Which outcome occurs in a capacitive discharge ignition (CDI) system when the silicon-controlled rectifier (SCR) fails to trigger?

💡 Explanation

When the SCR fails to trigger, the capacitor cannot discharge its high-voltage energy through the ignition coil because blocking voltage remains applied, leading to insufficient spark voltage at the spark plug. Therefore, spark misfire occurs as the capacitor voltage doesn't complete the intended resonant oscillating discharge, rather than continuous spark, coil damage, or fuel starvation which depend on other mechanisms.
