How much did they pay you for this advert?
@@lewiskelly14what kind of question is this?
@@baroutes A fair one
Thanks for sharing Dan, really great case study👍
Stay Safe Bro👍
@@lewiskelly14 who cares ... this guy should be milionare,,, from his videos milions of people have saved milions of money solving easy stuff when some mecanics just go and swap parts until they solve it or until u guet enought and go to another place...this guy is a genius,,,he is a automoville god ....
A brilliant example of why a test light is so important
Yes and in some cases, a home made head light 4 amp load test light.
or actually using an ohm-meter instead of continuity. A test light is still too low of an amperage to show any big thermal resistance changes in bad connections.
7:11 he shows the reason why I use ohms when voltage seems to be "floating". Whenever I see voltage going somewhere but there is no real power, or amperage, "no power" situation, then I just disconnect the voltage and check the resistance, or you could just see that when the engine is on there is still below nominal on the connector, as the ABS loads the circuit down. There are of course exteremely marginal cases where some hot spots and thermal expansion can make the results unreliable, but I rarely ever had to use a test light, as it's "too" dumb.
Also, don't think I'm calling Dan dumb, no, his methods are right, just not the ONLY correct way. Still I watch him to learn some interesting faults :)
@@tomclanys That would depend on the circuit amp draw. Most of those computer nodes/modules etc work with 5 volts and very little amperage.
No pun intended? (brilliant/light)🙂
@@Garth2011 yes, and by using a test light to check such voltage lines (for example powering a hall sensor) you risk overloading them and destroying your ECU. Most have protections in place, but it's still a risk.
A perfect example of VOLTAGE DOES NOT EQUAL CURRENT. Well done DD!
Exactly! Some people dont see that relation!
@@Diagnosedan can you recommend a good test light please
@@aa-kv2pq get a few different ones with different load currents. ~50mA, ~500mA, ~2A. So you can choose the correct one according to the circuit you're testing (similar to the typical load on that circuit).
A test light is such a simple device, there is really no good or bad.
Nothing better than fixing a car that came from multiple shops.
Great work Dan!
One of the few channels where I'll watch a video all the way through - always something to learn from you, Dan! Great video 👍🏽👍🏽
Thats great to hear! Thank you!!!!
Wow Dan thanks for another great video I'm a junior tech in Africa and I gotta say I've learnt so much from your channel and hope to learn more keep up the good work man
@DiagnoseDan I think we have someone pretending to be you
Thats great to hear!
Wow Dan, excellent example of the importance of voltage testing under load! DVOM would definitely get someone in trouble 😅
Neat Autel key programmer too!
Wow surprised to see you here Ivan, you don’t need to watch Dan you already know everything 😂 but glad that you support another great tech!!
Thank Ivan, we both know how important testing under load is, but there are still alot of techs out there not getting the message!
Your the man Ivan ! love your channel as much as Dan’s
you need to buy a loadpro Ivan.
@@TheDisgruntledMechanic I would never actually waste my money on anything so useless...doesn't even make a reliable wheel chock LOL!
Such a brilliant teacher. Thanks Dan!
What a wonderful teacher and of course super mechanic
I had a similar issue with my Golf IV, i.e., MK4. The alternator stopped working because it did not receive the control voltage it needed because the fuse box had some corrosion. I got stranded with a flat battery. It took weeks to figure out what was the issue and I ended up replacing the alternator in the process even though that was not the issue. I didn't have a test light but thanks to Dan, I do now :)
At least you have a new alternator you dont need to worry about anymore🤣
dan, you caught the automotive electrical lesson of the year by showing the loaded circuit and what it does with a voltmeter on video. i've seen rookies and experts bit by this and caught myself a few times. it all goes back to the basics and understanding how your test can affect a circuit AND how your circuit will affect the test. its got to be complete volta amps ohms to be a verifyable test. kudos !!!
Probably one of the best videos on this subject.
Dan, you are a wonderful gift to the automobile family
Another great video, Dan. Practical, useful and your explanations as to why you're doing what you're doing are outstanding. Best RUclips Channel.
Wow that's a great compliment! Thank you
I love your videos. You make it all very clear and explain so well. Great point about using a test lamp.
Thanks! Glad you liked it!
As always Dan, he is an expert at fixing these things!!
I’m learning new things every film you make! Good work Dan!
Thats so great to hear. Its good to hear the videos are helpful!
