Very often this could be caused by a low battery or poor connection between the battery and starter.
Why is my CDI CDI battery not working?
If no lights coming on in the dashboard and no other electrical consumers work, the battery could be completely dead or there is no connection between the battery and the vehicle electrical system. Check if the battery terminals look tight. If the battery is completely dead, jump starting might help.
What do you need to know about CDI circuit?
Circuit Description Now let’s learn the CDI circuit operations in detail with the following points: Basically as the name suggest, ignition system in vehicles refers to the process in which the fuel mixture is ignited for initiating the engine and the drive mechanisms.
How does a capacitive discharge ignition ( CDI ) circuit work?
The basic working of a CDI unit is executed through the following steps: Two voltage inputs are fed to the electronic CDI system, one is high voltage from the alternator in the range of 100 V to 200 V AC, other is a low pulse voltage from a pickup coil in the range of 10 V to 12 V AC.
What happens when you turn off the CDI on a motor?
When we want to shut down the motor engine, we have two switches the key switch or the kill switch. The switches ground out the charging circuit so the entire charging pulse is sent to the ground. Since the CDI can no longer charge, it will cease to provide the spark and the engine will slow to a stop.
Why is my Mercedes C220 CDI not starting?

How does a capacitor discharge ignition ( CDI ) system work?
Working principle a CDI System. A capacitor discharge ignition works by passing an electrical current over a capacitor. This type of ignition builds up a charge quickly. A CDI ignition starts by generating a charge and storing it up before sending it out to the spark plug in order to ignite the engine.
