Why does my scooter have no power?

If you’re riding down the street in your scooter and suddenly it loses power, it’s typically due to a problem with fuel delivery or with electrical spark. Sometimes it can be as simple as a quick short circuit caused by water splashing onto the motor, or the signs of a more complex situation.

Can a CDI box cause weak spark?

Re: reasons for weak spark on CDI system? The COIL can give weak spark in spite of the spark being triggered by a CDI box. If you have an anemic yellowy spark from the plug then I would suggest to check that all of the connections are clean and tight.

Can a bad CDI cause bogging?

An electrical wire or connection that is corroded or broken can cause intermittent bogging problems. Places to check for bad grounds/wires: CDI ignition wiring. Kill switch wiring/connection.

Can a CDI box be repaired?

CDI will repair your ignition component, then test the part to make sure it is performing at an optimal level. CDI Electronics will return the part to you via UPS.

Will a CDI box cause no spark?

Sometimes, a bad CDI does not cause sparks at all. Again, when a CDI box is about to go bad, it can lead to misfires, issues with starting, rough running or even stall the motor.

Cracked spark plug porcelain. This causes misfiring or bucking under load.
Fouled spark plug.
Weak ignition wire insulation.
Weak ignition coil.

Where is the ground pin on a GY6 CDI?

Forget the kill switch, just cut power to the CDI. If you look at the pinout above, it is pin 6. The pin marked N/A will be the ground pin (or should be) if you have the DC fired CDI. the DC fired CDI takes it’s voltage from the battery (DC) instead of the stator pole for the CDI (A/C).

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.

How many windings does a GY6 150cc have?

Don’t use force here. 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.
