IGNITION SYSTEM
The engine ignition system is independent of the aircraft electrical system
except that the aircraft battery is needed for starting.
The system comprises the following components:
•
Magnetos
•
Spark Plugs
•
Ignition Switch
•
Start Button
•
Spark Booster
During normal operation, the engine should be run with the magneto switch
in the BOTH position. Operation in the left or right position will cause a loss of
power.
CAUTION
If the STARTER caption remains illuminated after the release of the starter
button, stop the engine and reload the aircraft.
ELECTRICAL SYSTEM
The aircraft uses a DC electrical system powered by either a 24 volt battery or
an engine driven generator of 28 volt output.
The power is distributed through 4 busbars and most systems are protected by
circuit breakers. The circuit breakers are arranged in busbar groups in the
cockpit.
Battery
A 24 volt, 13.6 amp per hour battery is located behind the cockpit rear
bulkhead on the right side of the fuselage.
A battery switch connects the battery to the Main busbar through a battery
relay which also incorporates a ground supply relay that connects an
external power supply to the Main busbar
The battery should provide power for 30 minutes after a generator failure
provided that non-essential services are switched off. A LO VOLT caption
warns of failure.
