First!!! Merry Christmas Everyone!!!
Im from Sudamérica could i see all the videos ?
Hi from Odessa Ukraine. Merry Christmas and happy New year. I hope for many new videos in 2020. Thanks.
Hi I'm from Algeria, thanks a lot for the valuable videos you're providing for us. Keep going.
So sorry Mr Matt, I was in California over Christmas and forgot to wish you and your girlfriend a Merry Christmas
The ref. low in gm cars is another ground. You can disconnect the main ground wire to the block and the engine will use the ref. low as a ground to run the car engine. Bill Starsiak DDS Oral& Maxillofacial Surgeon Merry Christmas I enjoy your videos
I think Scotty is right about the field of automotive electronics opening up like never before. Thank you for your time and effort, and I hope you have a wonderful new year.
I watch alot of different techs..and this guy is by far the best instructor...
Merry Christmas. From a Chilean guy living in New Jersey and kicking ass with solid diags thanks to guys like you. All the best sir.
I love this guy, he's very intelligent and brilliant. More wisdom and understanding
I’m a professional technician from 🇬🇧 & fully understand the ignition circuit designs but I still love watching your channel & how you go about diagnosing. I can tell you from over 30 years of experience I learn something new everyday & never give up my thirst for more knowledge or ways to improve you can learn new techniques from both amateurs & professionals including learning from their mistakes so keep up the good work both paid & free channels.
Merry Christmas & happy holidays
Madds 🎅🏻
Thanks man! Not sure I've seen you comment before so I appreciate you stepping up and being known! Thanks for the feedback!
Go ahead and message him for free access from a developing nation. :P I joke I joke I kid I kid
Simply outstanding! Thank you for your service.
Merry Christmas Matt, thanks for everything you do.
Thanks Adam, thanks for your support.
Merry Christmas Matt!!! Great video with much detail, thanks.
Thanks Jake for the many years of support!
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!)
Thanks David- much appreciation for your what now-- 7 years of support now?
@@SchrodingersBox I can't be certain, but yes. That sounds about right. Lol. I thought about all sorts of memories thinking about that. From the age of my kids, to where I lived to someone of your unforgettable diagnosis and understanding videos. Heartfelt Christmas specials and cat poop of course! Lol
Found a great channel, so much useful knowledge! 👍❤️
Merry Christmas Matt!
And Merry Christmas to all of your viewers as well!
Recent subscriber, in 2 videos I was able to disgnose and repair 2 vehicles with wire problems that have sitting dead for months. Thanks, will be signing up for pau content soon as x-mass shopping season is over. Your awsome.
Thank you!!! Merry Xmas my friend!!
Marry Christmas and happy hollidays!Man you have good ❤,you got me with that free access for some people.👊
Merry Christmas and have a great new year from this beginner. Great videos that Ive seen so far.
Thanks and good luck in your journey into being a skilled diagnostics!!
I commented "am excite" on your paid announcement vid, still haven't got it, still plan to, I could afford it right now, it's just now worth the cuts I'd have to make, but in about a year things should clear up and I'll be glad to give you my money. Thank you very much for making your educational content accessible to those who really need it, as well as creating it in the first place; I'm sure it means a lot to the people it helps.
Thank you for your time and effort
This is really goog present for Christmas Thanks Maat I hope your enjoy today with your family.
Thanks Pablo!! Always great to hear from you!
I like watching your free RUclips videos. I understand the paid site is cheap, I don't have a good excuse. Haha. However, I am a full time 13 year in the field heavy equipment technician. Funny thing is, I do not really understand ignition systems other than the fact they throw spark. I find value in all of your videos anyhow. Plus, I love your straight forward attitude and your scientific breakdown of the systems and diagnosing. Thank you! Merry Christmas!
yes... thank you for the special gift. i learned from your channel .
The best gift there is!!
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.
I was burned hard by these recently. Had a Volvo come in with a single cylinder miss. Misfire under load so I brought out the scope and checked the current ramps on the single feed wire for all the coils with a 2nd channel on a random control wire. They all looked the exact same, good amps, everything, every cylinder was there. Looked like an idiot when I told my boss it can't be a coil. I've studied this a few years ago and thought I understood it until I came across it in the field. The funny thing about 3-4 wire coils is they're usually easier to get to, so I just end up swapping coils or using a test light. Job done in 5-10 minutes. This time I wanted to just use the scope only and it backfired on me, I forgot what I learned and honestly didn't know a good current ramp can still be a bad secondary on the coil itself. I turned a quick diag into a 3-4 hour ordeal over nothing.
The best part is my boss is 65 and can't reliably diagnose a 2 wire bulb circuit and he "diagnosed" it right away based off symptoms as a coil. I brushed him off because he's never right and he wasn't really right in this case because that's not how you diagnose anyway. I knew it was most likely a coil, so what? It wasn't until I tested it that I got burned.
