one put in reverse definitely idles down occasionally ABS or brake light comes on did have a broken ground that wasn't replaced yet not sure what these grounds are called to buy Direct Fit replacements
I had crazy gauges and have gone through every ground to no avail. I finally came across a video and I pulled the cluster and spliced the ecm ground and went right to the dash frame. So far, my gauges have been fine.
This is a great video of an often overlooked GMT-800 issue. Did the wirebrush and undercoat procedure on the grounds @ the cab mount so many times I've lost count.
So I’m also trying to sort out some odd electrical issues, but the engine has never been affected. I can’t think of anything else that HASN’T been affected. Since you dine the same procedure several times, I’m assuming you were convinced you knew the culprit after the second time you did it. By the third time, what was your thinking as far as being obviously very, very convinced you were on the right path to fixing it? I have a fair bit of knowledge about basic signal and current flow, as I’m a live sound engineer, and these things can greatly affect my job performance. Each time did you see where you could make an improvement over the previous attempt? You know how when you are trying to fix something, and you THINK you knew what was and thought you had fixed it, but then the symptom persists, you are distraught over the time spent not fixing the problem. But often problems highlight solutions. For example, even though it would appear that all of these ground straps seem to be redundant , they are not, and the impedance and current on some of them are dependent on at least one current sensor in the engine bay. “Improving” current flow post current sensor can send some systems into glitch mode. I honestly was just asking if you were finally successful. Were you? Anyone who is repeating a repair like that has got to have a good and tangible understanding how the system works. And that’s my point. Just the fact that you’re doing this so many times shows something else is wrong as well. What were your results ?
Great video! In case it helps someone-I learned to use anti seize to prevent corrosion on bolted electrical connectors on my boat. It doesn't easily wash out and it prevents corrosion of the connection.
Great video Recently got an 02 Suburban and am having starting problems. Turn the key to start and it just clicks once but won't turn over. Battery and alternator are good. Do you think Cleaning and protecting all the grounds will solve the issue before I replace the starter?
Will do, its been an issue for a while now, and as im in Australia, no one knows anything about them 🤣 its been sitting at my mechanics yard for 6 months, i took it back to my shop last week. (Fyi its an 03 silverado with the 5.3 and its 4x4). Im most interested in the earth strap you outlined behind the engine on the firewall. The errors im getting are cambus voltage too low, so im positive after watching your vid its earth related 😉
@@AnthonyJ350replacing the ground that you outlined behind the engine worked. I ran mine the same way you did, similar wire ect. I checked a before and after with the meter, got .4 of an ohm before, so defiantly had a problem there. (After .1 or so). This worked for a phantom problem with excessive low idle, not shifting / delayed shifts, burning smell during shift, cylinder misfire codes ect. My guess is if you drive like this it will damage the transmission, it seems to effect the solenoids shift time. Thanks again for a great video.
@@chenzitong1 Thank you so much for giving feedback regarding this video. I'm really happy to hear it helped solve a bunch of issues on the truck. Don't forget to subscribe :)