Hey Dan I became very addicted to your videos and the knowledge passed on is sensational, and very thoroughly explained, please don't stop making them. Thank you very much
Wow, thank you
these kind of comments are the reason i'm uploading video's.
I'm glad i could help and i really appreciate your comment!
Always enjoy your videos. Wish there were more of them. 🙂
There are more🤣🤣
Excellent job. Hard to believe a shop can miss this.
Indeed but true😓
Great video Dan, shows the importance of checking supplies and grounds under load
Exactly!
Thanks Dan! That's actually a super simple tip but a golden nugget! Even with 6 years experience and knowing all this, I'm pretty sure I'd have fallen for that mistake too and this was a good reminder! 👍
Hopefully the video was helpful!
Another excellent video Dan, Power & Grounds, sounds simple but a lot of mechanics only test with a meter, missing some important indicators, done it again Dan well done.
Thanks David!
Really enjoy your videos, especially as you expalin how you go about the diagnosis of the faults.
Always follow the right steps and most of the time that will lead you to the answer😉
I learned something there. Brillant demonstration of the importance of using a test light.
I really appreciate your videos Dan, you really know what you are doing. Now, regarding that Autel programmer, you where lucky. I am a locksmith and I have a bunch of stories about Autel bricking Nissan cars while programming keys.
Thanks for the feedback, i'll be careful and do some more research before using it again!
Congratulations on the result! Once again you made a car owner happy! The rule of checking with the control lamp or a consumer, I learned it from you from several episodes! Good luck!
Thanks! Yes the workshop was happy and i guess so will the owner👍
@@Diagnosedan I look forward to a case with an Egr problem on any car in the VAG range 1.6 or 2.0 Tdi Euro 5 engines!!!
Hi Dan, As always you shown the basics which illustrates how important there are. 👍👍
Basic but very relevant!
I never failed to be impressed Dan, keep up the good work!
Thats a great compliment Sir! Thank you!
Dan, I own a 2000 VW bug 1.8t with the same style fuse block and I so appreciate your testing explanation. The chats that i have followed say the fuse block on top of the battery is prone to corrosion issues, and this VW has proven that a brass brush and some battery terminal cleaner and protectant will be my best friend as my bug gets older.
Yes I had the same issue, just the fuse block burned out on 2 of the fuses, so I went for the cheaper alternative of 2 inline fuse holders and crimped them into place, then used a ring to provide power to them. As VW on this one integrates half the loom into the fuse holder, a lot cheaper than the buy a new one alternative.
Yes the Beatle has a similar setup
Thanks Dan,even though testing powers and grounds seems easy task,but appears to be tricky.I love the way you checked for power around that bolt and appears to be half space powered, this teach as how corrosion could affect integrity of the circuit in strange way.fantastic investigation.
Basic but still relevant!
Wow. That was so simply explained and demonstrated. Even I could understand it. Great job, and thanks, Dan.
🤣🤣thanks!
Your videos deserves two thumb ups.
Moshitoa (south Africa
Great video. Testing with a test light is such a small thing to overlook. They can save you hours and also save your mood. The longer you take to diagnose something, the greater the chance of your ego getting involved in the process. I.E. "I know I'm doing this test right." Then frustration enters and then it becomes a whole big thing. I'm sad to say, I speak from experience on that one. Thanks for another great video.
Thanks for watching! Testing with a test light isn't only the best way but also the most simple!
Amazing work, for real. The way you have been diagnosing all the cars in your videos has inspired me to change the way I work on cars.
Thank you for sharing your great skills and knowledges
Thanks for the great comment!
I’ve learned so much from your videos Dan.
More than I have learned from any other channel.
Thanks great!
As always, amazing Dan performs a thorough analysis and finds a cheap resolution.
It is what it is😁
Nice find Dan, also I have a km100 and use it for factory keys, which it also does very well. haven’t had an opportunity to try the universal keys yet. I have heard from other techs that they are quality and last, I also agree that the ones I received with my km100 feel very high quality upon initial impressions.
Thanks for the feedback! Are there any downsides to the tool?
@@Diagnosedan nothing specific, just limited use on very late models, just like any aftermarket tool. I am a dealer tech so that affects me more than most. I haven’t had it fail on anything that it shows in the menu, I believe autel lists available functions per model on its website somewhere in case you need to look it up before offering a service to a customer.
