    Awesome tip bro. Cant always getting a clamp in certain areas so this could be really handy. Good work bro

      It has helped me out a few times in a jam, especially when my SO amp clamp decides to conk out. Hopefully it will help others out as well.

    You can do the same for a relative compression test, great video thanks for sharing!

    How did you discover this? Interesting... 🤯

      I originally found it playing around with the first scope I had and clicking buttons to see what happens 👨‍🔬. Didn't fully realize what it meant at the time but started using it later.
      Keith recently brought it up again and it was a good video idea so here we are.

    Fantastic info. I can already think of a few application i can use to try this on. Thanks for sharing.

    A new approach, at least for me. Thanks for the information.

    Awesome demo sir

      Hopefully it can help you out of a jam sometime Corey. I've used it from time to time in a pinch.

    New to your channel and glad to see that their techs out there willing to share and teach other techs. Thanks, much and will be following 👍 being new to the world of electronics maybe someone can give a quick answer to what AC Coupling is or a good video to watch. Thanks in advance 👍👍👍

      None of us would be where we are without those who came before us passing the knowledge on.
      We have a responsibility to help the techs around us who are motivated to get better.
      From there this group has to pass it on to the next generation and have them carry the torch.

    Great demonstration of Ohm's Law: voltage drop over upstream resistance is proportional to the current. Most often used for the relative compression test without the amp-clamp, but looks like it works for 3 Amp circuits just as well!

    Very interesting my friend. Thank you for sharing 👍👍

      Ramon, I'm glad you enjoyed it and hopefully you can use it some time. I've used it right at the fuse boxe sometimes if I don't have the right adaptors or just to save time.

    Thanks for the trick, now I just have to look how I ac couple it lol

    Any kind of John Deere specs I can get is a keep. We have several new gators in the fleet. So this will come in handy one day.

      Oh and the scope technique is brilliant man

    Gonna have to try this out...interesting 🤔🤔🤔

      Drew, use away man, it may be useful in the future. Maybe something you could teach the other guys at the shop 👍

    I wonder if a microphone sensor type could spot a bad pump ?

    • @ScienceOfDiagnostics
      @ScienceOfDiagnostics  Před 5 lety

      Definitely in theory it could. You would expect different frequencies and resonance depending on pump condition and how hard it is working.
      You would want to have some known good waveforms to start and experiment out from there.
      Only way for us to know is to try it.

  • @PaulysAuto

    Great video Chris, my brain hurts now trying to think if a resistance measurement could help to solve for Amperage. I'm not sure how to do the math or if using the AC voltage measurement in some way would work?🤯 But, it's interesting stuff nonetheless!
    Way cool tip on seeing this pattern similarity in the amperage waveform and AC voltage swings in an AC coupled mode!
    You're smarter than you give yourself credit for and I'd imagine you will find a way to figure out!
    Take care man and have a great weekend!

    • @ScienceOfDiagnostics
      @ScienceOfDiagnostics  Před 5 lety

      If I figure out a way it's because I annoyed Dmitry L to make a video on it 🤣.
      I appreciate the kind words though. Just another tool in the box.

      @@ScienceOfDiagnostics yeah it's funny how much a guy wishes he would have paid more attention in algebra 22 years later😂
      There's gotta be someone out there with the answer I'm sure. Anyways, very cool stuff, thanks sharing this!

      Let me introduce you to NancyPi. She will get you back up to speed on all the math you never knew you wanted to know.
