No talking, just action. I love to see it.
trying to bring my 1970 gmc back to life and have a feeling the coil isn’t giving spark, can’t wait to go home from work today and try this out 😊 GREAT VIDEO!!!!!!!
Great vid! Simple and to the point. Instead of using a battery, I used a battery charger... Worked great.. Thx....
Excellent! I have a 1981 Renault 4 that was not sparking. I followed the instructions in this video, and was able to confirm that the coil was indeed working.
thanks. your demo helped me test my coil.
Super great check demonstration , thanks
Simple and to the point. Thank you.
Very good demonstration. But you can have a coil that works perfectly fine at low rpm and or when cold, that overheats and breaks down at high rpm. Back in college we had a rig that was essentially a spark plug and a set of points with an electric motor actuating them. You plug the coil in and leave it. Ten minutes later, if it was getting really hot and or the spark broke down when revved up, you knew it was bad.
got an iddea how to build another test rig like that?
@@stevenkerr1455 Well, the quick and dirty way to do it is with an old knackered distributor, take the gear off the bottom and chuck it in a drill. Then hook it up as per usual.
If you wanted to build a test rig, you'd need a motor, an eccentric cam, points, some type of RPM monitoring tool or a rigged up tachometer, some leads and wires, and some type of surface to mount everything to.
I have mercriuser 120hp and after of little bit of driving the coil is geting very hot and boil some liquid on top,maybe some one give an advice.
@@adrianababa3288 Coils are filled with oil, it serves as a coolant, moisture ingress inhibitor and a corrosion preventative. If there is oil seeping out of the top, the coils is done, as in, it is already dead even if it is still working.
I am not familiar with that vehicle, but you could try to find out if there is a ballast resistor, or if there is supposed to be a ballast resistor and a previous owner has removed it.
Ballast resistors are simple ceramic heat resistors that go between the ignition positive source and the coil, as they get hotter, they restrict power to the coil. When starting from cold, they provide the full 12V, as they warm up, the voltage drops to around 9V, which is more than sufficient to run the ignition, but crucially not enough to cause overheating of the coil, and reduces the possibility of arcing at the points. Remember the alternator can push between 13.5 ~ 14V into the system, more if the regulator is malfunctioning, so check your battery voltage with the engine running at fast idle and a bit beyond as a first precautionary step.
A lot of people in the past removed the ballast resistors as they do cause unusual and intermittent ignition problems when they go wrong. However removing them when they are supposed to be there will wear out the coil and points much faster. Some later ignition systems have an in built ignition power regulation system, so once the engine is warmed up, check the battery voltage and then check the coil voltage. If the coil voltage is lower than the battery voltage, it is most likely that there is a ballast resistor or a voltage regulator fitted.
It sounds like you already need a new coil, so don't cheap out on it, parts from the far east at discount prices from eBay and the likes just cause headaches. Get an OEM coil, or an equivalent from Lucas or Bosch. Or you could go chicken oriental and get an MSD coil, but do the necessary checks first.
I'm going to assume (and hope) it's just worn out, but you can never be sure, so don't assume because you need your car to get around.
This was more helpful to me ! Thanks
All i can say is thank you
Your explination was
To the point with out the CB point.
Absolutely great video, def would’ve appreciated u talking it through bc I’ve got comprehension issues so I had to watch ur video 7-8x to make sure I did it right, but I figured it out and worked great!!
I looked for days for this video!! Good job
Thanks for the comment!
An useful video, thanks!
Fantastic demo very clear result, please do a demo on how the igniter or the transistor could be tested
very useful thanks!!!
Good job brother 👍
Nice video. Thanks
Thank you
Gret video thanks, even I understand it....
Thanks that's amazing great video channel I like it nice ideas
Thanks a lot! I am very pleased!
Very easy step thanks
Good Video
I just checked my coils this way. I didn't see a lot of spark but I did see some.
Good sir
All right....
Great
easier way: connect a aa battery on one of the outer 2 contacts then put one finger in the middle contact and another finger on one of the outer 2 contacts. then connect and disconnect the AA battery to see if you get a shock while disconnecting.
Thanks a lot for the advice! I have to try)
@Fayan TV
If you have health challenge like heart problems or wearing cardiac pacemaker, epilepsy etc., don't try it or consult you doctor. High voltage present, risk dysfunction of medical devices and health
@@adeyemibabatunde1814 agreed
Gets me going in the morning 🌄 🤣🤣🤣
When you have problems with your ignition, the coil is rarely the problem, I have worked on it for years, as a professional

Thank you .!From Kosova.
👏👏👏
So if you get no spark at the spare plug is the coil bad then?
👍 👍 👍!!!
Awesome and I didn't haver to listen why you painted your car that color!
Omg so 👍
Yes I suppose that is a test of sorts but you need to remember that ignition coil it’s boosting 12 V to about 20,000 V using a magnet immersed in oil it fires every time the points open in the distributor and as the motor is revving 2000 and 3000 RPM things get hot on the under the Bonnet the metal and components in the coil can expand under heat and internal defects or cracks etc can lead to the ignition breaking down so the bench test your performed is one thing but it’s room temperature low rpm it’s not a particularly arduous test
I think I’d be inclined just to buy a new coil to be honest
How would test a four coil one from a 1997 f150 4.6L. Can u make a video
I have 3 coils here, and 2 are brand new, both Lucas, for a 1.6 Ford crossflow, set both up following this carefully, I have full batter and it turns the engine over now probs, but I get no spark either are the plug or on the ground leads when I test. What could that be!!
