I can always count on guys like Jim Morton, Bernie Thompson, John Thornton, Dave DeCourcey (RIP), and Brandon Steckler to make me question how I look at things and take a different approach. To me, figuring out the puzzle is the best part of auto repair and that's why Diagnostics are so much fun. Thank you Jim for your willingness to share your knowledge and for always pushing us to be better as an industry.
Not at all sure why somebody would criticize this Free webinar from a man with experience. I have listened to seminar probably 5 times over the past 3 years. The first day after hearing this I was overwhelmed with all the details. I took aim at improving my weakness with using a multimeter. I used one everyday checking good vehicles. Checking voltage drop and amperage became second nature and I enjoyed myself when I found a problem. Now I use a scope fluently on a daily basis, and I still find value in this man's experience. This webinar started a desire within me to not be afraid of what I don't know. Training, patients, and practice, combined with a positive attitude has made me a 1000 times better technician.
I will pass your nice comment on to Jim...he appreciate it. thanks for watching....If you have not already subscribed to our tstseminars RU-vid channel please do so .
Great information! Thanks Jim. I’ve watched more than once, as well as attending one of Jim’s seminars in person. People travel and pay hundreds of dollars to attend these courses. This is out there for free. Take advantage of it!
This guy is one of the absolute best out there. I only wish I could get to be in the same room with him to learn more. Awesome seminar and hope to see more.
Thanks for the response, I'll be in Chicago in about three weeks at Automechanika doing 2 presentations on ignition waveforms (one is already completely SOLD OUT). Would be GREAT getting together again with the TST group and doing the 4 night tour on Ignition waveforms. We will have to see if we can make it happen.
I am absolutely amazed at the breadth and depth of information, knowledge, and understanding Jim Morton shares, in this freely available seminar. I've worked with engines all my life, mostly pre-coil-pack types, and I learned more factual information on how to quickly and accurately diagnose an engine problem in newer (and even older) engines just from this using nothing more than waveforms, than I would have thought possible. It is extremely hard to find good information like this today, and frankly what this man knows should be the Bible for vehicle engine diagnostics.

