I send you a picture, ©2016 Aircraft Owners and Pilots Association, По какой-то причине пресса незаслуженно очернила микрозаймы в глазах общественного мнения. Part no: LBER-R. Excl. Two old Champion spark plugs failed because of internal resistor burning out (with a lot of hours on them). The thing these spark plugs had in common were that they were all Champion-brand plugs and they all measured very high resistance or even open-circuit when tested with an ohmmeter. While what happens when 10,000 volts is forced across a resistor under laboratory conditions is interesting, it is hardly relevant to resolving the problems faced by IAs, A&Ps and AEs. We switched everything to Tempest, and no troubles. Still, I can’t help but wonder why it took six years for the company to work through its grief from denial to acceptance. Going to Platinum totally changes the resistance, i.e. As a “Motörhead” I often wonder what the perfect spark gap voltage is, well in this case it is about 0.05′ across the spark plug gap and another about 0.5′ gap across the resistor! Nerheim also disassembled the resistor assemblies of a number of high-resistance Champion plugs and found that the internal resistor “slugs” were failing. Spark Plugs . Resists fouling; Superior corrosion resistance; Dependable performance and durability; Increased conductivity … Since this was a new engine (about 40 hrs since new), I called Champion and was able to talk to Kevin Gallagher, their Piston and Airframe Manager. The EI powered plugs have shown a much accelerated effect of increased resistance as compared to the mag powered plugs. who ever made it didn’t care.

Mike, can you show pictures of the old and new metal contact you’re talking about for identification purposes? https://www.youtube.com/watch?v=DERIHonZT-k They should have adopted Auburns design immediately. The lowest spark plug resistance that seems to perform the task of chopping off the front and back “tails” of the spark is about 500 - 600 ohms. St. Fort Lauderdale, FL 33309, Toll Free: 877-833-6948 No Tempest didn’t in discover anything new, they used a very old design that has been in the BG plugs I run in my Waco. By: Janet. Question for you, you mention Champion was in denial for 6 years. He said that the rep he talked too was VERY nice and accomodating and even stated that “the competition” was killing them so they are trying to regain the market. ! Aircraft ownership and maintenance, Mike Busch, Opinion, ChampionChampion AerospaceGA advocacygeneral aviationmaintenanceohmmeterownershippreventive maintenancereliabilityresistanceresistorspark plugspark plugs. You have no items in your shopping cart. ( and that bad magento point did anger me greatly, since i know how to rivet, it aint rocket science ). the OLD plugs in my car were Autolite 85’s and only measured 4k-5k each. You can be sure they will not compensate, but you can get a certain amount of satisfaction by never buying anything from Chanpion again (and recommending the same practice to all of your customers). Ask your spark plug sales man for the “as manufactured” resistance of his new spark plugs. Overall Score: 9.4 . For new plugs, we recommend 4000 ohms as the maximum acceptable value. I tested them first on the Tempest gizmo ( it is fairly quick and accurate) then because of the red light (failing), tested for the Ohms value.They were all very high. Compare them and you’l clearly see the difference. Factory plugs are copper for a reason. Spark Plug Cap - Rubber Waterproof - Nut Terminal Red. $9.71 $ 9. In: Best Vacuum Cleaner. We also share information about your use of our site with our advertising and analytics partners. Eventually, the ground electrodes became so thin or the center electrode became so elliptical that the plug had to be retired from service. Meanwhile, the Champion field reps continued to insist to anyone who would listen that claims of resistor problems in Champion spark plugs were false and that the ohmmeter test was meaningless. max’s You Tube video is worth watching Choose your next Champion from the range of plugs … In February 2013, they issued a Tempest Tech Tip titled “The Right Way to Check Spark Plug Resistors,” started selling a fancy spark plug resistance tester, and launched a big “What’s Your Resistance” advertising campaign in the general aviation print media. Military Specification MIL-S-7886 provides guidance for aviation spark plug manufacturers. Center wire resistance values of any resistor type spark plug shall be as specified in the manufacturer’s drawings or specifications. 1983 Saratoga Turbo, Lycoming TSIO-540-S1AD engine.

