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!

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.

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!

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 !!!

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

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

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.

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

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.

Loving the Scope series!!!

Love your videos. Learning a lot.

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

Excellent demonstration.

Great video as always.

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

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

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.

Good scope video.thank for sharing

Great vid love it ❤

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.

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

Hi thank you for the educated video and detailed explanation

YOU ARE MY INSPIRATION.

Great example of using a scope 👍

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.

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.

The EScope is so awesome 🤤🤤🤤

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.

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

👍👍👍

👏👏👏👏👍👍👍

93k getting there

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

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

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.

Most likely relay tester would not catch that either.

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

escan

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