Heres my pin out. Just dont have power at switch. Your email address will not be published. Your email address will not be published. Initially I thought that gasoline was contaminated, so I had the fuel tank removed and cleaned. Why is the voltage so low. Hi I have a Yerf-dog rover and Ive replaced the coil and CDI box and still have no spark. My name is Randy and I need help. Plug gap is .025 & condenser gap is .020 & condenser points have been cleaned. Sales@Hot-Spark.com . The same numbers have very different meanings between different manufacturers. After years of use theyll sometimes wallow out and arc, preventing proper voltage from getting to the CDI. The switch is fine. When it cranks for few sec,the kill switch will kill it. mgh housestaff manual 2022 pdf yummybazaar. Lift the hood and locate your car's ignition coil. Although there are many differences in wiring between models, most GY6 ignition systems work the same as shown in this illustration. Try checking the inlet boot for any cracks or dry rot. Current flows from the battery through the primary winding of the coil. Its the black boot that connects the carburetor to the engine. Is this also a problem? I have not used the generator in 3 years. Gap adjustment is not recommended for iridium and platinum spark plugs, because there is a risk of damaging a metal disk welded to the electrode.[24]. What is your voltage at the coil primary(the hookup leads on the coil) while cranking? Turn the motor over and see if you get any pulsing voltage around .5 to 1 volt. [17] Waste spark systems place a greater strain upon spark plugs since they alternately fire electrons in both directions (from the ground electrode to the central electrode, not just from the central electrode to the ground electrode). Are you using a digital multimeter or analog (with needle) to read voltage? Note the wrapped ignition winding, and trigger module. This procedure is assuming you have pulled break release / kill handle back to the run position. An ignition module, requires some type of external input, in order to activate. For example, a sandblasted look to the tip of the spark plug means persistent, light detonation is occurring, often unheard. Meggering out the individual wires say on 500v would have shown this and also a good way to check if your earth is good and not corroded, thats if you have access to a megger or electrician friend. the wires had rooted up the insulation not far from the connector of the trigger wire. (4-cylinder) I have replaced the spark plug. 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. if you have a question. but it is a brand new cdi. [citation needed]. After this repair the engine would start briefly but stall after a few minutes. Blue/Yellow to Pin #1 Once the voltage exceeds the dielectric strength of the gases, the gases become ionized. Voltage at COIL is 18v AC when measured across both ( Volte meter leads one to each connector at the same time) But what I want to know is, if its of.. Not running, the CDI box light stays on.. Wont that drain my battery? One company at least, Tung-Sol (a manufacturer of vacuum tubes) marketed a thyratron CD ignition, model Tung-Sol EI-4 in 1962, but it was expensive. Very good. If the crankshaft position sensor has failed completely, it will not send a signal to the (ECU) at all. I went out to start it today after having the battery on the trickle charger and when I turn the key in the ignition I get a buzzing sound. Basic GY6 Diagram. Everything is disconnected except for the ignition system wires. for your vehicle. The stator ignition coil puts out about 70 VAC. Ignition Winding: When the electronic ignition module was included in the circuit, the spark was very much weaker. Pluged the # 5 wire in for the CDI frist reading 1.050 unpluged 42.6. Conversely if the plug is too hot, the porcelain will be porous looking, almost like sugar. The need for advancing (or retarding) the timing of the spark is because fuel does not completely burn the instant the spark fires. If you do I would try a new CDI. New coil reads 6.0 ohms right out of the box. Except no spark. Hot Spark Types I However, vehicles that use DC-CDI systems have more precise ignition timing and the engine can be started more easily when cold. https://www.buggydepot.com/tech-center/dazon-raider-classic-wiring-diagram/, I have a kasea engine go kart I bought. NOTE: Suspect the (ECM) only as a last resort. (6-cylinder) 3BOS6U1 number and the number of cylinders of your engine. One