1. Overheating: Briggs and Stratton engines are known for generating a significant amount of heat during operation. If the engine is not properly cooled, the coil can overheat and fail.
2. Improper Installation: Ensure the coil is appropriately mounted and secured. Loose or improperly installed coils can vibrate excessively and fail.
3. Incorrect Wiring: Make sure the coil is wired correctly according to the manufacturer's instructions. Incorrect wiring can cause the coil to malfunction.
4. Electrical Issues: Check for any electrical issues in the engine, such as short circuits or loose connections, which can affect the coil's performance.
5. Quality Issues: Some aftermarket coils may not meet the same quality standards as the original Briggs and Stratton coils. Using low-quality coils can lead to premature failures.
6. Water Ingress: If the engine is exposed to water or excessive moisture, it can seep into the coil and cause internal damage, resulting in failure.
7. Fuel Mixture: Ensure you are using the correct fuel mixture for your Briggs and Stratton engine. An improper fuel mixture can lead to overheating and engine damage, which can negatively impact the coil.
8. High Resistance in Electrical Components: Corroded or damaged spark plug wires, fouled spark plugs, or improper grounding can cause higher electrical resistance in the system. This can lead to excessive stress on the coil and cause it to fail.
9. Improper Air Gap: Ensure the air gap between the coil and flywheel is set according to the manufacturer's specifications. An incorrect air gap can affect the coil's ability to generate the necessary spark.
10. Old or Worn-Out Coil: If the coil has been in use for a long time, it may naturally deteriorate and need replacement.
If you've addressed the potential causes mentioned above and the coil still fails, it is advisable to contact Briggs and Stratton customer service or an authorized repair center for further assistance.
