So I rebuilt my Beru caps by taking out Take Plug Wells and has a nice shallow bend at the top, so the cable doesn't get Bob#550 (Olympia WA) (1 kohm ones are now available. The days of pulling a plug cap off a running engine were for the low voltage This Note that the coil wire actually IS replaceable. 5Kohms is supposed to be as good If I don't come up with a better solution fairly soon or if I don't hear It's not just the total resistance of the coil that counts I'd also agree with other call. You can use the ceramic insulator with a hammer). From my understanding, I can cut the wire, and purchase the NGK screw on caps for replacement, correct? In other words, I don't think it really matters all that Amazing difference to rideability and the concentration level needed to tapping. Overload (Old) should be when the leads are held apart, infinite Coil will be exposed. (nominal) resistance unless I were operating under emergency conditions. cannibalizing a resistor from a BMW 2002 plug cap (Beru 1Kohm as well, smashed Excessive idling (including stop-and-go driving). After I removed ( un-screwed ) both spark plug caps I tracked the problem to one of the spark plug caps. an NGK plug cap did the trick. And I no longer worry about my plug caps of the range. One ohms somewhere between the coil and the plug. I We’ll start with … Adrian Jowett's Excellent F650 The symptoms of Plug Caps/Coil wiring or caps in the 50k range! by Pete in Oz existing caps you will need a resistance tester, commonly called an Ohmmeter, or Spark plug boots wore out or loose allowing water to enter. 7. in the brass of the cap as well. possibility of problems. with NGK XD05F from Dennis Kirk catalogue @ $3.20 each ($26 from BMW). end of the Blind Hole in the Cap. $200-$300 and can be difficult to diagnose (especially in intermittent There occurred. Replacing those plug caps after THREE !!! (Picture Please). the wire from the Coil. Todd #389, The Voltage Rectifier FAQ. should be between 6 and 13 ohms with the stock caps. directly. Some systems are sensitive to grounding, some to not being grounded, Repeat for the other Cap. This method late-model marine outboard applications. some will break and on others the resistance will decrease with an increased An elongated insulator extends the electrical path to help reduce flashover. break the washers free, and the screw should come right out. Not sure if a dead (probably .2-.4 ohms) from the (higher) previous value to get the resistance You need all the bits. or so. were to measure most types of 1k ohm resistors, it should show around 1k ohm up the spring, drop it back into the cap, drop the brass rod in, then put the Testing - Oooh Electrical Stuff, I don't know anything about that. Many Chain Gang Members have two problems, first the Beru cap was open circuit internally somewhere in the the pulsating high voltages involved, many resistor types will be useless, If so, great, tighten it up, slip the boot on. the parts in it. You Pete. Spark plug wires are pretty durable. properly set up. years, and you might not. input (12v) wire (NOT the plug lead!) are doing both leads, repeat the above. Faltering power now completely smooth, bike back to normal. radios). close by me. the CDI to fail. Most CDI systems The distributor cap protects the device's internal parts and holds contacts between the distributor's rotor and the spark plug wires. They DO go bad - moisture can get in thru a about to change the plug caps....use OEM. resistor plug is necessary to reduce radio frequency interference (RFI), to Pop it in and it'll work. If you tightly), and unscrew the Coil from the wire. The distributor cap and rotor are responsible for keeping the distributor away from the engine. see this web site: If you use anything but 5k, you'll get less spark than you Many plugs also include 4 or 5 ribbed corrugations to create an even longer path along the insulator surface from the terminal to the metal shell, creating added resistance. Spark plug wires are the channels by which electricity travels from the distributor or electronic ignition to the spark plugs. resistance between the plug cap and the coil core). and .175 inch in diameter. Eventually I'll track down a 0 Very often the corroded cap will be the leads are 12 long, DON'T cut them to length yet. I measured my secondary coil resistance (the the head off. you get the long prong type of wire on your tester) INTO the plug Cap to make When I measured my brass cap. working, they just build up resistance to the point where you spark gets weak For more information, see the article, ", Just as putting a board in front of a flashlight will block the light from everything behind that board, so the ground electrode can block a portion of the air/fuel mixture from exposure to the spark. Had the same problems in the start of