of the most common symptoms of a faulty ignition coil. Cleaning the magneto surfaces and flywheel, and re-seating the magneto seems to have cured the issue at the moment. No matter how Read the article above or show it to someone who knows how to work on buggies. No spark, good magnets I believe, coil resistance readings are 2.63 K, brand new sparkground (stop) is not touching anything, separated the wire, tried 2-3 positions coil from wheel, cleaned the wheel. Ignition modules are solid state switching devices. When Im In NEUTRAL And Press The Brake Tail light Doesnt Light Up . I have a tumberlin crossfire 150. Chris-Craft, Forget the kill switch, just cut power to the CDI. : Bosch With points, the timing will drift; power and fuel economy will suffer. Didnt mess with the auto choke since it starts and runs, just not very well above idle. The central electrode, which may contain a resistor, is connected by a heavily insulated wire to the output terminal of an ignition coil or magneto. Plugs which are used for these applications often have the end of the terminal serve a double purpose as the nut on a thin threaded shaft so that they can be used for either type of connection. Obviously the 6 pole worked originally before I bought it but then was damaged before I got it. burn and wear within a few thousand miles, long before the recommended Distributors: Electronic By contrast, Champion, Bosch, BRISK, Beru, and ACDelco use a heat range system in which the numbers become bigger as the plugs get hotter. The electricity must be at a very high voltage in order to travel across the gap and create a good spark. Stator is putting out 17 VAC I did repeat this experiment with a 6 volt power-pack as the power source, and was able to produce a spark at the spark plug. I only get a reading when the engine makes the first turn or if I just bump the starter. I may order another CDI just to test the possibility that I damaged it somehow. These mechanisms advance the timing in proportion to engine load or engine speed. If the coil is different or newer it may have a different acceptable range. Replaced cdi with 2nd new one, still same Be sure to also connect your toggle switch to the kill wire or you wont be able to turn off the engine. Buy Ram-Pro Inline Spark Tester, Plug Engine Ignition Tester, 6-12 Volt Fool-Proof Pick Up Coil/Armature Diagnostic Detector Tool for if spark is being sent, the tester will mirror the spark and light up - Find dirty spark plugs, defective points, bad cables or connections, etc. The tip can be made of a combination of copper, nickel-iron, chromium, or noble metals. Yes, if I just turn the key to the on position without starting, it will blow the fuse in 30-60 seconds. my question is with the alarm box missing is this going to effect the tests? 3DEL6U1 3BOS6U1. In the United States, common thread (nut) sizes are 10mm (16mm), 12mm (14mm, 16mm or 17.5mm), 14mm (16mm, 20.63mm) and 18mm (20.63mm). The circuit of this system was similar to the Winterburn patent in that it used a push-pull converted switch mode oscillator for energy transfer to a store - discharge capacitor and conventional contact breakers to initiate a thyristor triggering discharge of the charged CD capacitor. I bought a 1p57qmj 150cc engine New on eBay and installed it on a malaguti jet f10 I got everything together mounted and fuel lines and such likes that and then I got down to starting the wiring and im having alot of trouble figuring out whats what I bought a wiring hardness for a yurf dog for the engine and was hoping to modify it to the malaguti wiring and the rectifier that came with the new engine is a 5 pin and does not fit the yurf dog wiring because it a 4 pin setup so I got that and put everything together and im down to 3 wires and I assume was for the ignition and put a toggle switch and push start set up on it but Im not getting power to anthing except to the cdi from batterys so Ive been trying to figure out how many poles my stator has the engine is a 1p57qmj I know its ac cdi just not sure what stator size I have a 6-8 or 11 is there a way to find out without taking the fly wheel apart Ive tried looking up my engine stock stats on the web and I cant find anything for my 1p57qmj engine also is there a simple way I can just have a basic wiring setup to just have the engine running with a toggle switch and push start button and not worry about lights horns instead just have two auxiliary lines so I later can worry about lights and so I just want to