Great video, i can see how to some people asking for better angles, or for you to zoom out because they are having trouble finding the grounds is their only comment. Everybody should realize that even though it is GM some of these grounds wont be in the same exact location as this truck, due to the year make n model. This video does give you a very good starting point to look and is very helpful in saving you money. As for the ones pointing out what looks to be cracked on this truck in their comments. This video is about ground issues and maintenance. Thank you for posting the video, I will be checking all the grounds mentioned in this video on my 2010 Escalade awd 6.2L Luxury trim.
Loved the video. Im in the process of cleaning all the ground connections you listed in the video. I see that the small wire on the back of my engine block is covered in dry oil/dirt. Im going to move it to a different location, hopefully it helps. What gauge wire did you use for the small wire? Thanks again for the video
@@AnthonyJ350 after cleaning all the grounds and moving the location of the ecm ground my yukon still had no power. I removed the plastic battery terminal covers and the issue has not happened again. I believe this fix is needed because the ground wires were very dirty. I would also add removing the plastic terminal covers to ensure there is a good connection with the battery.
Dielectric, sometimes referred to as tune-up grease, is a viscous " non-conductive" waterproof substance used to protect electrical connections ... Use a conductive contact grease at the contact points then one can apply a non-conductive die-electric grease over the point after its been installed.
The ground point under the dash...Is it on the driver's side or the passenger's side? The video has me confused, for the radio antenna is usually on the passenger side of the vehicle. It's as if that part of the video is flipped.
Yes, in most cases the electrical components will utilize a ground running from another source, causing an extreme load on that ground wire. You can tell by the discoloration of the ground wires carrying too much load. So find the faulty ground source and replace those burnt wires....burnt wires have more resistance than normal...police cars have extra grounds on the exhaust system to calm the negative eruptions during the combustion processes of ionization and yes I'm a smart ass
Been having problems with the speedometer gauge, it’s works most of the time but sometimes rarely it will not work at all I heard it might have to do something with one of the ground placements
@@carloschataing5030 I noticed my battery was a little weak, I changed it out and the problem has went away. It would mainly only have problems in the cold weather when it did have problems.
there are worse places in winter than the salt/sand mix the county uses in Mi. Found this out after moving to Montana and ran through a winter with magnesium chloride being used on the roads. Have to beat rotors off the hubs after one season
Thank you, thank you, thank you! I’ve had issues with my 07 Avalanche, it wouldn’t shut off when the key was turned off, and it was draining the battery. It’s not the same as the GMT800, but you definitely pointed me in the right direction to finding a corroded ground coming straight from the battery. Amazing video!!!
@@4g63a1 so repairing the ground fixed a lot of my issues, but I still had battery drain. We ended up replacing the fuse box and have had no issues since.
@@anandsihra I have an 07 silverado with 5.3. Having same issues for months including taking the key out and it stays running. Did the ground fix that?
Hopefully you get this message within your video you were pointing out the ground wire into the right of your hand it appears the frame on that truck is cracked
@@AnthonyJ350 perfect Thank you!! I noticed you mentioned a amperage sensor over by battery do you have a better picture as I can find mine 03 Chev Silverado 2500hd 6.0litre gas
Couldnt you just route the negative battery cable through the sensor and to a distribution block and then run additional grounds to that block as well?
To be fair, a lot of these ground placements are common on all pickups. I've found grounds on Japanese SUVS behind the front bumper shell. At least these you can get to, clean and grease.
You also have to make sure if you're adding grounds to the battery it passes through the sensor for the regulated voltage control system ruclips.net/video/OqylgRKiC-A/видео.html
Just to throw this out there, dielectric grease is actually an insulator and can not conduct electricity. It is pretty good at keeping them from corroding, but, putting it between a ground terminal and a physical ground is a good way to keep that ground from working.
Did you test and verify that theory? Because I did here: ruclips.net/video/YgJRKlE7pYg/видео.html Have you had connections fail due to dielectric grease consistently?
Long ago, Mercedes had issues with o2 sensors having issues. Well, the fix was to add a ground from the o2 sensor body to the frame. Rust, etc at the exhaust connections was not giving good ground pathway. These were the first type sensors without their own int ground in case that confuses you young ones.
But the PCM gets its ground from the vehicle and isn't it better to have a vehicle with less potential ground loops? Can you also explain why some Toyotas like an FJ Cruiser and 90's Hondas ground the valve cover? Grounding the casings must help at least for the charging system since the ground for the alternator is the back of the casing.
I'm glad I found you! Okay so I own a 2500HD chevy and the electrical system is not correct. My FASS pump fluctuates in noise, when my blinker is on, the AC fluctuates, when I'm driving on cruise control, putting the window up stops it.. and there's more :( any ideas? Plz and thank you.
Check all the grounds and plugs. Drop the spare and Check, clean and dielectric grease all the plugs you can find along the frame and in the middle of it.
I had to disconnect the ground on the driver side frame and sanded off all the old fram coating to bare metal then reconnect the ground wire and repainted and my problem was was fixed
@@AnthonyJ350 so I am building an rcsb it’s an 01 but fully coverted to an 07 classic but it was all apart when I got it and I connected everything and it wouldn’t crank stumbled upon your video wich was a life saver and medicine for this headache thank you 💯
I have 2001 Silverado with led taillights that was blinking everywhere and I couldn’t figure out the problem. Until I changed out the taillights to original ones, that I saw that the bulbs were dim. My fix was the ground under the driver side pillar. Thanks a lot.
Do you think its a ground problem when i use the window switched the lights dim out and the cluster as well. Not only that when i turn the ac on the rpms drop and go up, also another thing is that when reversing and turning the wheel the truck sometimes turns off. Im beggining tk think its an electrical problem. Any idea or tips of what ir could be ?
At 1:00 , I have a question if anyone knows… I checked on my 2000 Silverado and mine doesn’t have a ground wire there, weird thing is the thread inside looks shiny which means someone or previous owner took out the ground? Usually I would of seen a dangling wire (ground) swinging around but I don’t see it anywhere or know where it’s suppose to go.