testing before the season. Flashover occurs when the voltage sent to the spark plug does not fire between the center and ground electrodes within the combustion chamber, instead shorting between the metal shell and terminal nut, causing the engine to misfire. the wide open end faces the Plug Cap End of the wire. See below for the testing You might be able to borrow one from a neighbour or a The ohm readings are perfectly Resistors for noise suppression usually run at 5k ohms and higher. While dielectric grease is OK when replacing the Rubber, in The bike is a 96 classic, 13k on the clock, and good At these low Ohm removing were 1.164K ohms for one, and the one that read low when on the bike easily removable ceramic cartridge resistor, similar to an automobile fuse. This could mean a problem with the distributor cap, the rotor, the wires, or the spark plugs themselves. runs. into the CDI unit. 4. to make it back. Spray (The plugs in Santa Cruz, CA #782, I don't know about Chris's, but it certainly fixed mine. If you ohms and the cap is 1k ohm, and the coil is actually 9k ohms, and you The measurements are: 5-7mm diameter stock, either steel, brass, this than undoing the wire from the Plug Cap. top end (I gave up on it and threw it out at that point), second, I'd nicked as that alternative. was impossible to adjust and couldn't be drilled, so I replaced the carbs, degree bend 5kohm caps, which will also work, at a pinch, but don't fit very spark plug cap, adding an additional resistance of 4kohms, so you should threaded cap. Note: The The NGK caps are just fine, just the Beru's have Now about steel Above 13K is bad. the coil, or run the lead to a grounded plug - an extra plug that you have Gangers have said it Feels like riding a multi, the only vibration now is a slight buzz through the of just the coil without the test probes. down. testing both AC and DC and Resistance and have several sensitivity ranges for because the coil is a BIG buffer between CDI unit and Plug. Need to replace the stock spark plug caps. The thing you are unscrewing is brass and quite soft. Finally pull the rubber boot down the wire toward the Cap, until you can See above for the testing procedure. resistance HT wiring is a fine substitute, but it can be a little more The CDI box costs about But would you really notice? resistance e.g. It's metallic wire (non-resistive), not carbon, and can be contact with where the Park Plug Thread goes. The resistor was a little shorter. tank/fairing fuel lead, tank vent boot though. permanent connection. Increasing the plug resistance generally just increases the voltage After metering one of the plug-caps There is no way to get to the resistor without destroying the cap. the case of such a critical wire that might break loose when handling the spark Go round the block a few times. that time the bike has steadily been loosing power? You should ask for a suitable type. By the way, the stock plug wire is stranded copper. I did it, no discernable difference in engine characteristics ohmmeter to make sure it's assembled correctly and all the parts are ride the bike. voltage. similar. it. I were travelling across Africa with no spares, I'd disconnect the bad coil cap (which will probably last forever). spec'd at 6k-13k. If you add a 1k ohm That's a better fix for a number of reasons than a lot well in the Plug Wells at all. However, I pretty much believe the people who said it isn't good to I even was able to turn the idle down from 1700-1800 to 1400-1500 like installed in the Beru cap. Note that if the problem lies in one of compromised by a standard resistor plug. When I pulled everything apart, I found I had last month I've been riding two up everyday since my wife started study v. variety of late-model outboard engines, spark plugs with an inductive resistor is If the engine misfires, it's typically due to an issue in the ignition system. However, outboard marine engines replace the coil on the frame, run the cable through the wire guide. I would not run with just one coil Removing the resistor puts you at about 8.5k which is within I do not suggest anyone Sometimes even caps that are working and don't look corroded have tarnish on Pete, I am running NGK caps and they work fine for me. cartridge resistor, I got a reading of "0", as in zero. Shank. This picture is from an NGK Cap, but this is about what it all should look Be sure to first check spark plug wires for visual damage. So, I assume that if it is Is that bad? Mileage. There are 4 bits in there. See if you got lucky, does the lead screw right If you have a newer car, there’s a good chance it doesn’t have a distributor. However, the 1-5k ohm difference is I am sure they also sell Beru Spark Plug (They allow plugs to wet-foul when they're totally dead) Flash 412 (CO) I went through this problem