The cc GY6 ignition system is fairly easy to troubleshoot in the case of malfunction.

There are 4 major components that work together to produce spark, if any of these are defective spark will be lost. What we will be doing here is troubleshooting these ignition parts starting at the source, and working towards the spark plug. To diagnose your ignition system, you will need to do each of the steps in this article, in sequence.

Before getting started, take a look at this diagram. Although there are many differences in wiring between models, most GY6 ignition systems work the same as shown in this illustration. A very common cause of no spark is a defective ignition or kill switch.

Before beginning to troubleshoot ignition problems, it is best to bypass the switches. Note the wrapped ignition winding, and trigger module. Ignition Winding: Depending on your stator type, you have either 6, 8, or 11 windings.

Of these windings, one is dedicated to supplying the CDI with ignition power. This winding is usually wrapped in white cloth material and sealed over with clear epoxy.

Trigger pickup: A simple type of crankshaft position sensor. Sends a signal to the CDI to let it know when to send fire to the plug. This current is stored in a capacitor within the CDI unit.

When a signal is received by the trigger pickup passing over the flywheel magnet, the CDI will discharge the stored energy into the wires leading to the ignition coil. The minimum we have seen working is around 18vAC. Black is neutral, green is input from the CDI.

The function of the ignition coil is to multiply the voltage of the power supplied from the CDI, and to send the multiplied power to the spark plug. Troubleshooting the Ignition Coil: Check for 0. The best way to tell if the coil is bad is to perform steps the steps above.


If there is still no spark, the coil is likely bad. The plug is very rarely the cause of no spark on the GY6. If the plug is fouled or cracked it may not spark. Ensure that the spark plug is gapped properly. Recommended spark plug gap: 0.

Thank you. I have no spark and replaced plug and wire getting a stator and trigger and cdi what else could it be? Where does the black and red wire plug in at. Mine spins over but will not fire an the red and black wire is not connected to anything. This is the CDI power wire. I have a jet moto automatic atv. I purchased it not running. There is no spark.

I have done dome digging and found it is the gy6 engine with the DC ignition. I have replaced the battery, DC cdi, ignition coil, and tried a new stator. Still no spark. I ran a ground from 4 on cdi to engine. And checked the handlebar switches. Cdi in 6 from battery 12vdc. Cranking voltage out to coil from Cdi. Your email address will not be published.

Buggy Depot. It is coming out of the stator but not connected to anything else. It is a 6 pole unit. I am at a loss as to what to try next. Can anyone help? I have a Yerfdog Howit cc LY6 model. Does the GY6 engine wire harness match the LY6? Travis Buggy Depot. Justin jones.

Leave a Reply Cancel reply Your email address will not be published.Stop asking me for wiring diagrams for scooters. The wire guide features an 11 pole stator and five wire CDI, but it should be helpful during any GY6 swap. Click for full size. One tip: find out if your vehicle is called something else in other countries.

For example, the Ruckus is called the Zoomer in Japan. Try that. July 10, at pm. I have an 08 Metro and threw a rod, so I ordered a cc long from t-motorsports lousy company for support and I fabricated my motor mount and shock extender.

I have the motor mounted and wondered if it is possible to take the wires coming from the engine they go to the stator and splice them into the existing electronics from honda. Another words, do i need to use the CDI, rectifier, ect that came with the motor. It seem it would be easier to use the Honda wiring and just splice the stator wires with it.

Then run a hot wire for the solenoid and connect the yellow and green wires from the solenoid to the starter relay. Anyone know if this sounds possible? July 11, at pm.

April 4, at am. July 15, at pm. Thanx for all your hard work. I ordered my 11 post stator today and hope to get it monday or tuesday. I have a question about the CDI. How does anyone know which pin is which? I can email you a photo or send by text if you can help me with this one. July 16, at pm. It came with the engine from t-motorsport but the gave no paperwork and when I email or call the, they are clueless. Could you answer a couple more questions? First, on the CDI pic, could you attach the wire colors from your big drawing I assume AC ignition is Blue and trigger pulse is black to the relay.

Also, the engine I ordered came with CDI, 5 wire rectifier, coil, and I think a flasher; do I use the factory Metropolitan relay and if so, does it need to be changed at all? Do I connect the multiple yellows from the stator to the single yellow on the rectifier or do I need a different rectifier?

When you have that CDI, you can just use the wiring diagram I made. As for the rest of your questions, they have all been covered in detail on totalruckus. If you still have specific questions, let me know. You are not coming off ignorant, but you should continue to research this topic on TR.

There is a ton of information about this on there. July 30, at pm. I finally came to the realization that all my met wiring had to go. I gutted it, bought, 8 post relay like in the drawingnew stator and regulator, and used your diagram and I got the engine to fire. Here is my latest dilemma: after wiring everything and the key turned off or on the relay clicks and turns on the moment I connect the battery. I checked TR and there are 10 different ways people are wiring.

I thought maybe I was looking at the relay from the top instead of the bottom or vise — versa so I re-wired and still the same. Can you offer any help?We are also really excited to start expanding our knowledge base into the newly introduced IceBear Fuerza, Boom and Denali among other Grom clones that are hitting the market.

With the huge variety of bikes we discuss here, it is really important to post the specific make, model and engine size when asking questions ie.

A wiring diagram is a simplified standard pictorial representation of an electrical circuit. It reveals the components of the circuit as simplified shapes, as well as the power as well as signal connections in between the devices. A wiring diagram normally offers details regarding the family member position and setup of tools and terminals on the tools, to assist in structure or servicing the tool.

A photographic representation would reveal extra information of the physical appearance, whereas a wiring diagram uses an extra symbolic symbols to highlight interconnections over physical look. A wiring diagram is commonly made use of to troubleshoot issues and also to earn sure that all the connections have actually been made as well as that everything exists.

A very first consider a circuit layout might be confusing, but if you could review a metro map, you could read schematics. The objective coincides: receiving from factor A to direct B.

Literally, a circuit is the path that permits electricity to flow. If you know just what to look for, it ll become second nature. While in the beginning you ll simply read them, at some point you will certainly start developing your personal. This guide will show you a few of the typical symbols that you make sure to see in your future electric engineering profession. Voltage: Measured in volts Vvoltage is the pressure or pressure of power. This is generally supplied by a battery such as a 9V battery or keys electricity, the outlets in your home operate at V.

Electrical outlets in various other nations run at a different voltage, which is why you need a converter when taking a trip. Current: Existing is the flow of electrical power, or even more particularly, the circulation of electrons. It is measured in Amperes Ampsand also can just flow when a voltage supply is linked. Resistance: Gauged in Ohms R or Oresistance defines just how easily electrons can move via a product.

Materials such as gold or copper, are called conductors, as they quickly permit circulation of movement low resistance. Plastic, timber, and air are examples of insulators, inhibiting the activity of electrons high resistance. DC Direct Existing. DC is a constant flow of current in one direction.
