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 directly “hot-wired” to the battery and
can be used to charge the battery without the pilot having to connect additional
leads directly to the 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.
The Instrument Switch (INST) 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 296 GPS contains six AA batteries. The Garmin 396496 GPS 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 batteries should be replaced at each annual inspection.
The battery furnished with the Garmin GPS battery should be checked at each
annual condition inspection and replaced in accordance with the GPS supplier’s
instructions.
