Thx! Buggy Depot Select your vehicle. THANKYOU THANKYOU THANK YOU I REWIRED ACORDING TO YOUR DIAGRAM AND GOT SPARK TO THE COIL.NOW I AM WORKING ON GETTING IT OUT THE COIL.I HAD TO REWIRE THE GY6 BUT SO FAR SO GOOD .B. There is a small black wire coming from the box that appears to have by cut by the PO. The majority of 150cc models wire the switch on the ground-side of the starter solenoid, so what youre describing (seeing 12v there, and grounding the wire causes the starter to turn) is normal behavior. Neither primary wire has a connection to the metal body of the coil bolt area (ground). I rode up in to the garage and shut it down. If you have an OBD-II diagnostic scanner, you may see a P0351 ignition code. Usually leaves a pea-sized bump mark in the back of the CDI casing where the internal capacitor is located. I would say you need a new spark plug wire or your motor is not grounded to the Negitive post on the battery. However the last time I did this I inadvertently touched the wire to the frame to kill the engine. While cranking the engine, use a multimeter to check for voltage coming from the Red/Black (CDI power wire) and the Blue/Yellow (trigger wire) coming from stator. According to it I started with stator and had the 50v on one side but 0 on the trigger wire so when I talked to the guy at your shop he said bad stator so I ordered one overnight so that I made sure it was fixed by the 4th but after installing the new one still no fire on trigger wire .I have double checked the switch and the kill switch ..now what Help Can you help me please? Checking both primary connections is where to start. Step 4: Check the coil. Set your multimeter to read resistance (ohms). Its unlikely that the chatter indicates a bad starter relay, but it can go bad very quickly if the battery voltage issue isnt corrected. Black is neutral, green is input from the CDI. Step 1. Questions: so i replaced the coil with a stock one thinking that was the issue, nogo. Ignition system testing, Magneto coils, Points and CDI. 1.7 ohm I also tested the Pinout's pin 1. input from trigger .01 2 to ignition coil 0 pin 6. cdi power from stator. So, maybe its in the plug?? Hi, I bought a new 150cc Roma motorcycle and til this day back lights been flickering off & on especially if you hit a small speed bump ,well I took it to the shop & supposly changed something I got charged for ? There should be between 20vAC ~ 100vAC coming from the CDI power wire (Black/Red), although much lower voltages will still be able to produce spark. Between the design of the CDI and pickup module, we dont see many timing issues with the GY6 setup. Read the comment above yours about how the trigger wire/circuit works.

I put the coil ground to the engine frame. Normal voltage from the stator is normally anywhere between 60v 120v. Hi Ryan, Then, remove the fuel tank, and maybe even the bike seat, to access the coils and spark plugs. What model number and year (if you know) is your Twister Hammerhead? Invention prototypes are another of his many accomplishments. I have replaced the cdi, coil, plug, stator and still no spark. Use your multimeter to take a reading directly from this wire, stator side. Will High Performance Motorcycle Spark Plugs Decrease Gas Mileage? My GY6 has new stator w/pickup, CDI, coil and carburetor. CDI is New Install the plastic cover over the coils, mount the fuel tank and tighten the mounting bolts. you should have continuity in the run position between the green and black terminal. ie brake applied, trans in neutral etc. center terminal and the other lead to each of the outside terminals. Is a copyright claim diminished by an owner's refusal to publish? 22.5 v . When I turn the key on I get 1 spark and thats it. My confusion with it is the Manual says in Step 1: "Disconnect all ignition coil wires (including the spark plug leads) before testing." Than it says to test the primary circuit. Write the voltages down and continue to the next step. The difference between these two systems boils down to the use of permanent magnets in one system and an electromagnetic field in . I recently replaced the Stator CDI and Coil and still no spark. We have replaced the cdi, stator, pick up, coil, I have checked grounds and they SEEM good (any failsafe way to check these?). You can also check the gap between the coil and the magnet. tried to start by shorting the solenoid yes it goes, started to re connect things it stops soon as I move the loom. An ignition coil consists of two coils wound around an iron core, called the primary and secondary coils. Bill, are you using a digital multimeter to test your stator, or is it an analog type (with needle)? 2 to ignition coil 0 I have some symptoms similar to most of the enquiry above. I have a 150cc dune buggie when I try to start it it turns over but doesnt start what is the problem. Except no spark. 2. The most sensible place to begin is with your car in park, and the engine switched off. I have replaced everything and did the steps offered still no go. Since I have had it, it runs like crap Bogs down with just a little trottle and backfires like crazy, thinking it was a fuel issue I went a head and replaced the carb, so it is still doing it so now my thinking is misfiring, is there a way to check/ adjust the timing? 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. Pin 5 should not read any resistance to ground using an ohm meter. How can I obtain a book for parts? To test the operation of both the ignition coil and the spark plug, connect the tester between the spark plug boot and the spark plug. since I removed it after and it still runs, but your suggestions were well designed and very understandable Ensure that the spark plug is gapped properly.Recommended spark plug gap: 0.6mm ~ 0.7mm (0.23 ~ 0.27). 5. Replaced so far: CDI (two times), coil, spark plug, trigger. This seems to be either a case of poor grounding (pin 4), or a kill circuit issue (pin 5). Copy. In other words, the ignition coil works like a transformer. We and our partners share information on your use of this website to help improve your experience. It is very comparable in design to the pulse transformers used in other appliances such as fence chargers, well suited for high voltage bursts.

Coil test. Im not familiar with the ignition system on 250cc class buggies. Ignition Coil (New) = 30VAC, 0 ohms (analog). If you look at the pinout above, it is pin 6. 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. Now, start the vehicle and run for several minutes. If you keep tapping the start button you can get it to rev high. The minimum we have seen working is around 18vAC. Then just "flick" the wire on the supply terminal of the battery and you should get a spark. Hi, Ive got a Twister Hammerhead 150cc. Your next step is to pull the #6 coil you just moved and replace. Whats up with that ? An Electric diagram would help finding a blown fuse. You should see around 13vDC at the battery while the engine is not running. Lines are New. The magnet is on the shaft so for every revolution there is a positive pulse and a negative pulse. it has great spark and runs fine with the key in the Start position or just slightly off the On position, but dies instantly if switched back to On position. Turn off the motorcycle ignition. What is the right Stator? Disconnect the blue/white wire from the stator. I am a mechanic, but we all get stumped and all data dont cover gy6 engines. Tried it with the new CDI and the old CDI. Thanks a bunch for your help and comments. 1. Ground to pin #4 Hey all Travis told me to post my results here. https://www.buggydepot.com/product/404/cdi-connection-kit-pigtail.html. But with it disconnected from the CDI it doesnt matter anyway right?
