Learn how to easily test a spark plug to rule it out as the cause of your engine problem. A simple and highly effective method(when done properly) that I've always used to confirm if a spark plug is/is not the cause of engine starting and/or performance problems. Why run to the store and buy a new spark plug as a gamble, which may not be inexpensive, when you can verify if the plug is the problem using your digital multimeter. Save time and money! No method is 100%, but this method has been proven to work the great majority of the time.
I decided to upload this video when I discovered that not too many people knew about this simple, effective spark plug test.

**ATTENTION: If you have any concerns about removing a hot spark plug from an aluminum head, then you can also remove the plug when it's cool and heat it up in a toaster oven to 300 Deg F to perform the "hot" test. Never file down or sand Platinum/Iridium tipped plugs. "Hotter" spark plugs have a LONGER ceramic nose, and "Colder" spark plugs have a SHORTER ceramic nose. Using a slightly hotter plug can prevent fouling if your rings are worn and allowing excessive oil to accumulate on the spark plug's electrode.

Lawnmowers now use suppression plugs due to the Delphi fuel injection systems on Kohler and Vanguard. Specifically the NGK bpr4es and bprm4es as well the 5’s too. If not the 5 volt reference in the OBC will act wonky and cause problems in the injectors as well as the coils. Just a little info on the subject :)

Quick Tip: For continuity testing or even resistance you should always try an initial test by touching the two leads together first. Its not unheard of to have bad leads or connection to multi meter that may make you think something is wrong with the spark plug for example. Just good practice.

When I had the pleasure of working with a great racing mechanic Mario Deliotti I showed him that a plug I had out of my Alfa Romeo sparked perfectly well out on top of the engine. He laughed at me, called me something in Italian, and told me to put it the spark plug tester. I did and it sparked ok looking through the inspection window. Now I turned up the air pressure ( the tester connected to the shop air line) and at 80 psi plus it hardly sparked at all. Put a new plug in the tester and that lit up like a Christmas tree at any pressure. As an electronics engineer I have never understood why this should be but it taught me that a low voltage meter test at atmospheric pressure is worthless. Don’t waste your time just replace the plug.

Yes that is correct, the higher the air pressure, the harder a spark has to work to punch through it. However you do not need anything as elaborate as a pressure chamber to test spark plugs "under pressure". Simply open the electrode gap to one quarter inch and it will simulate it for you. If you get a good spark like that its good to go.

I know you are dealing more with the electrical side of testing, but, don't forget to also look for signs of leaking gases around the insulator and signs of plasma staining on the insulator. Both are good indicators of ignition faults/wear and tear. I am hooked on your videos, great job.

I can't speak for today but years ago Champion plugs came with a "booster gap" built into the internal connection from boot to tip. So the continuity check would read open circuit. The booster gap was there to make sure the available voltage was higher when the spark energy actually hit the tip. The idea was to be able to get a fast voltage rise at the tip despite some leakage to ground on the tip of the insulator.

I used the information on this video to check a spark plug on a snow blower that was not starting and had been used once or twice. The 2nd measurement on the existing plug, from tip to the body of the plug, was not showing the results that were demonstrated in the video. I sprayed the other end where the spark should be coming and got inconsistent readings. I spent $1.90 to replace the plug, and the snow blower started immediately. Thanks for the service.

Neat stuff. Every mechanic should have a heat gun (I've scored a few at yard sales so I can scatter them around the shop) and will try your method before and after heating up some spark plugs. A propane torch would also work and handheld thermometers are dirt cheap. To quick check plugs I shoved the end of a gas grill piezo igniter into an angled spark plug boot then ran some solid copper household ground wire around the shell so the ground contact on the igniter has a path to ground. (It normally grounds thru the gas grill body.) Wrap with electrical tape and you're done. Great for detailed arc observation without running an engine.

First off, this is a valuable test. Over the years I've seen too many outboard and power equipment owners automatically throw new plugs into a motor expecting that to be the miracle cure. Ninety percent of the time, it isn't. But, I never thought of testing the electrical resistance of the center electrode, which would be the only real reason for failure outside of wear or breakage of the insulator.

