I appreciate all of this info in one video and with time stamps. The only part I have a different opinion on is with checking resistance. Checking for power and ground or the resistance of a wire is not a good test. It is only helpful if you understand the limitations and there is not high resistance. If you have an open circuit, then sure resistance is helpful. If there is high resistance in the circuit you would not see that unless you load tested those circuits. A single strand of wire will show good resistance and show you you voltage until they are loaded. I have found so many technicians do not understand this and continue to rely on resistance alone. I use resistance checks from time to time and I understand that if it tests good then that doesn't mean the circuit is good. It can be much quicker some times to just check resistance and if I find an open circuit then great. Just my thoughts. Otherwise this was a great video.
Hi there and thanks a lot for sharing your thoughts. I agree as I’ve seen many cases that the regular resistance check is not helpful if there is not open circuit. But what I’m trying to do here is at the first place, I present the recommended details from the workshop manual as this is good for the basic troubleshooting. But of course there are some other methods that I prefer to present in another videos, just to avoid any confusion. Normally I use picoscope many times but I just mentioned it here and will explain it separately. I appreciate your kind words and sharing your knowledge as this is how everyone must be.🙏🙏
I use resistance checks mostly to confirm that I'm on the right circuit, theirs no open or short to ground/power, or the circuits are no shorted together. Then I load the circuit once I have proven I'm on the right circuit
An externally-switched ignition coil is just a transformer. Two wires, a ferrite core, all completely encapsulated in epoxy resin. The only thing that can really go wrong is that the coil - a bunch of wire - is broken or melted. Particularly the secondary coil. The resistance test covers the normal failure modes of a transformer.
@19:23. The multimeter's positive probe was on the IGF terminal not the IGT terminal (i.e. trigger). The IGT can only properly be tested with engine cranking or ON. The IGF can be checked when ignition is ON (which is what you showed), engine cranking or engine ON. IGF (when ignition is ON) will show about 5V (it only switches to near 0V at the moment the coil sparks during engine cranking or engine ON).
Hi there, thanks for your comment and for reporting the issue. You’re correct and as we explained in the previous parts of that section, IGT must be checked when engine is running. There was an error during the video editing and it has been already rectified. Thanks 🙏
So interesting this my shed some problems ,I'm having with a fiat dobolo although it's a diesel it possible has similar types of electrical wiring ,thanks for your video so useful Many thanks , I realise my knowledge is some in the x Stone age .
If you have a plug-on-coil/direct type ignition coil and are having trouble getting any resistance measurement of the secondary coil by touching the test leads to the sparkplug contact and any of the pins, and you know you tried everything, it means the coil is burnt/blown/broken. You can verify by testing a brand-new coil at an auto parts store or whatever. That's what I did. The coil can still work even if it is blown and melted inside, but obviously, it won't work forever because eventually the spark won't be able to jump the broken inside parts of the coil.
thanks for the video,im trouble shooting my sons car now with 4 cyl with 2 wasted spark type coils,1 has 15k ohms the other which is for cyl 1& 4 which are the ones that are misfiring has only 7k ohms on 2ndary coil
Good video. It would have been helpful if it had something showing each pin specifcally labeled. Example: showing pin 1, pin 2, pin 3, and pin 4, which one is: +12V, IGF, IGT, and GND.
Hello, @12:38 the resistance is below 6, is the ignition coil good or bad? What is the minimal allowance of how low or high resistance can be past 6-8 kohms. Also when testing the Ignition coil ground circuit for resistance at the connector does the car need to be in On position or off?
Hi there, thanks for your comment. That difference in resistance is still acceptable, normally if there is anything wrong, resistance value will be much higher or lower, this difference was only less than 1 ohm which is nothing importance. Many workshop manuals accept 15% higher or lower than recommended resistance. For the second question, ignition switch must be off.
Hi there, checking the 4-pin ignition coil is not as easy as 2-pin coil because it has the ignition module inside which makes the multimeter inspection very hard and normally you won’t find any specifications for 4-pin ignition coil in workshop manual. So as so did in the video, so would check the wiring, and for the coil itself, I would swap it with the ignition coil from another cylinder, so if codes moves to the new cylinder it shows that coil is faulty.
