One of the worst things a snowmobile owner experiences is having no spark when trying to start the snowmobile.
When this happens, the causes of no spark on snowmobile has to be checked.
Some of the things that causes no spark in a snowmobile are bad spark plug, bad spark plug cap, bad ignition coil, bad CDI box and bad stator in the snowmobile.
Due to this, the reason for the no or weak spark in snowmobile may be a minor problem if the fault is from the plug cap.
But it could be a major problem if the cause of the weak or no spark is from a faulty major part like the stator in the snowmobile.
This will cost more to fix the issue as compared to few dollars to replace a bad plug cap.
But irrespective of the cause of the problem, a faulty part has to be repaired.
This will give life back to your snowmobile.
Causes Of Weak Or No Spark On Snowmobile
1) Bad Plug Cap
When there is no to little spark in a snowmobile, it might look like a very big problem to a lot of people.
But the thing is that in a lot of the cases when this occurs, it is usually due to the fault of a minor component of the snowmobile.
That is why adequate troubleshooting is necessary when this occurs.
This will help you know what is really causing the problem in your snowmobile.
In a lot of times, the reason why there is no spark in a snowmobile is always caused by a bad plug cap.
For a spark to take place in a snowmobile, voltage has to be transferred to the spark plug.
In this process, a lot of components of the snowmobile play a vital role here.
Such components include the ignition coil as well as other parts like the CDI box.
But irrespective of this, there is still a component that transfers this charge to the spark plug to help produce a spark.
This component is no other than the plug cap.
The plug cap helps deliver the charge to help the spark plug function well.
When it develops a fault, this will cause the spark plug not to produce a spark.
One of the ways in which a spark plug cap may be bad is when it has a loose contact with the spark plug.
This will lead to a weak spark on the snowmobile.
At worse cases, it will even lead to no spark on snowmobile.
2) Bad Ignition Coil Cable
For the spark plug cap to function, a wire has to deliver the high voltage from the ignition coil to it.
This is made possible with the help of the ignition coil cable.
This is just a wire that connects the ignition coil to the plug cap.
A problem can set in sometimes when the cable has a problem.
This could be issues like a rodent eating the cable.
Apart from that, if the cable is of a low quality, it can easily get faulty.
This will cause a problem to the snowmobile when the cable of the ignition coil is bad.
The way this will happen is that it will not help deliver the voltage from the ignition coil to the spark plug cap to help the spark plug make a spark.
3) Faulty Ignition Coil
For a spark to be generated in the spark plug of a snowmobile, one of the vital components that help in this process is the ignition coin in the snowmobile.
The ignition coil in a snowmobile helps deliver the right voltage to the spark plug through the spark plug cap.
This is what helps the spark plug to produce the right spark.
Due to this, the fuel in the cylinder is easily burnt to help generate power.
But when the ignition coil is bad, a problem will also set in too.
This can lead to cases of having a weak spark on snowmobile.
Due to this, the combustion of fuel in the cylinder of the snowmobile will not be possible due to inadequate spark from the spark plug.
4) Bad CDI Box
The CDI box is a very essential component in a snowmobile.
It performs a lot of duties in the snowmobile and can render a snowmobile useless when it develops a fault.
This is because of the role that the CDI box plays when it comes to the production of spark in a snowmobile.
The CDI box helps in storing electrical charges in the capacitors.
This helps discharge the charges through the help of the ignition coil to the spark plug.
Due to this, it helps the spark plug to produce a powerful spark powerful enough to burn the fuel in the cylinder.
But when the CDI box in a snowmobile is faulty, then the snowmobile spark plug will find it difficult to produce a spark.
This is one of the causes of no spark on snowmobile.
5) Bad Snowmobile Stator
When you discover that you are having a weak charge on your snowmobile, one of the components in the snowmobile that can cause this is the stator of the snowmobile.
The stator in a snowmobile is a very important component when it comes to the electrical functions of a snowmobile.
For a charge to be generated to the spark plug of a snowmobile, a component helps to make this possible.
This is when the stator in a snowmobile plays a very vital role.
In a snowmobile, the stator is responsible for producing the electrical current that is used in the snowmobile.
This electric current is what feeds other components like the ignition coil to amplify the charge before sending it to the spark plug through the spark plug cap.
When the stator in the snowmobile develops a fault, it will not be able to generate the current that is to be used in the snowmobile.
Due to this, other parts like the ignition coil that helps the spark plug to generate an efficient spark will not function.
Due to this, there will be no spark on snowmobile.
6) Bad Spark Plug
For a spark to be produced in the engine cylinder of a snowmobile, the component that does this job is the spark plug.
With the help of other components in the snowmobile like the stator, CDI box, Ignition coil and the spark plug cap, the spark plug generates a spark.
This spark helps to ignite and burn the fuel in the engine of the snowmobile so that power can be produced.
But sometimes you can run into a situation in which there is a weak or no spark in the snowmobile.
One of the snowmobile components that causes this is the spark plug in the snowmobile.
When the snowmobile spark plug is bad, it will not be able to produce spark.
This is one of the causes of no spark on snowmobile.
But to determine if the spark plug is the cause, a troubleshooting has to be done.
If after that you discover that the spark plug is the cause of the problem, you have to make sure that you change it.
In changing the spark plug, make sure that you replace it with a good one from a reliable brand.
