The code you posted looks okay. Is there somewhere else in the program that might be continually turning off your winch motors, like in Periodic Tasks? Is the case input connected directly to a joystick button, or is there some other processing before it reaches the case?

Is your motor wiring correct, with both motors turning in a direction that doesn't make them fight each other? Install only one winch motor circuit breaker and try running it, then remove that breaker and install one on the other winch motor. Do the motors run as expected one at a time?
