- OK, you’re on the fence about investing in a DSO - Digital Storage Oscilloscope. Or you (or the shop) have one but it’s sitting in the bottom drawer of your toolbox, gathering dust. And it isn’t making you any money sitting idle in your toolbox!
You’ve seen the UA-cam videos - you may have even attended a class or two. You know it’s a valuable and powerful diagnostic tool. You know it can be used to perform advanced troubleshooting tests, like in-cylinder engine diagnostics. And you also know those advanced tests require not only the scope but high priced accessories to go along with it. And you’re excited about putting those tests to work but haven’t really gotten comfortable with the most basic functions of the scope yet.
Before you spend any more money on more tools that will just gather more dust, watch this informative Motor Age/TST webcast - sponsored by Pico!
Pete and G. will show you how even the most affordable scope can be put to work to increase your paycheck right out of the box. Learn how to “see” the voltage drop in any electrical circuit and why only a scope will show you these problems in high-speed circuits like fuel injectors and ignition coils. Know if your driveability concern is a potential mechanical problem without pulling spark plugs, without performing a conventional compression test and without an amp clamp! Learn how to make the most out of the basic tool - and then add to its capabilities with accessories!

4 years later and I can still get something out of it. Thanks guys, G I enjoyed your class at Vision24 as well.
KNOWLEDGEABLE Sir Pete Meier Motor Age and G
Tutorial brilliant 👏 👌 👍
Two great guys God bless you
From Nick Ayivor from London England UK 🇬🇧
Great show gentlemen, thanks for the tool box hand-out.
My old school otc 3840 made me $350 yesterday in 3 hrs troubleshooting intermittent voltage drop. Dealer had already thrown parts and 1k$ at it. This is a very common scenario.
How do you set up a trigger for a voltage dropout?
Thanks for the great information! I would like to see more focus on the actual connections to the car. There are a lot of scope pattern analysis information videos, but not much on the actual connections to the vehicle. Thanks again, great show.
i agree they should focus on the connections
So,you have to think backwards.great!. electrical systems are complicated enough.
Gentleman thank you for putting together the toolbox reference. We appreciate you sharing your experience. Keep up the good work!
Yup! Everyone shows the screen but few talk about why/how they connect to the vehicle. I wish there was a good book about nothing but scope tests and how you might go about setting it up.
@@iam1smiley1 You don't need a book and this is why you can't find one. If it was popular or could raise profitable revenue with such a product, then, well.
What I'm saying is that all you need to do is practice. Practice with your own car on all the different sensors. Play with amplitude and the time until you get a decent wave form that you can record and play back. Sensors are in different locations on other cars are and different than any other car. Get a download of your wiring and sensor location and go to town scoping all the different sensors it's got.
Extremely helpful thank u all👍
TST is the best can't wait to get back to the classes
As always, you guys are awesome. Thanks for sharing your knowledge.
WOW! This video is amazing had to share it and will always share it now as I’ve saved it. Thank you for sharing your deep domain knowledge for us all to learn. 🎉
Oh man I love g! He had such a good class at vision hope to see him again! Also Pete had a great class that had a nice q and a during it that was anonymous!
Quality video best oscilloscope training on the inter webs
My head hurts. 🤯😁 Good video. Thank you for sharing the knowledge with us lowly car tech padawans. 😉
Appreciate the good work fellas. Really appreciate the valuable input. This is coming from Trinidad and Tobago
This is the real world...so learn from the mistakes of those who know! Good Day.
Many thanks Pete & G ... EPIC presentation!
I absolutely agree with one of your fans and I quote him as follows: " There are a lot of scope pattern analysis information videos, but not much on the actual connections to the vehicle."
No Scope to vehicle connections = No Scope readings! Can you help please?
We have an entire playlist on scope use you may find helpful. Just go to our channel's home page!
thanks for the video and handout.
Great video. Thx for all you do to make us better.
Great vid ! Jay.
even this document is late put thanks for good work there is one question about how to know wear the ignition coil number 1 and enjctor number 1
Great presentation. Can you guys a scope class on Escope eltie 4 ?
Thank you
Keep the knowledge coming!
great video even for a beginner like myself. Thanks! Do you have a similar video for a midrange or any scanner !
Awesome video. Thanks!
