ELECTRICAL SYSTEM
The standard 24 volts and 105 amps electrical system consists of the starting system, the
navigation lights, the wiper/washer system, and the strobe lights. The landing lights, the working
lights, and the air conditioner system are optional. The landing and working lights may be installed
in the field, since the wiring for them is included in the standard wire bundle. The electrical system
obtains power from two 24-volt batteries and one starter/generator. An external power receptacle is
standard equipment and may be used for connecting a 24-volt ground power unit to the aircraft for
engine starting or maintenance. The ground start system utilizes the master relay so that starting is
accomplished by engaging the starter switch.
