Each cylinder has its own miniature ignition coil. The plug is connected to the high voltage generated by an ignition coil or magneto. An example of an autotransformer is an automobile ignition coil. Opening the points causes a high induction voltage in the system's ignition coil. Inside the ignition coil one end of each winding is connected together. The ignition coil used is the E-Core design. Originally, every ignition coil system required mechanical contact breaker points and a capacitor (condenser). This ignition coil design is more efficient than the older-style cylinder-shaped ignition coils. Ignition coil and fuel injector problems have been reported on models using the N43 engine.
