How to fix inoperable external power receptacle in Cirrus Aircrafts?
- BBrian RussellAug 27, 2025
If the external power receptacle is inoperable on your Cirrus Aircrafts, ensure that the BAT 1 switch is in the ON position. If it is already ON, inspect and repair any faulty ground wire/connection at the receptacle or firewall ground bus bar. If the issue persists, the ground power relay may be faulty, and the MCU should be replaced.
