As a fellow WT-150 operator first thing I'd check is the connections to the motor. Check the screw terminals under the cover on the terminal block (black plastic box) on the motor. Next, check the terminals on the amplifier modules in the cabinet. It should be the 2nd and 3rd amplifier left to right. With the power off, break them loose and re-tighten them. Power up and see if that cures it.
