Indicator Lights and Alarms
The instrument panel is equipped with several indicator lights:
Charging indicator light. This light should illuminate after switching the
Master switch on and indicates that the installed battery is not charged. The
light should fade after starting the engine, when the charging voltage
reaches approximately 12V (the battery starts to be charged by the
alternator) and should go out completely when approximately 13V is
reached. If the charging indicator light illuminates in flight, it may indicate a
failure of the alternator or that the battery is discharged and alternator is
unable to power installed instruments and charge the battery as well.

If a stall warning is installed in your airplane, the function of that system
may be tested prior to flight. Switch on the Master switch and gently lift the
stall warning flap on the wing leading edge. You should hear a sound signal
from the cockpit.
Also some instruments may have their own warning lights, e.g. the fuel qty
indicator may have a light to indicate minimum fuel qty.
