This is one of those times when I can't find words of appreciation to say. I only hope you know how helpful you are. I thank God for giving us a great teacher as yourself. This is coming from Lusaka, Zambia🇿🇲.

[@jsims2985]

That's beautifully said, man. Best of luck in life, brother.

I remember asking why wouldn't you go out and make a boat load of money with your abilities. You said your path is to teach and your teaching goes world wide and helps so many who need this information.

Your passion for teaching is evident in every video, and it has had a significant impact on my learning journey

[@ScannerDanner]

So awesome to hear, thank you!

[@Joserocha-wm9de]

This is what makes YT the best source of knowledge in 🌎 ( ya we know internet also has it's bad side ) but SD videos are a gold mine 👌 Sorry for your friend's loss 😢

[@spelunkerd]

The cool thing about those classic four pin relays is the way they fit into their home two different ways, upside down or right side up. The clever design allows them to work perfectly fine, either way. Those four pin relays are protected from accidental wrong insertion by always having the load side power diagonally across from the load side ground, and the same for the control pair. So, you can safely assume that a four pin rectangular relay will have diagonally opposing partners, although you don't know which is which. In those specific relays, that makes it impossible to accidentally jump load power to computer ground if you avoid any jumping that is not diagonal. And it makes tools like your AES tool work fine across many different platforms.

Great video and explanation on how the starter system works. I wish AES Wave would re-introduce that tool. I know they are supposedly revising it but it's been several years since it has been available for sale. RIP Flipp.

This way they can get you to buy a $3,000 bi-directional tool to turn it off and on.

Hi there sir I had a ground issue I fixed it then since then it’s been almost 6 months I am Watching your professional diagnostic Perfec videos I took a huge risk on my cadilac Escalade esv v8 very huge step to learn because of you I 80% I can diagnose any car without a scanner your the best god bless you

[@tomclark3592]

One hell of a great teacher. Great video as alway's!

[@carmo9693]

So watching this video brings back memories for me being in class at Toyota and Mercedes Benz there are few teachers that can bring it down to an easy understanding as you do from the stand point of being a newbie and so young. There was 1 in Toyota and 2 in Mercedes that had that ability. Being taught by my shop foreman at Toyota he gave me the insight and ability to ask the questions in class to get things started, there were times that the class was for better words not going anywhere and I would ask the teacher a question i already knew the answer to because I fixed at the dealership already and they had to research for the answer calling sometimes the engineers to find the fix. Hey if you are teaching you should know how to come up with the conclusions I did sometimes spending hours to trace it out pulling interiors apart to find said bad crimp connection. These were on brand newish cars too. Later on they would find a DTB for said problem back in the day when computers were not used as they are today. Retired and love watching your videos and I can say some of the things you teach gave me better ways to diag then before, you put a different spin on it and we look at the problems differently and come to the conclusion and fix. Rest in peace Flip many of my friends to are doing the wrench turning in the afterlife or just looking down at us laughing from a better place.

[@spelunkerd]

Another excellent teaching video. I'm glad you expounded on the need to do final testing on the starter itself, even though your testing up top pointed to the starter motor. The work flow of professional shops is to make the diagnosis, get approval, order parts, and a few days later get it all done with parts in hand. The tech who does the work may not even be the guy who made the diagnosis, and they could easily lean into it and do what was planned with no final testing at all. Disappointingly, we see that here on KZbin as well.

Awesome video. I haven't used the 12v incandescent tester, but I get an audible clicking when the ignition is turned to start with the panel lights flickering. No corrosion on studs/nuts/eyelit. Did the screwdriver trick and heard a "whirl" each time where I'm thinking it is the clutch that gave out. No crank each time, however watching this video I think I needed ignition key to be on run while I did that?

I need some advice or information if possible. Could you tell me how to direct wire crankshaft sensor to the computer? 98 blazer 4.3. I need to bypass temporarily.

[@PROUDAMERICANFORLIFE]

That's a fancy way I'd just swap the starter relay for the one that sits Wright next to the one your working on the one I seen on the left is the relay for the 4 ways if u look both relays are exactly the same so if u switch them it starts or the the 4 ways don't work after u switch them then it's a bad relay always check your fuse boxes for relays like the one in question most manufacturers youse the same throughput the vehicle its 50/50 if u find one you don't need to do anything elts just get a new one and it's fixed nice video 😉

[@ScannerDanner]

And when you swap the relay and nothing changes, then what?

[@rudyromero552]

Buen hombre agui surely.

[@happywrenching960]

My pcm ground is intermittently, not getting to my Starter relay. What do I check for that?Update: I checked the wire from computer to starter relay. It has good continuity. It just isn't sending the pcm ground to the relay. It starts and runs fine when I jump the 12 volts to the starter. Any thoughts?

I’m not in your classes, but when you are asking the questions to the students, here’s me feeling under pressure to answer correctly and not let you down.

[@ScannerDanner]

Such a great comment, thank you for this. God bless you

[@kerryb2689]

I recently had a 73 ford truck that would not crank, but the headlights did not dim. Checked (attempted) cranking voltage with a voltmeter and was less than 10v.on the battery terminals - not enough to engage the solenoid. I suspect a shorted cell inside the Optima battery which is a potentially dangerous situation. Battery voltage was 12.3v with no load.

[@ralfsautomotive]

Paul, the U-Activate is nice but has to many adaptors missing there are better and cheaper options one of them is a rental tool at most auto parts stores.

[@duanedonaldson2262]

HEY SD, Paul, for the scan tools that you use and if they show the total number of modules once the full scan is complete, can you please show this in all future videos. In this case, at timestamp 0:40, there are 12 modules listed at the top of the scan tool shot, this way if we have this vehicle with less than 12, we can figure out what is missing as not all scan tools show a module that has no comm and we don't memorize these bits of info but a few of us do take notes of many YT videos. I also have noticed that YT is showing these CHAPTERS just above this comment section, it seems that you, the content provider are giving the timestamps so that is you or your son taking even more of your time to improve on your processes. Thanks for this special dedication video to a student and friend of yours.

[@ScannerDanner]

That's me at the end, when I review my sons edits. I add the timestamps which makes the chapters in the video player. Thanks for noticing!

[@patrickkyker]

What about rotating the engine manually to make sure it's not hydrolocked? Or do you think there would be external signs of damage for something like that?

[@ScannerDanner]

Yes sir, in that case it would have been a heavy clunk of the starter as it tries to rotate the frozen engine. We would have also had light dimming in our first test. Make sense?

I am from Iran with pride and with hot internet and many problems, I don't know if you are aware of it or not... I have a question for you. Because of the sanctions, we cannot have the wiring diagram of the cars, any car from Toyota, Hyundai to Dodge, Cadillac, etc. I do it like the cars of 50 years ago without a map, that is, I look at the color of the wire and open the adhesive tape and take the wire trace.

@scannerdanner man can you please help me with my 2000 sls Seville, no crank at all, I had disconnected the positive cable from the batt overnight and next morning when I re connected it it didn't respond at all to cranking the key , I checked starter it's good , brand new battery , and also I can get it to start by manually bypassing the starter relay but 3 seconds after it fires up it cuts engine power. And when I first connect the cables back to battery, with key turned to on, the security light doesn't illuminate. It doesn't light up even after trying to bypass starter relay and the engine cuts itself off, it only illuminates and stays on after I attempt to crank the car from the inside with the key. . Please help me any advice is appreciated