Good video- so many guys like to use the multimeter or one of those beeping testers- A test light is so much easier and more reliable- you only need to find a good ground and then probe with the light - the multi meters don't have clamps on the probes so you need to hold both wires and then try find a place where you can set the display to read it.
The issue is they (myself inclusive) are scared of frying something when used wrongly. So it's important to know how NOT to use it.
Testlight is fast and easy!
Super diagnostic just shows basic steps working
This make easy to understand something like checking grounds and powers, thanks!!
Hi Dan, sounds like you might be struggling a little bit for air in this video. Maybe it's time Diagnose Dan had a wee checkup and Diagnosis himself? I am sure it's nothing but no harm in getting checked. We need you around for many years to come so you can continue to make great videos!
You are right.....i'm really getting out of shape.......and out of Breath 🤣
Dan that circuit test is the perfect explanation of voltage testing, and loading the circuit to test. This is why i have home made test lights with different bulbs to test many circuits with bulbs of different draws. My testlight is digital so it does not load the circuit. I made my test bulbs with "banana jack" ends so i can use them with all my electrical diagnostics kit. Awsome videos and thank you again for posting these case studies.
Thanks, Dan .A example of the Voltage drop concept, definitely I am going to share this video with my students
Thats great to hear! A basic but important and very relevant lesson! Also keep in mind to use different loads on different circuits, its pointless to use a 70mA testlight on a starter moter circuit.
Hey Dan, one thing to keep in mind when adding a key to Nissan, is always programming the original key first then the aftermarket regardless of brand. The reason is that some will lock the original key and can't use it again so you will be stuck with one key again until you renew the original and program them back in again.
Thanks for the feedback!
@@Diagnosedan you're welcome. Thanks for all your videos, very educative. 👍
Such a great fault finding tip in using the the test light to load the circuit, cheers Dan for another cracking video.
And thank you for your comment Gareth!
Nice work. Always a great video. You make it very easy to follow your diagnosis.
Thats awsome!
Great diagnostic procedures, got an A3 in now with similar fault. Thanks Dan
Love it, the simple test light defeats the fluke dvom. When was in school(20 years ago) the instructors would drill you to use a meter, "don't use a test light". I always had the habit of using both just for some redundancy in my testing. Love the video.
You are the best who is working with electric faults on cars👍👍👍👍
Not only do I enjoy your expertise Dan but your accent seems so like home here in West Michigan. Indeed, I worked with many Hollanders in the Tool and Die division at General Motors. But before that, I was and still am auto/truck technician. I consider you as a neighbor. Thank you for helping me become a better diagnostician, even into my late sixties.
So love these videos and your approach to the problem...such logic. 👍
Thanks for watching and taking the time to leave a comment its really appreciated 👍
Thank you! I would have never thought of the advantage of using a test light! I appreciate your wisdom.👌🏾
Dan, you are just brilliant.👍
Great video!!! I remember at Bosch school a few decades back they set us up with something like this. Always handy to have a test light that has a load. A great learning experience to any one who deal with electrics!
Simple and effective 😉
I've got 2010 Vauxhall Vivaro to diagnose with exactly the same problem.
So a very relevant video for me, thanks Dan 👍👍👍
Thats great to hear Danny!
Excellent video and really well documented. I have an abs issue and I also assumed faulty module, this is something I’ve not yet tried.
Well done Dan,very informative. I have eps light on no stop start...I'm gonna investigate this weekend
Wow, I've never thought of the load that the lamp applies to the circuit being so important. Thank you for this lesson!
That was an easy one, Dan. I need someone like you in my workplace. I have to diagnose all that crazy electronics by miself. 👍
Very educated and interesting video, this is the power of test light. Keep it up Dan, I was thinking of you 2 days ago that it has been a long time since we see you uploaded video before RUclips notified me this morning. Great work Dan!
I knew you were thinking that so i quickly uploaded a new video 🤣
Yep, the best channel for auto repairs. Very very profi
Hats off mr. Dan, the hardest repairs are the simple ones
Thats a big compliment! Thank you!
Best part of the entire video is the funny bits at the end,not taking away the utmost respect for the entirety of the tutorial, well done Dan, as ever, legendary work, keep up this groundbreaking pioneering field that many fear to tread. 🙂😇🥰
Dan, Thank you for another great lesson !!! I am also very glad to see your trial of the KM100. I have, for a number of years, only been using Autel. Even their TPMS MX sensors and programmers. All of which was leading me to think of investing in their key system however I had not decided as yet.