I eventually replaced one of my Slick mags to finally clear up the starting problem altogether. Tulsa, OK 74115 Here’s what I know. resistance throughout the plug’s service life. First annual, 117 hours, found 1 cracked fine wire and two massives failed the Ohm check, replaced. Well, I always seem to have a contrary view, so I might as well continue the tradition. Last fall, during a plug “bomb” test, two of the plugs didn’t pass. one set of plugs is not statistically significant. FREE Shipping. Simply look at the metal contact located at the bottom of the “cigarette well” on the harness end of the plug. I believe that Champion had to change because the Tempest advertising barrage got the herd to scampering. To contact them, click here. 5746 E Apache St. 70. Further, they stated that the proper way to test a spark plug is on a spark plug testing machine (so-called “bomb tester”), and claimed that if a plug functions well during a bomb test, it should function well in the airplane. i guess you can say spark plugs are a fault tolerant design. Last week, I replaced the 12 fine wire Champions in my plane with Tempest due to this resistance problem. Resistance values differ between manufacturers. If the resistance was too high, the plug would fire weakly, resulting in engine roughness, hard starting, excessive mag drops, and (if the resistance was high enough) arc-over damage to the magneto and/or harness. Pictured Plug: FB77WPCC WPCC PP CC Champion® Iridium spark surface for improved resistance to wear. The spit really hit the fan when Champion’s primary competitor in the aviation spark plug space, Aero Accessories, Inc., launched a marketing campaign to promote sales of its Tempest-brand aviation spark plugs by highlighting the resistance issue. 4. Compare Compare Now $2.39 USD Open Delay. After all, the plugs did cost close to $1200. N III This robs available voltage at the spark plug gap, as it "leaks" through the low resistance carbon deposits to the ground, resulting in a weak spark. Add to Basket More Info. Experimentation showed that a resistance between 1K and 4K ohms turned out to be a good compromise between ignition performance and electrode longevity. It was ridiculous! In the meantime, we’re all stuck with $400+ per engine in defective Champion plugs until we have to come up with spare $ to buy Tempests. The reason was that each time the plug fired, a significant quantity of metal was eroded from the electrodes. Resistance values were 20,000 ohms or more for some of the plugs. Tune up your outdoor equipment with our Champion small engine spark plugs. additionally, the electronic ignition driven plugs all have reduced life. This replacement spark … These Champions had just a few hundred hours on them. Tax: £7.06 . We are not Champion Spark Plugs USA. One very unfortunate scenario could happen if one spark plug is bad (open resistor) and the next in the firing sequence is “good” – the arc could conceivably jump inside the magneto to the next cylinder in the firing sequence! Replacement … Take an OHM Meter and measure the resistance value from the connection in the bottom of the barrel to the clean center electrode at the firing end, electrode must be bare metal. Most reports Tempest receives about rough running engines associated with high spark plug resistance involve values of 7000 ohms or more. Here are the old and new cutaway diagrams. The cause-and-effect relationship was pretty obvious. As I write this, it’s still too early to tell whether Champion’s quiet resistor redesign will cure the drifting resistance problem, but my best guess is that it will. Products Automotive Filters Lighting Spark Plugs Batteries. We were seeing numerous cases of Champion spark plugs that were causing bad mag drops, rough running and hard starting even though they looked fine and their electrodes weren’t worn anywhere near the retirement threshold. What experts didn't like . about 125 hours after a factory overhaul my Lyc IO-360 was grounded due to rough running. Thanks Mike for the article. Tax: £4.75 Incl. Champion standard spark plugs remain the best option for vintage cars, motorcycles and garden equipment. Max Nerheim discussed his high-voltage test findings with Kevin Gallagher, Manger of Piston and Airframe at Champion Aerospace, and Gallagher acknowledged that Champion was looking into the issue with the resistor increasing in impedance, but did not have it resolved yet. Search spark plug cross reference . I fly a turbo-normalized Cessna 177RG with the STC’d IO-390. I just bought a box of Tempest plugs from AC Spruce. understood and my best wishes as well, of course. I shared my findings with him on my 2 year old Champion plugs that I had pulled out of my Mooney, which all showed the high resistance and some internal corrosion. Both of these represent good resistance values right in the sweet spot. So far as I have been able to tell, they didn’t even issue a press release. Tax: £1.71 . Also, he sent detailed test reports of the plugs I returned, along with pics of the test process and procedure (the plugs passed on their system).

