Hi there! I have a 2011 Ford Edge 3.7 engine. The car has no electrical power, not even my key fob works to unlock and lock the car, when I turn the key switch to on, not a single sound or light turns on. The only electrical thing that works are the seats and charging ports inside the car. I got a new battery because I thought that would be it, I also got my alternator checked. What else would be the problem?
