Where does the CDI box amplify the signal?
The box amplifies the small signal generated from the spinning magnet located in front of the pickup coil in the stator, just before top dead center (TDC), when your fuel-air mixture is ignited. The box can’t generate continuous sparks.
How is a CDI box different from an inductive system?
Compared to inductive systems, the CDI box system has a shorter transient response and spark duration. The CDI system produces huge electromagnetic noises that don’t sit well with automobile manufacturers. Its short spark duration isn’t ideal for lighting relatively lean mixtures.
When do I need to replace my CDI box?
If either the primary and secondary windings are different from the automotive specifications, you’ll want to replace your CDI box, as your current one might be damaged or malfunctioning. An engine spark characterizes a faulty CDI box, whereas a well-functioning box doesn’t allow the engine to spark.
Where is the secondary winding resistance on a CDI box?
Touch one of the outer contact leads and central, inner contact of the ignition coil. This is where the main wire connects to the distributor. Record the reading. This is termed as the secondary winding resistance of the ignition coil.

How can I tell if my CDI box is damaged?
The automotive should be switched off and allowed to cool. Use an ohmmeter to measure the electrical resistance of the CDI box in a quantifiable way. Different vehicles have specified electrical resistance within the coil. If the coil’s correct resistance levels fail to meet these specifications, you’ll know that your coil is damaged.
Why is my CDI coil not working on my motorcycle?
This often surfaces when you have an older motorcycle with a CDI ignition and want to place the coils under computer control. Many motorcycle CDI coils will not give a good spark unless you pair them with a multi-channel CDI ignition.
Why does a CDI coil work with an inductive ignition?
With no energy storage requirements, making the coil’s inductance and resistance low lets it transfer the spark energy faster, making for the hot, short sparks that CDI ignitions specialize in. It is possible to design a coil for CDI applications that still has a high enough inductance to work with an inductive ignition.
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.

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.

How does an ignition coil spark generator work?
Each cycle makes a new kick of energy pass through the circuit and thus creates a new ignition spark in the engine each time (and thus creating a steady, continuous set of rapid combustions that allows the car to run smoothly). This used to be done mechanically, but recently integrated circuits have largely replaced physical distributors.

Where does the DC current from an ignition coil come from?
A strong DC current pulse can be generated by a coil below the flywheel because the flywheel magnet goes over it. These DC current supplies throughout a wire toward an ignition coil placed at the external of the engine.
