Yes sir, that burned copper trace is the 12 volt supply to center leg of the limiter. Compare that frail copper ribbon to a wire. It never was meant to carry a substantial amount of current. It did burn open in a fault condition just as a fuse would. Where the root fault was? We don't know. What is the best method of repair? Someone attempted over repair with that length of white wire. Nearly anything bridged across the gap with a bit of solder would have worked.
