Re: Mistakes

The black wire on the PWM cable goes closest to the fan on the victor, plugging it in backwards ONCE will destroy the unit.... It took our team 2 years of random dead victors before we read the manual and obtained this key bit of information.
It really didn't help that our troubleshooting method before we obtained the manual was to plug the wire in the other way to make sure it wasn't backwards.

Another problem we had was one when the serial cable plugged into the radio on the robot came loose. The end plugged into robot controller was still secure. Somehow, the positive lead from the battery was also loose (after the main breaker). Someone went to turn on the robot and we had smoke everywhere. The battery grounded through the RC via the serial cable ground casing, causing the wire to heat up and burn the insulation.
Fortunately, no permanent damage other than the serial cable.
