Joe,

Our team is having a huge glitch. As soon as we enable the robot, the Victors throttle full forward. Also, Relay 1 and 2 go to forward as well. All four feedback lights on the OI are green (PWM1, PWM2, Relay1, Relay2). These 4 outputs do not respond to the OI, but the other relays still work.

The problem used to be intermittent, but it is now a full-time pain in the neck. I have check all of the fuses, wiring, and switches on both the OI and RC. I disconnected all motors and no change. I disconnected all PWM cables as well and still no change. I have used the tether, and no change. I have tried both batteries, fully-charged, and no change.

The only thing that seems to work is when I unplug the joystick for Port 1, the feedback LED for PWM1 turns off. The equivalent happens with Ports 2, 3, and 4.

The only thing I can think of is to re-download the user code in case running the robot at low voltage caused a problem(The motors caused the voltage to drop below 11 volts under heavy loads). So, if is not giving up any trade secrets, could you please e-mail me directly the user code?

I'll keep looking for a solution.

Thanks,
Jason
