Question 4

ELECTRICAL SYTEM

Answer 4

ELECTRICAL SYTEM

• 24V Battery (Left Stub wing)
• 28v engine driven alternator - 50 amps
• Voltmeter - L ALT / R ALT / BATT, VOLTS
• OVERVOLTAGE RELAY - Monitors system voltage. If voltage exceeds a predetermined max, the relay will open and both alternators will be disabled.
• EMERGENCY POWER SWITCH - Provided in the alternator system and located on the aft side of the CB console. Used when the alternators will not self excite. Placing the switch in the ON position provides excitation from the battery even thought battery is considered to have failed.