This is perfect! I was looking for a good resource to learn this stuff after finding youtube videos and articles going into ignition waveforms but all I could find was surface level information. This lecture is very good! Also love the part about looking at amperage rather than voltage, it is almost always more useful! Voltage tells you very little. One of the first struggles I had when starting my career in debugging was people telling connections were fine because they had continuity or voltage, but the wires had been damaged and had such a poor connection they couldn't carry any current. I'm sure I'll watch this 3 times to absorb all the details. Thanks so much for posting this! It means a lot to me and furthering my understanding.
Ben that's great....If you have not already Subscribed to our tstseminars RU-vid channel please do so. Interested in more training? Go to www.tstseminars.org and www.attstraining.com
Jim is the king; always good at tying in theory with a pragmatic approach. It's been over ten years since I had an L1 class that Jim guest instructed a few days of, and this stuff still gets me going. Thanks for the watch!
I loved my Fluke 97 and was disappointed when Fluke no longer supported it. I did find a used one and picked that up whne my was not repairable, that period of time being without it was tough. I do have a Pico 4 channel scope...very powerful ....using the Fluke taught me the skills to use the Pico. Great to hear you mention running cars on propane, that has been a test I have used for decades to determine if the fuel system is at fault. Fantastic seminar!!
Every few months I keep coming back to this video and getting something more out each time. Now I always check thebattery starting and charging voltage every time I do a diagnostic by using my scan tool to graph the ECU voltage PID.
Dios les continúe bendiciéndoles grandemente Muchísimas gracias Ats for a free seminario para nosotros. Gracias señor Morton por si tiempo y conocimiento.
Jim, Thanks and you should not have said that to me about if you can explain anything further to let you know ! I'm a firm believer in picking a man's mind with your experience for I could learn what you learned over a life time in a fraction of the time by listening to you and trying to understand what you explaining and retain it ! Very kind of you for offering ! I'm having trouble finding more of your seminars/materials online. Is there more out there ? Once again Thanks !
Not yet, I didn't post this one, I was doing a presentation for TST seminars and they asked permission to post it. Where are you located at? I'll be in a lot of cities in 2017 doing more presentations, I'll keep you posted where I'll be if interested.
As a mechanic who has been a keen user of spark line analysis since the 1980's I found the video interesting. a few bits I diverge on but otherwise good info.
Mike thanks for your comment...If you have not already Subscribed to our tstseminars RU-vid channel please do so. Interested in more training? Go to www.tstseminars.org and www.attstraining.com
That's GREAT, Hope it helped and you learned something. FYI - I have been writing an UPDATE to this training on the newer Ignition systems out there. Should be presenting the training soon
Autel BT608 is the first tool I hook up to check battery, starting and charging systems first before proceeding to codes or drivability concerns. Seen bad battery and alternators causing crazy problems so many times.
I knew a lot of this stuff........because I had Mr Morton for engine performance 1&2 at ATC 😏A lot of the stuff that I do on a regular basis, I learned in his class. This is a great video.
Thanks for your comment and for watching...Jim is a great instructor. Hey if you have not already subscribed to our tstseminars RU-vid channel please do so.
My only complaint about this video is that it was too short! :D You're the kinda guy I'd love to sit down with for a day and just pick away at your experience. Awesome job! I've been needing to get better at secondary ignition analysis. Especially on partial misfires or coils that are just starting to fail. The shops I've worked at only understand "unplug it" tests or "swapping parts" tests. They generally view scopes as taking too much time because they can take 5 minutes to set up. Even though they'll gladly spend HOURS throwing parts and flipping through Identifix... Every time I go to grab some secondary waveforms I'm usually in a mad rush before the boss comes over and tells me to quit wasting time. I usually just have time to save some captures that at least I can view later. It's so frustrating looking at a capture that's showing a BLATANTLY OBVIOUS problem but I hadn't done enough research to know what it's saying... Your explanation of using the spark line to determine of the problem is internal or external to the combustion chamber is such a game changer. I imagine that way too few people know about that. I only happened upon this video by chance. And also your mentioning of the carbon on the intake valve acting as a sponge was really cool. After all, that's what an EVAP charcoal canister does... I hadn't thought of that but now I'm going to try and keep an eye out for it. Thanks again for the great info.
Glad it was helpful, Let me know if you think I can help you some more. i will be doing more presentations with TST in the near future, help you can attend one of them live.
That would be pretty awesome but I'm up on the west coast of Canada so we don't get too many top notch seminars come through this way. Which is why I'm forever grateful that people put the time in to release stuff on youtube. The availability of quality information online just amazes me. Makes me happy to be a tech in today's age. I can improve my skill set by sitting in front of my computer eating my dinner and drinking a beer! In a couple hours of comfort I can learn skills that might have taken months of blood, sweat and tears to develop back in the day. Especially since it's hard to try new techniques and analyze new data when you're on the clock and bosses are yelling about efficiency! Thanks again for the great video.
Thanks for the reply. We do get in Canada from time to time, I did a series of presentations in Winnipeg. Also there is a GREAT annual training event that goes on in Seattle every year.
there is so much information in here that I've been stuck on listening for days. this is like my third day and I just keep listening until I have it burned into memory. it's the vast amount of years of knowledge put into a small time that makes it impossible to get the first few times
Jim, GREAT video !!...between you, Paul Danner, Dave De Courcey (R.I.P.)....his outstanding video on "misfire diagnostics strategies" and Jerry Truglia, I have learned SO much in the last year...I just picked up a Picoscope last month and I'm trying to learn with it almost every day !!

If you think I can help you out all with your new scope, Just ask, My Friend. LOOK AT AS MANY GOOD CIRCUITS AS YOU CAN, Then the BAD circuits will be VERY EASY to identify.
Thanks for the quick reply Jim !!...I was doing a cam/crank correlation on my "guinea pig" 2001 Corvette last week with my new 2 channel Picoscope...when I used the "auto setup" for the test the Cam waveform was "cockeyed and not a nice squarewave...when I did the setup "manually" on both channels the Cam waveform was perfect....scratching my head...maybe software glitch ??...THANKS Jim !!

