Checking Modern Vehicles Ignition System

Using the test light from previous video to check an engine for spark.

[@TheEgg185]

Also. I'm slow to understand videos like this. THANK YOU for taking the time to go slow and explain things in detail without missing a step. I was just thinking that this was one of the BEST explanations I've ever seen. Now I see comments from people complaining that you were too basic and repetitive. They can go to hell.

[@RomanAutomotive]

Most people think they know everything, or there way is the only way. You have to absorb information.

[@chadlavender5267]

Thanks bro, finally a 4 pin explanations. Now I just gotta figure how to test the 2nd to top wire

[@tonijohnson09]

Thank you for taking the time to put this video together. Here is where we learn from each other. So I won't touch on repitition. It was a little hard to get through and other users have already address that. Now what you just did have flaws. U can be getting a spark from the coil but its still not good. There could be a short in it that affects the resistance the computer knows it should get from the coil. I recently successfully fixed a Nissan that had the coil firing, but the resistance from the coil was very low compared to the others. This caused the check light to come on and the computer throwing codes of bad coil and misfire. Videos are on KZbin speaking on how to do this test. Yet and still. Great video.

[@johnnyz9927]

Thank you . I finally get it . You explained it perfectly . I appreciate the way you reiterate as your going along . I have a tendency to miss some things .. Great help.

[@dennisthompson7857]

Thank you , you explained it very well. Plus you did it slow for other that need it that way as still learning. .

[@tahsina.alkhuwaiter9990]

Well done. Thanks for sharing your experience with us

[@cowboyassass1n]

I was hoping that I wasn't the only one hearing the screaming children...lol.... No worries dude, they make a lot of noise, but they sure are fun!!! I have 5 of them!!! Tehy made a lot of noise, then they grow up and move out, and you miss the noise!!!

[@RomanAutomotive]

That's one thing you can bet on, people having children. I always tell people,"I can tell the future." They say, "how so?" I say,"the rich will get richer, and the poor will get poorer." Im always right Cowboy 😁

[@JahanZeb1976]

Awesome video! Keep up good work. Very nice video as always from you. Sharing nice videos on youtube is great and everyone should do that. Regards,

[@ceetwyce335]

Thank you for this video! And I thank you for doing it on this Toyota motor. I'm having coil issues with this same motor and you've shown me how to diagnose it.

[@edinm.6264]

Thankyou, very helpful and educational, Ignore the negatives they just lack patience brotha

[@drfirojtadavi]

Salute you man very informative video you have made , i will follow your procedures for my GMC Acadia having misfire 2,4,6 cylinder

[@mr88talent]

Funny, at 4:31 - "Trying to look for something to point with". Grabs a Sharpie. Hmm, maybe the pointy end of the test light might have worked. :)

[@mohammadtz337]

Thank you for very informative video , that is what i was looking for, keep on rolling.

[@MrJazzohjazz]

Is he teaching us from a day care center ? He should connect the power to the screaming child for silence !

[@martyturpen4535]

Yes can't you tell he teachs kids, WHOS WATCHING THE KIDS? GEZZZZZ

[@martyturpen4535]

First think it was yappy dogs , then kids his rambling the entire time. 10 mins Im done, learned how to use test light may be if not so confused. My anxiety an stress off the charts

[@kingkobina]

I cant stop laughing at this comment!!!!! 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣

[@siucbset]

GreatVideo: I learned a new way to test a coil. Most of the other guys just swap the coils out.

[@kenlow4028]

Excellent mechanic instructions top gun

[@MrNickelodion]

This is the video that mustbe watch for everyone on cars.

[@allenwalker8640]

i replayed this video and she is still hollering. got a torture ranch going on there.

[@tboneproductions2453]

Pull up design. Section 2 ScannerDanner! 😊 Good video. Cheers mate!

[@johnkatopodis7878]

Hi there. Thankyou for your tutorial..realy helpful and recommended..john australia 👍

[@RomanAutomotive]

Technically pull up is something different. I started calling it that because of what the waveform looks like on a scope.