It’s funny when I was looking to fix a multiple mis fire in my 2015 Silverado I came across this video, after I fix the multiple misfire problem, the P0430 catalyst converter sensor come up and now 15 other sensors came up all related to low voltage and faulty ground. I only have 39,500 on my 2015 Silverado but man seriously, if you don’t have one, don’t buy one and if you have one and don’t have any issues yet, sell it and get a Toyota Tundra or Tacoma while you can, I really like my truck but the 2014-2018 are very poorly engineered, this model of trucks are probably the worst trucks Chevrolet ever build, if you are willing to put some work and some money they may be a good truck but the list of problems is long and getting longer: Lifters problems, Injectors problems, Faulty ground wires, Fuel pump problems, Oil pressure switch issues and the list keeps going. Good luck to all of you Chevy owners
One time we could find the main Body harness for the dashboard main harness ground so I soldered a wire to the main harness ground and grounded it problem fixed
I think it aids with radio reception. I worked on a truck and repaired it and the AM reception got much better. I would just fix it, it's there for a reason.
Just found this after watch tons of videos. Yours by far was the best to explain it! I have a 2012 Chevy Express 2500 and started having issues. Went and looked at the ground strap and mine is worse than that one!! It will be changed today!!! Hoping it fixes my issues.
@@AnthonyJ350 problem SOLVED!!!! Heads up for anyone that the bolt to PS pump and also to the motor mount is 15mm. You’ll need an open box end wrench and a 15mm socket (goes quicker). Van fired right up!!!
@@AnthonyJ350 it was the ground strap that’s attached to the battery ground cable (factory). It was rotten off and I gave it a little tug and it fell off. It was attached to the block (with battery wire crimped together) and then bonded to the frame. I got another strap (not the best) and grounded it to the power steering pump bolt and then to the motor mount bolt attached to the frame, turned the key and it fired right up.
Thank you! Very similar, the frames are practically the same. Different in the rear because the rear suspension of the SUV is different than the pickup truck.
@@jorgeperezdeprado8941 Upgrade the grounds, and a high quality battery helps too. Upgrade frame to body ground straps, motor to frame and frame to battery.
@@AnthonyJ350 So far I have not driven the truck yet. I only ran it idle for a few minutes afterward and just checked the voltage gauge which indicated perfect at ~14 Volts. The two grounds located under the dr. side B pillar were very rusted, so I'm sure the effort was worth it for that reason alone. One reason I wanted to clean all the chassis grounds was due a lot of different intermittent, weird, random electronic activity like the heated seats activating and cycling on their own, cruise control dropping out, all of the 4WD indicator lights illuminating all at once, etc. like the truck is possessed, hahaa. Maybe cleaning the grounds will help.
My ground wire broke off the back of the engine block so I ran it to the firewall. Still had "reduced engine power" intermittently so I replaced the throttle body and viola it's finally fixed. 2003 Yukon
Glad to hear you figured out the fix. If you get the reduced power message I believe you should change oil as soon as possible because the engine runs rich you protect itself. The details are in the owner's manual so you should review that.
My 6.0 vortec dies while breaking also my voltages hand drop when I cut on my fan for heat and AC. I put in new battery and upgraded alternator spark plugs and wires. I haven't checked the small wire yet. Help me please!
@@AnthonyJ350 my point is the original was mounted on a block point should the additional one be mounted on the block too or since it is a ground it does not matter? I ask myself why would Chevy put these ground points in such difficult places in the first place. Would relocating them to the front part of the engine be any different in function from where they are? I am guessing not. Thanks
@@condor5635 I didn't want to move it from there because of it may need to be there as a reference point. You probably could ground it to another place and it would be fine, I chose not to.
I am currently having an issue where my truck will initially rev out but as soon as the rpm settle to idle it will only rev out to about 2500 rpm. I have replaced every part in the throttle control system. I have not messed with the grounds tho. Found out the voltage on tps 2 wire is unsteady after professional diagnostic. Still have yet to fix
you have to be carefull with grounds now a days. many newer vehicles use a amp sensor over the negative battery cable. if you add grounds, it with screw with your charging system... there are tsb's for this.
What’s up man I have a 2007 Chevy suburban I’ve added a k&n intake led headlights and a sound system (subwoofer ) 15” powers from 1200-2200 rms. The problem is that sometimes it works fine and all but when u turn on the bass or some times randomly it does is that it if u r driving it the a bunch of codes start to pop up the gage does not read anything like the rpms speed limit … the windows don’t work. What does work is the lights engine, seats to recline up and down and sunroof window. If u turn it off it will not want to start again and might have to take a while or a lot of cranks to start it. The other thing is that it know has a new battery and a new starter all fuses read good (inside and outside) and the alternator works good. What els could it be wrong?
That's a lot of power. Did you upgrade the grounds and the positive wire from the battery to the alternator? Also you'll want to use a high quality battery like a North Star or even install a secondary battery.
Would a bad ground cause weird electrical issues such as wipers coming on by themselves, lights turning on when key isn't even in ignition and blinkers coming on?
Do NOT chain ANY additional grounds to the PCM ground unless that chain ground has the same source and end point. It is VITAL the pcm ground not have any other ground paths crossing over it
I did, and my truck has almost 300,000KM and I did another truck that has over 900,000KM. On top of that I'll install remote starter/ security systems in and ingrate further with the CANBUS system with head units that give vehicle information ruclips.net/video/hAKb84r9et0/видео.html
They put every other electrical component in a case. Is it really too much to ask to have one large gauge wire that runs to a part of the frame that experiences less weather with a large bolt that way you only have to service and check one bolt. Then that wire can go central grounding terminal housed in a weather resistant service box, where all the grounds go and are labeled. With 5 or 6 additional ground terminals for custom wiring? Nah let’s just place them all over the frame where most of the salt and snow hit.
I have a 2006 Silverado 1500 5.3 recently my truck would turn off when in gear and it loses power and all lights flicker and dim I changed spark plugs, wires and ignition coils and have the same problem could it be a ground wire?
I would look at all main battery connections and connections at the power distribution box under the hood. Remove the plastic surround and make sure the main battery cables are tight under there as well.
The ground behind the A pillar that's "known for failing" how would I confirm if mine is bad and what would be the fix? I've been having several electrical issues and I've got 5 different codes for "low voltage" and "open circuits" and every single one of the units experiencing these issues is grounded at this location. It looks fine to me. Tight connection etc. But I don't know how to confirm if it's an issue or not.

