The role of the ignition coil is to multiply battery voltage into high voltage. Following Ohm’s law for the conversion of volts to amperes, oil-filled coils generally require 3 to 5 amperes of primary current to produce 20,000-30,000 volts of secondary current. Modern E-core and COP (coil-over-plug) ignitions require as much as 7 amperes of…