[@dustinwb84]

Great explanation! Thank you!

[@ksk5517]

This could of been an excellent video. Camera angle is such that it is difficult to see which cable was on the lower row or upper row during your instruction. Since you are filming with only one free hand, perhaps using a better pointer would help in lieu of using a fat sharpie pen.

[@HotRod-wv4vm]

my 97 grand prix GT 3.8 is missing one of the purge solenoid vacuum lines. The one that supposedly goes to the throttle body. Exactly where does it connect on the throttle body. Thanks

[@nickb1875]

From yo explanation, I have noticed that those coils work th same as DC CDIs of motorcycles except fo th feedback wire. If the ampere and trigger voltage specs are th same, then they can be used as substitute of cdi and coil on motorcycles. Its like a cdi with ignition coil internally

[@tajhealthnature8570]

Good job. 👌👌👌

[@Wolfbain2917]

Thanks dude

[@robertdiamondoil2384]

Great video

[@xavierbrown111]

nice information! so what test light is safer to do that test your doing? what kind is that?

[@anastasiusadelbai2997]

Thank you now I know I need to buy me a test light with low amp

[@alexthegreat5208]

@RomanAutomotive Is there any way of testing the signal wire???

[@bobcat8439]

Great info thanks

[@lovesoul30]

Thank you so much. It was really intressting.

[@TheEgg185]

Is that just a regular 12v test light? Or a special lower voltage test light. I don't want to ruin things with it.

[@kennedywong9854]

We have power but how much voltage are we seeing with test light?

[@tilekkapas7939]

Very good!

[@cg3ssf]

HhaahHhaahH HOLY FUCK WHOS THAT CHICK GETTING SLAMMED IN THE HOUSE... WTF... DONT HELP US ... GET IN THERE

[@eljuarense]

Nice vid,, Thanks,,,,,Don't pay attention to the haters

[@ralphwatkins1400]

good information to remember

[@Xantylon74]

But the coil could be damaged if you don't have a perfect ground for the spark. As far as i understand, the spark goes back to the coil and it can destroy it.

[@guidojones100]

Thank you!

[@r3alfish]

15:25 making a cool beat

[@Hate2Loveme1991]

Hey man great video but what happens when you're looking for a ground and you hit power? Do you get sparks and melted stuff?

[@juanmelo2064]

Great video! But how do you test the wires coming in and out the computer?? I have an issue with one coil not receiving enough power!

[@kingkobina]

I'm going to go out on a limb and say Scorsese had no input directing this video. Bro you did such a good job explaining this but maybe get someone to hold the camera, put a sock in that kids mouth and re do it. I will say with all the distractions you did help me so I had to smash the like button. 👍👍👍👍👍

[@user-kq7cy2vo7j]

thank you

[@generalpress]

Good Job!

[@tonyduong3639]

what tool is it? where can i buy it? Thanks

[@eastmanautorepair5130]

Good video one of best out there

[@user-kj6cw1wl7u]

Where are the fuse located?

[@charlessteele2226]

noisey ass kids in the background!! . my neighbors probably think im watching a porn.

[@dogmutty2]

Lmfao x10

[@allenwalker8640]

who is that woman being tortured in the background of your video?

[@frozenmike5061]

What if the camshaft is not working what would be the problem

[@JSW42]

How many times must you say something? Once is quite enough. Put a banana male plug on the end of your test light with a Fluke sure grip alligator clamp. It is easier to use and if you yank on the test light the plug pulls out without breaking the wire.

[@jomarcatubig4971]

What wire i can connect my after market tachometer?

[@skulz1974]

Brother.... you’re a great technician , but you need to think things through... You’re explaining/teaching about ignition systèmes and ecm related actions , no need to explain how a test light works...... Keep it simple : say things clearly , and say them once.... It’s incredibly hard to follow. Positive critisism buddy, I’ll watch more of your stuff for sure!