Thanks, I’ve got instrument cluster issues on a 01 Silverado. I’ll give this a try.
Let us know. The cluster stepper motors might be worn out.
I had crazy gauges and have gone through every ground to no avail. I finally came across a video and I pulled the cluster and spliced the ecm ground and went right to the dash frame. So far, my gauges have been fine.
This is a great video of an often overlooked GMT-800 issue. Did the wirebrush and undercoat procedure on the grounds @ the cab mount so many times I've lost count.
Thank you!
So I’m also trying to sort out some odd electrical issues, but the engine has never been affected. I can’t think of anything else that HASN’T been affected. Since you dine the same procedure several times, I’m assuming you were convinced you knew the culprit after the second time you did it. By the third time, what was your thinking as far as being obviously very, very convinced you were on the right path to fixing it? I have a fair bit of knowledge about basic signal and current flow, as I’m a live sound engineer, and these things can greatly affect my job performance. Each time did you see where you could make an improvement over the previous attempt? You know how when you are trying to fix something, and you THINK you knew what was and thought you had fixed it, but then the symptom persists, you are distraught over the time spent not fixing the problem. But often problems highlight solutions. For example, even though it would appear that all of these ground straps seem to be redundant , they are not, and the impedance and current on some of them are dependent on at least one current sensor in the engine bay. “Improving” current flow post current sensor can send some systems into glitch mode. I honestly was just asking if you were finally successful. Were you? Anyone who is repeating a repair like that has got to have a good and tangible understanding how the system works. And that’s my point. Just the fact that you’re doing this so many times shows something else is wrong as well. What were your results ?

