i) The connections on the engine side should be made according to the engine
installation manual and the electrical system schematics.
j) On the 912 the optional capacitor shown in the wiring diagram and the Rotax
installation manual may be fitted if desired, although it is rather bulky.
This has two uses: if you experience interference with your radio through its
power supply from the regulator, the capacitor will reduce this by smoothing
the supply a little, although the battery already does most of this and a radio
power interface does the same thing. The capacitor also provides a fail-safe
against accidental disconnection of the battery whilst the engine is running,
which would otherwise cause the regulator voltage to rise with possible
damage to instruments, radio etc.
Disconnection would occur either by blowing of the fuse to the battery or if the
wire to terminal C on the regulator were to become disconnected.
A suitable capacitor is available from Rotax/Skydrive. If only protection from
disconnection were required, a smaller capacitor could be used at your own
discretion.
k) Other optional items are shown on the wiring diagrams: they are an hour-
meter, a master-switch warning buzzer, and a start-button warning light.
l) If a master warning buzzer is required on a Jabiru installation the wiring must
be altered to disconnect the regulator from the battery in a similar manner to
the 912 installation, using a double-pole switch. The buzzer may then be
connected between the unused connection on the regulator and earth.
m) Additional systems such as GPS, radio etc. should be individually protected by
fuses of the appropriate size.