[@kiev24]

agree 100%

[@TheEgg185]

disagree 100%. I find things like this very hard to understand and confusing. I appreciate that he took the time to explain EVERYTHING, even if a lot of those things were things that I already knew.

[@kermitdiaz6937]

man how can you test the igniter

[@shamaiyachristian4199]

will your car smell like it burning after you drive it with the coils badand turn off engine

[@rashidbalochbaloch9010]

thanks dude

[@alstevens44]

Is that the wire from pcm mark IGF

[@salvadorgutierrezr5914]

Do you sell those test light, or where can I buy one?

[@shikanyota]

matco

[@user-kj6cw1wl7u]

I dont have power where is the fuses

[@bunakkaptan]

A bit clumsy but seems OK

[@federberer3681]

Background noises are disturbing!

[@thejackel1844]

What's the story with all the screaming ?, sounds like someone's being murdered...

[@qoubarachid11]

It's more confusing than anything else

[@kylalacibal8131]

wich wire did u test, using test light from positive to gruond wire or signal wire..ty

[@AIRMANBEAR]

HE TESTED THE WIRE THAT WAS A DIFFERENT COLOR ON EACH COIL (THE TRIGGER WIRE) THE POWER AND GROUND WIRES ETC WERE ALL THE SAME COLORS

[@AIRMANBEAR]

USE A POINTER NOT YOUR FINGER (TOO WIDE)

[@stevenb7199]

YA great...Not. Thanks for explaining that all the wires are the same except for the signal wire. Explaining it 75 times was a lil overkill though. Couldn't watch the whole video because I got tired of hearing about the fucking wires over and over....

[@johnd942]

HOW MANY TIMES DO YOU NEED TO REPEAT 4 WIRES BUT 3 ARE THE SAME!.....driving viewers mad!!! Terrible 'gas-bagging' without actually doing anything!!

[@RomanAutomotive]

+8233Eire Thank you.

[@slycat4228]

Good job explaining in detail I will say... "A bit repetitive, but informative and this is officially the very first review I've ever taken the time to respond to..? Your intention has merit- with no foreseen ban intention... For that you are a gentleman & a scholar. Good day & Godspeed To You & Yours... Li'l more homework on the approach tho fella

[@themotorcycleguy5980]

Oh mee...

[@runthomas]

waste of time, .... just test the coil as he stated...if it works then everything is ok ONLY IF THE COIL DOES NOT WORK do you check for power and check for earth, and check for signal whats teh point in checking everything if the coil works? there is no point another thing yuo can do to test the coil is ...remove a spark plug and put it in the coil....then you can just see it spark or not, when you liven up the signal wire instead of messing about all over the place trying to get a spark. ...ps take 2 spark plugs out in case the one that you are using to test with is damaged.

[@moonlightmelodrama]

You've got to edit your stuff before you record. Too much repetition.

[@mechanicandskills7215]

First of all after listening to your video near the end i am sorry for the death of the child in the back ground..lol...Any ways manly skills dictates you NEED duck tape every man needs duck tape...pls next time if ever duck tape the f'in coil down ''GOD so frustrating to watch "" But informative video thank you mate cheers.

[@dogmutty2]

Lol...kids

[@nathanielvaughn-pappas5374]

What the hell

[@MegaLinov]

Bravo but talking to much

[@joe226825]

Your not talking to a 2 yr. Old So quit repeating everything. Camera work was terrible, too close and jumping around. Could have been explained in less than 1/2 the time. Subscribe? No Way !!!!!

[@danpettis1675]

All the same color....all the same color ...all the same color. All the same color

[@Bosshogular]

Ohhh my god dude. Little bit of good info. But you’re soo painful to watch. Edit your clips ffs. If you don’t repeat everything 50 times you coulda kept that video to 5 minutes.

[@joshroa85]

Oh my God dude... you are unbearable.

[@keithjoyner9998]

Get to the point you are wasting alot of time doing nothing
