I appreciated the Christmas story. I agree with the one fella from the continent of Africa, in that your diction and eloquence make the videos stand out. The first video of yours that I viewed caught my attention because of the wit you showcase when working on the 'Whiteboard of Knowledge'. You were probably talking fuel trims. Anyway, it had a different feel, and seemed set apart because there was a pedagogy component that not many can do easily. Cheers, Schrodinger! You deserve the success.

Merry Christmas! I was touched by the story at the end! I always learn something when I rewatch one of your videos. By doing many things that you taught me, I mostly remember it, but sometimes something important is missing. I'm sure when I first watched those videos I didn't pull out as many nuggets of truth as was possible, but with knowing more, I get the light bulb moments so much easier. I guess I'm in the camp where I don't need the deeper how to anymore, but to anyone thinking about paying for content with you, I did for a long period when I needed the help more! :) (and it's so worth it!)

Hey Matt merry Christmas. A few days ago I watched both of your videos on fuel trims, and it was very informative and I made a diagnosis on a 2007 e63 amg. I was getting lean codes for both banks.. maf sensors were dirty, I cleaned them and it helped a bit however I have to get new ones. My LTFT on bank 1 was 39.3% and bank 2 was 57%...im not kidding... STFT was staying around zero, both banks of o2 sensors were at 0.45v. Cleaning them brought both banks of LTFT down to 21%..I unplugged both mafs, unfortunately the vehicle has 2 of them which doesn't make it cheap.. And LTFT and STFT went back to zero.

Where is the fly back diode located? I would guess that what you've been calling "pnp" transitor is actually an MOSFET transitor. One of the neat additions to an MOSFET device is you can sense the current flow through the main device. This would be what you're calling "REF LO". And actually the structure of the MOSFET device has an intrinsic diode which would work as the fly back diode. en.m.wikipedia.org/wiki/Flyback_diode

[@SchrodingersBox]

Its absolutely worth buying. It's still as viable a tool as when I got it several years ago. Absolutely.

[@justdata3650]

Your tutorials are excellent. I haven't seen your electrical series yet so if I'm duplicating an idea here then sorry. However, I would in addition to what people are learning from you suggest anyone who wants to really understand this to do a basic course in electronics (not electrical, must be electronics). Once you learn about resistors, capacitors, inductors (coils), diodes, and transistors (I hope I didn't miss anything - it's been a while) and how they are used in and react to both A.C. and D.C. and ohms law (there's tons of free ohms law calculators on line) so you have an understanding of the basic building blocks of all electronics -- that grounding makes everything so much easier. I say this as someone who started a career as an analog and digital design engineer so I say this from a point of knowledge although these days I don't remember much more than those basics having moved to computer software more than a couple of decades ago. To give an idea of how powerful these basics are consider this... put a couple of transistors together and you get a latch. Put latches together and you get basic logic gates (and, or, xor, not). The most complicated parts of your computers are just millions of logic gates so from understanding a transistor you have the grounding to be well on your way to understanding the most complicated machines in the world. Obviously that's a bit of an over simplification to make a point but it's not as far off from reality as you might think.

[@SchrodingersBox]

Duly noted. The series is basics in electrical first because I believe that’s first before learning electronics. For example, you have to understand power and ground side switching to understand a transistor’s function. But the second reason is I myself am still learning electronics so I need more familiarity myself before I can make electronics videos. But I will!! Great point and I agree with your idea.

[@justdata3650]

@@SchrodingersBox Thanks for the nice comment and I could image your videos on electronics being exceptionally easy for people to follow given how clear you are in your communication. Or to put it another way, even though so many people have said it before, your videos are awesome! If this last diagnostic I'm trying doesn't work (I'm getting a smoke machine) for this long standing fuel problem I have I will be on your other channel sooner rather than later in the hope that a few more brains can help me track down the source of my problem with my E36 BMW. If you are curious, the short version is that it has a leak so slow I haven't been able to detect it (using die and many other tests). Slow as in it takes 10-12 hours before it's lost enough fuel pressure to cause me to have to turn the key several times to build up pressure so that it will start. I ignored it for a long time hoping it would get worse so it was easy to spot but no such luck... I need to stop otherwise I'm going to go down a rabbit hole of everything I have tried to find this thing.

[@DallasAutoDiag]

Great video as usual. One thing though, I don't think we can realize the difference between the common ground and common lo ref by only function. We have to look at colored wiring diagram. Unless future lo ref separate video can show us a way to do so with a dvom or a scope. Thanks again for the free video and definitely going to be a paid member soon.

Would it be possible for you share some technical videos for my understanding. Thanks for your kind consideration.

