I did that with my contour... I had a remote starter, and when the car is in the ON position, i was able to press the button, and then take the key out, and leave the car on... Well I turned the car to acc, then back to On, then did it so the engine was off, but the radio stayed on so I can have my music blasting as i walk to work... Bout a few hours later "Hey.. Dont you own a purple contour?? Its almost dead..."
I forgot my lights were on... and since the chimes didn't activate, I didnt check if my lights were on or off on a bright sunny day... I later started my car off MonsterCable speaker wire
Supringly, it gave my car that boost of power to kick the starter over
