16-4. DESCRIPTION. Electrical energy for the air-
craft is supplied by a 14-volt, direct-current, single-
wire, negative ground electrical system. A 12-volt
battery supplies power for starting and furnishes a
reserve source of power in the event of alternator
failure. An engine-driven alternator is the normal
source of power during flight and maintains a battery
charge controlled by a voltage regulator. An external
power source receptacle is offered as optional equip-
ment to supplement the battery alternator system for
starting and ground operation.
