How does the ignition coil work on an ATV?
The secondary coil sends voltage to the spark plugs that start the engine. Each coil has a specific operating resistance specified by the manufacturer. This resistance prevents too much electrical current from passing through the wire, so the correct voltage may be reached by the ignition pickup coils.
How can I tell if my ATV engine is sparking?
To quickly tell if your ATV is getting spark, remove the spark plug from the engine. Reinsert the plug back into the coil wire. Hold the electrodes of the spark plug close to the engine to ground it, and try starting the engine. If you see spark coming from the end of the spark plug, your ATV engine is getting spark.
Where does the spark come from on an ATV?
Reinsert the plug back into the coil wire. Hold the electrodes of the spark plug close to the engine to ground it, and try starting the engine. If you see spark coming from the end of the spark plug, your ATV engine is getting spark.
What causes a spark plug to go bad on an ATV?
Whether the spark plug gapping is incorrect, the plug has gone bad, or it’s the wrong plug altogether for your engine, it may no longer be able to provide a spark. Note that a spark plug may physically look fine but still have gone bad.

What happens to ignition coils on snowmobiles?
Here’s a quick walk through video to test ignition coils in snowmobiles: Just like the name implies, this part of the snowmobile rectifies and regulates voltage. If the rectifier/regulator is faulty, power will become irregular throughout the electrical system.
What does CDI stand for on a snowmobile?
CDI stands for capacitor discharge ignition. The CDI box is responsible for the spark igniting in the engine through a spark plug and ignition coil. The CDI box works by storing electrical charges on capacitors and discharging the charges through an ignition coil so that powerful sparks get produced.
