96.1.5 Primary and Secondary
Electrical Power Analysis
The helicopter is equipped with a 28 volt direct
current electrical system. Power for this system
is supplied by a 42 ampere-hour, lead acid
battery and a 28 volt, 300 amp starter/generator.
Major components of the direct current power
system consist of the battery, starter/generator,
DC control unit, relays, and circuit breakers.
Circuits in the electrical system are single
conductor circuits with the negative leads of the
battery and starter/generator ground to the
helicopter structure.
A secondary source of power, used to operate
the equipment that requires alternating current is
supplied by a 250 Volt-amp, single phase, solid
state inverter. Two such inverters are included in
the system, but only one operates at any given
time.
Operational checks should be performed using
external power whenever possible. After repair
or replacement of equipment or a system,
operational checks should be conducted to
ensure that the helicopter electrical systems are
functioning properly. Utilize system wiring
diagrams (Chapter 98), and equipment location
diagrams (Drawing D212-725-8, D212-725-8-G2,
Appendix A), in accomplishing functional tests of
electrical circuits and components. This manual
does not provide functional or operational testing
for equipment requiring bench testing.