In general Autel is pretty good!
Excellent! Great job as always Dan your English is amazing, love the bloopers.
Thank you
I've not even watched this but excited when I got the notification. Left it uncleared until now just to make sure I watch.
Thanks for your diagnosis
🤣🤣🤣👍
thank you so much Dan for another great vlog! greetings René
Very usefull video, thanks for sharing your time and knowledge. Greetings from Spain!
Dan is a great teacher
Everybody needs a Dantool, u r the king!!! Thank u so very much for ur lessons 👌👌👌
🤣🤣👍
Always entertaining, always educational. Always a must watch. Cheers Dan.
Thanks Mark
Dan, you are a Master at your Craft.
Thanks!
This just solved a problem I have been dealing with for months. Mine was a loose fuse that I pressed in and the ABS and brake lights disappeared from the cluster. Thank you!
Powers and grounds under load, roger.
Great skills as always, DD! 👌🏻
😉👍👍👍
Your videos are always illuminating to be sure... The test light was truly edifying, I am a diy - I have been having a trying time with a bmw E53 with the EHC, after changing the air bags and the two sensors - the fault code was being stored in the head unit and transmitting to the read out. It did keep me out of the pub and off the streets for a while. Good onya
Hmmm🤔 Out of the pub?🍺...🤣
Good lesson on using the right tool for measuring power and grounds!
Exactly, good old simple testlight!
Just wanted to say a big thank you for another excellent video, I Was not very good with auto electrics but the way you explain it all makes it so very easy for me to understand , Thanks Dan, I appreciate you sharing your excellent knowledge with us.. Thanks again..
Wow ! You made my day😁
Dan, good evening from Germany. As ever, another master class in diagnostics. Brilliant. You may not upload lots of videos but they are gold standard every time. Thanks 👌👌
Danke! Its really appreciated. I dont get alot of viewers from Germany, i think because my channel is in English.
Great video Danny, always good to see you in action 👍
Thanks!
Enjoyed your video? I absolutely loved it and appreciate it more than you'll ever know.
Thank you
Love your channel Dan. Diagnosis made easy!
Thank you Ludwig
You're looking and sounding good - in the current world situation that's a relief. As a now retired electronics technician, I had fun with the ABS troubleshooting, and you reinforced something I learned years ago, where i was living near the ocean and saw lots of bad power connections and grounds. Not so much now as we're 1200+ miles inland these last 30 years.
Thanks for the great comment its appriciated 👍
Great work Dan. As always, once you know the fault a simple fix. But you found the fault by proving beyond all doubt that's where the problem was multiple times using different methods. Well done. 👍🏼
I always try to 100% prove a diag. to be sure i've fixed the problem. Try that is🤣
DiagnoseDan the expert in car diagnostics 💪💪💪
Thank you for sharing
😁👍
Excellent troubleshooting as usual and good tips about the keys!
Thanks!
Fixed so many faults others couldn’t using my incandescent test light. Got to load that circuit 👍 love your videos Dan.
Testlight is my favorite tool😁
Always learning something new from your diagnosis
Its great to hear you learn from my video's
Really enjoyed this repair because it was easy to follow.
Thats great to hear
Awesome example of multimeter v test lamp, excellent work Dan, thanks👍👍👍😊😊😊
Thank you very much!
Wow the difference between the test light and voltmeter was eye opening. Lesson learned
Excellent service
Nice information video about test light
Great testing and teaching!
So glad your shop is in our town!!
Great to see a local watching my videos 👍 Bedankt!
Great display of it showing voltage, but dropping with a load. This demonstrates why it's important not to touch anything without testing it all first. These are always the weird one's that fix themselves when you wiggle too many things around, and then you never find the issue and it comes back again later. Great video!
Yes indeed, i was also lucky to catch it on video. Before you know it all is working fine again!
Good old test light did it again... you can't beat it..
All the best to you, regards Roger
You are right, good old simple testlight.
Nice video brother, this info will help me up my skills now. Thank you Dan
Nicely found & fixed Dan 👏👏
Great lesson about loading a circuit.
Mr splinter !!! Of diagnosis!!!! Thank you for making me what I am today !!!! Without your videos idk if I ever woulda have fix the tons of **** I’ve fixed !
Wow that's great!!
Dan know wonder garages bring their problem car's too you. You make it look so easy.🇬🇧👍👍👍👍👍
I can assure you it isn't always easy🤣
