AIRPLANE AND SYSTEM DESCRIPTION

AIRPLANE FLIGHT MANUAL ORIGINAL ISSUE -- 04-02-2008
Push--pull or rocker switch--circuit breakers automatically break the electrical current flow if the
system or unit receives current overload to prevent damage to electrical wiring. Figure 7--9 illus-
trates a typical main circuit breaker panel with its push--pull circuit breakers. Rocker switch--cir-
cuit breakers are at the bottom and left of the pilot’s flight panel.
The alternator’s push--pull circuit breaker, on the main breaker panel, furnish an emergency
overload break between the alternators and the power bus. Since the alternator is incapable of
output in excess of circuit breaker capacity, a tripped breaker normally indicates a fault within the
alternator.
NOTE:
NEVER fly the aircraft with a severely discharged battery, even if you do not plan
to use it. Selection of a severely discharged battery in flight can cause a current
”in--rush” from the alternator, and may damage on--board systems.
The alternator field has a push--pull circuit breaker to furnish an emergency break in the alterna-
tor field excitation circuit in the event of alternator or voltage regulator malfunction. If regulator
output voltage exceeds limits, the warning light illuminates steadily and the alternator field circuit
breaker trips.
Resetting the alternator field circuit breaker should reset the alternator. If the circuit breaker will
not reset, continue flight with minimum electrical load. The flight will be continued using only bat-
tery power, caution is advised to not drain both batteries if electrical power will be required before
you are able to land. Land when practical to correct the malfunction.
NOTE:
The circuit breakers installed in the panel may vary depending on installed equip-
ment.
ACCESSORIES
Standard electrical accessories include the starter, the electric fuel pump, and the stall warning
horn. Electrical accessories include the navigation lights, anti--collision strobe lights, instrument
panel lighting, and cabin courtesy lights. Make sure the lighting and Emergency Bus switch, as
well as the STBY GYRO circuit breaker are de--energized when leaving the aircraft. Leaving
these systems energized for an extended period of time could cause depletion of the battery.
Two lights, mounted in the overhead panel, provide instrument and cockpit lighting for night fly-
ing. A wing tip position light system consists of 2 lights on each wingtip and is operated by a rock-
er type switch mounted in the overhead switch panel. Landing and taxi lights are mounted on the
wing leading edges on both wings.
Wing tip and tail mounted Strobe lights are controlled by a rocker type switch mounted in the
overhead switch panel.
The M20TN electrical system is divided into two power buses. A simplified schematic of the elec-
trical system is shown in the diagram which follows.
ANNUNCIATOR PANEL
The landing gear, low fuel, speed brakes, speed brake, alternate air, prop de--ice and pitot heat
lights are grouped in the upper annunciator panel. The alternator fail, start power, emergency
buss and boost pump are grouped in the lower annunciator panel. A test and dim switch are also
found in the panel; each of the lights and switches are discussed elsewhere in this Section.
LIGHTING SYSTEM
INSTRUMENT & PLACARD LIGHTS
All placards are floodlighted by lights from the glareshield. There are two rheostat knobs on the
right hand radio panel. The left control regulates intensity of the placard lighting. The right control
provides avionics and instrument lighting. Rotating the knobs clockwise turns ON and increases
light intensity.
