ALTERNATOR FAILURE
ALTERNATOR A FAILURE (ALTERNATOR B OPERATIVE)
When Alternator A fails (with alternator B still operative) the EMS/ECU is
automatically switched over to Alternator B. Note that in this event Alternator B
output is not (or only partially) available to the aircraft systems / to charge the
main battery.
Procedure as in paragraph 3.7.4.
Alternator A failure is evidenced by the steady illumination of the Lane A (red)
warning light. The main bus / system voltage (indication on EFIS) could show a
reduced reading.
WARNING
The engine will continue to run after an Alternator A failure (with
Alternator B still operative), as the EMS /ECU is then powered by
Alternator B. However, since no charging of the battery occurs in this
circumstance all non-critical electrical equipment should be switched
off to conserve battery charge (as the battery would be needed to
supply power to the EMS/ECU/fuel pump(s) if Alternator B
subsequently fails).
