I had left my key in the on position for several hours and drained the battery down to the point that everything was dead, no dome light nothing.
I had jumper cables but the only other 12 volt battery on the property was in my home computer APC Battery Backup. I was able to remove one of the batteries from the computer backup and grip the little battery posts with the jumper cable claws. I had to let it sit for about 10 minutes, but when I turned the key, my Navigator started right up.
Sometimes you just have to work with what you have.
