Troubles with Talon SRX in Follower mode

[jfitz0807]

I have 4 Talon SRXs controlling 4 CIMs on the KoP chassis drive train. CAN ID 1 is front left, 2 is back left, 3 is front right and 4 is back right. I set both 2 and 4 to follow 1 and 3, respectively. In this configuration, it looks like 2 and 4 have stopped driving. The red and green lights no longer light up when driving.

Also, when running the Talon self test from the roboRIO configuration window with the robot enabled, Talons 2 and 4 do not report any current. Similarly, GetCurrent returns values of zero.

Is this expected behavior for a Talon in follower mode? If not, any suggestions?
