folks see that book on the shelf in the end of the video i'm l1 master car and truck that book is the best money i have ever spend better than a 1/4 inch air racket

@williamtanner8222 6 лет назад

I second that! Well worth the money, as well as the premium channel. I have no schooling, have been on the job for 5yrs, was okay at diagnostics before purchasing the book and subscribing to scannerdanner premium, but within the last few months my knowledge has grown tremendously and I now have ase certified techs asking me electrical/troubleshooting questions pretty much regularly. Not saying I know everything or that I'm the best or anything like that, just trying to give a testimonial that these things are well worth investing into and will help you perfect your craft.

William tanner, you just explained my situation in terms of where im at with my career. I left a diagnostic shop to go to a lazy front end/tire chain store, worst mistake ive done. Im in the middle of making the transition to diagnostics, ive been watching Danners videos for ONE day. I swear i have made more of a connection with electric theory now more than my past 5 years as a tech. Im getting that fkn book. Just, wow. Thanks scanner danner.

@martinsmartinsautobodyandr6740 Год назад

I've been getting many f150 trucks in for no crank no start no comm. Your method of testing for 5 volt reference is priceless. The owner has a few locksmiths and small shops check it out. After consulting with them not 1 person said they checked powers and grounds or for a 5 volt reference. Everyone said it's the pcm. The pcm is talking to several sensors so I ruled that out. Ruled out fuses and relays and ended up finding bad grounds. Many years ago I asked you about a 98 Chevy express van fuel issue and you steered me to the problem. I wish all my friends would stop calling me to beat my brain up with questions but somehow I always fix everything I touch. I'm a collision repair shop but hey money is money there days. It got to where I have to keep my doors locked and my phone off. Lol. I can't thank you enough Paul.

@ScannerDanner 6 лет назад

Thanks for your patience and for staying with me my friends. While I am teaching I cannot produce the same amount of content. I could if I wasn't so picky on how I film and edit things now :-). Watching my early videos is painful. The content has always been good, but the camera work and editing has not. Anyway, this current class runs until the end of May, look for more consistent uploads for June and July. Also, don't forget about ScannerDanner Premium on my website! There are currently around 350 videos with 200 of them recorded lectures from my class at Rosedale tech. The other 150 videos are exclusive case studies with the month of April getting 3 new uploads: 1. "2008 Ford F150 4.2L Waste Spark Ignition, No Spark From One Coil" 2. "2011 Hyundai Sonata 2.4L No Crank Troubleshooting (multiple CAN system faults)" 3. "Honda Power Window Circuit Operation and Testing (multiplex control units and switches)" Last thing, behind the scenes my web developer and I are constantly working to improve the website and in particular ScannerDanner Premium. You guys have been asking for a dated video list like RU-vid uses, and we are working on this as we speak. I've had over 50 new uploads since moving ScannerDanner Premium to the website and some of you are having difficulty locating them once I put them into a playlist. So this new dated list is going to help with this a lot. Thanks again to all of you for helping me make this possible!

Great video man I can’t thank you enough. After putting a transmission in a 05 mazda 3 I picked up for 200.00 I had one flawless day with it and then this happened. For a few days now I’ve been battling with it. Knowing nothing about relays and ground switched circuits I had no idea what it was going to take or if it was even possible to get this car going again. I was able to learn a lot from your video and in a few shorts I had the car running again. Thank you again!

But as many times as I have forgot to switch the confounded test lead back to volt side of multimeter. I could see myself forgetting if it were a jumper wire I was using instead of a test light.

Mr. Danner, I wonder if you truly have an idea of the (global) value of these videos you post. This Mazda 3 for example, is one of those Japanese killers that likely would not have gone to auction in my neck-o'-the-woods but probably to five or six mechanics with the owner cursing each of them (usually behind their backs - but not always!). I can only urge every viewer to support your channels in whatever is affordable to them. You are a God-send - selflessly sharing your knowledge and skills with the rest of us.

Notice what a great arrangement Mr. Danner and garage owner Pete have? The latter appears to have more than enough spanner work on his hands and is happy to pass the auto-electrical along to his friend.

Awesome! I actually understood what the problem was, and why the solution was the answer. Unfortunately, my problem is different. But to be educated is always appreciated. Thank you.

Excellent video. You sir are very good at what you do. I like the fact that you do not forget the basics and that's what the great teachers do, they hammer home the basics. You are very logical and you use a lot of common sense. Common sense is not taught today in our schools. I guess I can't say that because you teach common sense. Thank you for being an exception to the rule, have a great day Professor.
