Wiring Diagrams Explained - Easy Peazy 

This Guy is A Trump Man..M.A.G.A. He is Making American Great Again

@@midnightrunner684 Underrated? He has almost 1 million subscribers.

@@midnightrunner684 naa he made it clear in a video he doesnt like trump and his fanboys punks

Yea politics aside, he is a smart person on cars but morals, he needs to learn from real data, not fake. But awesome content. Usually by the time someone makes good money 40 50 years, they turn right from left. Usually...the left lets u live a life of anything goes without a one true creator and savior god, jesus and holy spirit. The right side usually has better moral standards, long life span, less depression, more true joy...it goes without saying really, but u have to know the knowledge first. Think for yourself

I agree and im tired to be the guy praying for the problem to be small all the time. Not even a pro but im ready to get it or die trying

Me too. Have you viewed any other electrical related videos frok him. I only see the mechanical stuff. Also i browsed on his patreon page but could not pick a membership

Especially if jobbers have been in their or any work has been done by a garage uninterested in following the schematic and colour scheme

Hi Patrick thank you for your support both here and on my patreon page :) Long ratcheting wrenches are truly a life saver, especially if you've got your hands full with 20 plus cars :) cheers

@@myRatchets hey I have a Corvette c6 l looking for a Corvette c6 wiring harness can you help

Glad you liked it

Try AlldataDIY. $30.00/year for 1 vehicle ( half that for subsequent vehicles). Includes component location info. Crucial for electrical diagnosis. If you're looking at wiring diagrams, you'll almost always need to know where the specific connectors, splices and grounds are physically located in the vehicle. This subscription also includes all factory procedures such as component testing and replacement procedures, torque values and a lot of other info. Worth every penny.

You never know what resources you could find at the public library and if they don't have it you can request them to get it you never know

Go to ebay and find a service manual pdf. Like 15-30 bucks has everything you'll need

@@mauricioespinoza5390 If you're referring to manuals such as Hayne's and Chiltons, they only have a small selection of wiring diagrams for a given vehicle. For example, the Haynes manual I have for one of my cars has 11 pages of wiring diagrams. In reality, there can easily be 50-100 pages or more of wiring diagrams for a given car. They even state that "since they can't include all wiring diagrams for the car, they've just included the most commonly used ones".

@@davidquinn6161 No, I mean actual dealership service manuals with all the wiring diagrams. I got one for a 1997 camry had all the service instructions.

You have to recreate the environment that the sensor is sensing in order to see if it's working or not. If it's a temperature sensor, then changing the temperature (boiling/freezing water) and watching for a change in the resistance on the sensor can be helpful. Sometimes you just have to back-probe the wires going to the sensor to see whether it's in the proper operating range. (often changing - sometimes too quickly for the voltmeter to follow accurately). Sometimes you have to just disconnect something and see if the car's behavior changes. If it doesn't that's not always a good thing. Sometimes you have to "activate" that circuit in order to test with pulling a connection. For instance, a high speed fan circuit may require a certain temperature range, or RPM or the activation of the air conditioning compressor. Bottom line, understand how the sensor works, so you can see how to test it. Intermittent electrical problems are the ones that you pull your hair out on... Learn to also use a OBD2 scanner that shows higher details than just reading codes. Some are phone based. Get a decent volt meter and know how to use it to test across loads, or check amperage readings (need to swap probe positions for this). Learn not to do resistance checks on a live circuit. Learn ohms law. That way you can use a voltmeter to look at voltage drops across a load and determine current readings. Learn to "divide and conquer" It may mean you have a single sensor or problem causing multiple problems. But you may also learn that there are multiple problems there, and the computer has been compensating for it. Also think about what might have caused a sensor to fail (ie, O2 sensor can get clogged when running too rich for too long, or burning odd substances, or NOT burning fuel until too late (in the catalytic converter - makes loud booms).

all manufactures have tech info websites that you can pay like $20 for one days access, and look through as many wiring diagrams as you want. You used to be able to download the info. as well but they dont allow that anymore. But you can print or screenshot the entire manual if you wish.

@@Mach141 Yeah, I tried that once. Granted it was a few years ago and I don't remember the name of the website, but it was highly recommended by everyone I talked to. I paid my 20 or 30 bucks for 3 or 4 days of access to a "complete" wiring diagram. I don't recall which vehicle (it wasn't my Tacoma so it had to be a US vehicle) or which system I was working on. Anyhow, the website explicitly stated that it covered that system on that year of vehicle. On the diagram it clearly showed a wire going to that system... and that was it. No further details. I carefully examined all 70 or 80 pages of diagrams. Nothing. Half a week and at least $20 wasted. Before I cough up money again, I want some assurance that the information I need will be there or at least some kind of refund.