[@JD-526]

An explanation I have been looking for. I noticed the test light you are using from another video of yours, you explained that it can be used to test without hurting electronics, if this videos test light is the same. How and where can I find this test light? Also what is the proper name in case I have to search this out, is there a link you can provide. Now when I had a bad coil I used my scanners oscilloscope and using the ground going to the block and my amp clamp I could see all the coils fireing at the same time I noticed one of my coils had a different waveform, (7 Apple's 1 banana) but without knowing the fireing order and it didn't matter I used my secondary ignition pickup adapter on channel 2 of my oscilloscope and moved the clamp to each spark plug wire checking the oscilloscope until both waveforms lined up on the oscilloscope, found the bad coil. Another way you can do this to is just unplug each coil until you don't hear a difference in the engines fireing. But this method does not work on all cars. Oh if you get a Subaru plug wire you can test coil over plug applications out of head. Thanks for taking the time out to make these informative videos. You by far explain diagnostics step by step better than engine else I have found on KZbin. Keep up the good work.

[@SchrodingersBox]

any LED testlight is safe.

[@Fee.1]

One last question. For someone who is capable of getting to this level but may need far more than you’re offering. Where would you advise we start?

[@SchrodingersBox]

Thanks for all the previous questions. To answer them all in one swoop: My suggestion- and this is sincerely, not biased- you are a prime candidate for the pay channel. You don't need technical cert or even background. The basic electrical series will take ANYONE with no electrical background and make them able to do the stuff I did in this video with full understanding. I am told ALL THE TIME that my videos on that channel are better than the training most students say they get at their automotive schools. In fact, some automotive schools have used the videos in their class as part of the curriculum. ALso- I did not check on the cat so according to schrodinger's theorum it is 50% alive and 50% dead at this time.

[@Fee.1]

Schrodingers Box thanks I thought that may be the case but wanted to get your thoughts on it. Random question. Are you by any chance as well versed on inrush current as you are with these other topics. I’ve spoken to engineers at Fluke, Klein, Southwire, Uei, and Agilent. And somehow I wind up stumping all of them and I’m just asking a few questions

[@georgemccumber7024]

I got a wire off the breaker on a fuse box to go to the fuse box to the Honor by the transmission and I don't know where it goes can you tell me exactly where it goes thank you

[@SchrodingersBox]

pretty simple- check to see if the wire is a feed to the fuse or a return after the fuse by checking the voltage. If it’s a feed to the fuse box simply identify the missing power side of the fuse that the wire came from and that’s where to connect it. Easy!

Usually REF LO is for the purpose of supplying the computer with a reference ground voltage from a place where that voltage is different (or varies) from the battery grounds being supplied to the computer. It is POSSIBLE they could measure something on the ref lo, but more likely they are measuring something else (for example the IGN CTR SIG) in reference to REF LO. This REF LO voltage is different from battery ground because of the high currents flowing through the coils and the slight resistance of the engine block and battery cable going to the battery ground. It's also possible that it's needed only to fire the transistor and no measuring takes place. Misfire is usually measured from crank position sensor RPM variation. That's my theory anyway.

[@SchrodingersBox]

Makes total sense to me. I agree- there has to be some difference to measure that there is activity (voltage or current) that takes place from the secondary. All I know is the secondary ignition event sends current to the Ref Lo. I do not know if there is voltage or not, I presume there is, in which case there must be some type of load on it,

hey Matt, I came across another four wire system on scanner danner which did not utilize the feedback wire and initially confused danner himself. This wire was actually connected to one end of the secondary coil and also went to block ground. Normally, one end of the secondary is tied into the positive feed of the coil and the other connects to the plug wire. Therefore on this particular car there were two wires connected to block ground. This type of coil, as was later discovered was built like a proper transformer as are the waste spark type of coils. The car was a volkswagen passat. Are you aware of this system and ever come across it yourself ?

Merry christmas, I ran into a dodge charger v6 with spark ionization codes, 4 wire coils, clear the codes and it ran perfectly fine but when the code would set, dead misfire on cylinder 6 couldn't figure out the problem .-. The car had a new coil and 6 new spark plugs the customer replaced.

[@SchrodingersBox]

Anytime I have a misfire (or no start) I think “FASTTEC”- Basically fuel, air, spark, timing, exhaust, compression. It WILL be one of those (or combination). On a single cylinder misfire you can rule out timing. But it’s going to be one of the others. Check of there is spark and fuel first then try compression.

Need to find that teacher w/the method that matches my brain signals. I was stuck in algebra for 3 years till I found that perfect teacher for me. I’ll definitely pivot to ur paid classes & hopefully my brain starts to accept the plethora of money saving info and perhaps even another stream of income! 💵 👩‍🔧💵 I like your questions and pauses during the videos. 🤔🧠 MERRY CHRISTMAS 🎄🎁 🍎 TEACH!

