Caution - Burned out CIM blows Victor

[sanddrag]

Had a bit of an interesting happening with some Victors the other night. We discovered the hard way (3x over) that a burned out CIM motors can easily blow the transistors on the Victor, before the breaker to the input will ever trip. I suspect that when the CIM motors run for too long, they overheat, causing the insulation on the windings to degrade, thereby causing an internal short. When we disassembled the motor, it was all black inside. So, be careful with how long you run your robot for at a time during practice, and check the temp of the motors often, or you may find yourself replacing a Victor.