Mistakes are the best teacher.
love this guy
Merry Christmas. Thank you so much Christmas present 🎁 I am from Mongolia.
I love watching your channel, very informative, you’re a clever guy, keep making videos, also love your responses to the trolls😂👍
Happy Christmas from Ireland 🇮🇪.....
Funny, Ireland is one of the more populous of my non-US viewer based countries!! Must be the whiskey lol!!!
Happy Christmas from Germany...🎅👍
Germany!! On my bucket list to visit for sure!!
I like that guy from that small village somewhere in Africa, I understand him exerting effort for honest survival for the family by enriching his knowledge for his trade. I share and feel his cravings. I know how difficult it is however you want to search the RUclips if you are in a difficult situation. Back in the Philippines when I was there I being jobless, I can not surf the Internet. It is costly.
Thanks buddy..Excellent explanation
Always welcome
Hey Matt, Merry Christmas from Canada. Happy New Year too
Thank you! Happy New Year bro!!
Hi ! Great channel, I don't understand English exactly, but I still learn a lot from you. Thank you and Greetings from Poland.
Thanks. I wish I could transcribe one polish so it would be easier!
@@SchrodingersBox However, I prefer English, it's not easy but by the way I'm also learning a language (and most importantly, technical English). Thanks !
Have a great Christmas
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. Have a fantastik (intended) week off, and a great new year. Great video, as per the usual!
Thanks for the sophisticated comment! love your screen name too lol
@@SchrodingersBox - Always. Jah bless! Love and light to you, your family and friends this new year.

So I'm a former parts changer you like to call out. After I finish watching all you have on youtube, I'll join the website you mention. Thanks for posting these videos.
Pretty cool of you to admit. Thanks for the comment, glad you are in the light now!
Thank you for your videos very good content
Thanks as always!!
U r a class act.
Very good mate in wot you do thanks mat 👍
I lost hope that I would ever know how internals and wiring of spark plug coil works until I saw this video of yours. I even failed to understand it in Paul Danner's videos.
So this is basically the best ignition system educational video I have seen in youtube.
I am specializing in Diesels. Gas motours are not popular in my third world* country 😂😂
Thank you for these great videos.
what a great compliment, thank you!!
if you are in a third world nation you should send me an email and see if you qualify for access to my paid content channel.
Merry Christmas Matt
Thanks Phil!!!
All I can say is that YOU are the BEST!!!
Am in ZAMBIA southern Africa, since coming across your videos I learned a lot, thanks my brilliant tutor, God bless you. I will be very very grateful if you give me access to your SBQM..
happy to help. send me a PM with your email address and I’ll set you up.
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.
Thanks for the video Mat 👍👍👍👍👍👍👍👍👍👍👍👋👋and God bless you🙏🙏🙏🙏🙏✌✌✌✌✌
Thanks for watching!
happy new year
To you as well! Thank you!
Merry Christmas everyone
First and foremost I would like to wish you happy merry christmas.
I am from India, trying to learn more automotive basics especially automotive electrical system and saying thanks is not enough, for you guys helping us lot to understand automotive concepts.
Would it be possible for you share some technical videos for my understanding.
Thanks for your kind consideration.
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.
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.
@@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.
I got out of automotive back in ‘97. I still work on my own vehicles and that it. No I don’t work on other people’s vehicles anymore. Thank god.
Merry Christmas Matt for IRELAND! 🇮🇪 (Yes, another one 👍😂😂)
hahaha yeah I always remember the ones from Ireland because they always ask me for diesel videos lol!!
That’s the country folk lol I’m a city gal. All my cars are petrol! 👍😂😂🤣
What a wonderful Christmas story, Matt!
You've changed my approach to diagnosing over the past few years. Now I'm proud to say that I'm no longer a "parts cannon" type of guy! (lighting those fuses gets to be expensive!)
Again, thank you for sharing your knowledge in an easy well explained format.
Merry Christmas!!!!
Thank you!! Will have more content for you soon!!
Merry Christmas, Matt! Love you, bud (no homo)!
Aw too bad.
Did you just have to bring up sodomy for no apparent reason
@@kennykrylov4513 Hahahaha, there is always reason!!!
Hi Matt,I am very interested in your channel more so in automotive electrical, I need to be a wizard in this area from Kenya
Send me your email address and we will see if you qualify for free subscription to my Quantum Mekanix website
11:38 I can literally feel my brain switch from listening to _in one ear out the other._ 😔 Been trying to learn electronic concepts for years but the olé brain shorts out. 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! Thanks 🙏🏿
If my paid classes don't let you finally understand electricity, let me know and I'll refund your purchase- how's that for a guarantee?