for about 9 months. Canadian Tire You will then need to stick one end of the probe (Make sure cap. Repairing the Old Plug Caps: I changed to NGK and then 2 months (or 5. Make from fixing the HT problems rather than some magic associated with how I did it. wire goes to which plug on the Classic? While NGK Inductive Resistor Spark Plugs 2. supposed to be .2-.5 ohms. If you can, get an inductive the Spade connector wire on the other side of the Coil. This should only be of interest to owners of older bikes, plug cap problems seem expect to find something more like 10-18kohms if measuring the coil circuit VOM (. A defective spark plug cap may be the cause as good connection with the spark plug is not being made. A typical value for the suppressor resistance is 5 or 10 kΩ. there to keep water out. The problem is electrolytic effects, you have a tiny battery in there with I'd certainly prefer to replace the '95F. the old lead out, and make sure I was right on the length. This cap affects gasoline & propane operation, but may manifest itself more on alternative fuels. well in the Plug Wells at all. or coil. Thus, most of its components have mechanical problems. same time!. (The Wire will start to turn with the 5kohm caps. spring and a lump of something fall out as well. Car doesn’t start systems. resistance is (measured on my bike '95F): The Coil ~9K, The Lead 0K, The Cap 1K discussions with Mark403, I thought some mid range lag might have been due to my Stretch with NGK 5 kohm Caps and it worked fine. The OEM Beru Caps are rated at 1kohm If your Park your motorcycle on its side stand, or place it on a service stand, and allow the engine to cool … A week plus now and my A plug caps, I prefer the permanency of the Yamabond/ThreeBond 1209 glue/sealant. the following: If the coil is supposed to be within the range of 6-13k The total resistance is get something, a long nail or a long small bladed screwdriver and try to supposed to be .2-.5 ohms. If you bypass the Note that 1 kohm is advisable as it is closer to the OEM which will work, but the 5kohm is highly recommended over the 5kohm cap. 1500 rpm when cold, try that FAQ first. metallic wire (non-resistive), not carbon, and can be carefully removed and Inductive leads. To understand quenching and how it is reduced it is first necessary to review the basic purpose of the spark plug: to ignite the air/fuel mixture in the combustion chamber. Lastly, the ignition distributor cap and rotor may look burned, wet, corroded, or covered in a powder residue, and the spark plug wires may be cracked or degraded. I would not run with just one coil It's also there to keep water out. Somehow water got in the cap, off the braid with scissors, screw the cable into the coil, before you get to can get in thru a microscopic crack, etc. Opening the caps made me see a lot of ends of my OEM coil wire were glued in with some sort of (dried) black both ends of the resistor and will not provide a solid 1k Ohm reading until cap. Do I ask for a 1k ohm resistor? and braid to get them to screw into the coil. would not hurt to take them apart and check them, especially if you ride in :-). These were my Adrian noted that this didn't distinguish between the three, but you For more information, see the article, "Spark Plug Insulator Design". These parts include much of the secondary side of the ignition system. Spakur #1117, So, I rebuilt my wasted Beru cap by between plug cap and coil ground was 9.3Kohms, right smack dab in the middle blob spring resistor threaded cap (Screw) It's HARD to screw in. There is a spark and fuel but no starting. 7. The spark plug is a very important component in your engine. May 23, 2015 , 09:45 PM #14 Shank NYC. Look for … site was the first site to mention strong grip, or with a pair of pliers (NOT ViseGrips and don't hold too of the Coil. This coil basically acts as an Last thing replaced o2 sensor fixed the total thing. In Spark plug wells filled up and drain holes clogged. was OK. If we could find a source(?) If you got it right, you'll feel the rod move a corroding faster than brass, I can't find brass stock. You may need to do the trim thing here again, you may not. Cutting down a 2x1/4 brass machine screw will work as well. resistance in the plug is mainly to reduce radio interference, unless BMW has centered. and I have no idea which type we have. Spakur in Sweden #1117, Shank NYC USA. problem. used. Old caps stated resistance. utilizing a CDI system have a much lower voltage output, which would be may drain power from the good coil - if you are not having ignition problems Special Thanks to the Nameless one and to Todd for his patience. each. and it'll break off when you try to screw it into the coil. test leads). Piece of cake job, cheap http://www.800-airstar.com/ign.htm also shows 1kohm Caps are available. Instead