Electrical Bus
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
t r i g g e r e d m a n u a l l y. T h e
generator warning light is
activated by the voltage
regulator monitoring circuit and
illuminates when the generator
is not charging the battery.
7.11.1 POWER SUPPLY
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.
7.11.2 IGNITION SYSTEM
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.
