16.1 Wiring General Points
A ready-made wiring loom is included with the engine installation package for
the Rotax 912, with standard instruments.
The instructions on wiring assume you
have either bought this, or are wiring it yourself in the same manner.
If you do not have a basic understanding of electrical systems it may be advisable to
buy an introductory text on electrics, especially if you are not using the ready-made
loom, or are adding extra equipment. This will serve you well throughout your flying
career, not just whilst wiring your Nynja!
When making connections, crimping is generally the quickest and best method.
Soldering may seem attractive, but introduces fatigue points and so is not generally
recommended.
Crimp tools: you get what you pay for. This is a good moment to spend as much as
you dare, your crimps will be better for it! Alternatively, you may be able to borrow or
hire a decent tool.
Keep all wiring neat, and ensure that no bare metal connections are visible which
may lead to short circuits. Heat shrink tubing is neater than insulation tape for this
job! It is available from Maplins, electrical and car accessory shops etc..
Secure the wiring with cable-ties, P-clips or similar, ensuring that it remains clear of
all moving and vibrating parts, and is protected from chafing against sharp edges.
Also ensure that the wiring cannot be accidentally damaged or disturbed by pilots‟
feet, baggage etc..
16.2 Low Current and Instrument Wiring
The low current wiring consists of that for the instruments, master switch and
magnetos, plus other ancillaries such as a radio.
a) Read the instructions which come with the engine and the instruments.
BMAA TILs 7 and 27 may be useful reading too.
b) The wiring loom should pass through the firewall alongside the central cabin
tubes.
On the 912 installation the port side is the clearest, The yellow solenoid
starter wire plus others sprouting from the main harness should be
positioned in front of the firewall.
c) The wires from the 912 magneto should also pass through the firewall in this
position, one set to the instrument panel for the tachometer, and one set to the
regulator.
See the engine instructions and wiring diagram for wire colours.
d) The ignition switch wires must also pass through the firewall, but keep them
away from the others. Amongst other (safety) reasons, this should reduce
electrical noise which may be audible in headsets and on the radio.