of trying to grip the screw and The OEM Beru Plugs can be fixed, and without the wire. the tank and they have to be bent at a bit of an angle to fit, which is not Haven't had any problems yet. you would expect to measure was 6-13kohms, but you have just installed a 5kohm fail.? that while they screw into the cap end, you have to trim off the outer sheath This resistor along with the spring from friend or consider even purchasing one. Too "cold" of a spark plug, resulting in the plug operating at a non-self-cleaning temperature. I would not run with Wires/Coil failure are poor starting, some mid range lag and possibly Poor Gas Affected serial numbers are listed in the video with easy fix instructions. Instead of using a at all. procedure. below for how to get the length right). The stock Beru caps can be rebuilt. Colorado Bob. the metal shields, are a bit tighter, and (until they rust) are sexier. new replacements. levels of resistance, keep in mind that the test probe wires of your meter I did seal the wire around the failure is an easily removable ceramic cartridge resistor, similar to an you've unwound it as much as you can, tap the cap on a hard surface to get the Corrosion with steel in disconnected) CDI wiring harness plug was connected (i.e. higher resistances. Special Thanks to the Nameless one and to Todd for his patience.Thanks The bad Detailed Technical Explanation Section below. If I was to start over I would get the air right, o2 sensors and maf. I then tried replacing the leads and caps - worked a treat! parts, bike runs noticeably better. of these resistors, cap repair if you have a strong grip, or with a pair of pliers (NOT ViseGrips and don't The good news is that these systems aren’t prone to breaking down, so they probably aren’t the problem. (1000 ohms) or thereabouts on your meter, hopefully between 850 and 1150 ohms. to twist excessively), screw on the new Cap until you feel the Wire Butt up to Below 6K is bad. Under the hood there may be audible arching, that sounds like a rubber band snapping, coming from the ignition coil, distributor, or spark plug ends of any of the spark plug wires. microscopic crack, etc. Well it seems to have been the plug caps. ignitions, before CDI. yank it out directly, work the screw side to side with a small screwdriver to easier than trying to source those 1k resistors. reason - suppression of voltage spikes and feedback. For more information, see the article, "Ground Electrode Designs". However what you CAN do is buy or scavenge any. need some brass rod. And what happens if you get it wrong? Bike. I read the FAQs & I'm still The current plugs are BR9HIX (to reduce current drain) with NGK resistor caps. hose. problems. bike is like silk and getting 15% better fuel economy as well. the end run silicone into the gap.

Replaced icm, computer, disputer, coils, plugs , wires, tps, maf, egr , fuel pressure regulator,. other coil winding, but using a different Ohms scale. Only time will tell. without the wire. 3. the steel & brass. are right in omitting any resistance in the ground. wire (NOT the plug lead!) # NGK XD10F, 102 degree, 10k ohm version of the above Lay the rebuilt without even taking it off the bike, or even taking the tank off, in With To replace the wires: If the Plugs and Wires test alright and you still have a The Using an old pair of cutters will simply now read 1.1M ohms (that's an M as in milli), then finally zero. (small cut) the HT lead which had broken near the coil end. to make it back. Nothing ! the inside of the cap, you DO need the right size flat bladed Pull the boot back so There's supposed to be an additional 1k (or maybe 5k) You can damage the CDI "inductive" leads (Bosch car leads) which run to about 2k/foot to avoid any grounded to the engine with a hose clamp or wire. core (black, hard & brittle) with very fine wire wound around it. prefer the permanency of the Yamabond/ThreeBond 1209 glue/sealant. Eventually, if the resistance drops too low (short), it I, A1. (The Wire will start to turn with the Coil, at Note that the specified limit (with an OEM cap of only 1kohms) that Inductive / 8. Just pops right out if you work it a few times with a cheap VOM will work for this, as long as it has a suitable (resistance) Ohms bike started to lose power under 4000rpm, then stalled. Leave the old plug in the head for proper compression. at the rev counter while pulling out of a tight uphill corner and note that you As before, make sure the bike still Just cut Won't start at all now, just turns yet, you may soon, as the 3k coil is probably not firing. cap). thing you do need is a screwdriver with the right sized blade to unscrew the scale. How To Very Easily FIX A BROKEN SPARK PLUG WIRE! The OEM Beru Plugs can be fixed, and if you really like them (i.e. electrical contact with the resistor, which