Car Ignition Coil Output Voltage at Victor Lopez blog

Car Ignition Coil Output Voltage. Coil output is a factor of its turns ratio, primary resistance, and input voltage—assuming it has enough time to fully “recharge” between firing impulses. When your engine is running your coil is drawing 2a from the battery most of the time through the shown switch which is normally closed when the ignition switch is on. The high voltage is carried away from the coil. When cranking the coil should be getting the full battery voltage, but because of the high current through the starter the battery voltage may drop from 12 to 9 volts or less. The high voltage on the secondary coil can be up to 40 kv, depending on the ignition coil. The opening induction voltage of the primary winding is between 300 and 400 v. If your car uses a 12 volt battery, the 12 volts you put into the primary side of the coil will exit the secondary side as 30,000 volts!
