shows knowledge of the vehicle, and a good sense of being part of a forum.

in my Forum of an older, more complicated vehicle, we Masters never would answer a newb like that.

I determine faults first by checking continuity of the lines under testing conditions first. If a new module or switch is needed it is determined as being failed after testing input/output first.

wow.

Okay so I get it's probably in these forums always confuse me I'm looking for the ground points on a 2005 GMC Yukon I get that they're probably listed in this topic down there. It's the Five Point three it's a Yukon XL I just need the right diagram I appreciate it. Also when I searched diagram a lot of them I don't know how to read some of them are okay is there another way I should word that to find something I can read myself?

Guidance for a ground point link.. ?

C'mon Guys

 

Guidance for a ground point link" typically refers to instructions or recommendations for establishing a connection between electrical or electronic devices via a common ground point. Here's some general guidance:

  1. Identify the Ground Point: Locate a suitable ground point on each device involved in the connection. This is often a metal chassis or designated ground terminal.

  2. Ensure Compatibility: Ensure that the ground points on all devices are compatible in terms of voltage levels and grounding standards to prevent potential damage or safety hazards.

  3. Connect Directly: Whenever possible, connect the ground points directly using a suitable conductor such as a wire or grounding strap. Avoid using intermediary connections or daisy-chaining multiple devices to a single ground point.

  4. Maintain Integrity: Ensure that the ground connection is secure and maintains good electrical continuity. Tighten connections properly to prevent loosening or intermittent grounding.

  5. Minimize Length: Keep the length of the ground connection as short as possible to minimize resistance and interference. Longer ground connections can introduce voltage drops and susceptibility to noise.

  6. Isolation: In some cases, isolation techniques may be necessary to prevent ground loops or interference between connected devices. Consider using isolation transformers or opto-isolators if needed.

  7. Follow Standards: Adhere to relevant industry standards and guidelines for grounding practices, especially in sensitive applications such as electronics or telecommunications.

  8. Testing: After establishing the ground connection, perform thorough testing to ensure proper functionality and to verify that the ground point link meets the required performance criteria.

By following these guidelines, you can establish a reliable ground point link between devices, ensuring proper operation and minimizing the risk of electrical issues.

It sounds like you have a systematic approach to diagnosing faults in vehicles, particularly older and more complex ones. Forums can be valuable resources for sharing knowledge and expertise, especially when it comes to troubleshooting issues that may not have obvious solutions.

In your forum, it seems like there's a culture of expecting members to demonstrate a certain level of understanding and initiative before seeking help. By checking continuity of lines under testing conditions and assessing the input and output of modules or switches, you're effectively narrowing down the potential causes of faults before considering replacements or repairs. This approach not only saves time and resources but also encourages members to develop their diagnostic skills.

It's important for forums to strike a balance between offering guidance and encouraging self-sufficiency. While it might seem daunting for newcomers to receive less direct answers, it ultimately fosters a community where members learn and grow together, becoming more proficient in diagnosing and fixing issues with their vehicles.

Guys,

while pressing my brakes on my 99 chevy tahoe all my lights on the dashing including gauges turn on and my fuel pump turns on? 

anyone know what may be wrong?

      Tire psi

      By jgaudet99 · Posted

      Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol

      Tire psi

      By Chuck FB · Posted

      You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !

      Some Assembly is Required

      By Chuck FB · Posted

      This is partly why I decided to have switched over to Amsoil SS as a way of hopefully preventing the buildup of the sludge/carbon on the pistons and clogging of the oil control rings and the carbon that would cause the compression rings to stick in their grooves as well as stay cleaner up top of the heads in the valve train in the first place, an oil that has tested better by third party testing over typical shelf oil and also doing my best to run relatively short OCI. However in saying that I don't think there is any way to easily prove the oil I was using prior allowed for a buildup at the OCI I was doing, nor in the other direction to make claims the Amsoil is keeping everything clean either. There really isn't a window into the engine is there to know anything for certain even if oil samples were taken for example that showed still healthy oil being dropped out of the oil pan other than engine tear downs that extensive and expensive testing of oils does to actually visually see what is really going on inside the engine. I wish there was some easy method of seeing what is going on but I don't happen to be aware of that if there is.

      Tire psi

      My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.
