ELE C TRI CAL SYSTEM.
Electrical energy is supplied by a 14-volt, direct -current system
powered by an engine-driven alternator (see figure 2-4).
A
12-volt
storage battery is located on the right, forward side of the firewall just
inside the cowl access door. The master switch controls all electrical
circuits except the engine ignition system, optional clock and optional
flight hour recorder (operative only when engine is operating).
AMMETER.
The ammeter indicates the flow of current, in amperes, from the
alternator to the battery or from the battery to the aircraft electrical
system. When the engine is operating and i.he master switch is "ON, "
the ammeter indicates the charging rate applied to the battery. In the
event the alternator is not functioning or the electrical load exceeds the
output of the alternator, the ammeter indicates the discharge rate of the
battery.
FUSES AND CIRCUIT BREAKERS.
Fuses on the right side of the instrument panel protect the majority
of electrical circuits in the airplane . Labeling above each fuse retainer
indicates the circuits protected by the fuses. Fuse capacity is shown on
each fuse retainer cap. Fuses are removed by pressing the fuse retainers
inward and rotating them counterclockwise until they disengage. The
faulty fuse may then be lifted out and replaced. Spare fuses are held in a
clip on the inside of the map compartment door.
NOTE
A
special "SLO-BLO" fuse protects the wing flaps circuit.
If this fuse is replaced, care should be taken to assure
that the replacement fuse is of the proper type and capa­
city. A "SLO-BLO" fuse is identified by an integrally
mounted spring encircling the fuse element.
Two additional fuses are provided in the airplane. A fuse located
adjacent to the battery protects the optional clock and flight hour recorder
circuits.
An in-line fuse located in the wire bundle just left of center be­
hind the instrument panel protects the alternator field circuit.
A
"push-to-reset" circuit breaker (labeled "GEN") on the instrument
panel protects the alternator circuit. The cigar lighter is protected by a