Can you please tell me the pinouts on a Mercedes 4 wire ignition coil used in m274engine? I can see a battery source, ground, ECM trigger, but the 4th wire is what I don’t know. Please your help will be greatly appreciated.
@@AutomotiveDiagnosis thanks. I tried tracing this wire in my car and didn’t get any continuity with any pin on both ECM connectors, please would you be able to provide me with wiring diagrams for my car engine electronics (2016 c300 w205)
I have 2 wire coil on plug ignition coils. I tried 3 multimeters and could not find resistance on any secondary coils. I tried 200 ohm, 200k ohm, and M-ohm settings on meters. Still reading O.L. These plugs are 2 spark plug coils. I tried finding secondary resistance using every touch point combination available as well as switching leads in case of polarity issue or one way diode. Any thoughts? What am I missing?
At 12:35 the specification is 6.0 to 8.0 KΩ The multimeter shows 5.34 KΩ is that a bad ignition coil??? We must replace=change the ignition coil?? Or we can test If there is a good spark When we crank the engine???
I had the same problem measuring. It seems insane to me that the secondary coil wouldn't be directly connected to ground by design. Also seems insane that any diode would be put on a high-voltage secondary. More likely the coil has failed, right? I will test with new ignition coils.
@@TopGunMan FYI The coils I was working on were good and functioning properly. The secondary on these new coils is not wired like the old coils. The ways you can test are with an oscilloscope or keep primary connected and zip tie the plug in place out of the vehicle. Just remember to tie a ground strap to the plug so you don’t fry the coils. Then compare the spark with that of a good plug.
Very good up to the use of a 'scope' for the 'signal' test - surely I don't need a scope, a simple test light will show the 'signal pulse' ( by flashing), while swinging the motor ? I can't get mine to flash however! Any ideas going forward?
Hi there, thanks for your comment. That way we can confirm the presence of the signal (trigger), but normally we can get more from the waveform. As I explained in the video, by analysing the waveform we can check the dwell timing, pick voltage and spark duration that each one of them gives us some clue about the possible problem.
I'm a little bit confused on my particular vehicle. I have a coil on plug. It has 3 pins on the coil but the plug that's on the wiring harness has 3 pins but only 2 of them have wires going to it lol.
I have a 1980 motorcycle GS 850 ..I was thinking of adding coil on plug coils to get a hotter spark..it isn't points and condenser..it's a duel module pick system.. Is there a c.o.p.that would work for me ..??
Ok at 18:49 the testing of the coil connector here are we to universally gather the connectors are numbered 1 2 3 4 as their respective pins, so is red probe as illustrated placed in pin 1 or pin 4 ? With red lead probe in the connector and black lead probe ground placed on the engine valve cover to obtain the Voltage reading am i correct or am i way off base with this ? I have some of these misfires in cylinders 4 5 and 6. I know it cannot be spark plugs they are brand new. those three coils are not brand new. So how do i rule out these 3 coils to know that the issue is with my 3 fuel injectors at that point?
Thanks for the video.I have a question , coil pack has 4 pins , and multimeter shows infinity all the combination of 4 pins , so you think coil pack is bad ? My car has significant power loss for last 2 years
Most of the ignition coils with 4 pins do have an ignition module inside which makes the resistance inspection impossible so reading the infinite value doesn’t make it bad. Do you have any fault code too?
@@AutomotiveDiagnosis no faulty code.I ordered new coil pack , let’s see if I’ll see any difference.I already replaced the Cat , don’t know what else could be the reason for power loss.09 Outback 215K mile
Normally if you have access to the OEM workshop manuals (from dealerships) that's the best way, but you will have them only if you work in a dealership. Some companies also provide the workshop manuals for many different cars that you can buy a membership and get access to the manuals (like ALLDATA), there are some online websites too.
Hi there, there are two ways. On some cars, the positive wire is a bit thicker than the negative wire. But the best way is to check the voltage on them when ignition switch is on, the one with battery voltage is positive
So I have a no spark issue with my car, and I couldn’t find what it was, after doing some testing I’ve come to figure out possibly that my ignition coils aren’t grounding, what could it be? I use a test light on both of the terminals on the harness, they both get ground when the ignition is off, And they both get voltage when the ignition is on. But when I go to crank, the test light doesn’t blink, indicating that it is not forcing ground when that cylinder is ready to spark. does anyone have any information for this to help me out? Did I do the test incorrectly? or does it simply not work that way?
