Inductance concepts The transistor switches are contained in a solid- state Ignition Control Module. Modern coil designs produce voltage pulses up in the neighborhood of 40,000 volts from the interruption of the 12 volt power supplied b the batter . Add more annotation to coil diagram Some modern engines have multiple ignition coils mounted directl on the sparkplugs. Instead of single voltage pulses, the ma under some engine conditions produce three voltage pulses. The coil arrangement shown is on a Dodge engine.
