| 1. A cooling system diagnostic apparatus comprising:
a first sensor operable to sense a first cooling system parameter;
a second sensor operable to sense a motor operating parameter;
a controller in communication with said first and second sensors and operable to receive first sensor data from said first
sensor and second sensor data from said second sensor
a master computer having a memory storing a plurality of data sets containing normal operating parameters for a plurality
of systems; and
a computer in communication with said master computer to acquire one of said plurality of datasets from said master computer
and in communication with said controller to receive said first sensor data and said second sensor data, said computer comparing
said first sensor data and said second sensor data with said normal operating parameters to provide a diagnosis.
