Compression tests - Conventional vs. Labscope
Brandon Steckler compares two tests in this recording.
One being the conventional method of compression testing vs. a more modern version called relative compression testing. When beginning your diagnostic approach on any diagnostic routine, it is always best to develop a route to travel early in the game.
One early step in that approach when diagnosing a misfire should include a relative compression test. This test is non-invasive, very quick and powerful.We want to know early on if we suspect there may be a mechanical failure or not before performing more invasive tests.
Thanks for watching!
Some very big names in that video, a great example of non intrusive testing. Here's an engine with a fault using the same test. youtu.be/_e-fJHEyPxA
I really hope to meet you, Steve...”CHEERS”!
If you're ever in the UK we must meet up 👍 I'm hoping to come ride along with Keith DeFazio in the spring. Working with him on completely unfamiliar vehicles will be a true test of my fundamentals 😮
That ride along sounds interesting, might need to bring a camera or two to document this adventure! Do you have a date set?
It looks like end of march, hopefully to coincide with TST. I can't think of a better way to stress test my knowledge, I'm used to being under pressure but imagine working under Keith on completely alien craft. Awesome.
Count me “IN” STEVE! I’ll be there, if you’re serious....camera in hand!!😬
I've committed to it, the hype train is rolling 🚂🚂🚂
I assure you, you WILL learn from Keith DeFazio, a true craftsman!
Very well explain process. Thanks for taking the time to make and share the video.
What a GREAT way to start off the New Year with. Brandon’s video can be a real time saver when trying to find the area of the driveability problem. As I’ve said in many of my presentations, most driveabilty problems will fall into one of three Funnels: Fuel Delivery, Ignition related or Engine Integrity. Finding the correct funnel is done by what I call General Test (G’s), then when you have
BTW - I ALWAYS wanted to meet those 2 techs in the ASE questions, you know Tech A and Tech B, that all they ever do is stand around and DISCUSS things??? I think I saw them in that video in the background Discussing some of the questions on the ASE exams.....LMAO
EXCLLENT POINTS, Jim! Thanks for including that. I would love to have included those points in the video as well. Would certainly enhance the demonstration!👍
You Did an AWESOME job on that Video, and even introduced us all to Tech A and Tech B in the background.
Hi Brandon, The mirror of your face in the screen of the scope near the end is brill. Nice touch. J
Thanks Jeff, courtesy of my good-buddy, Chris Martino...he has some cool camera skills
Another tip I like to employ that is equally as valuable as AC coupling, is to invert the scope leads on the battery, this will allow it to appear like a conventional RC test with an amp clamp. Great video Brandon! Glad to have you on the TBT team!
Keith, Thank you, You bring about another great technique!
Great explanation for those who aren't doing this testing method. I know Brandon isn't very tall and he is a bit younger than me, but watching him use such short extensions just sent pain down my back...I like to not lean over when doing plugs if I can get away with it. Keep up the great work my friend.
