Electrical System - Piper Dakota PA-28-236 Pilot Operating Handbook

SECTION 7
DESCRIPTION & OPERATION
7.17 ELECTRICAL.SYSTEM
The electrical system includes a 14-volt, 60 amp alternator, a voltage
regulator, an overvoltage relay, and a master switch relay (Figure 7-11 ).
The 12-volt battery is mounted in a thermoplastic box immediately aft of the
baggage compartment. 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
(Figure 7-15), and the circuit breakers are located on the lower right
instrument panel (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 starter, electric fuel pump, stall
warning indicator, 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 the applicable system gauge should be checked and
monitored to determine when or if any necessary action is required.
Optional electrical accessories includes navigation, ground recognition,
anti-collision, landing, instrument and cabin dome lighting.
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.
An optional wing tip I recognition light system consists of 2 lights (one
in each wing tip) and is operated by a split landing light/ recognition light
rocker type switch mounted on the switch panel.
Anti-collision lights should not be operating
when flying through cloud, fog or haze,
since the reflected light can produce spatial
disorientation. Strobe lights should not be used
in close proximity to the ground such as during
taxiing, takeoff or landing.
