Re: drive train wearing out?

I haven't seen anyone throw this out yet, but you should also check your Victors. A few years ago, our robot had a weird issue of driving very weird in forward, but perfectly in reverse. When I took the fan off the victor, I saw that one of the transistors was blown, causing less power to go to the motor. With the stress of one motor driving the robot, the Victors take more abuse, which may cause them to fail.

To check this, just pop off the fan, get a small flash light, and look at each transistor and see if there are any pieces missing from them. Also check for melted plastic where the transistor enters the case. This is also a sign of something wrong.