focus on getting the motor going any help please sorry for long letter thanks. CDI output: Can be 5% to 30% less than the output from the stator. I have replaced the CDI with the better one and motor ran ok for about 4 starts. Just received brand new B&S #590454 from Amazon seller. Its an inductance shunt. Hi, Ive got a Twister Hammerhead 150cc. The system used an engine driven DC generator that charged a capacitor and then discharged the capacitor through the ignition coil primary winding. i was told the charging system could be doing this. Both mowers resistors failed. distributors that originally had points and condenser, not distributors with Replaced coil, cdi and stator. Do the older ones have a switch? If so, see below: 2. 1. Theyre usually marked with I, II, III for 1, 2, and 3. boost. Some were direct copies of the Winterburn circuit. Maximizing pressure will also produce the best engine efficiency, which translates directly into better mileage. Output ac voltage from cdi to coil peaks at 50 I am using a digital multimeter. Clearance to magnet is .010 What could I have screwed up? Shorts through the rectifier on these models arent very common; the problem is likely a wire connection having unraveled and is now touching a metal surface. This is a brand new out of the crate engine. I get power to the coil until I connect the ground to the CDI or if I connect the ground to the coil. If it has the F/N/R trans with reverse then you have the DC ignition system. Unfortunately, its also, one of the most common types of engine problems. In recent years, you may have heard of cars that need their first tune-up at 100,000 miles. [citation needed], In 1860 tienne Lenoir used an electric spark plug in his gas engine, the first internal combustion piston engine. vehicles, boats, etc. distributor), Ford (Europe, with So I took that coil off and put it on the one that had been running. Also, the 2.5-5 Kohm resistance is for one winding. 1. Buy NGK # 6509 Iridium Spark Plug LTR6IX-11 - 6 PCSNEW: Spark Plugs Ignition Coil Pack Set of 6 - Compatible with Ford, Mercury, Mazda & Lincoln Vehicles - 3.5L, 3.7L V6 Edge, F150, Explorer, Mustang, Taurus X, MKZ - Replaces 7T4E-12A375-EE, DG520, 7T4Z12029E, DG-520 Shop with Points; Credit Card Marketplace; Reload Your Balance; Correct the leads and replace the fuse and you should be good to go. maintenance-free. Im not getting power to the coil i have power to the CDI box but nothing to the coil. timing again, Fits completely under the distributor Thx! electrical system. I did a continuity beep test at this green wire in the on and crank position It has continuity to ground. Is 9 Ohm excessive? Conversion Kits for Here is the shocking part. Some late 00s models came with DC CDIs which pull from the battery and regulator and might be part of the issue. Some otherwise ie brake applied, trans in neutral etc. In this case is the electronic trigger in the coil toast and would that cause the spark to fire MUCH too soon? Good luck I hope this also solve someone else s problem. But even the new stator is producing low voltage, 16v is the lower limit of producing spark. Now no spark with that coil!. Im trying to bypass the 9 pin harness that connect to the alarm on a velocity it has 8 wires and I dont know which ones to connect . However, above idle, it misses and makes no power. Porsche You say here that the kill wire should read 0 ohms to the frame. If you can stand a little shock, then here it goes. item for more information: Electronic Ignition Conversion Kits for Bosch Distributors If you just tap the start button as its dying it energizes the ignition and it fires again but then continues to die. That leaves the kill wire that goes to pin #5, which youll have to trace from the switch in the dash. Then would not crank again. I dont see that in your troubleshooting. Again I guess this points to the CDI. I have what I believe is a Hammerhead 150 with F/R and twin chain. They dont seem to be frayed or touching anything. Motorcraft, External Ballast Resistor: If the charging system voltage, measured at the Appreciate your keeping this thread alive, and all the help offered. Finally, have someone crank the engine and watch for spark. Revs slightly but as soon as rpms get past about 1500 it dies. Engine Bottom End Know The Parts Inside Your Engine, Crankshaft Camshaft Position Sensor Testing The Easy Way, The fuel pump runs continuously while your engine is running, delivering high-pressure fuel, to the fuel rail and injectors.
