Does a CDI ignition have points?
The electrical source of this module gets only from the AC generated through the alternator. This is the basic CDI system used in small engines. So, not all the ignition systems which have small engines are not CDI. The whole ignition system, points & coils are below the magnetized flywheel.
Can CDI units be repaired?
CDI Repair specializes in all kind of motorcycle electronic repairs. It is the place to go if you have a problem with your CDI unit as we can test almost any faulty ignition unit. We have successfully tested & repaired over 2,500 ignition systems used in a motorcycle, go kart, scooter, jet ski, trike and powerboat.
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.
What does CDI stand for in a circuit?
CDI stands for capacitor discharge ignition (alternatively, “capacitive.”) If you’re new to capacitors, they’re similar to batteries in that they can store energy for later. What sets them apart is their ability to release all that energy near instantaneously, which is ideal for an ignition circuit.
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.
What are the advantages of a CDI box?
The main advantage of a CDI box is its capacitor’s ability to take the shortest time possible to be charged up. Shunt resistance doesn’t affect the CDI box due to fast electric voltage rising. Compared to inductive systems, the CDI box system has a shorter transient response and spark duration.
How does shorting a CDI ignition system work?
Shorting either one to ground will disable the ignition and stop the engine,in the first case the storage cap does not get charged,in the second it does not get discharged.

What happens if I Disconnect my CDI?
2) The charge coil and trigger coil are fairly robust devices and not likely to fail,measure resistance to ground (disconnect from CDI),if shorted or open circuit,they are defective or leads bad.
