APU Generator (APU GEN) Control Switches

Pushing the APU generator control switch illuminates the AVAIL light, connecting the related APU generator to provide power to the aircraft's AC electrical system, except it will cause the main deck cargo handling bus to lose power if powered by APU generator 2. Pushing the switch again illuminates the ON light, disconnecting the APU generator from the electrical system. The AVAIL light illuminates when the APU generator is providing acceptable power and powers the main deck cargo handling bus when APU generator 2 is in use. The ON light illuminates when the APU generator is connected to the electrical system.
