I'm just an Arduino hobbyist here thanks to the TH-cam algorithm but this was really useful to get a more intuitive handle on pull up and down resistors... And why it may be useful to choose an incandescent bulb when testing my circuits. Thanks! Very useful!! 👍 👍
Hey guy, I have your book and keep it with me when i'm out and about fixing cars. I'm starting to look out for these pull up and down designs when testing. It helps to know and like you said visualize the system. If I get confused about something I'll look at the book and have that ohhhh moment lol. Thank you so much. Now if we could just get all the techs out there to learn this stuff we would be in good shape. My poor Mom just got the shaft from a dealership down south while on vacation. I should of drove down there as soon as she had problems but I am needed at my job pretty heavily and its not easy for me to leave on a dime. Anyways, first trip to the dealer, $1900 for spark plugs, coil, and purge solenoid, and something about a wire at the ebcm needing fixed. Check engine light came back on of course because no one test drove it I'm sure. Now it needs a shift cable they are saying because the PRND321 light is skipping on and off. They have their best tech on it they say. The truck is a 2008 Tahoe and my mom takes care of it. I hate that they charge so much and you don't get what you deserve for your money. I was taught in school, Northwestern Auto, and Eastland Career center, to document what you do and make it legible. All they wrote on the first work order was diagnostic then $1500. lol I've turned this into a book lol i'm sorry guy. Your the best man, keep on teaching these guys the right way to do things and hopefully we get some good techs out there.
Circuit high pull it low to check integrity circuit low pulling high and wiring is most likely good back to computer still gotta buy a probe kit ❤thank you
Great video Paul great teacher.Oh by the way those videos you did on your Jeep was in my opinion was on spot real life in the field with what tools you have and also on your Motor Home. May you and your family be blessed.
Paul, I wish more people would watch these types of videos before they go searching for their own issues with their vehicles. If people saw and understood what exactly goes into a quality diag, I know mechanics would financially benefit! People need to understand just how freakin complicated this all is!! I think most people think working on cars is easy, and shouldn’t 1. Take that long to fix, and 2. Shouldn’t cost that much either! Thank you again for taking the time to post these videos!!
Paul my name is Steve Miller and I just came across you videos in the last few weeks. I have a 1997 GMC Top Kick 366 gas engine that is having problems. I’ve had it to 4 different shops and no one has been able to fix it and no one has been able to read any codes from the ECM. I have changed out every sensor and everything else there is to change. Spark plugs and wires, distributor, coil, injectors, fuel pump, oxygen sensor, muffler, intake gasket, map sensor, and everything else I could think of except for the fuel pressure regulator. The grounds were cleaned, all fuses checked and they put some kind of electrical grease on them. The problem I’m having is when I start the truck it will barely run. It spits and sputters and backfires some. Finally it idles around 1250 rpm for at least 5 minutes. Then it slowly idles down to around 8000 rpm. At this time I can drive it and it runs pretty good but if I stop it and let it set for any length of time it goes right back to spitting and sputtering won’t hardly run till it warms up again. Do you have any suggestions on what I can do? Thanks, Steve Miller
It's on my website my friend. I think this was Part 4 of a 6 part series on pull-up and pull-down circuitry. Hope to see you there! www.scannerdanner.com/join-scannerdanner-premium.html
So I'm used to working on Cat diesel equipment but trying to learn more automotive stuff for personal repairs. Signal voltage on the stuff I'm usually work on is 5 volts, what is the usual signal voltage on most automotive stuff or does it vary by manufacturer?
So with the crank sensor not being enough is that just because the reluctor wheel doesn’t have a bigger notch than the other windows because Ik a 3.0 ford Taurus can run without the cam single
That is because that engine uses a waste spark ignition system, so it doesn't need to know where #1 is exactly. It only need to k ow which pair of cylinders is approaching TDC and the sync notch in the crank provides that
Does anyone know if SD’s book is newbie friendly? I’d like to get into the automotive industry , and it was suggested I study SD’s work. Anyone recommend this?
My suggestion is to buy the eBook and if it's not right for you, I will refund it! I also suggest that you sign up for SD Premium where I am teaching page for page from the book (this video is an example of that). If you really want to learn this field, I can definitely help get you started and in a huge way. Hope to see you there!
Thank you Mr Danner I'll be here for all sessions
Thank you!
Thanks for teaching us Scanner Danner 🙏 God bless you and your family

Thank you Pablo!

Thank you Brian! I agree 100%
With all due respect, they don't know about Professor Danner's work or they would Sir.
Very classy teachings Paul...thanks for making this available
Thanks John
AWESOME, THANKS FOR SHARING SD😍
LOVE THESE LECTURES😍
STAY BLESSED GUY'S❤👍👍👍

I dont know what a GMC Top Kick 366 engine is?? What year, make, model and engine size in liters please
Waiting for part 2😊

Awesome lecture. Thanks
Thanks for the download
grazie ❤
Paul, great video and info!!!!! I think the radiator cap is bad !!!!!!!!!!!
Thanks Danner, your book is also very helpful, just want to know is the other name of 'pull down' is negative switching.
Thanks.
No, we apply those terms to output circuits (chapter 3) not inputs. Thanks!
So I'm used to working on Cat diesel equipment but trying to learn more automotive stuff for personal repairs. Signal voltage on the stuff I'm usually work on is 5 volts, what is the usual signal voltage on most automotive stuff or does it vary by manufacturer?
5v is a standard that extends way beyond the auto or diesel fields.
Perfect...!!!
So with the crank sensor not being enough is that just because the reluctor wheel doesn’t have a bigger notch than the other windows because Ik a 3.0 ford Taurus can run without the cam single
The 1999 to be exact
That is because that engine uses a waste spark ignition system, so it doesn't need to know where #1 is exactly. It only need to k ow which pair of cylinders is approaching TDC and the sync notch in the crank provides that
@@ScannerDanner oohhh ok thank you 😊
