What are the reasons for weak spark in the Cerato ignition coil?

[DiDallas]

The reasons for weak spark in the Cerato ignition coil are insulation layer aging breakdown or switching transistor damage. Here are the relevant explanations: 1. Insulation layer aging breakdown or switching transistor damage: Large spark plug gap will cause heavy load on the main coil, generating more heat and accelerating insulation layer aging. Small spark plug gap will cause large discharge current in the secondary coil, generating heat quickly and accelerating insulation layer aging. Assembled ignition coils may have poor durability of insulation materials, high internal resistance generating heat quickly, and transistors of inferior quality may have shorter lifespan. 2. Extended information: The ignition coil consists of main coil, secondary coil, magnetic core, switching transistor and other auxiliary components. The main coil is charged by the battery, the secondary coil discharges to spark the plug, and the transistor is responsible for switching.
