Moped cdi box problem

A CDI box is used in motorcycles and other vehicles to store electrical energy and deliver it to the spark plugs to ignite the air-fuel mixture in the cylinders. If your moped cdi box problem is not starting or running properly, one of the first things you should check is the condition of the CDI box.

The CDI is like a computer as it controls the engine of your scooter. It instructs the fuel injectors when and for how long they should spray. It also directs the spark plugs on how to perform especially when they have to fire. The CDI goes bad because of different reasons. Some of them go bad because they are old, others experience a wiring short while others go bad because of a faulty charging system. The CDI in your scooter is linked to the ignition. Therefore, if it is in good condition then you will have fewer or no issues with your ignition.