Great video! In case it helps someone-I learned to use anti seize to prevent corrosion on bolted electrical connectors on my boat. It doesn't easily wash out and it prevents corrosion of the connection.
Thanks for sharing!
Good idea I never thought about. It's not easy to remove off of your fingers don't wear gloves
Careful! Make sure you check the conductivity of the type of anti-seize you will be applying!

Great video
Recently got an 02 Suburban and am having starting problems. Turn the key to start and it just clicks once but won't turn over. Battery and alternator are good.
Do you think Cleaning and protecting all the grounds will solve the issue before I replace the starter?
I would definitely clean and upgrade the grounds. But sounds like the starter solenoid isn't happy.
Your a champion. My chev runs occasionally, dosnt shift ect. Defiantly going though all the grounds you mentioned 🤙
Let us know if doing this helped. The more people that give feedback helps others.
Will do, its been an issue for a while now, and as im in Australia, no one knows anything about them 🤣 its been sitting at my mechanics yard for 6 months, i took it back to my shop last week. (Fyi its an 03 silverado with the 5.3 and its 4x4). Im most interested in the earth strap you outlined behind the engine on the firewall. The errors im getting are cambus voltage too low, so im positive after watching your vid its earth related 😉
@@AnthonyJ350replacing the ground that you outlined behind the engine worked. I ran mine the same way you did, similar wire ect. I checked a before and after with the meter, got .4 of an ohm before, so defiantly had a problem there. (After .1 or so).
This worked for a phantom problem with excessive low idle, not shifting / delayed shifts, burning smell during shift, cylinder misfire codes ect. My guess is if you drive like this it will damage the transmission, it seems to effect the solenoids shift time. Thanks again for a great video.
@@chenzitong1 Thank you so much for giving feedback regarding this video. I'm really happy to hear it helped solve a bunch of issues on the truck. Don't forget to subscribe :)
Yep I'd say the wire behind the motor on my truck will probably be my fix for it thanks guys I'm ganna try an see if I can get my truck fixed an hopefuly it works out it wood run rely good clear the engine lite off thin like wen its hot it will lose power an not shift out sometimes not even want to go over 30mph I cud stop an Trun the truck off an it woodent fix it till the next day wen it wood be colder on it but this wormer wether has rely got it messing it up everything that can have a code for it it gets them all popping up now

Great video, i can see how to some people asking for better angles, or for you to zoom out because they are having trouble finding the grounds is their only comment. Everybody should realize that even though it is GM some of these grounds wont be in the same exact location as this truck, due to the year make n model. This video does give you a very good starting point to look and is very helpful in saving you money. As for the ones pointing out what looks to be cracked on this truck in their comments.

Hey Anthony
Thank you for your help man i did everything you showed on this video
You are a great teacher
thanks
So glad the video helped you!
Love your video please make another updated one soon if you still have the truck I want to go over every ground and see the location.
Yup, I still have the truck
Nice help thanks 🙏
Glad to hear it helped!
Loved the video. Im in the process of cleaning all the ground connections you listed in the video. I see that the small wire on the back of my engine block is covered in dry oil/dirt. Im going to move it to a different location, hopefully it helps. What gauge wire did you use for the small wire? Thanks again for the video
I used 16 gauge. Thanks for watching! Let us know how it worked for you.
@@AnthonyJ350 after cleaning all the grounds and moving the location of the ecm ground my yukon still had no power. I removed the plastic battery terminal covers and the issue has not happened again. I believe this fix is needed because the ground wires were very dirty. I would also add removing the plastic terminal covers to ensure there is a good connection with the battery.
@@f_beezy9285 Thanks for sharing!
Mines don't have a wire on back engine block ,so what the plan after that?
Dielectric, sometimes referred to as tune-up grease, is a viscous " non-conductive" waterproof substance used to protect electrical connections ...
Use a conductive contact grease at the contact points then one can apply a non-conductive die-electric grease over the point after its been installed.
Thanks for the comment!
Yes thank you...... many people really don't have a clue about dielectric!!
Wow just youtubed this...I was using it all wrong! Thanks for the comment.
No-oxide
Thanks for your help
Glad the video helped you!
You can never have enough ground.
Completely agree!
The ground point under the dash...Is it on the driver's side or the passenger's side?
The video has me confused, for the radio antenna is usually on the passenger side of the vehicle. It's as if that part of the video is flipped.
Check the driver's side. Always check both sides though.
do you unhook the batterie/s before you detach all the ground wire?
Doesn't hurt to
Thanks !!
You're welcome!
What’s the point of showing the ground if you aren’t saying where on the car you’re looking
It's the only wire going to metal on the screen.
Yes, in most cases the electrical components will utilize a ground running from another source, causing an extreme load on that ground wire. You can tell by the discoloration of the ground wires carrying too much load. So find the faulty ground source and replace those burnt wires....burnt wires have more resistance than normal...police cars have extra grounds on the exhaust system to calm the negative eruptions during the combustion processes of ionization and yes I'm a smart ass
Thanks for sharing!
Thanks for the video. What model truck is in this video? My 01 gmc sierra 1500 doesn't have those ground wires under the a- pillar.
You're welcome and thanks for watching! It's a 2005 half ton shown in the video. 2003 wiring changed and 2005 it changed even more for the GMT-800.
Been having problems with the speedometer gauge, it’s works most of the time but sometimes rarely it will not work at all I heard it might have to do something with one of the ground placements
Could also be the stepper motor of the gauge.
Did you solve it?
@@carloschataing5030 I noticed my battery was a little weak, I changed it out and the problem has went away. It would mainly only have problems in the cold weather when it did have problems.
Got a 2001 Silverado rusted all to hell. Never touched the grounds, never had a problem in Michigan salt
I feel you on the Michigan rust. I wish I was fortunate enough to not have had ground issues though.
Use Fluid Film on the undercarriage to keep rust at bay.
there are worse places in winter than the salt/sand mix the county uses in Mi. Found this out after moving to Montana and ran through a winter with magnesium chloride being used on the roads. Have to beat rotors off the hubs after one season

