Fast-Track Diagnostics: Mastering Go/No-Go Techniques to Save Time and Earn More

Welcome to our detailed tutorial where we introduce and demonstrate real world diagnostic testing methods that can streamline your workflow, saving significant time and earning you more!
John explains his 'go - no go' styles of testing, using modern equipment like pressure transducers and scopes, to techniques like relative compression testing and diagnostic interpretation.
What You Will Learn:
Introduction to Modern Testing: Understand the basics of 'go or no go' testing methods and how they differ from traditional, labor-intensive diagnostics.
Using Pressure Transducers: Dive into how pressure transducers can be used effectively to measure and interpret pressures within an engine or system, allowing for quick diagnostics without extensive disassembly.
Relative Compression Testing Explained: Learn how to perform relative compression tests to assess engine health. This method helps in identifying compression problems rapidly and accurately without removing major engine components.
Practical Demonstrations: Watch real-time demonstrations on various equipment, showcasing how these modern techniques are applied in actual diagnostic scenarios.
Benefits of Modern Techniques: Discover the benefits, including time savings, accuracy improvements, and reduced physical effort, that these modern testing methods offer over traditional approaches.
Whether you're a professional mechanic, a student in automotive technology, or just a car enthusiast looking to expand your knowledge, this video will provide valuable insights into modern diagnostic practices that are critical to success in the industry.

The one issue I see is that when connected to a vacuum line with a pulse sensor you’re seeing each cylinder pulling on the intake manifold but you’re not seeing anything to do with the exhaust valve. A pulse sensor doesn’t show true pressure it just reacts to the change in pressure and the voltage rebounds the opposite direction afterwards. Thats why you see the downward slope. The exhaust valve isn’t visible from the intake manifold as the intake valve is closed when the exhaust valve opens.

I have been able to find exhaust valve issues with the pulse transducer . due to valve overlap on engines, an issue with the exhaust valve will be prevelant on intake pulses. if you’d like I can try to share a scope pattern showing an issue when I return from traveling.

Your videos are gold . Keep them coming your channel will explode. If you make them they will come 👍🏻👊🏻

[@electron-john]

thank you for your support

[@sandyande]

Thanks for training John, where do we get access to your EV training online cheers sandy

[@electron-john]

Hi sandy, thanks for watching. My level 1 ev training is on the paid subscription channel. Any of my higher levels of ev training happens sporadically via zoom classes. I will make sure that when I have my next zoom classes I mention it on this you tube channel as well as all my social media pages and website.

[@electron-john]

hi sandy, level 1 can be found on the paid subscriber channel while level 2 and above can be found when I do my zoom classes. I will be sure to mention the next time I have a zoom class on this channel and the website and all the social media pages. the level one is rather long to establish a good foundation which is why it is on the paid subscription side broken down into 13 chapters, the zoom sessions are usually 1 hour long and concentrate more on diagnostic and repairs of various components such as hv batteries, drive motors etc. thanks for watching!

How do I get to your paid channel?

if you watch on a pcthere will be a join button you can click. for some reason it doesn’t show up on mobile devices
