I sincerely hope now or in the future, YT generates you a stream of income that makes it worth your while ( or more ) to keep bringing us valuable content. People don’t realize when you’re filming and editing, the shop income is on hold until you get back to actively working on the vehicle.

I would absolutely not be able to accurately and consistently diagnose modern cars without my scope! I use it way more than a meter. For the jobs where it's not convenient to drag out a laptop, I have a little battery powered 2 channel labscope. It's just as convenient as a meter, but way more powerful! With modern canbus systems, there's just no way to go without a scope, and a quick secondary ignition waveform, has put me on the fast track to fixing many "unfixable" cars. Every tech needs to get a scope, and learn how to use it! Great series!

Reminds me of something that Scanner Danner said a long time ago that resonated with me... "Your customer is not full of crap". They don't keep bringing a car in and paying you money for fault that doesn't exist, anyone in the industry knows intermittents are the hardest thing to find/duplicate and just because you can't see it doesn't mean it's not there. Great example of picking up an intermittent fault!

This is the type of shop I’d love to work at and hone my electrical skills. You don’t find many shops that do this in-depth of diags anymore. I thought I’d see scopes being used at the dealership and everyone told me I had an old way of thinking. I think the correct term is a precise way of thinking.

Cool. I put together a budget DIY diag/scope setup: 2012 MacBook Air with pico 7, pico 2204A, Hantek 3m 30A leads and 20:1 attenuator and CC-65 amp clamp. Fuse buddy, OBD2 breakout box and back probe kit, alligator clips and wire piercing probes. I also have an xTool A30M and a Foxwell N301 reader. You don't have to spend a ton to get started in diagnostics.

I WORK AT A NEW CAR DEALERSHIP NOW ,,, MOSTLY NISSAN AND KIA AND I CAN SAY YOU'RE TOOL GAME IS IMPECCABLE . I KNOW THE TECHNICIANS THAT WORK AT YOUR COMPANY ARE VERY GRATEFUL TO HAVE ACCESS TO THE ADVANCE TEST EQUIPMENT . PLEASE KEEP THE INFORMATIVE TRAINING VIDEOS COMING THANK YOU SO MUCH FOR YOUR TIME !!!

What a great video showing how difficult it can be to diagnose the current and always evolving issues with car repairs. I’m close to retiring as a 40 year master tech ( factory certified in Toyota,Nissan,Chrysler and BMW). When I started at Datsun we had points and condensers with carburetors. The bottom line is that it was much easier to diag and repair than the current vehicles but the compensation for the mechanics has not increased at the same rate and that is why there are so few mechanics entering the workplace. Take care Sherwood you’re an absolute pro. Much Respect from Pismo Beach California.

I am slowly starting to understand scopes. GOOD NEWS, HONEY! SHERWOOD SAYS I GOTTA BUY A SCOPE TO WORK ON OUR THREE CARS.

Nice, you can also add a heat blower or a upside-down can of air duster to simulate failing conditions.

Outstanding Sherwood, really loving this new series. Thanks for sharing.

Great series. Keep them coming.

I, personally, would have swapped relays with another non-critical system first (perhaps the horn if they shared a similar relay). This could be risky as the problem might be inadvertently fixed should the problem lie with the relays blades. But, if the alternate system (in this example, the horn) began exhibiting issues, then I would be confident it was the relay. If the problem persisted with the latch, I would then be more inclined to pull out the lab scope. Probing at the relay to monitor both power and control circuits was a smart move. I agree that a multi-meter could not begin to display the detail needed for this diagnosis, and the lab scope nicely demonstrated a visual representation of the issue, I don't think my lab scope would have been my 1st go-to in this case.

Love your videos. Learning a lot.

Loving the Scope series!!!

Excellent demonstration.

Great video as always.

Great diag ! I like the scope work very informative

Very good I have been using lab scope since the 1970s before they were dsos a little trickier to use back then put one there was the problem you definitely saw it, the name of the scope was a tectronics

Excellent work once again Sherwood! This series is great, thank you for putting the effort in to bring these to us.

Hi thank you for the educated video and detailed explanation

Being able to see what’s happening inside that relay via a laptop graph is pretty wild. I wonder if you busted into that relay could you spot the fault? Reminded me of that old Space Odyssey movie where the astronauts were debating with the computer about a module that the computer said was bad even though they had it in hand and it looked fine. Then the computer tricked the one guy to go out and reinstall it so it could fail. 😂

Great vid love it ❤

Perfect illustration why it’s necessary to properly diagnose a problem.Nice Sherwood CHEERS

Love the video and fully agree with using the scope. In case of relay though I would simply replace it given it costs couple $ ... if you spend 30min of your time diagnosing a relay, it will surely cost more.

Good scope video.thank for sharing

Great video. This shows the power of the scope and it does not lie. Its up to you to look at the data and use fundamentals and experience to make the right call.

Sometimes I carefully use a heat gun to warm a suspected component

Man that was cool how you were able to grab that it dropped out and then came back on that was neat I like it

YOU ARE MY INSPIRATION.

I'm really liking these! Not gonna lie..I'm a newbie at this. My main goal is to help protect my family and friends from parts cannon wielding garages around here. I bought an old versus with a 4ch scope. It's a cool to but old tech.

Great example of using a scope 👍

great job incourages me to use mine more

Do have any autel scanners with scope functions and j box. If you do how do you like it and can you show videos with you using it. If not can you show us some scope work with doing a relative compression test and show us how to set up a trigger to show when a cylinder is firing. What atenuators you would use, amp clamps etc.

Eventually the relay would have failed completely but yes a scope is really cool, i'm thinking about getting a pico scope, only two channels but better than nothing.

The EScope is so awesome 🤤🤤🤤

I had a 2004 chevy pickup with a voltage drop to the trans shift solenoids. It would intermittently cause the trans to stay in 3rd This was a landscapers truck When everything was ok trans shifting voltage drop from battery postive to the fuse that feed the solenoids was 300 to 400mv When it failed after things got hot voltage drop would jump to 3 to 4 volts I isolated the problem to the ignition switch around 300mv across the switch contacts on that power feed to the trans solenoid fuse The new switch was 30 to 40mv across the switch contacts. Heat would build up in the failing switch because of the resistance in the switch contacts and the voltage drop would spike to 3-4 volts and the trans would stay in 3rd gear only Contacts in any load carrying switch or relay with a voltage drop over 200 to 300mv is a failure waiting to happen when you know whats good you can see what is bad

I don’t think the issue is shops not having a scope. Most professional scanners have one built in as well as a Pinout and example of a good waveform. Issue is not very many people left that know how to use them. The industry turned into pull the code check some powers and change part after obd2 became more advanced.

👍👍👍

On my Nissan, power goes to latch thru right door latch.

👏👏👏👏👍👍👍

How you like the zenith? Is it auto auth approved?

Yes It is AutoAuth approved for FCA and NISSAN! :D

If you're a tech in a hurry, you'd most likely toss parts at it until fixed and tell the customer the vehicle needs all of them. I doubt half the certified techs know the process you've outlined.

Sherwood how bout 10 hrs of service no parts just service, if u get done sooner grt

escan

Most likely relay tester would not catch that either.

Gee my 1936 Chev was @ lot easier to work on !!!
