We will focus on the physics and learn from it together. To memorize how waveforms should be exhibited is not practical. It's much more efficient to understand why the waveforms present as they do.
That’s a really REALLY GREAT presentation ! You’re making learning easy ; thanks to the teaching techniques and communication skills and visual graphics !
Yes I agree. So many that instruct tend to leave out certain information and details that are very important that coincide in/of the process, as if the student/viewer should already know of it. "Like duuh" or "Hello Mcfly!!" Or the teacher isn't as knowledgeable and/or experienced on every aspect of "said" operation of that particular part at hand. I know when I'm learning a new diagnostic procedure from reading and/or watching multiple videos to get every contingency and not miss anything, I'll go try it on my car but I find at times I'm not getting proper or any results period at times. "Are my tools or equipment failing?" "What am I missing or doing wrong here?" After many more hours researching I'll find that one finite detail in the process to be aware of that answers everything. Maybe, sometimes 1 out of 100 instructional explanations will have that very important, finite detail that solves all of it. Anyways, VERY well done! Thank you.
Thanks for sharing. I too have this 'mossoak' kit that was bundled w/ my Maxisys Ultra, making it a screaming deal (plug: aeswave). In this video, it does mention the attenuator, but when talking about the primary side of the coil. Not sure when to use the attenuator. Primary, secondary, both? Seems to me it would be best suited for secondary ignition due to it being high kv but it wasn't shown being used in this video. Does this mean that this is because the wand has a built in attenuator, and the scope setting automagically adjusts for it? By the way, there were no attenuators in this kit, however, in the Maxisys Ultra there were two. Thanks.
Great question: The Autel MS919 kit includes two 20:1 attenuators. They are utilized when obtaining voltage acquisitions from a circuit with an inductive device as some can kick voltage up as high as several hundred volts. Even a small relay coil generates an inductive kick, although not nearly as high. We don't need an attenuator for secondary ignition events as they are typically captured capacitively. We affix a capacitive probe to the exterior of the ignition cable delivering the spark, or with a wand like exhibited in the video. The signal induced in those devices is proportional to what is actually traveling within the ignition cable, meaning it is not a direct voltage measurement.
Thanks @brandonsteckler3417 , you made it simple to understand. Nice to see the origin of where the energy comes from and how it's plotted out on the screen. Are COP paddles applicable to all styles or are some just to insulated to get a useable reading? Can you give an example of when this might not work?
Hi, Great question! Some COPs are very well insulated and pose a challenge to obtain a usable capacitive waveform. Honda, for instance, has very heavy nickel-plating for insulation which can make it difficult. In that case, i step the coil out of the spark plug wells (using a high-tension cable) and allow the paddle to obtain the waveform from the cable.
When I started as a technician back in the 70s at a GM dealership. We had one large scope on wheels it’s was used only for this type of analysis. Today it seems the scope is the new test light. I left working as a technician and joined the military and got away from automotive work. Today I am learning everything I can . Fun fact every time I hear plasma I think of blood plasma. 🤓
If the burn-line starts higher on the firing line, it means there's resistance in the secondary. But what does this means in practice? Could this mean faulty COP if all the other 3 coils(4cyl. engine) display normal waveforms? I always enjoy reading your articles in MotorAge magazine!
For instance, if there was an additional air gap (like a damaged COP boot that won’t properly secure to the coil) the spark kV point would be elevated. You can experiment by recording the data as I have and slowly pulling the COP out of the spark plug tube of the cylinder head. However, be cautious as this will also elevate the firing voltage and could damage the coil/ create an additional path for spark to seek ground (insulation breakdown)
@@brandonsteckler3417 I have been trying to find the answer to this question. Thanks!! If the spark KV point was lower on the KV inductive kick line, what could that mean? Also, a high upward spike at the end of a burn line could indicate lean, right? What about a large downward spike at the end of a burn line? What would that tell us?
@@Z14kt12timandjes1 , These are all great questions or require a little bit of explanation. If you can bear with me, I’m assembling a class that should be ready sometime early in 2024. That will give me an opportunity to address these questions properly.

Go through all the waveforms and analysis of. Make it a series, I'll watch.

what a fantastic video!!

Excellent video my friend. Keep up the good work
Thank you!
Great information
Thank you!
Fantastic teacher! You are on the level of the lexus engineers at lexus corp here on east cost!
Thank you, Jason. Brandon has many years of practice but it's simply a matter of understanding how things function at their most basic level.
👍 thanks for sharing this valuable info!
My pleasure, thank you for watching!
Thanks for the update. I've seen COP coils with 4 wires. Is that the wire that "sees" the spark plug firing event and reports that to the ECM or PCM?
You’re very welcome. Some manufacturers utilize a 4-wire COP:
-voltage supply
-ground supply
-command
-feedback
Exelente la informacion muchas gracias
Muchas gracias!

Will there be any 3 phase motor diagnostic videos? Used in fuel pump and hybrid
Hello, Pete covered some of this in The Trainer #138 (th-cam.com/video/6ni2XVXDtcE/w-d-xo.html)
Do you have any videos where you use this equipment?
Hello, Brandon is developing an ignition waveform analysis class currently and videos will likely follow. stay tuned!

@@brandonsteckler3417 Sounds great. Looking forward to it.
Great video sir. Does that cop waveform at the end look a slight btut rich to you? Spark line pointing down a hair.
No, if I were to zoom in and view a tighter capture, it would look more accurate.
Interpreting these waveforms takes practice.
Thank you very much