Copper Spark Plugs. If resistance increases significantly after the plug is manufactured, what was once a good plug becomes a bad plug. These plugs came from cyls 2 and 3, which run hottest in the engine. Spark plug manufacturers found that they could extend the useful life of their plugs by adding an internal resistor to limit the current of the spark that jumps across the electrodes. Resistance checks DO NOT replace the familiar spark plug cleaner/pressure bomb test box that actually sparks the plugs under air pressure. I checked with a number of A&P mechanics and they verified that the latest Champion spark plugs they ordered do indeed have the new design. A new Champion plug will have a value of 800 to 1200 OHMS. ITEM #CHA121. Arnold First Fire FF-10 Replacement Spark Plug. Here, for example, is a set of 12 Champion plugs removed for cleaning and gapping from a Cirrus SR22 by a shop in South Florida: Notice that only two of these 12 plugs measured less than 5K ohms, and one of those had to be rejected because its nose core insulator was cracked (a separate issue affecting only Champion fine-wire spark plugs, and unrelated to the resistor issue that affected all Champion plugs). If you call them to send them in they may replace them all for you. Also, the wire wound conductor never changes resistance. I’ll be looking for the new non slotted types. The equipment works all the time, spark testing mirror breaks/scores often, you need to change it every now and than! NGK BKR5EGP G-Power Spark Plug, 4-Pack. I’m not putting those Champions in anything !! But I would not jump to the conclusion that Tempest has discovered some previously unknown secret about spark plugs, except maybe how to sell them. Just today I found 3 out of 8 that were bad with the resistance check. They cleaned and replaced all the resistors, replaced a couple plugs that had other defects, turned them around and sent them back to him in a week and free of charge! From innovation aviation technology to a tradition of motorsports dominance, the Champion brand has been a part of product development in every type of engine.

DENSO PK20TT PLATINUM … SMALL ENGINE Spark PLugs. You’ll save time and money by not putting high resistance plugs in an engine just to have to take them out when you find that they’re causing the engine to run roughly. Of course, this “company line” from Champion didn’t agree with our experience. Conditions on a blazing hot or freezing cold ramp arent laboratory conditions. Champion Spark Plug Company’s Engineering Manual gives the nominal value for their resistor type of aviation spark plugs as 1000 - 1500 ohms (no +/- value is shown, but minus 400 and plus 1000 probably wouldn’t be unreasonable). Advanced rectangular bar design provides improved ignitability and longer life. I operated the 182 for 6 years which included 3 years of daily commuting between Olympia and Seattle, on the same set of Champion fine wire plugs and Slick magnetos. Brad M. June 8, 2018. And I’ve had nothing but issues with Chapion spark plugs. They followed through and plugs are installed. Resistor-drift is not a problem with the Tempest’s “fired in” resistor design. This can be seen in a Scanning Electron Microscope, little holes in the walls of the resistor,more holes equal more resistence.I sent the SEM pictures to Champion Research they replaced all my plugs! Perform a spark plug wire resistance test. My current airplane, a Piper Pacer, is much the same story except I only have 1000 hours on the plugs and mags at this point using the same operation and maintenance practices.