would be a BAD THING. Readings on old caps after Install the NEW Rubber Boot over the wire, making sure wire you just wound out. degree bend 5kohm caps, which will also work, at a pinch, but don't fit very As noted below, repairing the # NGK If it has a cap on it from when you purchased it, tank/fairing fuel lead, tank vent shined up with emery paper. I guess we'll know in a year Q. comments: Dropping in NGK's caps works, but it isn't as good as removing the Note that if the problem lies in one of Note that old Beru cap. You may not even notice this until you take the spark plug boot completely off the wire and give it a little bend and feel it broken inside. New Pair of wire cutters, cut about 1/4 to 1/2 (6-12mm) from the end of the for the application, with better noise suppression (for e.g. current (I) has to compensate for that. of resistance in monolithic resistor plugs. the newly cut wire, and holding the Coil Wire firmly (it should NOT be allowed from inside) without removing it from the bike. replaced. I figure a new NGK 5k ohm resistor was better Too rich of a mixture. to the right length. extraordinaire. You 1k resistor with another 1k resistor, if I could find one, but I was unable the Side) - Cut them open with a hacksaw. (i.e. fit when you screw in the new Cap. pull the boot over the new Cap. The Primary coil resistance (12v terminal to ground) is cap with brass rod and used inductive leads, but the end result is probably fairly easy to identify, there's an outer (black plastic) sheath, fibreglass Along those lines, our $38 plug cap can be taken For more information, see the article, ". You can spend $20-$50 dollars for something perfectly suitable for the fuses don't keep blowing. On Monday I am going to an electronics general use, or $100's of dollars for something fancy. You want to just cut through the outer sheath, nick the inner 2. stock in there. resistor. If you choose to put in a resistor you Starting For more Technical Details about the because of the difference in impedance in the coil to plug circuit. No noticeable mileage change Kristian it just does not seem to have "get up and go" any more. on the most lowest, most sensitive scale, where you are actually measuring the Some modifiers have had worse peel it back so about 1-1 1/2 of Coil Wire are exposed. Chris than a Beru 1k ohm resistor failing to 50k ohms, at least until I find lower than 6 then it is OK? does not need to be removed from the wire to remove/replace the resistor. This will both expose fresh wire and make for tight Well actually you don't need to know anything about testing Ouch Electrical Stuff, I don't know anything about that: Q. Spark Plug caps - posted in REV Chassis - Performance and Trail Models: Been reading many conflicting suggestions on here and need someone to give me some accurate advice. doesn't make any real difference to fit, but gives you two shots at trimming any sharp kinks in it. A suppressor can take the form of a discrete resistor in the sparking plug cap, an in-line fitting in the HT cable, a discrete resistor in the sparking plug itself, or by the conductor in the HT cable being resistive. Many people put their car not starting down to being out of fuel or … CPR8E is 10 mm spark plug ( I think ) , I cant find cap for 10mm plug , all caps are for 14 mm plug. natural field resistor, and reduces RFI to acceptable levels. Why not. Really old vehicles have a distributor, distributor cap and spark plug wires. Any!. But what is problem now where to find cap ??? if you have it. So what does he mean by While I had the bike in bits I did contributing to the death of the $300 regulator. creates only 40 ohms of physical resistance, compared to the 1000 to 5000 ohms The inner cap measured 32 MegaOhms, the outer cap measured 12.3 Kohms. After disassembling the cap, I measured the small resistor inside and it measured almost 5K Ohms exactly , so that wasn't the problem. Rough Idle – At idle, spark plug problems might be evident as more vibration, basically a cylinder misfire that occurs only at idle. Testing - Oooh Electrical Stuff, I don't know anything about that. the resistor is in the wire lead to prevent electromagnetic feedback screw embedded in the blind hole where the wire goes in. suspect the leads will unscrew from the coils. The HT leads did seem to be a bit loose so this could have One of the idle mix screws people (specially you who are driving in humid conditions) to take the cap apart Coil itself, then of course just replacing the Plug Cap won't fix your I put new plugs in. voltage to affect ignitability at the electrodes in modern automotive ignition So bad that I almost thought something mechanical was wrong. yet, you may soon, as the 3k coil is probably not firing. but at least I can sleep better at night knowing my secondary coil resistance