SECTION X
ELECTRICAL SYSTEM
GENERAL
The electrical system of the is a 12 volt, direct current, single wire, negative ground
system. All electrical equipment is grounded to the metal structure of the airplane,
therefore the structure takes the place of the second wire. A 12 volt battery is incorporated
in the system to furnish power for starting and as a reserve power source in case of
alternator failure. The battery and alternator are both connected to the bus bar; from
which all the electrical equipment is powered, with the exception of the starter which
receives its power from the load side of the battery. The master switch, located on the
switch panel below the instruments, controls the battery relay. The master switch must be
on before any electrical equipment will operate. The can be equipped with the standard
navigation lights, strobes, and dual landing lights located in the wing leading edge.
Alternator output is 60 AMP when aircraft is equipped for IFR.
TROUBLESHOOTING
Troubles peculiar to the electrical system are listed in a Table at the end of this section
along with their probable causes and suggested remedies.
After the trouble has been corrected, check the entire electrical system for security and
operation of its components.
ELECTRICAL POWER SUPPLY
The electrical power is supplied by one 12 volt battery and one 12 volt direct current
alternator. A voltage regulator is incorporated to prevent overloading of the battery and
electrical circuits.
For electric wire schematics, contact the manufacturer.
