low resistance spark plug wires

As to your copper wires. Plug Wires, Taylor,accel,magnecor,and Msd Wires.

Heat damage Engine heat can burn wire insulation and boots. We encourage you to consult with a certified technician or mechanic if you have specific questions or concerns relating to any of the topics covered herein.Under no circumstances will we be liable for any loss or damage caused by your reliance on any content. Solid Core Wires: You cannot run Solid Core Spark Plug Wires with an MSD Ignition Control. A suppression style or spiral wound spark plug wire MUST be used. 4wd trophy truck proformance transfer case, coast drive side ring gear dana 80 ifs dana 60 ifs, ifs irs diff oil cooler oil viscosity ultra 4 rock, narrow ifs differential dana 80 dana 60 ifs profor, turbowerx mini exa oil flow rates failure. Advertising - I suggested to Kevin that I thought the longer leads running to the front cylinders could have a much greater resistance than the shorter leads (Half the length) that feed the rear cylinders and that the longer leads are resulting in poor spark at low revs, but could be working ok at higher revs. spark plugs you get better MPG and more power. It all sounds kewl, but no. JavaScript is disabled. In addition, the engine light coming on or visible damange to the cables can be signs of a failing wire. We checked the ECU parameters, Air Fuel Ratio, Computer Settings, we changed coils, checked our ignition wiring, checked our fuel pressures, checked compression we checked everything and found nothing. Having solid wires means there is more likely to be a high-voltage oscillation jammed back into the Pertronix module. Using silicone lubricant spray, I snaked the wires back thru the conduit to the distributor. Crank the engine and check for a good spark at the spark tester gap.. If problem is low tension circuit, I would suggest to put the points back and see if there is spark. Wire insulation thats damaged by head can allow voltage to jump to the ground rather than jumping the gap at the bottom of the spark plug. Some other voltages were on the wire the meter was not picking up. As it unravelled it revealed a stiff inner core that felt very different to the rubber feeling core that I found in my questionable plug lead. Ahhhthanks for the link. I believe should not is the right expression. As pointed out you can get the resistance elsewhere - for example the brush in your dist. ARE "LOW RESISTANCE" SPARK PLUG LEADS ALL THE SAME? If a spark is present, the problem is probably in the distributor cap, rotor or spark plug wires.

The suppression wires do an excellent job of controlling the EMI with no degradation to the ignition performance. That does not mean 0 resistance as you have will not work- it obviously does. My question is, is that right? Its not necessarily about making sure the ignition doesnt interfere with your radio. Note: Try to avoid direct contact with metal parts of the vehicle when checking for shorts., Remove a spark plug wire from any plug. Weak sparks are orange or red and may be hard to see in daylight. It is unlikely all 6 wires failed. And youll find the same recommendations on most electronic ignitions, including EDIS. If no spark, problem is low tension circuit and either 12 Volt wiring to Pertronix is not provding 12 Volts or failure of Pertronix, or Pertronix gap changed because screw holding Pertronix to plate loose and Pertronix gap to magnet changed (unlikely). Quality of the wires should a prime consideration. The brand new leads I was running on the Small Block were indeed new, but a Brand and Type I had never used before. Much to my surprise (After spending quite a few of my Race $$ on this high quality set of Race Leads), the plug lead I was holding in my hand had an inner core that I can only describe as a tiny 2.5mm black flexible rubber o-ring stretched out straight. For a better experience, please enable JavaScript in your browser before proceeding. Should I be able to get continuity and a resistance reading from the distributor end of the wire to the spark plug connection? Most distributor caps sold for Jaguars today have a brush that has 5000 ohms. What are your Spark Plug Lead Conductors made of? cap is probably about 5000 ohms. Why use them?