I love using an Oscilloscope although, I haven't used an automotive scope however, to me, the basic principle is the same, so I don't expect having any difficulty - when I finally get one...which is soon.
thank you very much for shedding light on this topic. I've learned a lot :)
My chrysler dealership recieved a new pico as a "special" tool. I need to learn to use it more . Thank you
Check out our How2 playlist for some tips on set up and signal acquisition!
@@MotorAgeMagazine where can i download the hand out
@@Ranalla651 There’s a link in the video description.
The answer to the relative compression test at 1:05:10 ish is, i suppose, that the peaks must all be within ten or fifteen percent of each other in the group, the same as in an actual?
Thank you.
Thanks
Great work dud
Great vid!
Great information how can I get a copy of the hand out the link no longer works
Thanks
pico is the best
Do you have a video on how to connect the leads to the under bonnet electrical components.
Check out our "How To" series on our main channel page.
Great video! I just picked up an old 1115 sun machine. Maybe you could do a video covering some neat tricks for us old farts. Cheers!
Vintage Video Very interested, and even didn't view 10mins🇧🇸
Is the GM map sensor G showed during the video a good alternative if we can't afford the WPS500? If so, any particular part # of the GM map to use?
If the relative compression test isn't a reliable test for up to fifteen percent of newer cars, what other options are there to quickly check mechanical condition of those engines?
There are some instances where the relative compression test won't display an intermittent sealing issue. If you suspect a weak cylinder, in-cylinder pressure testing would be an alternative to consider.
@@MotorAgeMagazine CYLINDER LEAK DOWN TEST?
@@keithbland5365 The cylinder leakdown test, where the cylinder is pressurized and you listen for the sound of the escaping air, can also miss an intermittent sealing issue.
Been looking for videos like this.
I have a 2015 jeep cherokee with the 9 speed trans. It has the jerky gear charges.
Can scanners do any testing to find if the fault is electrical/ computer or trans.
Thanks
You can when you add a scope to the package. Check out this offer: www.aeswave.com/Transmission-Diagnostics-for-non-Transmission-Technicians-by-Scott-Shotton-p9911.html
i try to hear what you say, i understand 98% of it but i cant keep my eyes off of that yellow gin pole thingy with all those leads. what is it, where can i get one 😍😍😍
That's part of the Automotive Test Solutions storage cabinet for the ATS EScope and accessories. I'm not sure it if is still available. Many techs are building their own using rollarounds and flat-screen TVs or monitors.
Good infos, but it's like the slowmo
Are any of you using mains powered labs scopes on 12V/automotive systems? I have a quad channel Rigol and would like to hear from anyone using something similar. Great video - thanks for sharing.
I've used an old Tektronix 475A. The principles are the same no matter what kind of scope you're using, really.
@@dreddnott Thanks! I was specifically curious about any fears surrounding use of an AC scope of 12VDC systems (loaded or not).
@@AN-kg4ei I'm not aware of any since good scopes all seem to be able to handle both alternating and direct current signals. I avoid using the tektronix now just because of the inconvenience, but it reads everything fine from oxygen sensors to secondary ignition
And I don't think there's any way to fry the engine computer since current measurements are done with an inductive probe.
Are there any books about hooking up the scope?
Thank you both for a great video. I have downloaded and printed the handout. I have a pico 2204a and purchased an 600volt amp current clap to do the battery test that you both have demonstrated. The maxs volts is rated as 20v. Can I use the 600a current clamp with the 2204a without damaging the scope? This is my first scope and I don't want to ruin it. Thanks for you help. I am learning some much from you guys keep up the good work. Thanks again.
You should have no issue using the current clamp with the scope. It outputs a low voltage signal in relation to the amount of current it is detecting between the jaws.
@@MotorAgeMagazine Thanks for taking time to respond. I appreciate the effort you all put into your videos sharing your knowledge. I am learning a lot from them. Keep them coming.
