If flight conditions permit, consider shedding the following to
preserve Battery 1:
(1)Air Conditioning
(2)Landing Light
(3)Yaw Servo
(4)Convenience Power (aux items plugged into armrest jack)
(5)EVS Camera (if installed)
c. Continue Flight, avoiding IMC or night flight as able (reduced power
redundancy).
Dependent on Battery 1 state (indicated by M1 voltage), landing
light may be weak or inoperative for landing.
Alternator 1 output is low, indicative of alternator failure and will
typically be associated with low M1 voltage, Battery 1 discharge
