3.7.4.2 Alternator B Failure –
Alternator B failure is evident by the steady illumination of the Lane B
warning light, and a drop in the main bus voltage to nominal battery
voltage (+/- 12.5 V).
1. Lane B ................................... CYCLE SWITCH
(OFF 1 SECOND, BACK ON)
2. Lane B ................................... VERIFY WARNING LIGHT OFF
If Lane B warning light is still on – assume alternator failure.
3. ECU Backup ........................... ON
4. EFIS Backup ........................... ON
5. Non-essential Equipment...... OFF
(c)
Lights, autopilot, secondary EFIS, etc.
6. Radio Communication .......... MINIMAL
7. Land ...................................... AS SOON AS PRACTICABLE
c. No battery charging will occur in this scenario, and the main
battery must be conserved if there is to be a subsequent
alternator B failure.