Mi favorite #10
95 chevy g20 5.7L 4L60e tbi
Bad tbi backfire under load only while driving. Compression good. Fuel pressure and vacuum good. Idles fine. Revs up in park fine. Happens about 1/3-1/2 way down on gas pedal. Injector spray patterns look good. Any ideas? What should i check with scope/scanner? Long/short fuel trims? Injector pulse width? Timing at 0° base idle. Advances to 20° btdc with EST
Ever figure problem out on your 95? Also have a 95 with issues. Had similar problem with my 89. Changed egr and egr control valve fixed it. The 89 anyway. 7.4 on both. Tbi too
HOPEFULLY, I UNDERSTAND THIS CORRECTLY 8.5 VOLTS IS THE NEW LIMIT ON THE BATTERY TEST NO LONGER 9.5? HAVE YOU DONE A SHOW USING DVOM WITH A AMP CLAMP? THANK YOU!

Info for Technicians , Teachers & Shop Owners.
Also pay attention to the VET Course,
"Vehicle Electronic Technicians" & the "Comments Section".
Due to the sampling rate of oscilloscopes vs digital voltmeters, a lower inrush voltage can be detected even on the same battery and charging system.
I know you are talking to automotive technicians would you be so kind to show how you back probe the ignition coils for DIYers.
Take a look at this video and see if it helps! ua-cam.com/video/JfGa3hFSg7U/v-deo.html
Mr. Meier are you a USN retired Senior Chief CAPT. William Starsiak Jr. USN (ret.)
William Starsiak Good eye! No I am not. But my son is an active duty Senior Chief.
Do you still need a scanner tool if you have a scope?
Yes - the scan tool tells you what the computer is seeing and the scope tells you what it should be seeing - if that makes sense.
To prevent a running engine on a battery and starter test I use a metal schield on the key. So I can start so long as i wish. A tube with a closed end with a drilled opening to bring the key in. I know, there are many ways but i like my method.
Any chance you have a video on this? This is a great idea
Pico and ase waves are just to expensive. The cost it so high to get what we need. I get to use my scope maybe 1 a month and I had to settle for a hantek witch is just like a childs scop or toy. It's not very good and it drives me crazy trying to set it up.
Buy once, cry once
The hantek is still capable of completing tests and diagnosing faults. It sounds like the problem here is using it once per month.
As for the price of this stuff. It is expensive. But worth every cent.
Nice !
How to chack supply voltage a pizo injector
25:40
When is a good time to use an attenuator, afraid to get into it cause I don't want to fry a $4k+ equipment.
If in doubt, use it. Once you know what voltage levels to expect you can remove it. It won't impact the pattern either way.
Hi. I dont seem to be able to download the toolbox reference. Is it still available please? Thanks.
Sorry, I'm afraid the handout is no longer available.
What is a trigger.?
The link for the handout didn't work for me.
I just tried it. Seems to be working fine. Try another browser.
@@MotorAgeMagazine works on my windows browser. I was using my android phone before. Thank you
Sir my car is has a distributor. How can I hook up my testing equipment in order to do a relative Compression with reference?
Easy! Use any of the secondary leads coming from the distributor. Just know what cylinder it is attached to and use firing order to align the pattern.
@@MotorAgeMagazine my issue is how to scale the capture. I have a hantek secondary ignition pickup clamp. It is attenuated 10:1 i believe. What should be my time and voltage on that channel?
Do you have a Facebook page or group so i can submit my capture to you sir?
@@Usmanthemecano Time base is the same as the amp clamp channel. I don't think that the secondary pickup is attenuated at 10:1 - not enough. So simply set your voltage scale to it's highest setting and work your way down until you have a usable pattern.
@@Usmanthemecano You can email it to me at pmeier@endeavorb2b.com
Prize should have been a slice of pi
For someone not familiar with the conventional way current flows,this can be a real problem; you have to dish out all you have learned and think the opposite.confusing.
What is a scope could you show me what it is

At 33:40 I think you meant in rush current not voltage

I've watched many Motor Age videos and enjoyed them, but the mafia henchman interrupting all the time here reeks of someone who doesn't know as much as he should but always feels the need to tell us what he does know.
I'm an electronics Engineer with almost 40 years experience and work on cars in my spare time so it's always nice to glean information from others who have automotive knowledge, so I skipped through the video.
I stopped when I got to the bit where the guy with the hair referred to top to bottom of the waveform as "peak to peak".
Good info, but having 2 presenters is so distracting. ..
Why Pete take so long to configure the laptop is he confused
You are very loquacious ,,,
Get to the subject & stop talking .
