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

[@andrewhigdon8346]

@@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? I’m serious though. Because I will only buy that vehicle next.

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.

[@AnthonyJ350]

Thank you!

[@andrewhigdon8346]

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 ?

This worked for a phantom problem with excessive low idle, not shifting / delayed shifts, burning smell during shift, cylinder misfire codes ect.

[@georgecurtis6463]

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.

[@AnthonyJ350]

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.

[@clydea.murphy2219]

I never heard the model T had catalytic convertors, them one wire o2 sensors sure are old school!! lol

[@albertcassler8763]

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

[@feeneysauto3432]

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

Hey Guys, so I live in Calgary Alberta......With this said, our winters get frigidly cold -20C common......my 4wd service comes on/fuse blows/lights on selector switch goes out. Nothing works...found a write up - not sure if its from GM directly. But it states, if your 20amp ATC fuse keeps blowing, but Encoder @ T-case works......front diff actuator works. You're getting get grounds.....good voltage at connectors....( Bench test front actuator ) and it works.......and there is no code for TCCM ( Transfer Case Control Module ) ....it is the 1640 connection - they used 18 gauge wire from factory but during colder than normal ambient temps - it will spike in amps and blow the fuse....The easy fix is replace with 25amp fuse. OR replace the Orange wire - with 16Awg. DONT GO SPLURGE ON PARTS BEFORE YOU DO ALL YOUR CHECKS!!!!

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.

do you have to disconnect the negative from the battery before doing anything else? or is it safe to remove, clean, and reconnect grounds with the battery connected?

To be 100% safe it's best to disconnect the battery, but if just adding grounds you can leave it connected.

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?

Ive inherited an 05 silverado ext. Cab with 75,000 driven like a car miles on it.It had a number of bizarre electrical issues that your ground wire upgrade improved dramatically .GM refuses to come clean on these shortcomings and if I had purchased this truck, it would have been a slam dunk lemon law re buy.The electrical problems ive uncovered that are responsible for interior fires that trapped people in the cab and burned them to death were determined to be from deteriorating grounding mostly due to substandard harness quality and materials.Several 3rd world suppliers have had their turn at making harness assemblies only to create trouble where there was none. I would love to hire Ron Francis to autopsy a few specific GM death cruizers for shits n giggles but it would do no good. sorry about the rant.but learning this stuff about chevy trucks and how it has been dealt with makes me physically ill.

[@AnthonyJ350]

It's probably related directly with the transfer case. I would repair it. You can extend it and ground it higher up on the frame to keep it out of the elements. Just make sure to use the same thickness or a little thicker wire.

[@crazeyspivey]

You should inform watchers that they SHOULD NOT put dielectric grease on the actual ground connection to metal, or on the bolt or threads. Dielectric grease will PREVENT a good flow of electrons, and thus you will get a poor ground. ONLY put the dielectric grease on the EXTERIOR of the new ground bolt and around the outside of the wire connection area to prevent corrosion. I learned this the hard way on another vehicle.

[@AnthonyJ350]

Depends on the grease, because it's suppose to displace. All manufactures state it doesn't impede the connection.

[@AnthonyJ350]

I did a video on the grease here kzbin.info/www/bejne/j5itg36iepyjj8ksi=o2ZmiL2VDEm04iD1 Did you document your findings by any chance?

[@crazeyspivey]

@@AnthonyJ350 Others agree with me on this. Give this a try: Remove your batter cables from the posts, then apply dielectric grease all over the posts and inside the cable terminals. Reconnect them, and try driving your vehicle for a week. You will soon get very poor electron flow, and your starter solenoid will be making the typical clac-clac-clac-clac noise when you try to start.......just isnt getting enough amps to allow the solenoid to energize the starter. Another example: apply the dielectric grease liberally all over a standard auto light bulb metal end, where the electrons flow to/from it. Apply to the bottom part and around the metal side of the bulb, and then insert bulb back into connection. You will find a voltage loss going to the bulb, the bulb will burn weaker, or might fail to come on.
