Further to that, it should be noted that you should never try to start a Cirrus using a Ground Power Unit with a flat battery. During annual, the service centre ran the battery down whilst chasing an issue with the EHSI and an inexperienced tech decided to fire my bird up by using ground power. Net result: melted starter, melted battery, destroyed solenoids in the MCU.
Fortunately, I didn't pay for the repairs, got a new battery and better starter to boot
What a ridiculous design. It wouldn't be difficult to build in a system to prevent that happening.
Didn't Cirrus consider that almost everybody would naturally think you could start from ground power when the battery is not up to it.
