An electrical system controller that sends an electrical current disable signal to an electrical switch for an electric vehicle's power steering pump motor upon a speed sensor providing input to the controller when the electric vehicle becomes stationary. A vehicle door position sensor senses when a door of the electric vehicle changes from open to closed and provides a door-open-to-closed input signal to the controller. The controller sends a signal to the electrical switch to reactivate a supply of electrical current supply to the power steering pump motor when a vehicle door position sensor senses that a door of the electric vehicle has changed from open to closed.