I've used the Vantage kv module for years. When I show it to another mechanic, they laugh.I could analyze a driveability problem in a few minute while they took hours.I also use the the kv probe (Waekon) for a quick cop check.Wish I had this info years ago.Or perhaps if I understood the waveform better. Thanks, Jeff P.S. I liked the NO intermittent statement:>)
The original Vantage was an awesome diagnostic tool If you REALLY understood what it was, then the KV probe put it over the top. Thanks for the response Jeff
thankyou jim very well done I remember tom McKenna when I used to watch AVI training videos just watching him on video I was very impressed would have loved to have met him thank you mark

@@jimmorton3009 Yes but this is a whole new world now, you look at 4 brand new NGK's that have been fitted by another shop and think, it cant be them, they are good quality brand new plugs so it throws you off course a little but as you say its a lesson because the next one the plugs will get checked 1st
@@steveb936 I hear you, Steve. I have already pulled 4 spark plugs out of the boxes and could easily see they were manufactured by different companies. Like our job isn't hard enough already.
Is this 1 to 1.5ms burn time under all engine loads or during snap throttle testing. I've seen al kinds of numbers from 1ms to 3ms I try to compare to other cylinders
YES, Good point, the cylinder will and should become momently leaner during the Snap Throttle, and as you stated, Comparison reading is always the way to go.
Great video!! Are you saying a clogged injector & Intake leak will appear the same on the lab scope? I thought the (clogged injector) high kv reading was unique to injectors?
They would both cause the firing KV to be high, BUT as you take the engine RPM up, these two problems would start to look different, the clogged injector would start getting worse where as the vacuum leak would start looking better....... GOOD Point Flatrateus
Go to hear...as you see below Jim will answer your questions...thanks for watching... make sure you tell your friends and sign up to our tstseminar RU-vid channel
Sorry I'm late to the party but I'm a little confused on the determination of extra-cylinder resistance based on the initial slope of the spark line: Am I to understand that (high firing line kV)+("initially" decreasing spark line kV) is indicative of resistance external to the cylinder? Is that what you meant by "...jump out early.."?
Thank you so much for this video. There is a wealth of knowledge here for sure. What do you look for in a 2008 Dodge 3.7L system that only has a dead miss at partial throttle around 55 mph? It's very hard to duplicate while driving and I can't get it to repeat while standing still. Customer says they have a transmission issue. I see mode 6 information telling me I have misfire history on cylinders 2,3,4 and 6.
If I had this vehicle in my diagnostic shop, I would look at it while on the Dyno. If it was a mobile diagnostic job, I would be "Power Braking" the vehicle while watching the Ignition. HTH

Jim, I am new to the lab scope and just obtained a older Snap on Modis. I have watched this video several times and my question is if i attach low amp probe to negative feed on ONE COP then this will show me all COP wave forms or do I have to do each individual COP ? I am sorry if that is a stupid question but i will not know unless I ask. Thanks
There is NO stupid questions, The fact that current is on both the power side and the ground side of a working component, by putting your Mini-Amp probe on the power side and opening up your time base, you can look at all of the cop coils at the same time. because the same power supply feeds all of the coils. The only new issue is, when you have a 3 or 4 wire COP, the driver control unit is placed in the COP coil it self, the PCM module only supply's a digital waveform to open the coil.
Jim, At 43:29 of your video can you tell me what probe and where it is placed on the green and yellow traces opposed to 44:08 where you state the amp clamp is used for green trace is on negative feed of coil then where is the yellow trace coming from? Are you back probing the same coil on the + side ? Thanks
Just went back and looked at where you were talking about. At 43:09 I was showing Voltage over Time of the Primary and the Secondary of the same cylinder, at 44:08 I'm showing Voltage over Time and Current over Time of the same cylinder. My point being that Voltage over Time is a COMMAND, But Current over Time is the actually work being performed. I hope this Helps.
Thank You, Hope you learned something from it, I have been putting together information on the newer Ignition systems for an updated class, should be presenting it soon
I just saw super Mario video and it was a BMW N55 engine misfire one cylinder and it had turbulence on the ignition waveform at the right side of the sparkline, and another BMW N55 had turbulence on the left side of the sparkline both had the same problem the spark plug.
Perhaps one cylinder had an issue with the spark plug on the electrode side and the other had an issue on the insulator/porcelain side? I hadn't seen that particular Super Mario video, but that could explain why they showed up on different sides of the waveform.
It is a shame that the sound quality is poor . I cannot understand what is being said some of the time, partly because the speaker gabbles. Quite interesting nonetheless

