TESTING AN IGNITION COIL PACK IS EASY ~ STEP-BY-STEP
ฝัง
- เผยแพร่เมื่อ 9 ก.พ. 2024
- An ignition coil can fail, and when it does, your engine can stumble and lack power. One sure fire way to determine if your coil is faulty is to perform resistance testing of the primary and secondary circuits using a multi-meter. Today, I show you how to easily test the coil on a 2003 Ford F-150. These tests can also apply to many vehicles with coil packs just so long as you can find the specifications for your particular coil. If you can't find the specs for your coil, test it anyway and see that the readings across the primary terminals are similar to one another. Same with the secondary terminals that feed the spark plug wires. Any reading that stands out against the others indicates a coil that needs to be replaced. Remember, secondary terminals are tested in pairs. See the video to have this explained. Let's get started...Please Subscribe to my channel, Thanks.

Great way of explaining and that hat is really cool...my late dad had the exact ssame one down here in sunny South Africa and brings back fond memories🤣
Thanks for your comment. Much appreciated. Greetings from British Columbia, Canada. Glad to hear you enjoyed the video. All the best to you!
A man with a well thought out plan and a cool chapeau! Awesome instructions and explanations Craig! Awesome job Brother!
Thanks, Doug! It is so good to have confirmed that the old coil was defective. Sometimes a coil issue can be hard to pinpoint. The hat I normally only wear when driving my Lamborghini or Rolls Royce, but I wore it today in the old F-150 and it felt fine.
@@EverydayProjects 🤣
Guess i should learn to use my multi meter for things other than testing the battery 🔋
I guess if that hat works Mrs Big Son's will be getting you a couple. 🤣
They can be very handy. I don't use all the functions in my meters either but coil resistance testing can really dig down and find a problem. If you can't find the required specs for a coil see if you can compare to a new one. That will tell you its health. Be well!
@@Big_Johns What in the world 🌎
🤣🤣🤣
Great info. Your hat goes perfect with your surroundings. U-DA-MAN!!!!!
Hey, thanks!
Nicly instructed Craig . I have the exact same hat , ovcourse you look as good as I do wearing it 😉
I know, Steve...A hat like this makes a guy smarter and taller. Ha Ha Have a good one
Great information on testing the coil and a great fix too. The hat looks good, I have a very similar one and wear it the same way. Great views of the mountains
Thanks, Joseph. This coil gave me considerable trouble. I tested it several months ago and it was borderline so I thought it wasn't the problem, but given a few more months it deteriorated. Best to just swap out a coil for a known good one if in doubt. Lesson learned. I am enjoying my hat. Thanks for the comment.
How's she goin'? First off, I like the hat! We spent some time in France many years ago and they called hats like that Casquettes!! So yeah I like the casquette!! But did you notice it's feminine? Just sayin'!! Nice job replacing the coil pack and that was a good test for it too. Those Haynes Manuals were pretty popular eh. I think everyone had at least one of them for some old car they had and were trying to keep it running on a dime. BTW, I like your casquette!! BC sure does have some scenic views, even in the rain. I'm not too sure I could take all that rain though. At least here we get a break from the rain and are buried under snow!! LOL That casquette is some smart looking. I see the skip on it covers your nose and keeps the rain off it!! Pretty handy since you live in BC!! LOL Take care!!
I plan on modelling a full outfit at the end of a series of videos. There will be mechanical things in the video followed by an article of clothing modelled near the end. This hat began the series. I'll understand if you wish to skip episodes 11 and 12 when I model boxer shorts and long johns. Yes, the rain...it's pretty much all I can handle most years but the shovelling is minimal. I enjoy the casquette whether it's for girls or not. A rough, Marlboro man like me has enough solid good looks that a girly hat doesn't distract the viewers too much. Cheers!
We all have crosses to bear and you're doing a great job with yours!!@@EverydayProjects
Tune in for episodes 11 & 12. Coming soon to Everyday Projects!@@GrampiesWorkshop
Nicely done! The coils that is😆 the hat is definitely you my friend👍
The coil change made a big difference in the performance. It feels like a new engine again! And the hat....what can I say? Perfection, right! LOL
👍@@EverydayProjects
Love the hat but you don’t see many like it in Ford F-150s in Oklahoma! I’d love to retire to Victoria. Making my decision in November, post election and while I still have the autonomy to make such decisions.