So, in this case, high series resistance is a good thing, high voltage is a good thing, and less current is a good thing. Heres a articular written by our friends at Hot Rod Network showing pictures of the different wires. The failures took several weeks after a new module to fail. The coil creates thousands of volts that it supplys to the spark plugs via the plug wires. The ignition coil builds voltage until the gap is ionized (jumped across). Be sure to first check spark plug wires for visual damage. I have a Pertronix in my car so I have its install instructions (somewhere!) I spoke with a tech (Frank) at Pertronix, who informed me that the Pertronix ignitor is not compatible with solid core spark plug wires. We took the Truck out Testing and the engine screamed at high revs, ran for hours of testing and everyone was again happy. To prepare the new wires, I cut them to length and stripped about 3/8 to 1/2" of the insulation to leave the carbon core exposed.

The failure is NOT in the wires, it is in the Pertronix itself. Lowest is best. The MSD 8.5mm Super Conductor Plug Wire is available in Universal Kits and Bulk Lengths. Like Geo Ive run many miles with a Pertronix ignition and copper wires. ng Demon coil and low resistance spark plug wires. None. This winding procedure, combined with a Ferro-magnetic impregnated centre core, produces an extremely effective Electro Magnetic Interference (EMI) "choke". After many months of annoying black spark plugs, Proformance Motorsport recently changed our Spark Plug Leads to the Awesome MSD 8.5mm Super Conductor Leads. its not likely caused by his choice of solid wire. Our problems started after our new engine was bolted in our truck and the engine was run at idle a few times to manoeuvre our race truck inside our race shop or when the beast was loaded on or off our race car transporter. As others have stated, including you, there are sources of resistance in the secondary system. On another tangent, the OP indicates hes planning on using his new Pertronix carbon core/spiral-wound plug wires with his Champion spark plug terminals. Not all copper wires will cause failures. Perhaps the resistance of the Champion plug connectors saved me. But, IMO, it does not matter whether the resistance is in the wire or the spark plug end. Once this happens, voltage can jump to ground instead of reaching the spark plug. My English teacher Miss Handley would point out that you can, but you may not. Higher resistance in series means less current for a given voltage magnitude - ohms law, so Bradlybob is correct.

So, whats the verdict? Lower resistance plugs will result in LOWER firing voltage and lessened spark energy. Then it hit me! But I also noticed when I got the meter lead near the primary coil wire, I noticed a small spark jumping. The reason for the high resistance plug wires and plugs is to keep current to a minimum. I also have many brake components that came with warnings of the dangers of DOT5 - which I also ignored. Problem with nonshielded type wires and low resistance plugs is they create higher EMF `s(electromagnetic fields) and while modern ignition systems are mildly shielded they can cause havoc with the computers reading millivolt and milliamp signals and can produce "dirty" power throughout the electrics. Which Is Better? You may be measuring them incorrectly with your ohmmeter. Show me why that is so if it is. TurboWerx Exa Oil Pump Review - Should you buy one? It obviously is physically possible and it is also possible to disobey instructions. Repro Champion ends have also created a huge number of problems for many people over the years.