Could someone comment on why a banana jack to bnc is a superior connection than a bnc to banana jack? I am new to scopes and just bought a pico with the pico low amp clamp and added a bnc to banana adapter to use w/ my DVOM and am wondering if i made a mistake going that route.
It's a matter of choice and the unit. Banana jack is used on labscopes that are made by Snap On and OTC while a EScope, Fluke and PICO use BNC as many true labscopes do. Your good with the connector... the issue you may encounter is using the clamp on the meter. Make sure to inserted the ends into the Voltage and Com jacks. The conversion rate at the first setting is 10mA equals 100 mV = 1 amp. Make sure you read the number correctly on your meter...try it on a circuit you know has a specific amperage so you can see the reading on the meter. Hope this helps....look for some of our labscope and amp clamp videos. Thanks for watching....If you have not already Subscribed to our tstseminars RU-vid channel please do so.

Jim Congrads...You can purchase a low amp clamp from www.aeswave.com the PDI brand is not expensive and work well. You may also wan to look at the high current clamp so you can do starter draw and Relative compression with an amp clamp. Take a look at some of the other video on labscope on our TST channel.

I will send your question over to Jim so he can answer you. If you have not already subscribed to our tstseminars RU-vid channel please do so. If you interested in more training go to www.tstseminars.org...thanks
Yes, leaner air fuel mixture would be a good example of higher internal resistance, But as far as compression it would be the opposite, Higher compression would be harder to fire, so that would be included in the higher resistance. ALWAYS remember that Leaner air/fuel mixtures and Higher compression are the two most common reasons for hard firing of the combustion chamber.
We don't have it but you may want to contact Jim Morton...he does monitor this video...if he does not get back to you email me your information and I will email him...my email is gt@tstseminars.org. thanks for watching...If you have not already subscribed to our tstseminars RU-vid channel please do so.

I look forward to getting back on the path and work on more Training and a possible Training manual. Thank You for your interest, STAY SAFE
NO, that waveform is the current going through a fuel injector. I'll be doing 3 presentations in Chicago, 2 are the same presentation due to the demand. There are on Ignition waveforms and what the waveform is telling us about the combustion chamber. The other one is on five exhaust gas analyzing. Hope to see you there, Please introduce yourself if you are going. If you tell me what your interest is in the training, I might be able to recommend some of my fellow trainers that will be there.
John, Hit my e mail at matsauto@gmail.com, I've been asked enough times from your area that I think we can make it happen with a presentation out there.
John, we might be closer to making something happen in your area, I will be with Paul Danner (aka Scanner Danner) in Kanas City at Visionkc in March. I'll be talking to him about a possible seminar together for your area. I'll let you know.

On some vehicle any mechanical noise can cause a knock sensor to pick up the frequency. I am sure that Jim Morton came across this and knows what he is doing. Hope that helps...If you have not already subscribed to our tstseminars RU-vid channel please do so. Interested in more training? Go to www.tstseminars.org
The older knock sensor only reacted and know a Metallic noise, think about how manufacturers told us to check for proper operation ? Use a crow bar and a timing light...…. I have also seen where a pick up with a trailer in tow, has caused the same reaction. the metallic frequency travels through the frame of the vehicle.
At this point ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-yCchGNQEMdE.htmlm59s Mr. Morton kind of derides looking at spark color. I've really wanted to know how important or useful color is at various air gap widths, but I've never found any definitive proof. Since I know that blue light has significantly more energy than yellow or orange light I've assumed that blue sparks were stronger and better and indicated sufficient power to drive combustion. Maybe the kind of people seeing this vid could provide some better proof of this variables relevancy.
For real though. This could have been a very focused 45-minute talk. I'm gonna watch again and take a shot everytime he talks about his resume. I may die
There's mixed signals about this guy, some say he's awesome, others say otherwise, hard to tell the info being spread is actually legit or just a bunch of double speech . . .
He has good info, the only issue is he tends to go on a tangent at every opportunity. So I find it difficult to tie the info together. But hey, it's a free seminar and beggars can't be choosers.🤷
man you are good and you are knowledgeable,but you are teaching college physics to kids that can barely pass math 8,its a problem in the auto industry now,they are taught the scan tool will do it all
How true Jim! Also as you like to say... I'm glad I didn't know you and your shop does all the diagnosing in Phila region as you comment on at the 25 to 32 second spot. Because we diagnosis vehicles all the time and are also in the Phila region and you haven't been in my shop. Go Figure ;) Maybe I retained a lot of what Tom taught two of us that work in our shop. Enjoy your day Jim!
