Electrical Systems

12.1 Electrical Power Supply System (all J-Series)

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.
12.1.1 Wiring Diagrams

The wiring diagram for a standard aircraft is shown in Figure 195 and Figure 196.

The wiring diagram for night-VFR lighting is shown in Figure 197 and Figure 198.
