Just noticed this on the K/G during a routine service/tune. Traced it back to the stoplight sw- both terminals were live. Funny, it's only 2 years old & they have only gone wrong in the past for me by going dead. I jacked up the front to get at it & it fixed itself!! There was a sliver of metal from manufacturing peeling off the central boss of the sw & touching the terminal to the lights when the car was flat! Geez, 30 years of fiddling & I still get surprised!!
