6.8 ELECTRICAL SYSTEM
The diagram attached in the Maintenance handbook shows the electrical system of the
autogyro.
With the Ignition switch OFF the engine is isolated. However, be aware that unless the
master switch is off other electrical items will work, and may draw current.
The starter should be used for short periods, 10secs maximum, as the nominal running
current draw from the starter motor may be up to 75amps. Overuse may result in internal
battery damage and early failure.
Use of optional items such as GPS units all draw a significant amount of current. The amount
will depend on individual circumstances.
