External Power & Maintenance

[pbrad74]

I have installed, uninstalled and then reinstalled. Every time I load into the 600F Premium, I have to service both engines, hydraulics and the APU even though I have the option turned off. If I don't, everything is at 0%. I turn all 3 batteries on but can't get the External Power button to illuminate even after servicing the APU and attaching the GPU, although that button doesn't stay lit when I click it. There are other problems too like sunshades and the instrument panel is illuminated every time I load in. I'm at a loss and don't know what to do.
