7.14 Electrical System
An electrical schematic for the aircraft is shown in the diagram on the following page.
The Electrical circuits comprise:
•
an instrumentation circuit. The 12V DC supply is protected by a 20 amp fuse at the battery and a 10 amp
circuit breaker mounted on the dash. The master switch on the dash, when in the off position, disables
the DC power socket, flight instrument and the electric start push button;
•
an engine management circuit; and
•
an ignition circuit.
It should be noted that the ignition circuit is a fail-safe system whereby the engine will run in the event of the
ignition circuit becoming disconnected. Switching the coil to ground stops the engine.
When stopping the engine both switches on the side of the seat should be switched off. The master switch
on the dash should then be turned to the off position to remove supply to the accessories.
If necessary the motor can be stopped using the chokes as detailed in section 3.3.10 of this AOI.
Refer to the Rotax manual for more details for the engine electrical system.
