What makes a tfi module overheat?

A TFI (Transistor-Fired Ignition) module can overheat due to several factors, including poor electrical connections, inadequate grounding, excessive resistance in the wiring, or a failure in the ignition coil. High ambient temperatures and prolonged operation under heavy loads can also contribute to overheating. Additionally, if the module is not mounted properly or if there’s inadequate airflow around it, heat dissipation can be compromised, leading to overheating issues. Regular maintenance and ensuring proper installation can help mitigate these risks.