DO NOT USE SOLID CORE (COPPER CORE OR STAINLESS STEEL CORE) SPARK PLUG WIRE WITH ANY ELECTRONIC IGNITION SYSTEM, https://pitstopusa.com/p-4155-msd-ignition-tech.html. I remember reading an article on the Magnecore site saying that resistance is not the MOST important item to consider when choosing plug wires. If you are running original type points distrubutor you want as close to zero resistance as possible. Anybody that knows me will understand my absolute passion to get to the bottom of something and I just had to know what was wrong with this questionable lead (And the other three leads that were are causing the my spark plugs to foul up with carbon. There should be a regular spark as you crank. Turns out, solid core wires were indeed installed, so I purchased a set of Flame-Thrower low resistance wires from Pertronix. (Dont you hate it when one of your mates pops around and solves your 3-month problem in a few seconds)? When in the wire, it varies with the length. But for best spark, have some resistance. Terry- I believe you are asking the same question again- why would copper wires possibly cause a Pertronic failure- show me. I can not show you, but I did explain how the secondary circuit and the primary are combined, not separate as you implied. Resistance is not the most important detail to be concerned with when choosing spark plug wires. Even with the fouled spark plug, the dead cylinder that was fitted with the MSD Lead fitted came back to life and the exhaust temp of that cylinder came back tonormal. I had a few arguments with one race shop owner who kept asking me Why do you specifically want an MSD leads when my Brand XXX Super Duper Race Lead are even better? He wanted to show me chart after chart to explain to me that the resistance per foot of his Brand XXX leads were lower than the Resistance Per Foot if the MSD leads I had asked for. I investigated further and pulled at the tiny wire strands. If there is a regular spark, problem is rotor or distributor cap. A good friend of mine Kevin happened to be visiting our race shop whilst I was again busy changing my spark plugs (for the 6th time in a few short months) and asked me if the problem could be a spark plug lead. The voltages read fine, 14 volts alternator voltage. This is necessary due to the aging of the spark plug wires from exposure to extreme temperatures (hot and cold), engine chemicals (oil, grease, coolant, etc.) RFI is inportant to me due to the fast that I compete in DBdrag racing and in usac(SQ). Not sure what I am doing wrong here. Terry, follow the secondary circuit after it goes through the spark plug and to the engine ground. and can tell you what the gap to rotor magnet should be. With lower res. The issue is that most primary wiring now has many thousands of ohms resistance for modern highly computerized cars and .that is the point I am making. A PO had installed a Pertronix ignitor in my 65 S1 4.2l distributor. Contact Us - Simply attach or hold a meter probe on each end of the cable and read the total resistance on the meter. http://www.pertronix.com.au/ignitor3.html. Is this a good combination that listers have had success with? DO NOT USE SOLID CORE WRES WITH ELECTRONIC IGNITION!!

100 ohms is a very very very small resistanceit will be there. I have included some more Info re the MSD Super Conductor leads from the MSD Website below: The MSD 8.5mm Super Conductor Wire is "the" performance wire.Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire; incredibly low resistance without electronic interference! If a spark jumps from a plug wire to the test light at any point, this is an indication that the insulation has broken down, and the spark plug wire should be replaced. Repeatedly. My first thought was the primary circuit was for some reason drawing too much current. That is the lowest resistance of any helically wound wire. Keep in mind PerTronix ignitions need carbon-suppression, or spiral-wound wire: ULTRA NARROW DIFFERENTIALS - TECHNICAL VIDEO, Reverse Drive Quick Change Transfer Case with Under Drive for 4WD Trophy Trucks, COAST TO COAST - RUNNING DIFFS BACKWARDS OR UPSIDE DOWN. Do the Pertronix wires have some kind of connector already attached to the distributor end of the wire? Later on, we had the same failure on other engines that had point systems converted to Pertronix. Note the failures were not immediate. Modifications specific to the MINI Cooper (R50). Do contact me via Private Message if you want to discuss more. Nick. Now onto the high tension wires Ive used both resistor plugs and non resistor plugs, all without issue. If you have lower resistance wires then you will have higher current flow through the wires.

I changed the plugs one more time and when we took the truck for another test session. This EMI can create confusion with electronics and ultimately damage them. However, some OEMs have recommended different maximum resistances. Tom. Pertronix says no solid core wire, but they dont tell you why. He would replace the module, then about a month later, the module would fail. Best advise about them is not to use them, and particularly if you are not entering JCNA concours with the car. All rights reserved. More current, more heat and induced noise in the rest of the electrical system. If you do not understand it, here is a link to a discussion a while back: Solid Core wires do not suppress any Electro Magnetic Interference (EMI) which will interfere with electronics or rev limiters on your vehicle. If you did not see a spark, remove the coil wire from the distributor cap. I feel obliged to take the stairs, And why would they, as the Pertronix Ignitor is not connected to the ignition wires, it just triggers the coil to work, Yes but, the load on the ignition coil reflects back through the coil to the the primary winding (think transformer) to the Pertronics igniter. I would have NEVER believed that a set of plug leads could have caused so much frustration and so many headaches to my team. Scott Bryce - Owner Proformance Motorsport. Its possible they have changed the internal components, so it will fail if you use them, but I suspect its because they want you to be good citizens. Turns but no fire! A damaged boot can impede proper spark plug wire seating and performance. Even with the fouled plugs, the engine ran fine. The issue in the post was a narrow one - why did his ignition fail? Besides, everyone knows the red ones are "faster". What is the purpose or application of solid wires? Spark plug ends, rotors, distributor caps and yes buttons, etc. A proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears. .Doctor D has said that the Jeep is a non D.I.S. Needless to say, I was very impressed with the MSD Lead, when compared to the rubbish lead that I was holding in my other hand. The high resistance of the wires keeps the actual current flow very low but still presents 1000's of volts of voltage potential to the spark plug gap.

