The causes that make the CDI motor damaged can vary. Starting from the spark plug, coil or other problems. But in general, Capacitive Discharge Ignition or CDI is damaged due to unstable electric current voltage.

CDI itself is one of the important components found in motorcycles, especially in the electrical system. So, if the Capacitive Discharge Ignition is already weak, then the motorcycle will also have problems.

The Cause of Damaged Motor CDI Here’s How To Overcome It

The function of this CDI is part of the motorcycle electrical system. Its role is very important, because to control the small size of the ignition process on the spark plug when the combustion process occurs.

If this one component has a problem and cannot operate normally, then you can be sure that your motor will not be able to start or turn on the engine.

In addition, problems due to a dead CDI will also cause the system or other electrical components to be damaged.

But unfortunately, even though the effect or impact is very large, it is very difficult to find the cause of the motor not starting whether it is due to a damaged CDI or not. The reason is, sometimes even though there are problems, these components can still function normally as usual.

Well, if the motor has a problem because the CDI is already weak, then before replacing it, you must first know the cause of the damaged motor CDI.

So, when you replace the Capacitive Discharge Ignition with a new one, then such an incident will not happen again.

Weak battery

The cause of damage to Capacitive Discharge Ignition, usually occurs because of other supporting components that initially experienced problems.

As we know that the DC type CDI current source is from the battery. Usually, a damaged CDI can be due to an unstable voltage on the motor.

One impact if the battery is not functioning normally, then the electric current that enters the CDI will also be unstable. That’s what causes the CDI motor to be weak and even damaged.

Basically, Capacitive Discharge Ignition on the motor does not need special care. But the most important thing is to pay attention to the condition of the battery.

So, make sure the condition of the battery remains optimal. And if it is weak, then quickly replace it with a new one. This is so that the CDI works optimally.

Troubled Spark Plug

The cause of a damaged motor CDI in addition to a weak battery, it could also be due to other supporting components such as problematic spark plugs.

Troubled spark plugs are generally due to the length of use. So that makes the ignition process on the motor to be small.

Meanwhile, to test the spark plugs are still normal or not, you can observe it by seeing whether there is a spark or not when you draw the gas.

In addition, another indication is that the spark plug isolator system will also affect the size of the combustion system process. Because, if the spark plug insulator breaks, then the combustion process will experience interference. This results in incomplete combustion.

One solution to overcome this problem so that the CDI can be more durable is to replace the spark plugs with new ones.

The Coil Is Broken

In addition, the cause of a damaged motor CDI can also be due to a problem with the coil. Damage to the coil can affect the working system of the CDI component itself.

While the general indication that occurs when the coil is problematic, namely the quality of the spark from the combustion chamber will decrease.

So, if you find a problem like that then don’t just ignore it. Immediately replace the component with a new one, so that the problem does not spread to other parts. Including one of them is a motorcycle CDI system.

Spool Troubled

Another cause of damaged motor CDI is still sourced from the electrical component, namely the spool. This component is important, because its function is to provide voltage or ignition to the AC CDI.

So, if a problem occurs, the usual signs are the appearance of a scorch when starting the motorcycle.

Therefore, it is not strange if the voltage that the spull produces will decrease or weaken, when it will channel to the CDI.

If this happens, then you can be sure that the CDI will most likely be damaged. Because, the voltage that comes from the spool will not be maximal.

Now, if you have found the cause of the damaged CDI motor, such as from the battery, spool, spark plug or coil, then immediately replace it with a new one. (Adi/R5/HR-Online)
