If an ignition coil fails in a motor with dual lead ignition coils, what is the result?

In a motor with dual lead ignition coils, each coil is typically responsible for igniting the fuel-air mixture in specific cylinders. If one ignition coil fails, it will directly affect only the cylinders that are connected to that specific coil. As a result, only those two cylinders will experience a failure to produce ignition. The other cylinders, which are connected to a functioning coil, will continue to operate normally, allowing the engine to run, albeit with reduced power due to the loss of combustion in the affected cylinders.

This partial operation is a typical characteristic of systems with dual lead coils, where the failure of one component does not lead to a complete shutdown of the engine but rather a localized effect on only the connected cylinders.
