What Is Ignition Coil A Primary Secondary Circuit Malfunction

When it comes to car maintenance, it's important to know the basics. One essential component of any vehicle is the ignition coil, which is responsible for delivering the spark that ignites the spark plugs and starts the car. But what happens when an ignition coil goes bad? A primary/secondary circuit malfunction could be the culprit.

An ignition coil is a small device made up of two separate coils of wire. The first coil, known as the primary coil, is connected to the car battery and supplies the power necessary to create a spark. The second coil, known as the secondary coil, is connected to the spark plug and receives the spark from the primary coil. When the battery voltage is applied to the primary coil, it creates a powerful magnetic field. When this magnetic field collapses, it creates a current in the secondary coil, which then produces a spark at the spark plug.

A primary/secondary circuit malfunction can occur if either of the coils go bad, causing the car to not start or run erratically. If the primary coil goes bad, it will not produce a strong enough magnetic field to ignite the spark plugs. If the secondary coil goes bad, it will not receive enough electricity to create a spark. In either case, the engine will not start or run properly.

Fortunately, diagnosing a primary/secondary circuit malfunction is relatively simple. Your mechanic will need to use a multimeter to check both the primary and secondary coils. If either of them are not producing the correct voltage, they will need to be replaced. It may also be necessary to replace the spark plugs if they are not working correctly.

In summary, when your car does not start or runs erratically, a primary/secondary circuit malfunction may be the cause. Your mechanic can quickly diagnose the issue with a multimeter and replace the faulty components, getting you back on the road in no time.
