Bat bone, KK2, tail servo issue

Got a bat bone and KK2 board. Motors power up just fin.
Tail servo does not move connected to output #4 on KK2. Yaw controls shows working in "receiver test" on KK2 board. Connecting servo directly to receiver works fine. Any ideas?
Thanks,
JD

You have the ground wire (Brown or Black) of the servo connected to the KK2 so that it is closest to the right edge of the board, right? Pictures would help too.

Edit: Also, do you have power wires from the ESC connected on Motor 2 or 3 as well? If memory serves correct, Motor 1 powers the board, but motor 2 provides power to any load (servos) for motors 3 through 8.