Engines usually miss at idle or under acceleration/under load. Can either be a faulty spark plug/high tension lead & or coil pack. Some engines dont have high tension leads, but a coil pack for each spark plug. When you accelerate/more power, throttle butterfly opens increasing air supply into motor. Fuel injectors stay open longer allowing more fuel into motor. Therefore the ignition coil increases voltage for stronger spark under more demanding internal engine conditions. You can also test each individual high tension lead using ohms/resistance scale on your multi meter for either open circuit or very high resistance reading. As a rule of thumb, high tension leads should have anywhere between 7000 to 12000 ohms "per foot lenght" of high tension lead, (7K to 12 K scale). You can also test your ignition coil pack in a rather crude way, like a bush mechanic without any tools. Start your engine, let the motor reach normal operating temperature. Remove nut or bolt that secures each coil pack to the engine. With the motor idling, gently lift the coil pack slightly off one spark plug at a time so you can hear the sound of the spark jumping from the coil pack to the spark plug. Dont lift the coil pack too high off the spark plug. You will hear a specific normal spark rhythum. Your listening for an an irregular/abnormal spark sounding rythum. That will indicate a faulty coil pack. This test is limited to engines you can access the coil packs individually whilst motor is operational. Unfortunately some engines, wont permit this limited test. Be sure to wear rubber gloves & tools that are insulated. Cheers from 🇦🇺

One small point to contend... I worked in auto part stores for over 15 years and have learned from reading the indexes that the reach of the ceramic on the combustion side of the plug is what controls the heat range. when the tip is recessed (protected from heat) it will be a cold plug. When the tip is projected into the combustion chamber, you will have more exposure to heat , and more ceramic material to hold the heat. Other than that your video is correct!

Actually we use to check the resistance at the end of the Seal line during the manufacturing process. We also did dielectric test to ensure the bisque had no pin holes. We made millions of every brand plug on the market. No one brand was different from the others. I know some guy just crapped his pants to hear this, but Champion, Atlas, Prestolite, Autolite, Shell, Sears and others were made exactly the same with the same materials.

Sometimes even part of the production line is the same... same workers under the same roof, etc. There are differences, but not where most people think. Surely not in the "brand". ;-) BTW the retail price is the most visible side of the story. LOL :-)

Well yeah, most products are marketed under various brand names even though they are manufactured by the exact same process. They all test the same, and operate the same. However, the issue occurs when the "Brand Name" is applied to the spark plug. The moment that the brand name "Champion" is imprinted on a sparkplug, its reliability is adversely affected.

As a Jet Mechanic I am glad you pointed out that the electrode could have cracks that and I might add that sometimes the cracks are not noticeable when the plug is cold but when the plug heats up the electrodes expand and causes a lack of Spark. It's funny watching this video I just went out and bought a tester this afternoon to test my Spark plugs in my new jet ski that I purchased that is not running and three mechanics have worked on and can't figure out why it wasn't running so I picked it up for 15,000 pesos in the Philippines with a trailer that's worth 25,000 pesos LOL because they couldn't get it running The motor itself according to the Spark plugs and lack of oil runs properly or did when it shut down so it hasto be a spark issue or electronics issue. Either way in a short period of time I will have ruled out any breaks in the electronic harness with the tester I purchased this afternoon and from there it can only be power pack which is as you note a sealed unit and must be replaced as a unit as a last resort. Absolutely ridiculous price of the electronic power pack in a jet ski GSX limited-edition SEA DO,,, $1000 plus shipping but it will be cheap if that corrects the problem considering I just purchased a jet ski worth 4000 American dollars for about $350 with a trailer that's worth more than what I paid for the unit and the trailer itself.

LOL . I would do a continuity test on every wire from point A to point B. My jet ski had one wire that corroded inside the insulation. Luckily I found it.

