Typically, an ignition coil contains two sets of coils – a primary coil and a secondary coil. The primary coil uses thicker enameled wire, typically about 0.5-1 mm in diameter, wound around 200-500 turns; the secondary coil uses thinner enameled wire, typically about 0.1 mm in diameter, wound around 15,000-25,000 turns. One end of the primary coil is connected to the low-voltage power supply on the vehicle (+), and the other end is connected to a switch device (breaker). One end of the secondary coil is connected to the primary coil, and the other end is connected to the high-voltage output end to output high voltage.
