Abstract: An apparatus comprised of a processor, a display, and a current measuring device is provided. The current measuring device is adapted to measure the current in a first winding of a first stator of an alternating current motor. The processor causes a first message to be placed on the display if the current in the first winding of the first stator falls outside a first range of values. The first high value and the first low value can be stored in a memory device. The current measuring device may have two input ports, for measuring current in first and second windings of the first stator of the alternating current motor. The processor may cause a second message to be placed on the display if the current in the second winding of the first stator falls within a second range of values. A first relay device for selecting between a first start signal and a first run signal. During a start time period, the processor causes the first start signal to be transmitted to the first winding of the first stator.