@hoodwinkedbyanangelmichaelfazi 10 жыл бұрын

electronicsNmore that is precisely why I bought the meter a.k.a. to test each and every individual wire in every part of the harness From A to B. All it takes is a small crack in the insulation in a little bit of salt water and it will corrode internally as you well know. Plus if I showed you the video I made of the harness you would see that the three so-called mechanics peeled off some insulation about 3/8 of an inch long and twisted the wires together without cleaning the wire itself prior to twisting it which means it may not have any continuity whatsoever because they twisted oxidized wires together not knowing anything about oxidation because they are not mechanics in the true sense of the word. I however went out and purchased a nice little wire brush some flux 40/60 solder which is still legal in the Philippines I'm the properly spliced them together laterally like this supposed to be. Went to 12 stores in the last week looking for some heat shrink... and no one even knows what it is here in the Philippines so I purchased some 1/8 inch diameter clear hose used fish tank filters and after the joints are soldered I will put some black high heat silicone over the wire and slipped the tubing over that which I'm sure will be sufficient to keep it from getting wet... The machine ran perfectly until it was left unattended for a few months and when the man went to start it again it just didn't start so probably the electronics is not the issue and probably more like one of the three fuses I found that were blown?? Do you think? LOL We shall see,,, it's the 1494 in. cubic centimeter engine and if you look at it in the video I make this week you will say it looks like it just came out of the factory however when you look at all the cannon plugs you can see that the high-quality brass male and females are completely oxidized. So I will take my little files and drill bits and polish them up in an out. Between that and a proper soldering job and testing the wires themselves I should have ignition when I'm done with that. There are some heat sensors on the top of each head and also in the exhaust loop and I'm not sure if they will shut the motor down what I will check those as well and the tubing that goes to the sensors. This is my first jet ski and it didn't come with a service manual so I will look online I'm sure it's there but only purchase this machine three days ago and this is not my livelihood is now my hobby which I devote 10 hours a day to anyway LOL If I have any questions I will be sure to bring them up on one of your pages after I do some research on your videos if it is not covered somewhere that I can find? If I don't I still believe it is something a lot simpler than the power pack and that is my last resort and you are right it's highway robbery. Okay my friend thank you for returning my comment and best wishes to you from one mechanic to another. Michael

HoodwinkedbyanAngel Michael Fazio I am so glad I came across this video and y’alls ‘troubles’ after acquiring these sea-doos. I myself have been given one and it too was a ‘it ran perfectly when I shut it off but will no longer start’ scenario. 👍👍 I say “perfect!” as it too does not have any spark. Seeing as I love electronic/electrical type work I welcome the challenge...and hey, for the price?(free) I am ahead of the game already if it actually does need a part or two. Any recommendations where I should look first on one of these beasts? I have done two stroke ski-doos of all types so that part is pretty familiar, just not their watercraft. You say the ‘power block’ can/may be an issue?..I’m guessing it’s to do with leaking water internally causing it’s many quirks. Let me leave y’all with one recommendation when cleaning up corroded wires....you will thank me for this later..trust me. Whenever/where ever you have corroded wires needing to be reconnected and you find ‘sanding’ them or ‘scraping’ them with a blade don’t quite do it, try dipping them in muriatic acid from the hardware store. This product is used for cleaning and etching concrete in pools etc. NOW BE BERY CAREFUL WITH THIS STUFF!!! IT IS HIGHLY CORROSIVE AND EXTREMELY TOXIC!! USE IT WHERE THERE IS EXCELLENT VENTILATION AND KEEP CLEAN CLEAR WATER NEARBY TO NEUTRALIZE IT WHEN DONE. It takes only 10-20 seconds of dunking this in the acid and it’s done..clean. Quickly rinse it off with the clean water and dry it off completely. Do give it a few passes with the emery cloth or sand paper to get that brilliant copper shine back which makes it the easiest to solder. I know the good heat shrink is the best but I see not always available. Check for a product called ‘liquid tape’. It’s black in colour and smells a lot like contact cement. (😮 💡 😮☝️👍...did the lightbulb just come on? 👍😉) ...I believe if there is no liquid tape available, you may be able to improvise with the contact cement...I’ll leave that up to y’all to figure out 💡😉🤞👍 Spread this liberally on and over the newly soldered connection right onto the wire’s insulation so no water/moisture can penetrate it. Cover that with electrical tape to help stop any possible abrasions that may occur. Thank you kindly for any tips you may have for me and I hope mine will come in handy for you. With any luck it won’t take me long to repair it as up here in northern Canada, our ‘Sea-doo season’ is already awfully short as it is..from October to June the ice makes for some powerfully rough and cold boating on a sea-doo anyway. 😆😆😁😄🤣 All the best from a fellow mech. and watercraft enthusiast. 👋👋👋