Tom. Use tab to navigate through the menu items. With the engine running, move the test light along the length of each spark plug wire. Before you do anything, I suggest you track down WHERE the spark failure you had has come from. My boat uses the old style points and condenser system. You want the LEAST resistance possibleso you can have more electric spark energy. I know that Spark Plug Lead manufacturers advertise graphite core, carbon core, low resistance leads etc, but come on, whilst the material that this core did indeed have a low resistance (As stated by the manufacturer), the inner core was clearly manufactured from was flexible like rubber substance and was OBVIOUSLY the cause of my poor spark, my engine problems and my frustration. Differences in resistance wire-to-wire do not matter one bit. The copper core also allows the copper washer end of the wires (on a distributor with screw-in connectors) to be solder which makes for a neat & secure connection. Manuf. But one customer started to have repeated failures. The VAST majority of electronic ignitions will be damaged by use of solid core, non-resistance wires. Given that you did have a failure, I suggest you check the distributor cap contacts for continuity (ie from inside of cap to outside with ohm meter.

Spark plug wires most definitely will affect the primary circuit. At the high tension wire to spark plug connection, you need to strip away enough insulation so that you can fold back the core over the wire insulation so that when you crimp the connector to the wire, it touches the core fibre. This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. Heres a guide for installing new wires if its time for replacements.. If I am understanding how you are measuring, yes you should have resistance, often about 1000 ohms per foot, but it does depend on your wire. Well if it is a true DIS then the best/longest lasting plug would be a dual tip platinum.Because the arc jumps both ways and DIS fire twice as often.A true dual tip Iridium would be even better as it is a more durable metal and has a lower resistance than Platinum but it would be pretty expensive if they ever made such a beast.I`m pretty sure AC and Autolite make a reasonably priced dual tip with the extended electrode design that the 4.0l likes.Dr is right the computer is looking for missfires so if thats a problem it should show up.I honestly doubt you would see a substantial improvement in performance you just wouldnt have to change them as often.Kind of like extended service synthetic oil,though you might see some increases due to the decrease in frictional losses.The MSD 6AL I feel would help the ignition system burn every drop of fuel more completly if it can be used in the Ruby.I have done emission testing on non catted vehicels and they have always read less HC/CO/NOX with the MSD`s, More resistance = More amps or at least it should. I forget. Problem was no spark. Then you add plugs, wires, caps, and a lead to the coil from the distributor, all with resistance and wonder why you have poor ignition performance. Ok How about replacment plugs for the coil pack ignition systems that a lot of us have, for a hotter spark, better fuel burn, better MPG, more power, easyer start-up. Whether you do a complete tune-up or only change the spark plugs, spark plug wires (also known as ignition cables) should always be checked first. Further investigation showed that the front two front spark plugs (Cylinders 1 and 3) were completely fouled with thick black carbon, resulting in absolutely No Spark. 2022 DRiV Incorporated. Attach the test light to a good engine ground. The car ran for a season, but I ended up broken down while on a Sunday drive. Getting too low with resistance is a problem because the wires are then easily conductive of EMF/RFI through the insulation. Are we speaking about a different system to the usual Pertronix trigger? Privacy Policy | Terms & Conditions | Anti-Human Trafficking | Warranty With all PerTronix ignitions we recommend that a suppression style spark plug wire (also called carbon core) be used. The resistance should ALWAYS be measurable, so there is definitely a problem somewhere in the new wires, Champion ends, or the distributor-side wire ends. I understand Pertronix wants resistance in the wires.