Thank you, thank you, thank you! I’ve had issues with my 07 Avalanche, it wouldn’t shut off when the key was turned off, and it was draining the battery. It’s not the same as the GMT800, but you definitely pointed me in the right direction to finding a corroded ground coming straight from the battery. Amazing video!!!
Glad to hear the video was able to help you!
a blown voltage regulator can also cause drain back when key is off
do you have a better source to resolve your issue i have an 07 avalanche and am having the same problems
@@4g63a1 so repairing the ground fixed a lot of my issues, but I still had battery drain. We ended up replacing the fuse box and have had no issues since.
@@anandsihra I have an 07 silverado with 5.3. Having same issues for months including taking the key out and it stays running. Did the ground fix that?
Hopefully you get this message within your video you were pointing out the ground wire into the right of your hand it appears the frame on that truck is cracked
Nope that's just undercoating.
Does it matter the gauge wire? I have big battery cable lines to ground with... They will never break
Thicker is always better when it comes to grounds. It'll be more durable and flow more amperage.

Couldnt you just route the negative battery cable through the sensor and to a distribution block and then run additional grounds to that block as well?
You could. Just make the new ground thicker.

@@JDV10M5 Thank you for doing that!
It would be cool if gm would fix this issue that is exactly the same on every Chevy back to at least 92
To be fair, a lot of these ground placements are common on all pickups. I've found grounds on Japanese SUVS behind the front bumper shell. At least these you can get to, clean and grease.
I always feel free to add my own grounds, in fact, when I run it right to the NEG terminal I call it a dedicated neutral
Nice, sounds like you come from an AC voltage background. There's no neutral in a DC system.
You also have to make sure if you're adding grounds to the battery it passes through the sensor for the regulated voltage control system
ruclips.net/video/OqylgRKiC-A/видео.html
Just to throw this out there, dielectric grease is actually an insulator and can not conduct electricity. It is pretty good at keeping them from corroding, but, putting it between a ground terminal and a physical ground is a good way to keep that ground from working.
Did you test and verify that theory? Because I did here: ruclips.net/video/YgJRKlE7pYg/видео.html
Have you had connections fail due to dielectric grease consistently?
Long ago, Mercedes had issues with o2 sensors having issues. Well, the fix was to add a ground from the o2 sensor body to the frame. Rust, etc at the exhaust connections was not giving good ground pathway. These were the first type sensors without their own int ground in case that confuses you young ones.
But the PCM gets its ground from the vehicle and isn't it better to have a vehicle with less potential ground loops? Can you also explain why some Toyotas like an FJ Cruiser and 90's Hondas ground the valve cover?
Grounding the casings must help at least for the charging system since the ground for the alternator is the back of the casing.
I never heard the model T had catalytic convertors, them one wire o2 sensors sure are old school!! lol
I'm glad I found you! Okay so I own a 2500HD chevy and the electrical system is not correct. My FASS pump fluctuates in noise, when my blinker is on, the AC fluctuates, when I'm driving on cruise control, putting the window up stops it.. and there's more :( any ideas? Plz and thank you.
Check all the grounds and plugs. Drop the spare and Check, clean and dielectric grease all the plugs you can find along the frame and in the middle of it.
I had to disconnect the ground on the driver side frame and sanded off all the old fram coating to bare metal then reconnect the ground wire and repainted and my problem was was fixed

