We have a couple new controllers on order.

We actually did quite a bit of testing and troubleshooting while we were at CalGames. In fact, we ended up calling in a replacement in the elimination matches because of the difficulties and time it would take to replace it. We definitely narrowed it down to the Victor. It is on a "Y" PWM cable with the second motor on that side of the drive. When we pulled the PWM from the bad Victor once we were back in the shop, the other Victor on that side ran normally. This shows that the code was correct and had not changed. All testing in the shop was with a fresh battery.

I'm fairly certain the Victor is toast. Just it's odd behavior alone is indicative of internal problems with the Victor.
