An automatic field load check testing system includes a computer communicating with and commanding a rescue hoist. A processor of the computer commands the rescue hoist to wind to build a load on a cable. As the tension builds a sensor monitors an overload clutch to determine if any friction discs in the overload clutch slip as the load builds. When the load reaches a minimum clutch slip load, the load is relieved. Where the friction discs slip before the load reaches the minimum clutch slip load, the overload clutch fails the test. Where the friction discs do not slip before the load reaches the minimum clutch slip load, the overload clutch passes the test.