Do you think its a ground problem when i use the window switched the lights dim out and the cluster as well. Not only that when i turn the ac on the rpms drop and go up, also another thing is that when reversing and turning the wheel the truck sometimes turns off. Im beggining tk think its an electrical problem. Any idea or tips of what ir could be ?
Poor grounds and possibly old battery. A little dimming when those accorries run is normal, especially on power windows.

At 1:00 , I have a question if anyone knows… I checked on my 2000 Silverado and mine doesn’t have a ground wire there, weird thing is the thread inside looks shiny which means someone or previous owner took out the ground? Usually I would of seen a dangling wire (ground) swinging around but I don’t see it anywhere or know where it’s suppose to go.
Do you see the wires tucked up anywhere?
How about the cracked frame does that help bad grounds?
What are you talking about?
Never seen a frame that cracked before. Suppose he doesn't even see it?
@@ronevrerett5670 It's not a cracked frame. It's paint chipping away or undercoating
Nope it wouldn't. That's just cracking in the undercoating.
It’s funny when I was looking to fix a multiple mis fire in my 2015 Silverado I came across this video, after I fix the multiple misfire problem, the P0430 catalyst converter sensor come up and now 15 other sensors came up all related to low voltage and faulty ground. I only have 39,500 on my 2015 Silverado but man seriously, if you don’t have one, don’t buy one and if you have one and don’t have any issues yet, sell it and get a Toyota Tundra or Tacoma while you can, I really like my truck but the 2014-2018 are very poorly engineered, this model of trucks are probably the worst trucks Chevrolet ever build, if you are willing to put some work and some money they may be a good truck but the list of problems is long and getting longer:
Lifters problems, Injectors problems, Faulty ground wires, Fuel pump problems, Oil pressure switch issues and the list keeps going.
Good luck to all of you Chevy owners

Is the ground going from the engine bay body to the hood on the drivers side super important? Mine was broken when i got the truck 3 years ago.
I think it aids with radio reception. I worked on a truck and repaired it and the AM reception got much better. I would just fix it, it's there for a reason.
Mines been broken for years. Only thing that doesn’t work with the hood to firewall ground wire broken is the underhood light which I don’t use.
Factories always run the bare minimum of size wires. Upgrade all wires ,would help the whole vehicle.
Upgrading the wiring definitely will help everything.
Just found this after watch tons of videos. Yours by far was the best to explain it! I have a 2012 Chevy Express 2500 and started having issues. Went and looked at the ground strap and mine is worse than that one!! It will be changed today!!! Hoping it fixes my issues.

Thanks for this video! I was able to locate and clean up all of the chassis ground connections on my '04 Yukon.
Nice! Did you notice a difference with anything afterwards?
@@AnthonyJ350 So far I have not driven the truck yet. I only ran it idle for a few minutes afterward and just checked the voltage gauge which indicated perfect at ~14 Volts. The two grounds located under the dr. side B pillar were very rusted, so I'm sure the effort was worth it for that reason alone. One reason I wanted to clean all the chassis grounds was due a lot of different intermittent, weird, random electronic activity like the heated seats activating and cycling on their own, cruise control dropping out, all of the 4WD indicator lights illuminating all at once, etc. like the truck is possessed, hahaa. Maybe cleaning the grounds will help.
@@CtotheDitti Did you put some dielectric grease in between the connections as well.
@@AnthonyJ350 Absolutely, yes. And I smeared more all around the exteriors of each connection too.
Is it possible a bad grand couse a electrical smell
Very possible. A poor ground may cause an electronic to pull more amperage because the voltage is low.
Hi I Wish You Was In Boynton Beach Florida I Can Pay You Fix It
I'm sure there's a bunch a decent car audio shops in your area that can do the job easily if you show them the video.
My ground wire broke off the back of the engine block so I ran it to the firewall. Still had "reduced engine power" intermittently so I replaced the throttle body and viola it's finally fixed. 2003 Yukon
Glad to hear you figured out the fix. If you get the reduced power message I believe you should change oil as soon as possible because the engine runs rich you protect itself. The details are in the owner's manual so you should review that.
Clean nice work👍
Thank you!

