The ignition coil steps your battery voltage up to the thousands of volts needed to jump the plug gap. A weak or breaking-down coil produces a misfire under load, hard hot starting, and a spark that fades at higher rpm. A fresh coil delivers a strong, reliable spark across the range. Confirm the primary resistance and connector type against your original.
