In a transport refrigeration system which is susceptive to having its drive motors connected to a power source in reverse phase relationship to thereby operate the drive motors in reverse, provision is made to measure the current flow to the motors during operation in each direction and for comparing those current flows to determine which is greater and therefore representative of operation in the proper direction. A backup method is also provided for sensing the ambient temperature of the air downstream of the condenser coil, both before and during motor operation to determine whether the temperature during motor operation is greater than that prior to operation to thereby indicate a proper connection.
