Which component transfers high voltage from the exciters to the igniter plugs?

• A. FADEC
• B. AVM
• C. Igniter Plugs
• D. High Tension Leads

Answer: (D)

In an ignition system, the high voltage generated by the exciter must be carried to the spark plugs without loss or breakdown. The component that does this is the high-tension leads—the insulated, high-voltage cables that connect the exciter to the igniter plugs and deliver the precise, rapid pulse needed to ionize the air and create a spark. These leads are designed to withstand the high voltage, resist arcing, and maintain the correct impedance for a reliable spark across a wide range of operating conditions. FADEC is the engine control computer and does not transmit high voltage to the plugs. Igniter plugs are the end points that produce the spark, not the transmission path. AVM (if present) is a voltage monitoring device, not the conductor of the ignition energy.
