This is a stupid question, but I got an 07 F8 this year. It has a 12v outlet on the dash. However there is no power going to the outlet that I could find up to about 3500 rpm's. Does the power develop at a higher rpm or is there something I need to look for that is bad??? The sled does not have elctric start (FYI) Thanks in advance and I appreciate all of your guys input.
