12.2.4 Voltage Regulator
The voltage regulator is a sealed unit. Service is limited to inspection of terminals for security and
replacement of the unit.
12.2.5 Strobe System (Option)
A strobe light may be installed in the tip of the tail fin or on the wingtips.
The power source for the strobe light is located in the engine bay.
For best noise suppression, ferrite beads must be fitted to the power & earth wires leading to the
power supply. Shielded wires must be used for the connection to the lights themselves and the
shielding must be electrically continuous between the light and the control box. Ensure the box itself
is connected to the aircraft’s earth with minimum impedance. Refer to Figure 195 and Figure 196
WARNING
The strobe system is a high-voltage device. Do Not remove or touch tube assembly while in
operation. Wait at least 5 minutes after turning off power before commencing any activity near
the strobe light.
12.2.6 AUXILIARY Power Socket
The Jabiru is fitted with an auxiliary power socket that accepts a 12V cigarette lighter plug. The
circuit breaker for this plug is rated a 5 Amps.