Schrodingers Box Sir that is some old school honor and real pride in what you do! Wow so dope!
I am a subscriber to the QM channel. But I am from TN does that qualify as a developing country? Seriously enjoy your vids and became a subscriber to the QM channel when it first came out. Just now found you again.
Is there another video on the followup of the Jeep Grand Cherokee that got the 3 year parts and labor warranty on the fuel pump? Was just curious to see how it held up. Thanks for your time.
There is indeed! Not sure the title but search jeep cherokee on my channel search.
The video is good, the content is good, the English is good, but the drawings... LOL! Merry Christmas!
true that hahaha omg its so amazing i ever got past 10 subs being unable to even draw a straight line
Have you ever checked out a Uni-T 181A type of multimeter with the graphing “baby scope” style functions ? Any opinions on the value ?
Bernie !!! Ms Vikki. And yhe Kat. 🙂
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
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.
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.
Hey Matt and a belated Merry Christmas to you and your family from Brazil. You did a great job with the explanation of the ignition system. I sent you an email through gmail and hopefully you got it. Have a great New Year!
Oh wow have fun in Brazil!! I’ll check the mail. Btw, pretty dramatic change since 4 years ago eh? Thanks brother!!
Merry Christmas & Happy New Year.
I've been watching alot of your videos, to try and find out what happened to my 01 Prizm.
I was driving along yesterday, in slush and snow and had everything on (lights, rear defroster, wipers, heater, etc.)
When the battery light came on and the engine died.
Turned everything off and tried to start, but just cranking.
Is there something electrical I should check first or should I start F. A. S. T. T. E. C. 🤔
Always start with FASTTEC!
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
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!
I think my car has 2 challenges for you that have blown my mind since ive owned it. I don't want to go all crazy changing parts but I cant figure out how or why my car acts the way it does, I know for sure you would be able to find the issue. I definitely enjoy all of your video and I wish I had the time to perform these test on my own for fun. Man in what state do you live?
Colorado. Give me some data (not symptoms- just data) maybe I can help.
@@SchrodingersBox I havent collected any data to be honest becuase I dont even know where to start. There is no CEL and I have no OBD2 scanner but I'm going to buy the 'bluedriver' soon. Idk if there can be something left on the memory of the PCM that will give a hint as to what I can be, I have 2014 Chevy impala 2.5L ecotec it has 90k miles on it, I have a sound system in it, majority of the time when I'm at a red light with the music turned up all the way the car acts like if it wants to turn off, it starts to studder and does kinda of like jerking forward motion it's very annoying. All though I notice this very little with the radio turned down. Has happened every since I can remember, I saw your video where you found coolant in the cylinder bore and did smoke test and all that and I felt like that could be it but I'm not like that, I dont change stuff just cause I feel like it will fix it. I want to understand why and how my cars been doing this. I though cam and crank shaft postion sensors but my car is so well taken care of....
My 2nd issue, is one with the dome light on the car, with the car on and the doors closed dome light has no type of function whatsoever, when the car is turned off and the doors are open is the only time I can make the dome light come on but the way it stays on I have to leave my finger on it lol soon as take it away it turns off.
Well I am a Floridian Subscriber and I admire your honesty in doing thing , I really understand this video but I did see the previews one, but I kind of can figurate out , would I need to use your paid channel ? I am Andherson .
you can access the paid channel at www.schrodingersboxqm.com
Ref Lo, why not secondary validation from COP.
Exelent
Good trueining
Thenks
Black Bird hahaha 💪🏻😂 👍🏻
Nastyyyy
Can not find your video on complete rear axle repair.
Its on my website at www.schrodingersboxqm.com
Hope your doing good Matt. Do you think a used snap on verus is worth buying in 2020 or is there current products on the market that does the same thing thats cheaper. i found a verus for 800 bucks thats with a whole kit and a modis for $500. is there another similar product with the same technology nowadays that isnt redonculously expensive?
Its absolutely worth buying. It's still as viable a tool as when I got it several years ago. Absolutely.
I'm the idiot, I'm a professional tech UK,, I get the content I'm not too bad at all with electrics. I watch the free channel have paid for the sbqm for ages anyway, watch it (admittedly not enough) and just don't worry about the pennies. As long as Matt keeps making the odd VS Cat video I'm happy 😂.. hopefully you get some bites. Merry Xmas 🎅
Yes another cat vs troll coming!
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.
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,
@@SchrodingersBox I wonder if GM kept the Ref Lo pin name from their old bypass ignition system but put a sense coil in to verify a sufficient spark event by a small pulse?
I had this car at the garage. When you accelerate suddenly for the pedal to touch the ground, the engine don't pull much power and the sound is very little but when you accelerate gradually for the pedal to touch the ground then is runs normally with the require sound....can you please suggest what might be wrong with the car?