I checked the obd port and I have power ground and signals I have 120 OMS. I been checking all grounds and powers and and if I disconnected any module and recheck obd port for OMS again I get zero put new computer in it and still nothing. I'm not an electrician person I start watching your videos and I thought that you can give me some help security light is not on the only thing in dashboard is traction control and stabilitytrack and is not showing in which gear is it is not cranking and fuel gauge is not working I have fuel pressure starter works and last thing I have signal on every sensor

Happy Christmas a diffent chrismas already My only need right now is related to Turbo Desiel systems I have a Motorhome based on a Fiat Ducato RV Dodge Ram and just seen this on a Forum and i thought of you! Hi, Guys I have a problem with a Ducato 2.3 on a 07 plate the engine will just cut out at different speeds randomly. The engine light comes on but if I'm moving and dip the clutch turn off and then on the thing runs fine for a while. It's not every day though, and at 70, 30, OR JUST PULLING AWAY. I HAVE HAD 5 DIFFERENT Dienostic Boards ON different things changed witch I have changed as recommended from diagnostics 1 cam sensor so changed that 2 map sensor 3 mass flow 4 turbo boost sensor 5 fuel rail sensor 6 fuel filter complete with housing 7 THROTTLE BODY UPGRADE 8 FILTERS IM GETTING TO THE POINT WERE IM GIVING UP any help I would very thank full Have you come down off the ceiling yet?

[@SchrodingersBox]

I would have to see what data you are using to interpret these parts changes. You mentioned they were changed as "recommended from diagnostics" but no data was shown on what the diagnostics where, For example to change the MAP- the only possible way diagnostics would recommend to change it wouyld be if you show incorrect MAP voltage after confirming reference, signal and ground-what were those measurements? So its confusing that all those parts were "recommended by diagnostics". Need to see the diagnostics data.

[@eleanorrigby3038]

@@SchrodingersBox Wasn't my problem just your classic parts changer, had a plethora of codes and just changed everything. His problem was likely to be related a known Ducato problem "rusty junction", corrosion due to a poor design of the windscreen scuttle, rain is directed to an area under the fuse box that can also kill gearboxes by filling with water. Thankfully sorted since 2014 my question fell off the end post too long?

[@SchrodingersBox]

Ah well if it was just parts cannon firing I can’t help with that. I at the very minimum just need some basic. foundational level data like fuel trim curved against load with induction metrics on the MAP and MAF. Just some basic starting data to get a direction. Right now there is nothing for me to go on.

I never pay for any content as there is plenty of free offerings. The videos are appreciated, but none of this is rocket science, so people can learn it on their own, if they really want to. The future of information and knowledge is FREE.

[@The_Noticer.]

I have never found this to be the case, to be honest. If someone has already put in the effort to gather all the useful information and ordered it in a digestible fashion, why waste time going through the whole process yourself. I don't know how much you get paid by your employer, but I don't think as little as $3.49/hour. Work 10-15 minutes overtime for the amount and spend all the hours/weeks/months you would have investigating it yourself into something else. Like... helping family/friends/needy fix their cars when partscannon shops rip them off. There is a saying, if you're not paying for it, you are the product.

[@pl5882]

Shekelstein Agreed. Plus the $ in parts you save alone is worth the pay channel. Matt has put in his effort so you can learn this stuff in minutes, not days or years even. If you want free stuff vote for the other guy- I mean go to Scotty’s channel.

[@randirlom9508]

True to a degree, but there is value in paying for the convenience in having the information from one source and not having to sift through some of the trash info out there. Matt is great in that he assumes no prior knowledge and explains in layman terms as opposed to someone like Scanner Danner who targets a more traditional training environment. Both are worth the money spent on their pay channels depending on one's preference.

[@SchrodingersBox]

I see your point Pepe but I agree way more with the other comments and NOT because I am biased. The whole reason I created this channel is because of the overwhelming plethora of nonsense BS crap that inundates the very very few videos that are useful and accurate. By creating a safe-haven from the 99.999999% iof "parts cannon" channels I think there is a pecuniary value- and it's proven.

[@GalaxyOneFilms]

Ok first of all it's not enough to just smell the spark plug. You must inspect it, observe it, and most importantly listen to it. The plug is trying to speak to you and the only way to hear its song of sorrow is to become truly one with the spark plug. You must let it flow through you as easily as water flows through a stream. Only then will you be able to diagnose the vehicle with a faulty fuel injector.

[@SchrodingersBox]

Hahahaha. Pretty much nailed it lol!!! The story about those giuys beiung the ones in line at Autozone is true too, isn't it?
