7.11. ELECTRICAL SYSTEM
7.11.1. Power Supply
A 12 V battery is connected to the master bus
via the master circuit breaker (50 Amps). The
40 amp. generator is attached to the engine
near the propeller hub, recharges the battery
via the generator circuit breaker (50 Amps).
Both circuit breakers can be triggered
manually. The generator warning light is
activated by the voltage regulator monitoring
circuit and illuminates when the generator is
not charging the battery.
7.11.2. Ignition System
The engine is provided with two independent
ignition systems. The two magnetos are
independent from the power supply system,
and are in operation as soon as the propeller
RPM is greater than 100. This ensures safe
engine operation even in case of an electrical
power failure.
WARNING
If the ignition key is turned to L, R or BOTH, the respective magneto is "hot". If the
propeller is moved during this time the engine may fire and cause serious or fatal injury to
personnel.
