My 2000 Ovation has the standby alternator installed, and I'm glad to have it in my all-electric plane. If the main 100 ampere alternator fails the backup 20 amp alternator can be switched on. If necesary the pilot may pull the battery circuit breaker and then the 20A alternator feeds only items on the "Emergency Buss" which include, in my plane: ESI2000 standby AI with airspeed and altitude Nav/com #1. GTX750 audio panel transponder & encoder TKS and pitot heat engine instrument cluster & glareshield lights but that's all. Originally the KCS-55 was also part of this emergency buss, says the POH supplement. The G500, GTX650, autopilot, shadin all go dark. (Even the XM music goes away, a real hardship) The idea is to save your battery charge (both of them) until approach when you can then run gear, flaps, landing lights & etc. That makes sense. Q: As the G500 only uses about 3 amps could it and it's related AHRS, magnetic sensor be connected to the emergency bus?
