Picking up the secondary ignition pattern using an oscilloscope

This video was created to show how to pick up the secondary ignition pattern using a simple homemade tool and an oscilloscope.

one less day to lose...cause we learned something! didn't we? . very thanksfull for the tips and the teaching. I'm right away subscribing myself.. thanks for sharing the real treasures, the usefull ones and those we can carry on we us

[@SchrodingersBox]

loved that trick with the wire on the COP. I'll have to try that!

[@rogersy7209]

Does it really work? The video did not show actual pickup secondary ignition voltage. It only show stored display of secondary ignition voltage...

[@MarzNet256]

Cool. I put a US quarter on a coil and laid a backprobe pin across it and got a very clean, detailed trace (pico 2204A). Car is a 2006 Matrix (Corolla).

[@sollykhan2385]

Thank you for posting this great video, that wire loop is simply awesome, man why didn't l think of that myself?? Lol🙂 please keep on posting these fantastic videos, Bless 😇

[@mvlad7402]

Amazing content! Very useful!

[@gmytfan]

Learned something new today thanks for the tip !

[@iriejam2164]

Valuable information. Thanks for sharing.

[@human2571]

You are great sir and thanks for the trick.

[@grecomillar5031]

Hi, Thanks a lot friend, I was looking for this. Greetings from Chile.-

[@shellscripting9526]

Very neat arrangement. Thanks

[@Atetus94]

Thank You very much - more about using oscilloscope to diagnose cars!

[@lindsay.newman]

excellent explanation, thanks

[@arnulfotapia]

It is a good idea, I put the clip embracing the SPARK PLUG cable and the signal is very rare, looks better as you do, I'll try, by the way I see it is mainly good this method for COP systems THANKS

[@valdirmartins467]

Very very good, I like this on.

[@michaelovers688]

Good video Zep

[@kalindambozi2356]

Best tip.

[@vtailv35]

I'd like to know where you can buy the ignition clamp that you use on the bolt, I've used high current clamp pain. Or maybe it can be made to use with pocket scope like one I have DS212 which works great , I didn't know OTC made a scope for that cheap, hope someone can answer good vid !

[@jimcarey160]

the video mentions getting an OTC 2 channel o scope for 50 or 60 dollars. PLEASE tell me where? I can't even find one like in the video. Anyone know or have a link?

[@ihatekate08]

Maybe it’s just the format of your scope, but that looks like an open secondary to me. I see a firing line and no spark line. The coil is building kV, but it isn’t going anywhere

[@jackjohnson9989]

Why no response to the observation above? And two years have elapsed without any challenge or reply? Damn it! Seems like that fellow....think they call him scana-spanner(?) ....been misleading thousands of us all along!

[@johnnytacokleinschmidt515]

Definitely there's a burn line. It's just at a very low amplitude compared to what we usually see.

[@dirceulucas1426]

mmmuito bom esta pinça de igniçao

[@chevy5165]

Very good, how to make these plates

[@arnulfotapia]

Hi, could you tell me why this signal is so long and because it has low level in the burn section, is this normal ??, thanks

[@johnnytacokleinschmidt515]

His chosen sweep rate on the screen. It's triggering on the firing line and then there's a long dwell time you're not seeing. The amplitude of the burn time section looks low compared to what a conventional ignition and scope would usually show.

[@dalenassar9152]

GREAT MEASUREMENT!!! I have one question about the graph, timestamp 4:11 1) What is the typical peak CURRENT of the 18kV spike? ...been looking for spark current for MANY years!!! no luck! THANKS SO MUCH!!!!

[@AlexAwwesome]

around 6 mA

[@alexwade9921]

An interesting take on the technique and one I’ve not seen before. The original probe you start with is called a capacitive pickup though. It has some RC network between the clip end and the scope. You’re just connecting that in series with the lasso wire you’ve made. I doubt that its necessary to ground the lasso wire as long as the pickup you’re joining was still grounded. I suspect, in fact, it would be better if you didn’t.

[@aseredy]

I may be wrong (I'm new to EE), but grounding the capacitive sensor increases it's sensitivity, because you're including the the surface area of the ground network. I'm still trying to make heads or tails of it all though...

[@Paint0nBrush]

@@aseredy I think grounding the wires creates a polarity through the wire instead of eddy currents. It would filter noise too. i bet he could run 4 wires from each ignition coil around that bolt and see every spark's relative waveform on a single probe.

[@paulmeynell8866]

Do you know the mv or v that come off of those clamp type leads as I have it connected to a lab type scope?

[@paulmeynell8866]

Fitted new magneto now working perfectly. Many thanks. Loving the videos

[@KlintonMcD]

We're in 2022 and this guy's in the year 3000.

[@paulmeynell8866]

How long was the spark? You can’t see the time per division in the picture?

[@ryankirk8211]

i make the wire one in ur vid on my 2007 ford edge why ant i getting a diff pattern than u are please help

[@Ashroyer86]

Is an attenuator needed?

[@mr.technician2638]

Does this safe for scope without attenuator?

[@ryankirk8211]

what settings are. u using

[@rogersy7209]

Just wondering about the yellow wire loop for inductive pickup of high voltage signal... The end of the wire connected to ground... If the yellow wire clip was really connected to the loop end... High voltage signal should be dissipate directly to ground... How would scope probe detect the bolt that was between the continuos yellow wire?

[@ihatekate08]

Because the scope picks it up before it gets to ground. Look where the capacitive pickup is, it’s in the middle, not the end. So, it’ll travel from the coil, to the scope, and then to ground

[@ihatekate08]

At least that’s what it looks like to me

[@drhody1967]

You are correct! you could put the capacitive pickup anywhere on the yellow wire and it would work.

[@keving52002]

That burn line seem way too long.

[@mutsuoiwatsu8184]

[@OnePercentSociety.]

And after 3 hours of diagnostic time you can go recommend the one spark plug that's bad...... Genius

[@hunterperformance3424]

Instead of doing that stupid wire trick just use a primary scope and read the primary side it’ll be the same waveform just downscaled

[@mandytuning]

Cause you wanna see the secondary.
