The pilot is the final and only responsible party for the safe operation of this aircraft.

ELECTRICAL SYSTEM AND INSTRUMENTS

This aircraft is equipped with a 12-volt, direct-current electrical system. The
source of electrical power is a battery that is attached on the engine side of the
firewall. An internal alternator located at the rear of the engine block will charge
the battery up to 13.5 VDC. Power is supplied to the electrical and avionics
circuits through a main bus bar located behind center instrument panel, this bus
bar is energized anytime the Main switch is ON. The ELT is independent from
the aircraft electrical system.
Two 12 VDC auxiliary power ports are installed in the lower right and left vertical
surface of each seat. The pilot side port is direct wired to the battery. It may be
used to enable a maintainer charge to the aircraft battery.
Do not attempt to start the engine with a dead battery by using the
12V DC port. The current load will exceed the wire capacity and a
fire may result. (Use the exhaust stack as the negative ground and
the positive bolt on the lower firewall below the cowling. A placard
indicates the location for ground personnel.)
The Instrument Switch activates all avionics equipment tied into the circuit. This
instrument switch should always be in the OFF position before the main switch is
turned on or before the main switch is turned off.
Both the GPS and the Emergency Locator Transmitter (ELT) contain internal
batteries, and therefore can be operated when Main switch is OFF. The
Garmin GPS696 contains a rechargeable lithium-ion battery pack. The ELT
contains eight D-cell batteries, as well as one small battery in the remote control
panel. All D-cell batteries should be checked and or replaced at each annual
inspection. The battery furnished with the Garmin GPS696 should be checked at
each annual condition inspection and replaced in accordance with the
manufacturer‟s instructions.

CIRCUIT BREAKERS AND FUSES

Circuit breakers and fuses are the best protection for electrical loads and
malfunctions. The most common form of protection for this aircraft is circuit
breakers (CB) and circuit breaker-switches (CBS). The CBs can manually be