Did you find a solution??? Instead of test light you can use an analog volt meter when you crank the engine, the instrument needle will move I don't know if you can read something on a digital voltmeter
One of my Audi A3 coils has a primary resistance value of 0.9, while the others have something around 1.6. The ones with higher values are bad, right?
@@AutomotiveDiagnosis I have a missfire problem at low engine speeds. Around 2 thousand rotations per minute. Sometimes it fails. But I don't understand if my spark plug with low resistance (0,9) is good or if the problem is the others with a higher resistance (1,6). What are acceptable primary resistance values?

But on the car there are 6 electric spark plugs leads.how can i connect the other 3 pin for the car to start?i have just upgrade to the 3 coil pack coz the original coil pack are very expensive
I'm not sure if you bought the right part. Coil packs might be different as you see in the video, if you don't have all high tension leads, you might not be able to install.
@@AutomotiveDiagnosis htl sre there. What i need is how to power those coils coz on old pencil coils there are 6 electric leads and now on the coil packs that i have is 3 coils with 3 electric plugs.each coil is firreling two pistons
I don’t understand how am I supposed to know that a 3 pin coil is bad there’s no specifications to know if it’s bad Neither I can’t test triggering signal if the car I’m working on dosent turn on or spark
When you have a faulty ignition coil, most likely you are able to start the engine but of course engine will run roughly. Each three wires can be checked individually for short or open circuit even if engine is off. For the ignition coil itself, the best way if to swap it with an ignition coil of another cylinder, then start the engine and check the fault codes, if misfire or ignition coil fault code moves to the this cylinder, it confirms that ignition coil is faulty.
Hello, i have a seven pin connector to a igniting pack. It's what you see on a chevy cruze. All 4 coils are connected this long pack. How do i test this?
Hi there, You can find the ignition coil wiring diagram in the link below (Cruz 2013 1.4 L), I will also keep an eye and will make a video if I have any Cruz this week. drive.google.com/file/d/1WnZpP6SmPZZZ6CUPm4x3K5b32kSOKDft/view?usp=share_link
Continuity is for checking the open circuit on the wiring. If any wire is open, there is no continuity when you check it from each end of the wire with a multimeter
I simply want to test my ignition coil. Don't want to sit through 22 minutes of video that talks about all the other stuff that I don't care about. When this video gets to my type of ignition, I don't know if that video portion is dependent on some other other portions of the part of the 22-minute video, and the explanation is a lot of technical gibberish. Be concise, be precise, avoid tech jargons, stick to simple 1, 2, 3 steps to do something.
Hi there, obviously there are so many systems and technologies in the car and not all of them are easy to understand for everyone and we can not just talk about the basic stuff while it won't be helpful many times. Anyway, could you please tell me what is your car, what type of ignition coil you have and what is the current fault?

Scan tool gives you some information but it is not going to point to the main cause, most of the time, some test and measurement are needed.
The computer monitors is but you can’t really see that data unless you use a data link connection or like he did with the scope and dmm

The music makes noisy
“Multimiter”??????
You mean you have seen one spelling error?
I simply want to test my ignition coil. Don't want to sit through 22 minutes of video that talks about all the other stuff that I don't care about. When this video gets to my type of ignition, I don't know if that video portion is dependent on some other other portions of the part of the 22-minute video, and the explanation is a lot of technical gibberish. Be concise, be precise, avoid tech jargons, stick to simple 1, 2, 3 steps to do something.
Hi there, obviously there are so many systems and technologies in the car and not all of them are easy to understand for everyone and we can not just talk about the basic stuff while it won't be helpful many times. Anyway, could you please tell me what is your car, what type of ignition coil you have and what is the current fault?

Get rid of the damn music!
M.a
I really hate the computer voices.
It’s been more than two years that we have not used that voice again. If you check other videos on the channel, they are all our voices.
Ai voice really? So its a faceless UA-cam... downvote this.... I want real people with real knowledge and experience.
Thanks for leaving the comment without checking the channel page. This video was made more than a year ago, it’s been a long time that we put our voice on the videos when we record them on the car. And all videos since 8 or 9 months ago are recorded with our voice.
Very helpful
Glad you think so!
