Sorry if this is the wrong thread but I'm trying to attach parts from the kerbals inventory, I'm using an engineer. as a test I put a pod on the pad and tried to attach solar panels and batteries using H as the pop up says... It doesn't pace, it just turns red I put up a skylab but silly me figured a craft as large as that would have a lot of batteries installed in it and a transmitter --- out of the box. would rather refurb than have to launch another one (like NASA would do!) What am I doing wrong?
