Feature: 1. for YMH 2‑stroke 15‑horsepower ignition coil, composed of primary coil, secondary coil and iron core. 2. When in use, charge the primary coil first, and self‑induct a voltage of 200‑300V in the primary coil; then generate a high voltage of 18‑20kV by mutual inductance with the secondary coil. 3. The magnitude of the voltage generated depends on the turns ratio of the two coils, and finally the high‑voltage electricity is delivered to the spark plugs for ignition. 4. Made of premium rubber and metal material, antirust, anti‑corrosion and durable. 5. standard, direct replacement for the old or broken one.
