I'm sorry to report that I had several wires on my 700Li short and cause the rear tail-lights to go out. The wires are the yellow and green coming our of the controller at the point where they are connected with metal connectors to go outward to the tailights.
They melted the the plastic bag and thank goodness no other damaged was caused. All other electrical system still work. Needless to say, this has stopped any night-time driving.
I called X-treme and got a ticket number and since it's only been two days it's too early to report how this was resolved. Has anyone else had this problem?
