Why does my scooter have no spark?
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. Some GY6 vehicles like the Yerf Dog GX150 have only one switch, but most others have two. The bypass process is the same.
Why does my 50cc Scooter have no spark?
If it’s shot you won’t get spark either. It’s a black box connected to the coil. Return to Q&A Archives – Won’t Start. A battery tender like the Battery Tender Jr. can make all the difference in whether your scooter will start right up each spring, after being stored for months.
What could I be overlooking as why my 50cc Scooter has?
Tested stator… has output while cranking of 30 a/c volts to the coil, but coil doe not trigger spark. I have replaced coil twice and still same effect, checked all grounds and stator resistance looks OK. What I could possibly be overlooking?
How to troubleshoot a GY6 150cc engine with no spark?
A simple type of crankshaft position sensor. Sends a signal to the CDI to let it know when to send fire to the plug. Set your multimeter to read in VOLTS “AC”. Locate and disconnect the Black/Red and Blue/Yellow wires coming from the stator, where they plug into the main engine harness. (These are both bullet-style connectors)
Where is the CDI on a 50cc Scooter?
It’s a little box located just above and to the left of the flywheel/stator. If that’s bad it won’t send the signal to the ignition coil to fire. If you find the model number in the manual or on the title, putting it in the field in google will bring up scooted sites, many have a wiring diagram for you to look at. where’s my CDI?

What to do if there is no spark in the ignition coil?
Just like before: while cranking the engine, use a multimeter to check for voltage at the two primary wires of the ignition coil. Connect your back multimeter lead to the black ground wire at the coil, and with the red lead to the lighter color wire (usually blue or purple, but it varies).