Thanks for watching!
Wouldn’t it have been a better idea to run that additional ground to the block again somewhere else more accessible instead of the firewall?
It was easy enough for me to get at.
@@AnthonyJ350 my point is the original was mounted on a block point should the additional one be mounted on the block too or since it is a ground it does not matter? I ask myself why would Chevy put these ground points in such difficult places in the first place. Would relocating them to the front part of the engine be any different in function from where they are? I am guessing not. Thanks
@@condor5635 I didn't want to move it from there because of it may need to be there as a reference point. You probably could ground it to another place and it would be fine, I chose not to.

No I just add them on
I am currently having an issue where my truck will initially rev out but as soon as the rpm settle to idle it will only rev out to about 2500 rpm. I have replaced every part in the throttle control system. I have not messed with the grounds tho. Found out the voltage on tps 2 wire is unsteady after professional diagnostic. Still have yet to fix

What’s up man I have a 2007 Chevy suburban I’ve added a k&n intake led headlights and a sound system (subwoofer ) 15” powers from 1200-2200 rms. The problem is that sometimes it works fine and all but when u turn on the bass or some times randomly it does is that it if u r driving it the a bunch of codes start to pop up the gage does not read anything like the rpms speed limit … the windows don’t work. What does work is the lights engine, seats to recline up and down and sunroof window. If u turn it off it will not want to start again and might have to take a while or a lot of cranks to start it. The other thing is that it know has a new battery and a new starter all fuses read good (inside and outside) and the alternator works good. What els could it be wrong?
That's a lot of power. Did you upgrade the grounds and the positive wire from the battery to the alternator? Also you'll want to use a high quality battery like a North Star or even install a secondary battery.
Can you please comment on fire wall to hood ground. It’s purpose etc. Thank you
Eliminate static electricity or help aid in AM reception as the whole vehicle acts like an antenna to help that radio band. That's all I can think of.
Rust prevention
silicone tape is better to wrap wires with
Like a whole harness? I haven't seen it widely used in car audio, first responder or race car applications though.
I really like the way each ground is sectioned and then you label the area on the video. seriously ease to follow. thank you.
Glad you found this video helpful 🙂
Would a bad ground cause weird electrical issues such as wipers coming on by themselves, lights turning on when key isn't even in ignition and blinkers coming on?
Possibly or a bad turn signal switch.
Bullbutter
Do NOT chain ANY additional grounds to the PCM ground unless that chain ground has the same source and end point.
It is VITAL the pcm ground not have any other ground paths crossing over it
I did, and my truck has almost 300,000KM and I did another truck that has over 900,000KM. On top of that I'll install remote starter/ security systems in and ingrate further with the CANBUS system with head units that give vehicle information ruclips.net/video/hAKb84r9et0/видео.html

How did you find the ground wire on the back of the engine ? How did you know which one it was
It's the only ground wire back there.
@@AnthonyJ350 i actually found it It was 2 wires in the same location black white stripe and it was an issue

Can we see the electrical work you do?
They put every other electrical component in a case. Is it really too much to ask to have one large gauge wire that runs to a part of the frame that experiences less weather with a large bolt that way you only have to service and check one bolt.
Then that wire can go central grounding terminal housed in a weather resistant service box, where all the grounds go and are labeled. With 5 or 6 additional ground terminals for custom wiring?
Nah let’s just place them all over the frame where most of the salt and snow hit.
That's engineers for you.
I have a 2006 Silverado 1500 5.3 recently my truck would turn off when in gear and it loses power and all lights flicker and dim I changed spark plugs, wires and ignition coils and have the same problem could it be a ground wire?
I would look at all main battery connections and connections at the power distribution box under the hood. Remove the plastic surround and make sure the main battery cables are tight under there as well.
The ground behind the A pillar that's "known for failing" how would I confirm if mine is bad and what would be the fix? I've been having several electrical issues and I've got 5 different codes for "low voltage" and "open circuits" and every single one of the units experiencing these issues is grounded at this location. It looks fine to me. Tight connection etc. But I don't know how to confirm if it's an issue or not.
You would have to measure resistance to the devices they're connected to, at the device.
