Try powering up the robot with no Victor installed, and measuring the voltage on the wires that you intend to connect to the V+ and V- terminals. Also test the motor that you intend to connect to the M+ and M- terminals.

The motors all seemed to have the same resistance between them, so there isn't a short in the motors. We tested each motor individually on an older speed controller. They both worked going through a 20 AMP breaker (just in case there was a problem with too much current). We then wired it back up the same we had it (through the 40 AMPs) and its all working fine now. Although we're still not positive what the problem was.
Thanks for everyones help.
