Main Breaker Relay
The main breaker relay (Kissling), located in the cockpit, disconnects the battery from all
the electrical power devices, but it does not disconnect the alternator (and the starter
motor supply) from the battery. In this way the main breaker switch and the emergency
breaker switch will be able to kill the engine if still running. See scheme below.
The connection shown below must be avoided, because it would not allow the main
breaker switch and the emergency breaker switch to kill the engine if it still running.
Indeed the alternator would keep providing electrical power to all the systems, including
the engine.
