Fuel quantity and fuel pressure gauges are mounted in a gauge cluster located on the left side of the
instrument panel to the right of the control wheel (refer to Figure 7-15).
An optional engine priming system is available to facilitate starting. The primer pump is located to the
immediate left of the throttle quadrant (refer to Figure 7-5).
7.15 ELECTRICAL SYSTEM
The electrical system includes a 14-volt, 60 amp alternator, a 12-volt battery, a voltage regulator. an over-
voltage relay and a master switch relay (Figure 7-11). The battery is mounted in a thermoplastic box
immediately aft of the main spar on the right side of the fuselage below the rear passenger seat. The regulator
and overvoltage relay are located on the forward left side of the fuselage behind the instrument panel.
Electrical switches are located on the right center instrument panel (refer to Figure 7-15) and the circuit
breakers are located on the lower right instrument panel (refer to Figure 7-13). A rheostat switch on the left
side of the switch panel controls the navigational lights and the radio lights. The similar switch on the right
side controls and dims the panel lights.
Standard electrical accessories include a starter, electric fuel pump, stall warning indicator, cigar lighter,
fuel gauge, ammeter, and annunciator panel.
The annunciator panel includes alternator and low oil pressure indicator lights. When the optional gyro
system is installed, the annunciator panel also includes a low vacuum indicator light. The annunciator panel
lights are provided only as a warning to the pilot that a system may not be operating properly, and that he
should check and monitor the applicable system gauge to determine when or if any necessary action is
required.
Optional electrical accessories include navigation lights, anti-collision light, landing light, instrument
lighting. and cabin dome light. Circuits will handle the addition of communications and navigational equip-
ment.
An optional light, mounted in the overhead panel, provides instrument and cockpit lighting for night
flying. The light is controlled by a rheostat switch located adjacent to the light. A map light window in the lens
is actuated by an adjacent switch.
WARNING
Anti-collision lights should not be operating when flying through
cloud, fog or haze, since the reflected light can produce spatial dis-
orientation. Strobe lights should not be used in close proximity to
the ground such as during taxiing, takeoff or landing.
NOTE
On airplanes with interlocked BAT and ALT switches, the ALT
switch is mechanically interlocked with the BAT switch. When ALT
switch is turned ON, the BAT switch will also be turned ON. On
airplanes with separate BAT and ALT switch operation, the
switches may be positioned independently as desired.
