[SuperBK]

Watch the lights on the Victors to see what they do:
Green = Full Forward
Orange = Neutral / Brake
Red = Full Reverse
Flashing Orange = no PWM

If they flash when the motors stop, then they are not getting a PWM signal. Also, do you have a charged back up battery connected to the robot controller? It will provide power to the controller if the main battery dips for a short time.
