Topaz conveyor not working

The conveyor on our Topaz runs for about a second then stops. Turning on conveyor manually does the same thing. While conveyor is turned on manually, disconnecting and reconnecting 208AC at connection board starts the conveyor for a second then it stops. Swapped out motor, cap, and connection board with working machine, but problem remains. Help?

Edit: The problem turned out to be due to a damaged wire at the speed control pots at the front of the machine. A mouse had gotten into the machine and chewed through the cable.
