ELECTRICAL 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 clock and the ignition system.
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 the 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 instrument panel protect most of the electrical circuits
in your airplane. (The clock fuse is located adjacent to the battery.) The
circuits controlled by each fuse are indicated above each fuse retainer.
Fuse capacity is indicated 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.

the alternator circuit. The cigar lighter is protected by a manually re-
set type circuit breaker mounted directly on the back of the lighter behind
the instrument panel.
LANDING LIGHTS (OPT).
A three-position, push-pull type switch controls the optional landing
lights mounted in the leading edge of the left wing. To turn one lamp on
for taxiing, pull the switch out to the first stop. To turn both lamps on
for landing, pull the switch out to the second stop.
FLASHING BEACON (OPT).
The flashing beacon should not be used when flying through clouds or
overcast; the flashing light reflected from water droplets or particles in
