Hey Paul. Mustangmike here.I just wanted to say thanks for all your hard Professional work i learn a lot off your youtube videos which is were i started. I have been one of your online students since feb.This website is the best i just purchased your book through mail cant wait till it gets here very excited.

Just finished the book and I was not disappointed! I found you about a month ago on you tube and I'm glad I did. between your you tube videos and the book I feel confident tackling projects I never would have before (like my abs light. Found a bad speed sensor using my Rigol scope! not bad for an electrician).
Thanks for all the hard work. I know you do it for more than "the money". Cheers from cape cod.

Excellent work professor. Thank u. I ran into this 2014 lexus es350 the other day with no A/c operation. This compressor had three separate connectors going to it and to get to these connectors is not easy without saying a whole lot of curse words ??. So I checked for a relay and there's is none. Its internal to the box and I couldn't use my uactivate ??. Now the fun part begins ??. Checked for codes in the HVAC module and a code for "flow sensor" circuit high. Now we are getting somewhere. While In there I checked for other inputs such as evap temp, ambient temp and so on. All looked good except the flow sensor sensor pid which read 3.65 volts. Bi directionally I can command the ac to turn on and off. While doing that I was looking at the flow sensor pid while on and no change. Stayed at 3.65. Alldata didn't have info on this sensor nor a good description or operation. I talked to a buddy and he told me that this sensor is internal to the compressor. Some models u can get away with replacing the sensor but not this one. Computer will not send the signal if it sees anything less than 3.7 volts and i had 3.65 all the time.To the computer it means that some type of flow is going on. All in all with the compressor changed out and looking at the pids again..... the flow sensor pid read 4.5 or 4.8 I dont remember , with the compressor not engaged and with it engaged it dropped to 1 volt. Thought I can share my experience with u even though this little piece of information doesnt even compare not even a little with all u shared and taught all of us. U truly are right professor when u say " just with basic principles and fundamentals u can attack any system". You and ur SD premium really changed my life. God bless

hi Danner ma man, your content is second to none m8, in which I have learnt a lot from so that's great, a little pointer on your website to help you out, the layout isn't the best, you need a layout like you did on you tube i.e how you had actual physical sections for each chapter of your teaching were you could click on and view each individual lesson description and content all in front of you and in order without having to search it on your search bar. the search bar is great if you know what you are looking for but if your trying to go from the start of your lessons to the end it can be quite difficult. hope this helps and once again thank you from a mechanic in Scotland

ScannerDanner's reply:
Thanks for the constructive feedback, I am constantly working behind the scenes to improve the site. If you look at the format of Chapters 2 through 8 you will find them to be organized in a way that I believe has good flow. It is complete with descriptions and related videos etc.
I am also adding descriptions to all of the older videos that were moved over in a group from YouTube (about 250 videos). There are many and this is a timely process but we are getting it done with some help from viewers like you!
Also, I do have a dated playlist, maybe you haven't seen it. It is in the drop-down menu of the ScannerDanner Premium tab, it is a "new videos" list. Every video since Nov of 2017 is in this list (when I first moved over from YouTube).

. i just watched that video, same exact arcing and sticking problem. i used a different set of leads and no more problems. in that video you were looking for your 5 volt ref and your leads were shorted internally and giving you a bad reading. your check engine light was back on so you tried to crank the car while still connected to one of the 5 volt ref circuits. and the whole time im watching (knowing that your leads were bad ) im thinking man , hes shorting the 5 volt ref , its never gonna start and then you realized your leads were bad and went on to explain exactly that . "that you were pulling that 5 volt ref all the way down. "
And honestly man , 2 years ago i didnt even know a 5 volt reference existed, now , i understand the concepts and the theory and have the fundamentals to see the problems and issues just as fast as you come across them. i thank YOU for that mr. danner, and im sure that there are countless, countless others who feel the same way . thanks for everything man. we really appreciate it!!
