Is there a way to connect ground power on the PC12? I know there is a switch for it on the overhead panel but I haven't found anything that actually connects the GPU. Not getting my hopes up that Carenado included this but I figure I would ask.

Not directly; however, I've discovered a gauge created by a user http://www.douglassdawson.ca/ "batt charger" that seems to work. I've attached the guage to my B200 and C208. I don't know how to do the gauge properly like it pops up and I can see it "on" but I've added it and press the key that would normally pop a gauge up and it works...

Hi , does it actually charging ? I have try that ,but still were  loosing power while programing GPS. 

Thanks Petr
