The secondary ignition system circuit is; between the ignition coil and the spark plug.

So, a secondary ignition circuit consists, of three components.

The three components are:

So, over the years, secondary ignition systems have changed. Consequently, 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.

The electronic system has an (ECM); controlling the opening and closing of the primary circuit. As a result, this means that the cam in the distributor; which often wears out, could be removed. As a result, these systems create a stronger spark.

So, the distributorless ignition systems; benefit from not having moving parts.

As a result, removing common issues like:

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

Consequently, the distributor is replaced with an (ECM); an ignition control module and; a magnetic triggering device. In contrast, that opens and closes the circuit. As a result, the current is sent to coils, connected to one or two spark plugs. Furthermore, the timing is also controlled.

So, problems in the secondary circuit; could cause issues with the ignition. Furthermore, problems in the primary circuit or; the fuel injection system, could also affect the ignition. So, it is necessary to use an oscilloscope and a secondary pick-up probe; to confirm problems in the secondary circuit. Remember that the secondary circuit, has high-voltage current running through it. So, keep safety guidelines in mind when working with this.
