Abstract
A controller including a controller input coupled to an engine magneto for monitoring tractor engine operation by monitoring a change in magneto signal thereby determining if the engine is running. A power output circuit coupled to an output from the controller draws current from a tractor battery for powering an auxiliary component when the tractor engine is running and disrupts power to the auxiliary component when the tractor engine is not running to conserve battery life.