Start with the basics. curve the fuel trim against load with TPS and induction metrics. The fault will be apparent.
Matt, What are the web / youtube links to Parts 1 & 2? I am a paid subscriber.
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 RUclips. Keep up the good work.
any LED testlight is safe.
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.
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.
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.
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.
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.
Turning mechanics into scientists one brain at a time. Thanks Matt.
Thanks man!! See you're never too old to learn!
Hi Bernie. 🙂
Hello again!
I'm wondering if you can help me please? I have no power to my fuel pump and my coil. Have checked all fueses and relays. Have power to fuse box. But it's missing ground to the coil and fuel pump. If I run a jumper wire to fuse panel where I'm missing ground to fuel pump. Push relay back in to complete the circuit and hold wire. Run wire to ground. I can cycle the fuel pump. But still on power to the coil. The problem is kicking my but. Please help!
Try a CKPS bypass
3rd world country need this trouble shooting knowledge I really love your channel
Help please thanks
Hi buddy love your videos very educational i was wondering if you had some advice and no Mechanic can help me my diesel cant hold idle unless i hold the revs it just stalls when i come to a stop or just at idle if can help much apreciated thanks very much buddy
Sure. what data do you have? Anything could cause that. Need basic fundamental data for a starting point.
@@SchrodingersBox i dont have live data at the moment im waiting got my diagnostic tool to come that way i can get live data and get back to you if want ? Also can do relearns then to ive replaced few things like suction control valve and crankshaft sensor no different blacket the egr mine a diesel 2.2 x trail t30
Does Mississippi count as a third world country? I see where I asked the same question 2yrs. ago. Dude I am serious. 3.50 a month is a lot to some of us. I love your channel, you have taught me so much. I noticed that you don't put a lot on the free side anymore. That is kinda disappointing, but hey I understand.👍🏾
I'm not going to watch this right now,I'll wait until my nuisance family have ate all my grub,drank all my booze and buggered off home,then I can watch it in peace. Merry Christmas big guy!.
LOL- just buy a lot of liquor-related gifts for them and you should have the day to yourself!!
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.
Hahahaha. Pretty much nailed it lol!!! The story about those giuys beiung the ones in line at Autozone is true too, isn't it? Just last weekend a guy in front of me asked price on a battery and an alternator... He decided to get the battery which was cheaper and if it didn't fix his no start, he'd buy an alternator
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?
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.
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
Where is the link to the paid channel?
Www.schrodingersboxQM.com.
I wan understand low ref ?thanks
Me too!!! I'll figure it out on the next video!
what is this guys day job hes very knowledgeable
I am a molecular biologist.
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 ?
Wow. I would love to see that video. No- never heard of it and makes absolutely no sense to me why that design would be functional. If you have a link please post it!!
@@SchrodingersBox Not an expert on adding links in the comments, however if you you go to the scanner danner channel and look up VW Passat No start Case Study Part 1 published on June 1, 2019 you will find it. He assumes the fourth wire is a feed back signal and realizes it's not when he looks at the wiring diagram. Seeing that the fourth wire goes directly to ground he can't explain why until a smart student in the class offers the solution.
ha haah aaaah haa haaa i love the way you talk to the haters.... i wanna do that tooo.. lol
How to find the cause of rattling sound in honda engines?
Same as any engine. Listen for where the sound is coming from and then look for damaged components.
@@SchrodingersBox dirty or stuck VCT valve can also cause rattling noise?
2nd!
Hahahaha I don't think so lol!!!
Hey Matt how are you doing man? I am in need of some serious help, I have a nissan Murano 2006, a crank no start. Battery died on me an I do not have any codes that I can go off. I tried replacing the camshaft sensor bank 1 and crankshaft without any success. I do not have much knowledge on electric systems.
I also tried starting fluid in the intake while cranking it and still am not able to get my car back on. Thank you.
check for spark.
@@SchrodingersBox I checked for spark, it has a spark. I ended up taking it to the shop, they told me the cylinders do not have enough compression, and that I needed another motor. Cylinder 2 shows 75 PSI, and the technician said it should be somewhere between 150-200 PSI Is there a way to try and fix it without going that route of getting a new motor? Maybe replacing cylinder rings or gaskets?
I agree with the technician if that’s what he found. Any jerry-rigging to bypass proper repair would be very ill advised.

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?
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.
@@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?
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 wrote the email to you, is it possible to pay with paypal for SBQM because it is the only option for me?
Sorry- at this time PayPal is not available. But I am considering moving to a new platform to do that. I prefer paypal too!
@@SchrodingersBox please check your email from me if you can :D i was thinking if you can manually turn me on and I can pay you with my paypal, thah way my idea?
