The amber SOURCE OFF light supplies indication that an AC transfer bus is
not energized by the selected source. The left SOURCE OFF light is related
to these sources:
• IDG 1 (GEN 1 switch)
• APU (left APU GEN switch)
• External power (ground power switch).
The right SOURCE OFF light is related to these sources:
• IDG 2 (GEN 2 switch)
• APU (right APU GEN switch)
• External power (ground power switch).
The SOURCE OFF light does not indicate that the AC transfer bus is
de-energized. In flight, the left SOURCE OFF light comes on when GCB 1
trips. However, the bus transfer function lets IDG 2 power AC transfer bus 1.
These are the examples:
• IDG1 fails
• The bus transfer function closes the BTBs
• Both AC transfer buses get power from IDG2.
There is one light for each transfer bus.