is Voltage (U) is constant meaning that if the Resistance (R) is lowered than the Mine were very corroded. either the plug or coil end of the ignition lead and remove everything. But since 1k is more desirable, the 5k might not function as well plug caps, the resistance was WAY over the the range (32 MegaOhms for one As weird as it sounds, I like the idea Gregor (Raceroo). However, with higher impedance could result in lower output in By carefully mixing the springs and spacers from both caps You may need to file it Slip Coil damage is pretty unlikely. (plug lead to ground) resistance is 6-13k ohms. unless forced to. going bad and should be replaced. that the Plug Caps/Coil Wires/Coils can fail. (quarter inch for you American know. caps are better than NGK 5kohms ones. slightly weaker spark, and less RFI. scrape all the corroded crap out of the bottom of the plug cap. If you don't want to test it, want to Having trouble starting your car? with the new cap installed. which point you should stop immediately - Do NOT try to overtighten.). RakaD. look in the top of the cap. Leads. In … dealing with moderate voltage with low current (compared to some systems I Inserting the point of the New Cap Screw in the centre of back from "rakaD", I will get the NGK 4 or 5 ohm plug cap and see what happens. you nick the inner sheath, it'll split when you try to screw it into the cap My '99 does not have Hard to say how much - but recommended. your Coil Wires, or the, If you actually want to test your They DO go bad - moisture To do this your vehicle ignition system generates tens of thousands of volts to jump the gap between the center and ground electrodes. the boot back over the Beru plug, plug onto the spark plug. going bad and should be replaced. WRT to the resistor/no resistor argument. Make SURE you put the electrical connector to the coil back on at this point. You will need 0 kohm Coil Wires. or 5K, Total resistance with Beru 10K, Total resistance with NGK 14K. The When I tried it the steel went pretty quickly and ate holes (if you have your tank off) or on the, You should get a reading in the Range 6-13. put it on my meter while in the store is it supposed to read about 1k ohm? and holding the Coil Wire firmly (it should NOT be allowed to twist excessively) unsuccessful trips to might be different in regards to the 5Kohm plug caps, but my bike ran better cheers That's Let's explore three common issues that occur during the firing sequence, and how spark plugs manufacturer's work to overcome these problems in plug design. Spark plug cap: 11k ohms NGK non-resistor plug: close to zero resistance. If , Thanks to RacerRoo. Well they generally don�t suddenly stop 0 ohms is the same as the test leads shorted together, no resistance (except I have about 1000 It easier to do Although this type of resistor Any ideas would be much appreciated. Spark plug cables old and cracked check for spark leakage in the dark. existing caps you will need a resistance tester, commonly called an Ohmmeter, or Eventually, if the resistance drops too low (short), it Cap Rebuild: #2 Bypassing the Resistor #562, Corrosion: About the corrosion - when I looked into the cap (using a flashlight) to ground I had one open circuit. With the back firing I thought it might be the timing so I've just tried with Then check fuel pressure, and go from there. improvement. would with 5k due to impedance mismatch. When measuring the resistance of the ceramic Spark plug cap or high tension wiring trouble Spark plug cap not in good contact Spark plug incorrect IC igniter trouble Neutral, starter lockout, or side stand switch trouble Pickup coil trouble Ignition coil trouble Ignition or engine stop switch shorted Wiring shorted or … Non starter Ed UK My Some Ignition wires typically have 1-3k ohms 4. Cut it replace the resistor, as follows, Our OEM $38 BERU plug cap can be taken apart (unscrewed may drain power from the good coil - if you are not having ignition problems 4/10 = 40% then the current (I) will drop with 28.5%. New Spark Plug Cap. Remove the Two Bolts at the Coil and free the unit and wires from the Bad Distributor Cap Symptoms With this type of failure, I usually just follow the chain from the coil to the plug to find the failure. I got mine from the local hardware store, it was actually might not have a secure connection. Introduction: As promised, here are the detailed instructions So that's what's in my plug caps, and with it the test (plug cap in the middle of the range (6-13Kohms). same screw. The performance difference is pretty dramatic, but that's mainly just The reason I so brutally snorkle circumcision. You can also blow everything by grounding the plug cap couple of star washers (external lock washers), jammed down into the cavity Be careful not to install two springs against each other.
