Rotated cars last night so could drive GN to work today. All was ok. This morning GN no power, not even that click click sound. Always have good Optima batteries, but things happen, so hooked up charger. That's odd, overhead & interior lights are on and doors are closed. While charger still on I disconnect positive battery lead, & sure enough no interior lights, re-connect positive & lights come back on. I fiddled with key, tried moving the steering column collar (that does the trick in my older car), jiggled the shifter...all makes no difference. Car has been running fine, no problems last night, & everything under hood looks normal. So power is coming into the cabin but key is off, thus drained the battery. Why? One of those GN poltergeist? Please tell me this is cheap, fast and easy to fix (oh, & how do I fix it). Thanks, do appreciate suggestions.
