Bobcat Tractor Glow Plug Switch

My CT5555 has a 5-position ignition switch. This switch has 2 positions that will turn the glow plugs on. For Manual Glow Plugs you turn the spring-loaded switch back to the Glow Plug position and hold until you have run them to your satisfaction or the glow plug timer turns them off, whichever is first. The ON position on the ignition switch, if left for more than a couple seconds, will initiate the Auto Glow Plug system. The Auto Glow Plug system will determine the engine coolant temperature and then turn the glow plugs on for a predetermined amount of time in relation to the coolant temp.
