Am I missing something? Just received brand new B&S #590454 from Amazon seller. When the electronic ignition module was included in the circuit, the spark was very much weaker. I bought a upgraded cdi and upgrade coil and plug, everything had spark and buggy ran until I put new cdi and coil. Mercedes-Benz We have replaced the cdi, stator, pick up, coil, I threw out the packaging after a couple times and just use the markings as generic reference points now. No erosion should be on the surface and the firing points, should be free of rust or corrosion. This isnt exactly definitive, as we have seen working coils with 0.0ohms resistance. The ignition system should all plug in for your scooter without having to modify anything. With that done, I reinstalled the magneto, paying attention to the cylinder side / this side out lettering on it, and used a piece of thick-ish card as a gauge to set a gap between the flywheel and magneto (as seen on another video online), as I tightened up the bolts. It sounds like you have a DC fired CDI. Then, those components may not function properly and problems may arise. Never bother with points or condenser again! One quick prime push and a pull and the engine spluttered and almost started, so I was pretty sure Id sorted it. 3DEL6U13DEL6U1 but yet i dont have any spark? Do you know which Hammerhead 150cc model do you have? Also, what if any reading would you expect on the kill wire that comes out of the coil? I checked my wires from the stator I have 69 volts ac. In reality the ignition coil is held in 2 places: 1) by the rubber boot that slips over the ceramic part of the spark plug, and 2) by the sealing lips at the upper end of the coil. Unwanted trigger impulses in early attempts at using SCRs for CD ignitions were caused by electrical interference, but the main culprit proved to be 'points bounce'. We do not know the Ohm requirements for the newer Briggs and Stratton engines, Although from your analysis of the components 4kOhms seems to be an awful lot of resistance for the plug cap, It could indicate damage to the lead & cap connection and may be what is causing your issue. The main part of the insulator is typically made from sintered alumina (Al2O3),[10][11] a very hard ceramic material with high dielectric strength, printed with the manufacturer's name and identifying marks, then glazed to improve resistance to surface spark tracking. Hi, just posting to say thanks for the comments here as they helped fix my Briggs and Stratton 35 Classic problems. If you order the wrong electronic ignition conversion kit for your distributor Thank You ! Lucas-Compatible Electronic Distributor. Any output from cdi, and no spark. These ignition systems also tend to offer better fuel economy and less exhaust. CDI Connection Kit (Pigtail) This reduces the heat transfer from the ceramic, making it run hotter and thus burn away more deposits. Spark plug readings are only valid for the most recent engine operating conditions and running the engine under different conditions may erase or obscure characteristic marks previously left on the spark plugs. When Im In NEUTRAL And Press The Brake Tail light Doesnt Light Up . It continues to evolve as automakers manage to squeeze out a little more efficiency, or a little less pollution, with each passing year. For example, a sandblasted look to the tip of the spark plug means persistent, light detonation is occurring, often unheard. Kinroad XT150GK-2 buggy 6 pole a/c stator/cdi. Hammerhead twister 150. I have a hammerhead gt 150 with new coil, cdi,and when it cranks the coil fires briefly then quits sparking unless i wiggle key back and forth and starts sparking a little again. I have just replaced my stator due to the black/red coming up ofl and once I put it in it fired up and drove for about 6 hours of run time and it is back to ofl and not running. distributor) Ignition coils would fail due to age, overuse or simply manufacture defects. 3DEL4U13DEL4U1 The plug is very rarely the cause of no spark on the GY6. Most passenger car spark plug wires snap onto the terminal of the plug, but some wires have eyelet connectors which are fastened onto the plug under a nut. Distributors with 2-Piece Points, For Various 6-Cylinder Bosch Distributors, Hot Spark Types I When cdi out and ground are connected to coil, output from cdi drops to 1.5v and stays there until output wire is grounded which discharges the capacitor then output is back to 35v until hooked to coil. The ground side of the coil is connected to the breaker points. I do not understand why this is happening. The spark plug fires before the piston reaches top dead center. There was no bad connection between the lead and the cap because I had those separated and checked the connection which was good. The ignition coil acts as an electrical power transformer. With the spark plug attached to the high voltage lead, and the base of the spark plug electrically connected to the ground wire end of the high voltage coil, I then momentarily connected the primary coil leads to a 12 volt supply. I have a Briggs & Stratton Wheelhouse 5500 generator. Before the scoot ran so good I put my scoot in the shop and thats when my trouble started. Spark I ran grounds from the battery to the frame and motor using nice heavy wire. Ive stripped most of the harness already and have found nothing out of the norm. Set it and forget it - Never adjust points and timing again! Delco Distributors (4-cyl, 6-cyl): 4-cylinder Delco, GM If your distributor part number, normally found on the side of the distributor Followed the steps above (including bypassing switches) and got these results: Stator to CDI input: 68v to 71v Spark By lengthening the surface between the high voltage terminal and the grounded metal case of the spark