The tip electrode pin engages an inner conductor coil at a proximal end and engages a proximal end of the helical anchor electrode at a distal end. The business sector or service sector may monitor or limit utilization of the auxiliary device. The ECU is preferably operative to provide a selected delivery pressure to the brake chamber without measurement of delivery pressure to the brake chamber. The belt guards protect foreign objects from entering the belt drive platform. The oscillating current is adjusted by adjusting a current flow through the external resistor and the second reference transistor.
