generator, and the battery is helping to supply electrical power. This may mean the alternator or generator is malfunctioning, or the electrical load is excessive. An ammeter displays the load placed on the alternator or generator by the electrical equipment ... unless a short or the overload still exists. In this case, the circuit breaker continues to pop, indicating an electrical malfunction. A fuse simply burns out when it is overloaded and needs to be replaced. Manufacturers usually provide a holder…

LEFT selected, only the associated magneto is activated. The system operates on both magnetos when BOTH is selected. A malfunctioning ignition system can be identified during the pretakeoff check by observing the decrease in rpm that occurs when the ignition ... ignition switch is left ON and the propeller is moved because the magneto requires no outside source of electrical power. Be aware of the potential for serious injury in this situation. Even with the ignition switch in the OFF position…