plug, the physical shape of the ribs functions to improve the electrical insulation and prevent electrical energy from leaking along the insulator surface from the terminal to the metal case. Cold plugs are designed with more contact area, so they run cooler. The reading was the same as the old one, so either Im not reading it correctly, or the new one is bad as well. 3HIT4U1 2 4.6 volts I am working on a SunL 150 Purchased a new ignition coil. Some spark plugs have a tapered seat that uses no washer. non-vacuum-advance marine distributors, 8-cylinder Prestolite marine Ceramic is a fairly poor heat conductor, so the material gets quite hot during operation. If the kill wire connector coming off the coil going to the primary coil is suppose to kill the engine only when the kill wire is grounded to the engine how can it have continuity at all times??? Briggs & Stratton Classic 35. Im concerned Ive missed something. In essence, these two coils constitute a transformer, in which a small voltage applied to the primary coil can produce a very high voltage in the secondary coil, which can cause an electric spark to jump across the air gap in a spark plug. or faulty relay. Of course, after a few minutes when I then released the safety bar to stop the mower, although the engine slowed due to the braking effect on the flywheel, the engine didnt stop because id not reconnected the kill-switch wire Doh! 12.5v is the absolute minimum. In the standard system with points, distributor, ignition coil, ignition (Kettering system) points bounce prevents the coil from saturating fully as RPM increases resulting in a weak spark, thus limiting high speed potential. I have changed CDI stator and coil any ideas would be extremely helpful. Buggy starts and idles fine. Can the stator be installed 180 deg out (upside down) cause this? -Pulled up and locked the safety bar in place with velcro, and tried again, just in case no improvement 1. Oil has never been changed, but topped up once (I think). sell only what we have in stock. Like some of the other commenters in this website, I have a problem with no spark. The electrodes thus sit just beyond the reach of the passing apex seal, while the spark is accessible to the fuel/air mixture. Normally, when you put the key in the ignition switch and turn it, you will have three positions: One major sign of a bad ignition switch is the instrument panel, not lighting up in position two. accept it as a retuned item, within 30 days of purchase, and provide a refund to Ive tried the bypass switches and I ordered a new ignition switch. If it does not start compression may be low. I have the ground from the battery going to the frame and the engine with new wire and connectors and cleaned contact locations. The internal and external surface of the cap should be clean. Also the coil has been replaced as well as the spark plug. Found the problem. [citation needed], Since the CDI system provides only a reduced duration spark, it's also possible to combine this ignition system with ionization measurement. that reading is okay you should get 0 Ohms from the body of the coil to the stop switch connection. They do make harness kits. In my case, I performed this test with the electronic ignition module disconnected from the magneto coils, and had a strong spark at the spark plug. Instead, they use a sensor that tells the engine control unit (ECU) the exact position of the pistons. New coil reads 6.0 ohms right out of the box. But why it would matter is you are correct it generates voltage either way but if you could put it 180 degrees off the piston and valves would not be TDC when it should be and the exhaust intake valves would be out of time as well with the firing. Although your 300cc engine isnt the same as the engine that this guide is intended for, the steps should generally be the same (but not the pinouts). Spark plug lifespan was increased to at least 50,000 miles and points lifespan was greatly extended from 8,000 miles to at least 60,000 miles. The first would be to develop another means of triggering the discharge of the capacitor to one discharge per power stroke by replacing the points with something else. The old stator was pretty beat up, turns out there was a loose nut magnetized in the flywheel and tore up the old stator. The tested range applies to this lawn mower engine or engines with the same coil It may not apply to your generator. This can result in a less efficient burn and increased fuel consumption. Ford (US, with Bosch Note the wrapped ignition winding, and trigger module. No matter how They were unsuccessful, but did provide much data on the advantages of such a system, should one be built. This was thanks to Bill Gutzwiller and his team at General Electric. I PUT A NEW SPARK AND NOTHING. -get wife to try and check for spark by removing plug, but keeping connected to magneto and wife holding bottom of plug to mower body (with insulated pliers) whilst I pulled cord to turn over engine; results inconclusive, but after argument and scuffle subsides (following Police intervention), 99.9% sure no spark is present. Leave the #4 wire in the connector. UF262 D585 Round Ignition Coil . fees, etc., but only if the ignition kit is in pristine, like-new condition. Typically a weak spark can cause a mower to shut off when it gets hot and the resistance of the ignition module increases. stator :blk/red=53.4 vac. The reason why I am giving these details is to provide a simple and certain way of determining whether the coils are working. Is this an issue? I removed pin 5 (kill switch wire) from the CDI box connector. CHECK WIRES ON THE COIL AND MAKE SURE THERE NOT LOOSE AT ALL. I checked the magnets on the flywheel and they were still strong enough to hold a screwdriver, but I noticed a smaller amount of black crud on the flywheel along this edge where the flywheel would pass the magneto, so I cleaned that off too with the same emery paper. I am getting no power from either. again on behalf of us garage mechanics thank you sir. I then added a additional ground wire from the frame to pin 3 still no voltage to the coil. Open/nothing Because the spark plug also seals the combustion chamber of the engine when installed, seals are required to ensure there is no leakage from the combustion chamber. the side of the distributor body. Forget the kill switch, just cut power to the CDI. If you do not have battery voltage there, set your DMM to AC and test it again while cranking the motor, if you have A/C voltage then you have an A/C fired CDI. (6-cylinder) Then, it is likely, because of loose or corroded electrical connections, in the ignition module. 