You're driving 2 CIM motors with each Victor:

That's a non-no.

Good catch! Very big no no. You either need to get rid of a CIM motor on each side, or add additional speed controllers. If you decide to keep both CIM motors, you can either use a Y-PWM cable, which splits the signal (I believe these are provided in the KOP), or you can use additional PWM cables and reconfigure your Drive code to use 4-motors instead of 2-motors.

If you use the Y-PWM cable, there is no need to change your code.

Also, on topic, what documentation said to use the 5V output? Can you post a link?

Thanks! The first wiring diagram we saw told us to use the five volt.

Can you post the wiring diagram you're using? This year's FIRST wiring diagram looks ok to me. http://www.usfirst.org/sites/default...icalLayout.pdf