@RussellBooth1977 8 жыл бұрын

Well , I have fully rebuilt a Stihl hedge trimmer due to low compression & fitted a new carby due to having a leaking main nozzle check valve, the ignition coil was also replaced due to having no spark. The spark plug isn't NGK but their electrode resistance is 5 K ohms for their resistor type spark plugs,the plug I have measures 9 K ohms which I am told is too higher resistance which can cause hard starting & rough running , in my case I have a no start issue meaning that despite the spark plug having spark when removed from the spark plug hole there may not be enough voltage at the electrode to fire the air/fuel mixture in the engine. While the spark plug ran a Briggs & Stratton 4 stroke lawn mower I noticed the motor was harder to start & didn't run as smooth (surged) at medium to low speed (idle) ,actually it stalled at idle with that spark plug. NGK suggests a maximum of 5 K ohms from the spark plug terminal to the centre electrode,I am off to the auto parts store tomorrow to see if they can supply me with a suitable spark plug.

In the past I measured the resistance of the new plug compared to the resistance of the old plug and gave the plugs a tolerance of 20% . That is how electronic resistors are ; with silver standard being 10% and gold standard being 20% . The plugs I use are cheap and when my cars computer starts tripping codes for bad plugs they are usually around 20% .

Doug, thank you for your concise and informational video. A couple of questions...is it possible to test plug for spark while it is still in? Also, my specific application involves a non-working leaf blower, therfore i cannot test a "hot" plug; does that matter? My guess is that there are lots of people who are testing their plug because it can't "get" hot! Thanks again. dc

The type/brand of plug can indeed matter. I (and some friends) have only ever had good luck with NGK "V-power" plugs in our older cars (mostly V-8's). They last longer/run better,in my (our) experience. Some newer engines can be picky about the brand of plug as well. (I've even had good success using the NGK's in place of platinum plugs,in some newer engines.)

@electronicsNmore 10 жыл бұрын

Hi, I never stated different types/brands of plugs did not matter, what I did say is the procedure outlined in this video works on all plugs. In my experience, using split fire / bosch platinum / NGK / autolite, I noticed no difference of performance with my personal water craft, cars, mowers, etc. I can probably switch out a plug that someone insists works better(without them knowing), and they would likely notice nothing. Thanks For Watching!

StormieinFlorida You might want to check the lambda sensor if your truck as one (or two). They tend to be forgotten and performance degrades with time.There's enough videos around to give you some insight on how to check it with a multimeter. Good luck ;-)

I see you talk about the resistor in this video as well. The resistor is to stop capacitance after firing of the spark plug. As the ignition system operates, the shielding in the plug wires builds up an electrical capacitance, ( just like a capacitor does). Once this capacitance is so strong, it'll jump the spark plug gap, this isn't good, so they build a resistor into the plug to bleed this stored electrical charge of slowly so that it does not jump the plug gap, and ware out the electrode tip prematurely. It can also lead to pre ignition. The electrically induced noise that you hear over your cars speakers is caused by the alternator frequency change when the capacitor goes bad in the alternator. The capacitor is an electric filter in the alternator, it performs the same job that the capacitor performs in an aircraft magneto p lead, it acts as a filter to filter out electrically induced radio noise. I'm not arguing, I'm just setting the info straight.

Sometime a plug can make a spark on the chassis and not in the cylinder head, its caused by the pressure, its a big factor in plug spark capability, and fooled plug can some time be recovered by burning the tips after cleaning it out with gas
