What are the major components of the ignition system?

• A. High tension leads and sensor
• B. Ignition exciter only
• C. High tension leads, ignition exciter, and 2 spark ignitors
• D. Spark plugs only

Answer: (C)

The ignition system needs three key elements to work: a source of ignition energy, a path to deliver that energy, and the devices that actually create the spark. The ignition exciter provides the high-voltage pulses that start the spark process. The high tension leads carry that energy from the exciter to the spark devices. The spark ignitors (two in this setup) are the actual spark-producing elements that ignite the fuel-air mixture in the combustor. Including all three ensures reliable ignition, even if one component underperforms. Without the igniters, there’s no spark. Without the exciter, there’s no energy pulse to generate a spark. Without the high tension leads, the energy wouldn’t reach the spark devices. That’s why the combination of high tension leads, ignition exciter, and two spark ignitors best represents the major components.