How to wire this coil to golf Mk1?
What is the reference of the black cabe you are using ? thank you
ดีมากครับ
It sparks but is the spark strong enough? It looks ptetty weak.
How do I check the voltage to the plug
Thank you! I am trying to understand why my 1947 John Deere B won't start. I know it is getting fuel to the plugs so, must be spark. It can only be three elements: Fuel, Air, and Spark
4: and compression...
Time
is that just a regular spark plug wire ?
Dang that simple.. thank you
Bhai mere old bike battry new hai but charg nhi hote light bhe bhot low jalta hai ... 60 ki speed me bhe amp kata + me nhi jata?
Dobra robota ! :) Pokazałeś przy okazji gdzie jest + na cewce.. ;)
Leci SUB ! Pozdro ! ;)
Unfortunately all I know now it isn't the coil.
Why his testing look like the spark is higher than the spark plug terminal ??? It should see the higher spark at the end of spark plug ,
But what happens of you just hold it there, does it give spark all the time?
No
What do you mean by + or 15? Does this mean it should be 15 volts
Positive terminal or also known as terminal 15. Correct me if I'm wrong but terminal 15 is 12v when ignition on and terminal 30 is always 12v
CDI ignition coils need minimum 100v pulse and do not spark with 12v battery
An ignition coil like that one ups the voltage from 12 to 20kv
My friends has an older corvette with CDI and all the coils that are suppose to work crap out after a couple of 100 miles. All the coils have different ohms so.
If the spark plug does not spark
Does that mean coil is bad ?
Could also be a broken spark plug or the gap is too wide, or could be a broken cable but it's easy to check if the cable is broken
@@jesseycoolen4169 Did you get an answer to this question? I've tested mine and get a spark from touching the wire to body of spark plug but the spark plug isn't sparking? Does this mean something is bad or is that normal?
@@PublicWebVideos so you get a spark from the cable but not from the spark plug? Than the solution is easy, you need a new spark plug (don't forget to adjust the gap)
Hello I see lot peopel use relays for ignition coils.
Can some one describe me if I still need to use resistor or culd I use potenciometer insted?
What ralay rating I need and how to calculate resistor for ignition coil.
Me car is Opel tipical GM lay out but I use inductive trigger/4pin gm ignition module and e core type 4pin ignition coil.
So Im not shure if me ignition coil wuld work with relay or not.
Im not shure what runs it honestly alternator field wire or positive linear voltage regulator inside me dashboard Im not shure their wire harnest lay out is preaty much confuseing.
Also I have cold start problems thats why I mentioned potenciometer I dont get enough voltage to the ignition coil and the 4pin gm ignition module do not have retarding option only wacum and spring load advance .
So can some one help me please give advice how to solve this problem.
Im doing the entire wire harnest be me self and I desire wire harnest that is heavely protected against static and arcing.
I use 3 4 6 pin relays so wuld like to know where and what type of diode rating shuld I use.
And was curiuse to know If I culd use heavy gage non stranded wire insted ?
Originaly I wanted to use buss bars for ground and positive conection to avoid corrosion and futher problems with me car and make evry curcuet seperate so they do not interact with ich other.
In the past I hade flat or over charged baterrys,back feading alternator,relays interactions,dual filament bulbs and xenon bulbs interacting with me wire harnest car refuse to shut off engine,self acelerates,gives electric shock,and lot other unusual effects who are anoying.
So any one has ideas I wuld like to try out.
No.
Sorry but you need a OHM tester to test for resistance !! What your doing is testing for spark not necessarily enough spark to run an engine properly !!!
What about the condenser?
So weird, I had the same setup today (with a brand new coil) and I couldn't get spark with my makeshift spark tester (just a generic plug with an alligator clip soldered to it). Man, in the old days when I was a trained electronics guy working on cars I bench tested coils all the time this way and only ever found a few bad ones...I think I'm turning into Joe "biff" Biden...🤣
don't feel alone, I've forgotten everything I never knew about nothing, especially for cars. Going through a hard cold starting 200 6cyl. in my 64 Ranchero, One thing at a time; fuel, spark, batt., pump, etc. Looking at a mis-match with my old coil and my HEI electronic distributor but think there is a more a mis-match between my old brain and the understanding of what needs to be done, or not done!! LOL ;D
@@ronschlorff7089 Advance Timing a degree or 2 on Hard starts and see if it makes a Difference.
@@mickeycox6690 Thanks; yes, I suspect timing is the issue.
@@ronschlorff7089 Had a Dissy with a Bad Bushing drove me crazy till I figured that one out.
@@mickeycox6690 Thanks for the info, sometimes is it's the "little things" that make the difference, with cars, as you just said!! : )
therez no info that woukd place you onto a head breaking endless search forva code sequence noone has any awareness of tge only 2ay to find out is if you tried it found it and had nothing else to claim you rejected the info i sav3d before it was destroyed and its what people get whipe they tried to succeed
Haha you don't know what you're doing 😉 you don't know how to test a coil first off everything you have is right but and I'll say that word again but you have to use the temperature in between the coil negative and ground just like points distributor work no capacitor no spark. older repair manual people of the right way of testing ignition coil. And I'll add this one for free if you have a blue Violet spark that means you capacitors red or yellow capacitor not too good.
Well it would be nice for you to explain yourself other wise this is a waste of time for anyone
another vid with no talking. moving on...