Victoria BC is a lovely city-only about 350,000 but lots of parks and green space. And the climate is really mild all year. Lots to do there too with the ocean and gulf islands of Canada and USA really close., plus wilderness all up through the island. Enjoy!
@@EverydayProjects and golf courses and a beautiful view back to Washington state ! I looked at houses last time I was there and wish I had moved to secure one. Like everything else, real estate Victoria has gone up . Thanks for the video. A friend just got this truck and though we don’t really know what we’re doing, we can follow instructions.
I need to learn my multi, the hat looks better on you if its inside out and upside down lol and it really is a old man hat.
Thanks for the compliments on the hat. I often wear it backwards when I attend rock concerts to attract the chicks, but mostly, when driving around in my Rolls Royce, I like to dress the part of an English aristocrat. Multi-meters can do many things that most of us never learn fully, myself included.
I see your out in the rain again 🤭🤭🤭
Yes, Noel, it has been a rainy month but i don't let that stop me. The coil test proved that the old one was faulty. The new one works so much better. Did you see my hat at the end? Please let me know what you think of the hat. Cheers!
Nice video and explanation Craig, the hat does truly make you look swab and deboner. LoL!!!
Thanks, John. Coil resistance testing can find and sort out troublesome running issues. This truck lacked power and misfired under heavy load but didn't throw a trouble code. Hard to diagnose but I found it! Yes, Swab and Deboner was the look I was aiming for. Let's hope Renaldo doesn't get the same one.
🤣🤣🤣
What was the trouble with how the engine was working. Was it missing on both of those cylinders. Nice mountains there in the back ground. Is that an island where you showed the first mountain. Hat ? What hat ????
🤭 nice hat 👋👋👍🏻👍🏻
It was a misfire / stumble condition under heavy load that did not set a trouble code. The engine would run well but stumble on acceleration or when going up a steep hill. I changed the plugs to top of the line iridium and Bosch wires, cleaned the fuel injectors, tested fuel pressure and changed the fuel filter, started running premium fuel too... No change. Then I changed the E.G.R. valve, and changed the lower intake manifold isolation grommets! Still, the condition persisted. I was running out of options! I then changed the throttle position sensor too, but nothing fixed it. Compression tests proved strong 175 PSI + per cylinder, and there were no vacuum leaks discovered. The coil was the issue! Finally found it.
@@EverydayProjects 👍🏻👍🏻👍🏻👋👋👋
Hey how we doing, so I have a ford Taurus 2006 just replaced the spark plugs, spark wires and got a coil pack from the junk yard and I tested both old and scrap coil pack and my pins are both running 1.3 Ohms but on the scrapped one I have higher resistance than the old one but all the numbers are still below 11.5 only issue I could see with the scrapped one is a crack between 5 and 6 and this scrap one was running the car fine but then came back from a road trip now I’m losing power with code error p0352 so you think just getting a new one should hopeful solve this issues or what do you think? Also great video keep posting more like these!
Better safe than sorry. If you can afford it, just buy a new coil pack. A crack of any kind will allow moisture inside and will cause problems. Even coils with hair-line cracks should be tossed (even though they may work well for a while). Best to eliminate any doubt. Try to get a name-Brand coil like Motorcraft, Delphi, Blue streak, etc. There are so many really cheap coil packs online that are just junk. In fact, I had ordered a $25 one from Amazon for this truck and it set a code immediately and would only run when cold. Once hot, after 5 minutes driving, it would set a code and run poorly. The Delphi brand is more expensive but it works flawlessly. Try Rockauto.com they have great prices and ship fast. Good luck. Let me know how your repair goes.
@EverydayProjects I already had a purchase in I forgot the brand of the coil pack is SKP hopefully this allows me to fix the problem then save some money in case that one goes bad you?
SKP is a good aftermarket brand. You should be OK.@@jgonzo316
@EverydayProjects perfect if I got any other questions or problems would you mind me asking?
No problem.@@jgonzo316
