15.1  Electrical system 

15.2  General 

This section contains service information necessary to maintain the aircraft electrical power 

supply system, battery, alternator power system, aircraft lighting system and electrical load analysis. 

15.3  Electrical power supply system 

15.4  Description 

Electrical energy for the aircraft is supplied by a 14-volt, direct-current, single-wire, negative 

ground electrical system. A 12-volt battery supplies power for starting and furnishes a reserve source 
of power in the event of alternator failure. An engine driven alternator is the normal source of power 
during flight and maintains a battery charge controlled by a voltage regulator. 

15.5  Master wiring system 

The aircraft is equipped with a master wiring system, featuring various terminal connectors to 

provide  easy  installation of additional electric equipment. The master wiring also provides a master 
power bus and an avionics power bus system. Refer to Section 18 for detailed wiring diagrams. 

15.6  Switch panel 

A  switch  panel  is  located  at  the  right  hand  side  of  the  instrument  panel.  All  switches  are 

located in this area, apart from the keyed and magneto switches which are located on the left side of 
the instrument panel. 

15.7  Keyed switch 

The  keyed  switch  is  located  below  the  magneto  switches.  The  keyed  switch  operates  the 

battery and alternator system. The switch, when operated, connects the battery to the engine wiring 
system, activating the power systems.
