SECTION 14 – ELECTRICAL SYSTEMS
16.1 ELECTRICAL POWER SUPPLY SYSTEM
Electrical energy for the aircraft is supplied by a 12 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
electrical power system failure.
An engine-driven Alternator is the normal source of power during flight and maintains a battery
charge controlled by a voltage regulator. Depending on the aircraft model a 120 Watt or 200 Watt
alternator may be fitted.
The following paragraphs provide brief descriptions of the elements of the electrical system. They
should be read in conjunction with the Wiring Diagrams below.
Due to space constraints not all different variations are shown herein. When ordering spare parts
provide as must detail as possible
– part description, aircraft model, serial number etc to Jabiru to
ensure accurate part identification.
16.1.1 WIRING DIAGRAMS
The wiring diagram for a standard aircraft is shown in Figure 181 and Figure 182.
The wiring diagram for night-VFR lighting is shown in Figure 183 and Figure 184.
