Troubles with Talon SRX in Follower mode

[jfitz0807]

The self test shows that the talons are in follower mode. When I run the self test with the motors running, the lead talons show a non-zero current value, but the following talons show 0 current.

Here is the code we are using to set the talon:

driveSubsystemMotorControllerBackLeft->SetControlMode(CANSpeedController::kFollower);
driveSubsystemMotorControllerBackLeft->Set(3);

driveSubsystemMotorControllerBackLeft is Talon 4.

If I understand correctly, this should set Talon 4 to follow Talon 3. We have similar code for Talon 2 to follow Talon 1.

Am I doing something wrong?
