The secondary ignition system consists of, everything between the ignition coil and the spark plug.

But, it all starts at the coil, because its the primary side, that makes the secondary side work.

So, coils and spark plugs, have evolved over the years. But, its what’s between them, that has changed everything.

Above all, the secondary ignition system, has made vast improvements over the years. In other words, to make the systems more, reliable, durable and adjustable, to suit the needs of modern engines. These days you can get both, electronic ignition systems and distributorless ignition systems.

Meanwhile, the electronic system, has an (ECM), to control the opening and closing, of the primary circuit. As a result, this allowed you to, not have a distributor. In addition, these systems also, create a stronger spark. So, the (DIS) system, benefits from not having, any moving parts. In addition, the (COP) system, does not have a distributor. (Secondary Ignition System)

This removes common issues like:

  • Engine drag, because of the distributor’s size
  • Timing adjustments
  • Starting problems, due to moisture in the distributor

Today, we use an (ECM), an ignition control module and a, magnetic triggering device. And, are also used to, open and close the circuit, along with the timing adjustments. (Secondary Ignition System)

So, problems in the secondary circuit, could cause issues with the ignition. In addition, any problems in the primary circuit or the fuel injection system, could also affect the ignition. Remember that the secondary circuit, has high-voltage current running through it. So, keep safety in mind, when working with this.

Ignition Coil Failures, (Secondary Ignition System)

So, when a coil fails, it is possible the electricity created, is unable to reach, the spark plug. And, when this happens, the electricity created, looks for the path of least resistance to ground. Furthermore, this path is commonly found, through the boot or body of the coil. So, carbon tracking happens when oil, dirt, or moisture attached to the boot or insulator, creates a path to ground. Consequently, when carbon tracking is found, the coil and corresponding plug should be replaced. Finally, it is also possible that a failed ignition coil, can damage the engine computer, or ignition control module.