3AUT6U13AUT6U23HIT6U1. Harris, undergraduate of the City University London made a detailed electrical engineering analysis of the Marston design as well as automotive engine measurement trials to verify fuel economy. I ordered a new coil from amazon for my 6 hp Briggs, the ohm reading is 16 k is the new coil bad ? Xing110 By examining "hotter" and "cooler" spark plugs of the same manufacturer side by side, the principle involved can be very clearly seen; the cooler plugs have a more substantial ceramic insulator filling the gap between the center electrode and the shell, effectively allowing more heat to be carried off by the shell, while the hotter plugs have less ceramic material, so that the tip is more isolated from the body of the plug and retains heat better. [citation needed], Device that generates sparks in internal combustion engines. Afterward, numerous companies started building their own throughout the 1960s and 1970s without licence. It starts and runs fine until your throttle up past about 35, then it starts bucking and sputtering like ya out of gas or something, then when ya back of the throttle it runs ok again. When bypassing your switches, were you sure to remove pin #5 from the CDI connector? So, maybe its in the plug?? The magnet on the flywheel seems strong, but is it possible the magnet has weakened to the point it no longer creates an electrical current? cap, Stealth modification - maintains stock I do not know what voltage is induced in the primary coil when the magneto is functioning normally, and I do not know whether using a 12 volt supply is the most appropriate for a test such as this. It will not start. turns over easily Anyway No Spark. Im not sure if this is the problem or just the source of the buzzing. The resistor would change the reading, However if you get no reading after the resistor it would suggest the resistor is damaged. etc. Is this style unusual or discontinued. Please reply and well go from there. Is this too high? The coil readings in the video are suitable only for that coil type, Although if you coil is producing a spark it is a sign that it is working. The problem is most likely related to incorrect wiring or a problem specific to the circuitry of the generator. Any ideas??? Im guessing CDI unit, but why would it not work above idle, but be OK at low RPM? electronic ignition conversion kit: Replaces points and May need to be in a relatively dark place to see spark. The stator ignition coil puts out about 70 VAC. The starter clutch and flywheel do though. Id say thats nothing to worry about unless you have two key ways 180 degrees apart on the crankshaft and stator but Ive never seen such. Im another one with no spark. any help would be wonderful. Copper was the material chosen for the task and a method for manufacturing the copper-cored centre electrode was created by Floform. Starter is New. Ive replaced the stator, coil, starter, starter solenoid , and CDi box, all I get is a buzzing sound when I try to start. Any help??? 3. -Not fuel locked; removed plug and checked for excess fuel The voltage regulator is not connected DISCONNECTED, Voltage at the red/black stator wire not connected to CDI is 110 v AC In this case, plugs with the same heat range numbers can't be interchanged casually as being equal. Some cars require a hot plug. Thanks a bunch for your help and comments. The crankshaft position (CKP) sensor, monitors the position or rotational speed of the crankshaft. I do not see any spark in checker and at plug , no pop when lighter fluid is put into spark plug , 4.85 k ohms reading on coil. Marston. Distributors, 1957-74 8-Cylinder Ford Vacuum-advance i had it running for 1 day and me being stupid i took it mudding it ran for about 2-3 hours. 3BOS6U1 pin 1. input from trigger .01 With your experience, would you say that the cap alone should have almost no resistance? Checked another identical new coil at dealerreads 6000 ohms. So, does that mean the pickup module is bad and do I have to replace the whole stator assy.? Distributors with 2-Piece Points But, I get 0 ohms between the stop-switch connection and the coil body which surprised me as I thought that that was the connection made by the stop-switch (ie it grounded the coil to stop the engine) can you clarify that one again? Changed fuel lines and back lines with new gas. My Electric Start Button DO NOT WORK Microsofts Activision Blizzard deal is key to the companys mobile gaming efforts. new reads 6200 ohms..old reads 4800 ohms. I have strange problem, just like few other people aboveit is 1998 engine, model 10c902, type 20138 E1. Just like before: while cranking the engine, use a multimeter to check for voltage at the two primary wires of the ignition coil. Additionally the total resistance (11kOhm) is basically the sum of the partial resistances of the coil and the cap (7 4). Or just the source of the coil to the stop switch connection,.
