Connection to the wiring is via crimp connections in rubber connector housings and, in the case of the power
wiring loom, via spade terminals to a multiway fuseholder at the front of the aircraft.
All models are fitted with a regulator, which charges the battery where fitted. Electric start models have a
solenoid for transmitting current to the starter motor. A safety cutout switch may be fitted to prevent starter
operation with the hand throttle open.
The Alternator
Rotax 912/912S
: the alternator gives a nominal maximum current of 18 amps AC or voltages up to about 75
volts RMS with very low current. The nominal power rating is 250 Watts DC.
Power Wiring
The power wiring loom consists of insulated conductors inside a woven nylon sheath with a rubber connector
at the rear end and spade terminals at the front. A 2-core cable and switch for engine ignition control is also
included for each ignition circuit.
Note that airworthiness requirements specify that all electrical equipment attached to the wiring system must
be protected by overload protection devices and that no protective device may protect more than one circuit
essential to flight safety. To this end a multiway fuseholder is provided at the front of the aircraft for the
attachment of electrical equipment.
Operators wishing to fit equipment themselves must contact their dealer with a modification scheme, the
dealer will obtain modification authorisation from the factory.
Sensor Wiring
The sensor wiring system comprises a multicore cable intended for transmission of signals not involving
significant power levels. No items requiring significant power with an alternating component should have
their supply lines attached to this cable as electrical interference with sensor signals may occur.
Unauthorised modifications, including the fitting of optional electrical
equipment, must not be carried out under any circumstances without
official modification authorisation issued by the factory.
CAUTION
When the aircraft is stored for an extended period of
time, remove the battery and charge it fully. Then
store it in a warm dry place. Never leave the battery
discharged.
