The present invention entails a power switching system for a tractor-trailer that can be selectively actuated to direct power to the tractor unit from an auxiliary power source such as a refrigeration unit mounted on the trailer. When the tractor-trailer is in a parked position, power can be furnished to the tractor and to energy consuming components thereof through an auxiliary power source carried by the tractor-trailer, thereby improving the total fuel economy of the rig. In the power switching system of the present invention, there is provided a swit...


A method of supplying power from an auxiliary power source to the tractor portion of a tractor-trailer rig comprising: operatively interconnecting switch means between an auxiliary power source and the battery of the tractor engine; selectively actuating the switch means and directing power from the auxiliary power source to the tractor and certain energy consuming components thereof; preventing the tractor from being started when power is being directed to the tractor from the auxiliary power source; and providing an oil and water heater circuit and con...
